Contemporary floristic research is based on quantitative and standardized approaches, supported by various tools for identification and data analysis. However, historical data on the flora of particular regions still serve as an essential foundation. It was precisely this historical context that motivated our research, now available inItalian Botanist.
Nearly two centuries ago, botany in Central Europe began to emerge as an independent scientific discipline, a process in which amateur botanists played an important role. During the 1830s and 1840s, botany was often referred to as scientia amabilis and experienced significant expansion, reflected in the rapid increase in described plant species and intensified exploration. At that time, Dalmatia appeared “exotic” to researchers from continental Europe, but also highly attractive for study, particularly because many of its areas remained poorly explored.

We were intrigued by references to lesser-known botanists appearing in Central European botanical journals of that period. Our aim was to identify who these individuals were, what their contributions had been, and how their research was conducted and organized. In this context, the work of Roberto de Visiani, professor of botany and director of the Botanical Garden in Padua, is essential. He gathered a wide network of collaborators across Dalmatia and significantly contributed to the systematic study of its flora. His Flora Dalmatica is the result of such collaborative efforts.

Among these collaborators, Joseph Martin Neumayer (1791-1840) stood out. Although described by his contemporaries as “an industrious and intelligent collector of plants” and “a living encyclopedia”, his life and scientific contribution remained largely unknown, and even basic biographical details were recorded incorrectly. This gap became the main impetus for our research.

In addition to reviewing historical scientific literature, the most valuable sources were letters exchanged between Neumayer and Visiani, preserved in the archives of the Botanical Garden of the University of Padua. The research was further expanded through archival material from the State Archives in Dubrovnik, as well as parish birth and death records. Through these sources, a picture gradually emerged of a highly dedicated and enthusiastic researcher, fully committed to fieldwork and the development of herbarium collections, which he exchanged with leading botanists of his time.

The letters reveal that botanical expeditions were demanding and often risky, conducted in the rugged mountainous regions of the Dubrovnik hinterland and Montenegro, as well as in the malaria-prone areas of the Neretva valley. Thanks to these efforts, many plant species from these regions were recorded for the first time. Neumayer also proved to be a “Renaissance-type” researcher, extending his interests beyond plants to mosses, lichens, amphibians, and various groups of insects.
This research reminds us that behind every scientific endeavor, both in the past and today, stand curiosity, perseverance, and a deep commitment to one’s work.

Biological invasions are a major driver of biodiversity loss and invasive pollinators can reshape native plant-pollinator networks. A new study published in the journal NeoBiota, reveals that invasive pollinators are fundamentally reshaping native plant-pollinator networks in Chile, leading to a “silent takeover” that threatens the stability of one of the world’s most unique biodiversity hotspots.
Chile functions as a “biogeographical island,” isolated by the Andes Mountains, the Atacama Desert, and the Pacific Ocean. While this isolation has created a highly specialized ecosystem, it also makes the region particularly sensitive to change.
Despite this vulnerability, Chile has a long history of introducing non-native bees for agricultural purposes. A collaborative team of Chilean and Brazilian researchers sought to understand and quantify the long-term impact of these introductions, specifically focusing on how non-native pollinators like the Bombus terrestris (the buff-tailed bumblebee) affect native species.

To assess the impact, researchers analyzed over 2,100 records, merging historical scientific data with citizen-science data. They focused on three non-native species: the western honeybee (Apis mellifera), the buff-tailed bumblebee (Bombus terrestris), and the large garden bumblebee (Bombus ruderatus).
The motivation was to understand whether these invasions were simply adding species to the system or quietly transforming it from within.
еxplains Dr. Rafaela Cabral Marinho, the lead author of the study
The study’s key finding points to the overwhelming dominance of Bombus terrestris, which accounted for more than 70% of recorded interactions in the combined dataset.
That level of integration into a national pollination network is remarkable for a relatively recent invader.
notes Dr. Barbara Guimarães, one of the researchers
Аlso, the invasive bees showed strong interaction with non-native plants and displayed highly generalist behavior. To further measure the impact on pollination networks, the team compared data from before and after 2005, the year B. terrestris began to be used extensively in open fields. They identified a concerning shift: native species like Bombus dahlbomii were being gradually displaced.
The networks did not collapse; instead, they became more generalized and homogenized. Native bees were not always disappearing completely. The system kept functioning, but in a different way. This quiet reorganization is what led us to describe the process as a ‘silent takeover.

