From field trip to first paper: the colorful arable fields of Lemnos, Greece

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.

Guest blog post by Lina Rinne

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.

Sun-shunning thief: new plant species robs underground fungi to survive

Tiny and highly specialised, Thismia malayana belongs to a group of plants known as mycoheterotrophs.

Researchers in Malaysia have discovered a tiny and distinctive plant that steals its nutrients from underground fungi.

Published as a new species in the open-access journal PhytoKeys, Thismia malayana belongs to a group of plants known as mycoheterotrophs. Unlike most plants, mycoheterotrophs do not perform photosynthesis. Instead, they act as a parasite, stealing carbon resources from the fungi on their roots.

The 2 cm-long plant’s unusual adaptation takes advantage of the mycorrhizal symbiosis, which is usually a mutually beneficial relationship between colonising fungi and a plant’s root system.

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.

A team of botanists from the Forest Research Institute Malaysia (FRIM) collaborated with local naturalists and stakeholders to make the discovery in the tropical rainforests of Peninsular Malaysia. It was there they found the miniscule species hidden amongst leaf litter and growing near tree roots and old rotten logs.

The research team identified Thismia malayana in two locations: the lowlands of Gunung Angsi Forest Reserve in Negeri Sembilan and the hilly dipterocarp forests of Gunung Benom in the Tengku Hassanal Wildlife Reserve, Pahang.

Despite its small size, Thismia malayana is very sensitive to environmental changes and has been classified as Vulnerable according to the IUCN Red List criteria. Its limited distribution and the potential threat from trampling due to its proximity to hiking trails underscore the importance of continued conservation efforts.

10. The delicious wild oak mushroom

It’s amazing that edible species, long known to local communities, can still present a novelty for science. This was the case with Cantharellus veraecrucis, a chanterelle from – that’s right, Veracruz, Mexico.

During the rainy season, locals harvest this mushroom from tropical oak forests to sell it or enjoy it as a delicacy; this is probably why they’ve dubbed it “Oak mushroom”.

9. The master of disguise

If you ever see a leaf insect, there’s a good chance you won’t notice it – these little critters are masters of camouflaging.

This picture was taken in 2014, when Jérôme Constant and Joachim Bresseel from the Royal Belgian Institute of Natural Sciences were enjoying a night walk in Vietnam’s Nui Chua National Park. It wasn’t until this year, though, that this beauty got its own scientific name: Cryptophyllium nuichuaense. Named after the park where it was found, it is one of 13 new species of leaf insects described in our journal ZooKeys this February.

This leaf insect, like many others, is endemic to Vietnam. This is why the researchers who found itcall for the creation of more protected areas in order to keep this precious biodiversity intact.

8. The Neil Gaiman spider

Unlike most spiders, trapdoor spiders don’t use silk to make a web. Instead, they live in burrows lined with silk that they cover with a “trapdoor”. They are relatively widely spread, but you’d rarely encounter one out in the open, because they spend most of their lives underground.

This is probably why arachnologists and spider lovers the world over got so excited when Dr. Rebecca Godwin (Piedmont University, GA) and Dr. Jason Bond (University of California, Davis, CA) described 33 new species of trapdoor spiders from the genus Ummidia – in addition to the 27 already known.

Dr. Rebecca Godwin talks to L. Brian Patrick about her discovery of 33 new species of trapdoor spiders on his podcast New Species.

One of the 33 is Ummidia neilgaimani, named after fantasy and horror writer Neil Gaiman. A particular favorite of Dr. Godwin, Gaiman is the author of a number of books with spider-based characters. His novel American Gods features a character based on the West African spider god Anansi and a World Tree “one hour south of Blacksburg,” not far from the type locality of this species. He’s also part of the documentary Sixteen Legs, in his own words “An amazing film about Tasmanian cave spider sex.”

“I think anything we can do to increase people’s interest in the diversity around them is worthwhile and giving species names that people recognize but that still have relevant meaning is one way to do that,” says Dr. Godwin.