The study also highlighted the vital role of public engagement.
We were surprised by the volume and value of citizen science contributions, and how they can provide meaningful insights when combined with research data.
says Dr. Fontúrbel, one of the researchers
This proved that citizen science is an essential tool for detecting and tracking the spread of invasive species in ecosystems, providing direct information for conservation actions.
A call for interaction-based conservation

One key takeaway is that biological invasions are not always catastrophic overnight events. They can be gradual reorganizations of ecological relationships. While invasive bees may increase pollination for certain crops, they can simultaneously reduce the specialization and stability of native mutualisms. Over time, this may lead to biotic homogenization, ecosystems becoming more similar to one another and less unique.
add the researchers
“Our research highlights that conservation is not only about protecting species, but it is also about protecting interactions,” they conclude.
The researchers advocate for coordinated policies regarding species introductions, early detection monitoring, and continued public engagement to safeguard the integrity of Chile’s biodiversity.

From fieldwork to first publication in the journal Vegetation Classification Survey, Lina Rinne reflects on her research in Lemnos, Greece. Alongside Erwin Bergmeier and Stefan Meyer, she tracks her path from a 2024 field trip to a 2025 publication, exploring the island’s unique agro-ecosystems.
I was introduced to the island of Lemnos during a university field trip in 2024, while I was still a master’s student. At the time, I admittedly questioned Erwin’s and Stefan’s choice of destination—why not go to a “cool” island like Crete? However, now, after two visits to Lemnos, I have to say that this island is very special. As my very first scientific publication focuses on this island—and was selected as an Editors’ Choice paper in the last quarter of 2025—Lemnos will always have a place in my heart.
The path to that publication was anything but straightforward. Fortunately, my supervisors and co-authors, Erwin and Stefan, supported me throughout the entire process.
Erwin Bergmeier and Stefan Meyer are well known to researchers working on arable plant diversity, whether in Greece, Germany, or beyond. They have been involved in numerous projects, and only a few people know arable fields, their plant species, and communities better than they do.
Their work on Lemnos began in 2018 as part of the Terra Lemnia project , a local initiative established by the Mediterranean Institute for Nature and Anthropos (MedINA). The project aims to understand and preserve the island’s arable plant diversity and to support farmers to maintain the less intensive, “traditional” agriculture on the island.

On Lemnos, most agricultural fields are used to grow rain-fed fodder crops for sheep and goats. As they are mainly interested in biomass, eradicating wild arable plants (“weeds”) would be more costly than simply tolerating them. This farming reality has allowed an exceptionally high diversity of arable plants to persist—a central focus of our study.
During the master’s field trip in spring 2024, Erwin and Stefan introduced us to the island, the Terra Lemnia project, and local farmers. We explored a wide range of landscapes and attractions: the medieval castle overlooking the island’s capital Myrina, the wetlands and salt lakes in eastern Lemnos, the Ammothínes—striking inland sand dunes resembling a small desert—and Poliochni, often referred to as the “oldest city in Europe”.
At the time, arable plants played only a minor role in my perception, and I certainly did not expect that my academic journey would soon lead me back to Lemnos—and specifically to its agricultural fields.
That changed when I started my PhD in July 2024 with a research focus on Greek agro-ecosystems. We decided to use Lemnos as the basis for my first publication, contributing to the VCS Special Collection“Vegetation classification of islands and archipelagos”. Given my familiarity with the island and the extensive vegetation survey data collected by Erwin and Stefan over several years, it was the perfect starting point.
In January 2025, Erwin and Stefan handed me their dataset, wished me “good luck,” and I began working through the data in R. It was a learning process in every sense. Many species were unfamiliar to me, and even online resources did not always provide clear answers. Gradually, however, my understanding of the data—and of the community patterns it contained—improved. This was greatly helped by accompanying Erwin and Stefan during their fieldwork on Lesvos and Lemnos in spring 2025.
Standing in the agricultural fields and seeing species I had previously known only from spreadsheets and photographs brought the data to life. It also reinforced just how unusual Lemnos is from a Central European perspective. Many people of my generation grew up surrounded by heavily managed and sprayed fields, where a single red poppy is a photo-worthy sight.
In contrast, the cereal and pulse fields of Lemnos are colorful: yellow Brassicaceae grow alongside seas of red poppies, the pink flowers of Agrostemma githago (which is basically eradicated in Germany), and so many Trifolium species that it was difficult to keep track of them all.

During our fieldwork, I learned a lot from Erwin and Stefan. We sampled additional fields for our study, and Erwin pointed out the soil differences (from sandy to loamy) that translated into the vegetation patterns revealed in the data analysis. I also took many pictures and notes to remember the fields and the species.
Fieldwork in Greece, of course, also comes with its own rewards: bathing in hot springs or the Mediterranean Sea, enjoying local dishes grown on the very fields we studied, encountering rare and fascinating bird species (including flamingos!), and meeting local colleagues and friends. Some of them joined us during fieldwork or helped us talk to local farmers, which provided valuable insight into agricultural management practices on the island and their socio-ecological context.
Back in Germany, it was time for a major overhaul of the analyses and manuscript. I incorporated what I had learned during fieldwork, and together with my co-authors, we integrated their extensive knowledge of Lemnos’ agro-ecosystems and arable plant communities.
By May, the writing and revision process was in full swing. Drafting, discussing, revising, and finalizing figures and tables continued until July, when we finally submitted the manuscript to Vegetation Classification and Survey.
As my first publication, the peer-review and production process has been a steep learning experience, involving multiple rounds of revisions and corrections. In the end, however, it was immensely rewarding.
We are very happy to have drawn attention to this remarkable island and to the often-overlooked topic of arable plant biodiversity. Lemnos is well worth visiting in spring (or any other season)—whether for its colorful fields, the diversity of migrating birds, unique landscapes, historical landmarks, or great food. Just be prepared for strong winds and surprisingly cold temperatures; at times, I wore nearly all my clothes at once to stay warm.

Australian botanists have newly identified Solanum nectarifolium, or the Tanami Bush Tomato, from historical specimens collected near the northern edge of the Tanami Desert.
Specialized Organs for Feeding Ants are First of Their Kind.
LEWISBURG, Pa. — A recent study led by Bucknell University Professor Chris Martine, biology, the David Burpee Professor in Plant Genetics & Research, has identified and described a new species of bush tomato with a special connection to ants — a taxonomic journey sparked by unusual specimens held in Australian herbarium collections.
The study, co-authored by a set of Australian botanists and Jason Cantley — the former Burpee Postdoctoral Fellow in Botany at Bucknell who is now Associate Professor of Biology at San Francisco State University — was published in the open-access journal PhytoKeys and underscores the critical role that natural history collections play in biodiversity science. The new species, Solanum nectarifolium, or the Tanami Bush Tomato, was named for the location of its original collection area — the northern edge of the Tanami Desert — and for the uniquely conspicuous nectar-producing organs on the undersides of its leaves.

Martine first had an inkling that something was unusual about the plants from that region of the Northern Territory while working on a project with another former Burpee Postdoc, Angela McDonnell, now an Assistant Professor at St. Cloud State University. The pair included DNA extracted from two herbarium specimens representing Solanum ossicruentum, a species known as the Blood Bone Tomato that the Martine Lab described in the same journal in 2016, in an ongoing analysis meant to build a new bush tomato evolutionary tree.
“We couldn’t understand why the two collections of the same species kept showing up in different parts of the tree,” says Martine. “I had collected one of them and was certain that it represented Solanum ossicruentum, so I reached out to the person who collected the other one, David Albrecht, and asked whether he thought the plants he saw in 1996 at a place called Jellabra Rockhole could be something else.”
Albrecht, Senior Botanist at the Northern Territory Herbarium at Alice Springs, suggested that the best way to know would be for botanists to revisit that remote region of the northwestern Tanami Desert and see for themselves. Martine, who had participated in seven collecting expeditions to northern Australia since 2004, wasn’t disappointed.
“I was kind of hoping he’d tell me that,” Martine says. “Because I was already planning some new fieldwork in the Northern Territory and this would give me a great season to visit an area I had never been to before. But to really be prepared for a trip like that, I first needed to understand what other botanists had recorded and collected there in the past – and there is only one surefire way to do that: check what is in the herbarium collections.”
So Martine started by using the Australasian Virtual Herbarium (AVH), a database of every plant specimen held in every herbarium in Australia. He searched for collections made of Solanum ossicruentum and a similar species called Solanum dioicum in the northern Tanami, finding 15 records for specimens gathered as far back as 1971.

“It was a really interesting distribution of points on the map, too,” Martine says. “These were far south of the other records for Solanum ossicruentum, with hundreds of miles of ‘empty’ country between the two clusters. I couldn’t wait to get to Australia to see what those Tanami plants looked like.”
In May 2025 Martine headed to Australia to meet his team for the trip: Cantley and paper coauthors Kym Brennan, Aiden Webb, and Geoff Newton, all associated with the Northern Territory Herbarium at Palmerston. But, first, Martine made a stop in another plant collection in the southwestern city of Perth.
“The visit to the Western Australian Herbarium was my first chance to spend a bunch of time with some of the actual specimens that I had earmarked based on the data in AVH,” Martine explains. “And what I saw there legit blew my mind.”
Every specimen looked similar to Solanum ossicruentum, except for a few subtle characteristics – and one thing that Martine had never seen in more than two decades of Outback botanizing.

“On the backs of the leaves, along the veins, were these visible round disks,” Martine notes. “They were each around a half-millimeter wide, really obvious, and the only bush tomato specimens that had them – we’re talking hundreds and hundreds of collections – were the ones from the northern Tanami.”
Martine thought they could be extrafloral nectaries (EFNs), non-flower organs on a plant that exude sweet liquid, typically as a means to attract ants that might protect the plants from herbivores. These were known to exist in a few Australian bush tomatoes, but those are tiny and have only been confirmed with microscopes. EFNs that could be seen without magnification would be something truly novel.
A few days later, Martine was in the herbarium at Palmerston and found the same pattern: more visible disks and only on plants from that same geographic area. Then he noticed that the most recent collection, from 2021, had been made by Kym Brennan – a renowned field biologist with an expertise in photography who was preparing for their trip in the next room.
“I ran in there and asked whether he remembered anything unusual about that collection – and before I could finish my explanation for why, he was already showing me an incredible photo of the leaves of that same plant. They were positively oozing with shiny, round droplets of nectar. And all from those disks on the veins.”

Eight days and more than 1000 kilometers of driving later the team arrived near Brennan’s collection site 50 kilometers southwest of the community of Lajamanu, right along the edge of the unpaved Lajamanu Road.
“This was more-or-less the same place where others had collected it in the early 1970s, so we were cautiously optimistic that we’d not only find it there again, but that the plants would have the flowers and fruits on them that we needed to describe this as a new species,” explains Martine. “But it’s a harsh environment and the abundance of bush tomatoes is often dependent on fire occurrence. Sometimes you get to a place and there is nothing but old gray stems. Other times there are more happy plants than you can count. In this case, it was the latter situation!”

The team got to work taking notes, making measurements, and shooting photographs. And then Cantley called for Martine to come over to the plant he was examining. There were ants all over the leaf undersides, avidly moving from disk to disk and probing them for nectar. Hypothesis confirmed.
The collaborators decided on the scientific name “nectarifolium” – which translates to “nectar leaf,” for obvious reasons – and the English-language name Tanami Bush Tomato. Martine then contacted a few experts about the conspicuous nature of the EFNs and whether that has been seen anywhere else in the genus Solanum, a group of around 1200 species that includes the tomato, potato, and eggplant.
“As far as we know, this is the first Solanum species to be described as having extrafloral nectaries that you can see with your naked eye. That’s a pretty cool finding – and it all started with the examination of specimens that have been waiting in herbaria for as long as a half-century for someone to come along and take a closer look.”
Bucknell’s own Wayne E. Manning Herbarium, which holds approximately 25,000 plant specimens, now includes new samples of the Tanami Bush Tomato. But the official holotype remains at the Northern Territory Herbarium in Palmerston — almost 10,000 miles away from Bucknell’s campus.

“The Manning Herbarium may be small, but every specimen is a snapshot of biodiversity,” Martine says. “These collections allow us to study where species occur, how they’ve changed over time, and — in cases like this — even help discover new ones.”
The publication of the new species comes amid broader concern over the fate of natural history collections, such as Duke University’s recently announced closure of its herbarium housing more than 800,000 specimens. Martine and his colleagues agree that such closures could hinder future discoveries and conservation efforts.
Martine, a leading expert on Australian bush tomatoes, was recently elected president-elect of the Botanical Society of America. He will begin his term as president following the organization’s annual meeting in August 2026.
“It still doesn’t feel real and probably won’t until I start my term just after Botany 2026,” Martine says. “But I promise to do my best because plants are awesome and so are botanists.”

As the dedicated communication partner of the project, Pensoft will lead efforts to popularise a new early detection paradigm targeting forest pests in Europe
The issue of pest proliferation is felt more acutely than ever in the wake of globalisation and climate change. As pests and pathogens spread across biomes, the threat to forests and the health of the plants within is only increasing. Cognisant of this worrying trend, the European Union has actively pursued mitigation and prevention measures over the last few years. Grassroots efforts are also on the rise as insights from academia and citizen science alike improve monitoring capabilities on the ground.
To address the core of the problem in its entirety, greater coordination and innovation across the board are required.
It is with this tenet in mind that FORSAID: FORest Surveillance with Artificial Intelligence and Digital Technologies –first emerged on the scene as a Horizon Europе-funded project.
The goal of FORSAID is the inception and deployment ofa technology-based early detection system for EU-regulated forest pests.
The pursuit of that very goal brought together 17 partner organisations from 10 countries. FORSAID is funded by the European Union’s Horizon Europe research and innovation programme. Having officially started in September 2024, it is set to continue until February 2028.
Within the team, Pensoft has taken the lead in the domains of Communication, Dissemination and Exploitation. Its long-standing expertise vis-a-vis public campaigns for science initiatives will be harnessed in an attempt to show the benefits and solutions that the latest digital innovations can bring to plant health monitoring. Thus, Pensoft is to help maximise FORSAID’s impact and ensure its long-term legacy.
The project will be presented across the public domain by following a tailored communication plan. Examples of its implementation include social media campaigns, regular updates of a dedicated FORSAID website and synergies with various stakeholder groups.
Foresight in FORSAID
The project consortium firmly believes that digital innovation is the key to a truly effective pest detection framework. This signifies the central role of technology at all stages of this paradigm’s development process.
More specifically, the employment of digital tools will proceed on several levels:
Satellite and drone surveillance will be employed to remotely map out forested areas of interest and assess the extent of plant damage caused by pests and pathogens.
Smart traps and DNA barcoding will serve to identify and sort out different species of pests.
Artificial intelligence (AI) models will assist throughout this process as it helps to automate the procedure, thereby increasing efficiency.
Building on the technology-based research and experimentation, insights from a variety of stakeholders will also be gathered to crystalise FORSAID’s approach.
The consortium’s intent here is the consolidation of a network of interested and involved actors who would ensure the long-term application of the project’s results. A special focus is also placed on citizen scientists, whose practical needs will be considered in the design of the digital tools developed within FORSAID. Finally, a detailed economic analysis will assess the early detection framework and its associated technological instruments, in order to ensure its usability in the long run.
The FORSAID project consortium at the project’s kick-off meeting held on 26 September 2024 in Padua, Italy.
If you follow any of Pensoft’s social media accounts, you will know that we have been counting down our top 10 favourite species described as new-to-science in our journals this year.
The list is—of course—entirely arbitrary, but it is also a fun way to look back on a year in which several weird and wonderful animals, plants and fungi were discovered.
In this blog post, we will tell you more about each species, share some honourable mentions, and reveal our number 1 spot!
Honourable mentions
The league of legends crab
Gothus teemo and Teemo.
When it was time to name a tiny, ‘furry’ new species of gorilla crab from China, researchers drew unlikely inspiration from the video game League of Legends.
Gothus teemo was named after the character Teemo thanks to its distinctive appearance and has drawn a lot of attention from fans of the franchise.
The new species is thought to have resembled a modern sandtiger shark (pictured).
Calling anything on this list a ‘new species’ is not accurate—rather, they are just new to published science. Nothing exemplifies this more than Palaeohypotodus bizzocoi, a long-extinct shark species that lived 65 million years ago, shortly after the fall of the dinosaurs.
What makes this discovery remarkable is that it was partially accidental. Find out how a 100-year-old box of teeth in Alabama led to the discovery of this ancient shark below.
Sometimes, it is the way in which a new species is discovered that makes it so special.
Such is the case for Schiedea waiahuluensis, a carnation species from Hawaii that is likely the first plant to be identified and collected using drone technology. Learn all about it below!
With its all-black colouration, Tylototriton gaowangjienensis, a crocodile newt from China, has drawn comparisons to Toothless from How to Train Your Dragon.
However, this alluring amphibian hides flashes of orange beneath its tail and toes! Find more pictures and information below.
Besides its adorable appearance, Hoplitis onosmaevae is remarkable due to its distribution. It is currently only known from a small region of the French Alps, and areas >2,000 km away in the mountains of Turkey and Iraq.
Another interesting aspect of Hoplitis onosmaevae is its specialised ecological niche: it is thought to only collect pollen from Onosma species. This narrow ecological niche makes it vulnerable to factors like climate change and changes in agricultural practices.

The discovery of Amalophyllon miraculum—in an area assumed to be a barren agricultural landscape of plant extinctions—represents an inspiration for biodiversity conservation. This “miracle” plant, as its name suggests, was found surviving in one of the small, isolated forest fragments that remain in the Centinela region of western Ecuador.
This spiky amphibian was discovered on Cerro Candelaria, a mountain in the Tungurahua province. The discovery of this new species in the upper Rio Pastaza watershed suggests this area might be a centre of rapid evolution for these fascinating frogs.
Entomologists and citizen scientists teamed up to discover this new species of flea beetle in the lush rainforests of Borneo. The discovery was made during a Taxon Expeditions trip, where non-scientist people got the chance to work alongside scientists to identify and describe new species.
What makes this discovery particularly exciting is the beetle’s size—it’s actually one of the largest among its relatives! Flea beetles that live in the leaf litter of tropical forests are typically much smaller, and as a result, we know very little about their ecology and diversity.
Discovered in the Red Sea, the ‘grumpy dwarf goby’ (Sueviota aethon) was published as a new species in ZooKeys. You can probably guess how it earned its name! This tiny fish, measuring less than 2 centimetres long, sports a permanent frown thanks to its large canines and fierce expression. Despite its small size, the grumpy dwarfgoby is thought to be a fearsome predator in its coral reef habitat.
Thismia malayanais a mycoheterotrophic plant, meaning it doesn’t photosynthesise. Instead, it acts as a parasite, stealing carbon resources from the fungi on its roots!
By stealing nutrients from fungi, it can thrive in the low-light conditions of dense forest understories where its highly specialised flowers are pollinated by fungus gnats and other small insects.
While the Tiputini velvet worm—Oroperipatus tiputini—may look friendly, it is an accomplished hunter that shoots a sticky substance from a pair of glands to trap its prey. This “living fossil” is a rare and unique invertebrate that evolved over 500 million years ago. The new species was discovered in the Ecuadorian Amazon at the Tiputini Biodiversity Station, which is part of the Yasuní Biosphere Reserve.
They say that life imitates art, and this new gecko species proves that to be true! Researchers in India have discovered a gecko with such a unique and beautiful colouration that they named it after painter Vincent van Gogh. The “Starry Night” gecko, or Cnemaspis vangoghi, was discovered in the Southern Western Ghats and stands out due to the male’s yellow head and forebody with light blue spots on the back, a striking combination reminiscent of the famous painting.
A comprehensive study of the floristic diversity of Agguttinni Territorial Park has documented 141 vascular plant, 69 bryophyte, and 93 lichen species from this unique protected area.
Encompassing over 16 000 km2 of towering mountains, long fiords, lush valleys, and massive ice caps, Agguttinni Territorial Park is a protected area on northern Baffin Island, Nunavut, Canada. This park, and all of Nunavut, is Inuit Nunangat – Inuit homeland in Canada – and the park protects sites and biodiversity stewarded by Inuit since time immemorial.
Agguttinni means “where the prevailing wind occurs” in the Inuktitut local dialect. The park includes important bird areas, key habitats for polar bears and caribou, and numerous important Inuit cultural sites. It is very remote: no roads lead to it, and access is only by helicopter, boat in the summer, or snowmobile in the winter.
Over five weeks in the summer of 2021, Dr. Gillespie’s team traveled across Agguttinni, exploring the vicinity of four base camps in the park on foot and further afield by helicopter. Across this large area, they studied many different habitats from the interior Barnes Ice Cap to the coast of Baffin Bay.
The heads of the long fiords, sheltered far inland, hosted the greatest plant diversity in the park, including numerous species rare on Baffin Island and two species previously only known from farther south in Canada: Lapland Diapensia (Diapensia lapponica) and Flame-tipped Lousewort (Pedicularis flammea). Conversely, the interior plateau near the ice cap was less diverse, but still held new records for Nunavut, such as Powdered Matchstick Lichen (Pilophorus caerulus), Starke’s Fork Moss (Kiaeria starkei) and Sprig Moss (Aongstroemia longipes).
This intensive fieldwork resulted in over a thousand new specimens deposited at the National Herbarium of Canada at the Canadian Museum of Nature and other herbaria worldwide. These pressed and preserved plants and lichens serve as proof that these species were found at this specific place and time and are the foundation for our knowledge of botanical diversity in the park.
Dr. Gillespie and her team also examined over 300 existing herbarium specimens from the park area, most of which were collected in 1950, the last time botanists intensively studied this part of Baffin Island. Combining data from these old and new specimens has resulted in an annotated checklist of the park’s plant and lichen diversity, describing the 141 vascular plant, 69 bryophyte, and 93 lichen species documented in Agguttinni, all native to the Arctic.
This checklist, immensely valuable to park managers and botanists, is filled with descriptions and photos useful to anyone interested in Arctic botany and is out now in the open-access, peer-reviewed journal Check List. With information on which species are present, where they are distributed, and which ones are rare, it will help the conservation and management of the protected area.

An attempt to explore the history of the spread of four non-indigenous invasive tree species in one of the most important Hungarian forest-steppe forests of high conservation value.
Guest blog post by Arnold Erdélyi, Judit Hartdégen, Ákos Malatinszky, and Csaba Vadász
Today, almost everyone is familiar with the term “biological invasion”. Countless studies have been carried out to describe the various processes, and explore the cause and effect, and several methods have been developed in order to control certain invasive species. However, one of the biggest puzzles is always the question of how it all happened. It is not always easy to answer, and, in general, the smaller the area, the more difficult or even impossible it is to answer. In the course of our work, we attempted to explore the history of the spread of four, non-indigenous invasive tree species in one of the most important Hungarian forest-steppe forests of high conservation value, the Peszér Forest (approximately 1000 ha). Last week, we published our study in the journal One Ecosystem.
An open formation of the Eurosiberian steppic woods with Quercus spp., a priority natural habitat type of Community interest under the European Union’s Habitats DirectiveA closed formation of steppic oak forest with a dense shrub layer and a herb layer dominated by the lily of the valley (Convallaria majalis).
The Far Eastern tree of heaven (Ailanthus altissima), as well as the North American black cherry (Prunus serotina), the box elder (Acer negundo) and the common hackberry (Celtis occidentalis) are among the worst invasive plant species in Hungary. They are also responsible for serious conservation and economic problems in the Peszér Forest.

Historical reconstructions of the spread of invasive species are most often based on only one, or sometimes a few aspects. We used six approaches simultaneously:
we reviewed the published and grey literature,
extracted tree species data from the National Forest Database since 1958,
conducted a field survey with full spatial coverage (16,000 survey units (25×25 m quadrats)) – instead of sampling,
recorded all the largest (and presumably the oldest) individuals for annual ring counts,
performed hotspot analyses on the field data
collected local knowledge.

Our results show that each approach provided some new information, and without any of them the story revealed would have been much shorter and more uncertain. We have also highlighted that at the local level, the use of one or two aspects can be not only inadequate but also misleading.
From the literature it was possible to determine the exact place and date of the first occurrence of the tree of heaven and the black cherry. However, in the case of black cherry, for example, it was only possible to piece together the circumstances of the first plantings by combining three different sources. The first occurrences of box elder were found in forestry data. Finally, in the case of the common hackberry, searching for old individuals and determining their age gave the best results.
Common hackberry in the Peszér forest according to the recent forestry data (2016) and the field survey (2017-2019). The difference is clear: in the official forestry database, the tree species is underrepresented several times over
A well-explored story of a biological invasion can go a long way in making more and more people understand that controlling these non-indigenous species can only be beneficial. On the other hand, it can also help to strengthen conservation efforts, for example by increasing the volunteer workforce, which can be a major factor in the reduction of certain species. We hope that our work and the approaches we have taken will serve as a good model for exploring other invasion stories around the world.

A research team led by Jacob Maher discovered thousands of online advertisements for weeds that are prohibited in Australia due to their harmful impact on the country’s environment and agriculture.
Hundreds of weeds have been found advertised on a public online marketplace in Australia. Cacti and pond plants were among the most frequently advertised illegal weed species. These weeds are prohibited in Australia due to their harmful impact on the country’s environment and agriculture. Despite this, a research team led by Jacob Maher discovered thousands of online advertisements for these weeds. Their study is published in the open access journal NeoBiota.
Water hyacinth, a notorious invader that was found traded online.
Trade of ornamental plants, the kind grown in homes and gardens, is the major way weeds are introduced to new places. Some ornamental plants can make their way into the environment and become invasive, negatively impacting native species and agriculture. Increasingly, plants are traded on the internet, allowing a wide variety of plants to be introduced to more distant places. A lack of surveillance and regulation of this trade has resulted in the wide trade of invasive species.
In response, scientists from the University of Adelaide have utilised specialised software called ‘web scrapers’ to monitor trade on public classifieds websites. These web scrapers automate the collection of online advertisements. This allowed the researchers to detect thousands of advertisements for weeds over a 12-month period.
Opuntia, a notorious invader that was found traded online.
Despite Australia’s laws banning the trade of harmful weeds, advertisements were observed across the country. Some of the weeds advertised were associated with uses by traders, including food and medicine. The most popular uses were associated with pond and aquarium plants such as filtering water and providing fish habitat.
The researchers recommend that governments adopt web scraping technology to assist in regulating online trade of plants. They also highlight increasing public awareness and seeking cooperation from online marketplaces as solutions to this growing problem.
“Currently, these online marketplaces allow people to advertise and purchase invasive species, whether they are aware of it or not,” says Maher. “Regulation is needed, but we also need to cultivate awareness of amongst plant growers of this issues and we need help from marketplaces to regulate trade on their end.”
The technology developed in this study is now being utilised by biosecurity agencies in Australia to monitor and regulate the illegal trade of plants and animals online.
Through the collaborative efforts of botanists and citizen scientists, these plants have been rediscovered after decades, some even after more than a century.
Deep in the tropical Andes are hiding plants that were discovered and then forgotten; plants that we knew almost nothing about. Now, thanks to the combined efforts of botanists from Germany, Ecuador, Peru and Costa Rica and amateur plant enthusiasts, these plants have been rediscovered, some of them after more than 100 years. The findings were described in the open-access journal PhytoKeys.

The plants belong to Nasa, a genus from the Blazing Star family (Loasaceae) that has long caused headaches to scientists as its delicate but painfully urticant leaves make it difficult to collect. Most of them are rare, highly endemic, and only around for short periods, which makes them even more unlikely to end up in a herbarium collection.
Luckily, today’s scientists don’t have to rely on herbaria as their sole source of material and clues. Thanks to the advent of global networking and the increasing use of free data repositories, there is a lot more biodiversity data now that is available to use and easily accessible, for example as geo-referenced occurrence records and photos. Citizen science platform iNaturalist, where users can, among others, post photographic occurrence records, has turned into a valuable tool for biodiversity scientists, and plays a significant role in the rediscovery of these Andean plants.
One notable species, Nasa colanii, had only been recorded once, in 1978, until the research team came upon a photograph from 2019. This scarcity in records might have to do with the fact that the plant grows in a highly inaccessible region: in a cloud forest in the buffer zone of Peru’s Cordillera de Colán National Sanctuary, at an elevation of 2605 m.

Another species hadn’t been reported for approximately 130 years when iNaturalist users confirmed its existence in 2022 by uploading photographs. Nasa ferox had been known for centuries, but it didn’t get its scientific description until 2000. “Given the location of the park close to the [Ecuadorian] city of Cuenca, and the fact that the important road 582 goes through the park makes it particularly surprising that the species has not been reported in such a long time, even more so if we consider the numerous botanical expeditions that have been carried out in the general region,” the researchers write in their paper. In fact, only a small population of about ten fertile plants of N. ferox has been found, with the plants always growing in sheltered places such as in rock crevices or at the base of shrubs.

Remarkably, the typical form of Nasa humboldtiana called Nasa humboldtiana subspecies humboldtiana was rediscovered after 162 years, when the research team found a specimen in a conserved remnant of montane Andean forest in the province of Chimborazo, Ecuador.

But probably the most exciting discoveries happened when the team found species that have been considered extinct in the wild. Two species of Nasa, namely N. hastata and N. solaria, were believed to share this fate, both from the Peruvian Department of Lima, a comparably well sampled area, given the proximity to the national capital. Until very recently, both species “remained unknown (or almost so) in the wild.” Earlier attempts to recollect these species near their type localities where they have been found some 100 years ago failed and it needed the help of iNaturalist to reveal that they are still present in the area.

Nasa hastata was recently rediscovered, after, for the first time, photos of living plants showed up taken by the sister of one of the authors. Only a handful of plants have since been reported from two sites, some 7 km apart. Similarly, a few dozens of plants have been found so far from N. solaria occurring in four small relict populations in remnants of forest that once covered larger areas in this region.

Observations uploaded to iNaturalist also revealed important information on another species, Nasa ramirezii,providing the first photographs of living plants from Ecuador and the first data on its exact location.
“All these discoveries serve as a reminder that even well-studied regions harbor diversity that can so easily remain overlooked and unexplored, and point to the role of botanists in documenting biodiversity which is an essential prerequisite for any conservation effort.” leading author Tilo Henning from the Leibniz Center for Agricultural Landscape Research (ZALF) says.
“Hopefully, as more scientists and members of the public contribute to the database, and more professionals get involved in the curation, more undescribed or ‘long lost’ taxa will be found. Our examples of the rediscovery of Nasa ferox after 130 years and Nasa hastata after 100 years, both ‘found’ on iNaturalist underscore this point,” the researchers say in their study.