7. The deadly Chinese-goddess snake

Bungarus suzhenae was only described as a new species this year, but its reputation preceded it – in a bad way. Researchers were already familiar with a notorious black-and-white banded krait that bit herpetologists on expeditions in Myanmar and China – in one infamous case, to death. After extensive morphological and phylogenetical analysis, the researchers were finally able to confirm it as new to science.

The story behind B. suzhenae’s name is interesting, too: it was named after a character from the traditional Chinese myth ‘Legend of White Snake’. The powerful snake goddess Bai Su Zhen is to this day regarded as a symbol of true love and good-heartedness in China. 

Snakebites from kraits – including this one – are known to have a high mortality. This is why the new knowledge on B. suzhenae and its description as a new species are essential to the research on its venom and an important step in the development of antivenom and improved snakebite treatment.

6. The ephemeral fairy lanterns

Commonly known as “fairy lanterns”, plants of the genus Thismia are very rare and small in size. They are mycoheterotrophic, which means they live in close association with fungi from which they acquire most of their nutrition. They’re also very elusive, growing in dark, remote rainforests, and visible only when they emerge to flower and set seed after heavy rain.

In fact, researchers were only able to find one specimen of the new T. sitimeriamiae, which they discovered in the Terengganu State of Malaysia – the rest of the population had been destroyed by wild boars.

Just discovered, T. sitimeriamiae may already be threatened by extinction – which is why the research team that discovered it suggest that this exceptionally rare plant is classified as Critically Endangered.

Described 28 years post-collection, new grass species makes a strong case for conservation

Originally collected 28 years ago in Ecuador, new species Poa laegaardiana has been just described, only to find out its prospects for surviving in its type location seem bleak nowadays. The study was published in the open access journal PhytoKeys.

When roaming in the Cordillera de los Andes of Ecuador, near the village of Facundo Vela, little did Smithsonian scientist and author, Dr. Paul M. Peterson, know that a small grass specimen will not only turn out to be an intriguing new species, but will also make a big statement on the importance of conservation.

Scientific drawing showing what makes new species P. laegaardiana distinct from its congeners

Almost three decades after its original collection the new species P. laegaardiana has finally emerged from its herbarium collection, but the story took an unexpected twist.

It took the authors a single Google Earth search to find out that what used to be the natural habitat of the newly found densely tufted bunchgrass, is now occupied predominantly by small farms.

Heavy agricultural use of the terrain, poses a good possibility for P. laegaardiana to have already been extirpated from this location. With the species currently known only from this area, chances are that this newly described species, might in fact turn out to be already extinct.

“Further studies are needed to search the area and browse collections for specimens from different locations,” explains Dr. Peterson. “But, in fact, it may well be that with our study we are documenting a possible extinction of a species, happening in the space of just 30 years. The story of P. laegaardiana serves to show how human-induced habitat loss can indeed be a major threat to the survival of life on Earth.”

The new species was named after renowned Danish botanist Simon Laegaard, who has made extensive collections in South America, Greenland, Ecuador, and Bolivia (accompanied by the authors) contributing to the documentation of the flora to make informed conservation and management plans.

New species with heart-shaped fruits inspires a love for biodiversity in Hawai’i

Just in time for Valentine’s Day, botanists from Hawai’i have discovered a new species of plant with small heart-shaped fruits. The new species is a member of the coffee family (Rubiaceae) and part of the genus Coprosma, which occurs across many remote islands of the Pacific Ocean. They named the new Hawaiian species after the symbol of love – calling it Coprosma cordicarpa – meaning the Coprosma with heart-shaped fruit. Their research is published in the open-access journal PhytoKeys.

 

The botanists, who discovered C. cordicarpa, describe their finding as the result of a loving adventure with Hawaiian biodiversity. It began when Hawai’i’s State Botanist Dr. Maggie J. Sporck-Koehler noticed the little heart-shaped fruits in the Kanaio Natural Area Reserve on the Island of Maui, while attending a work meeting with the Department of Land and Natural Resources (DLNR), Division of Forestry and Wildlife (DOFAW).

 

One of the primary mandates of DOFAW is to conserve Hawai’i’s native ecosystems and the species that reside in them. As State Botanist, Sporck-Koehler is most often working on issues relating to rare or State and Federally listed threatened and endangered (T&E) plant species. Gaining a better understanding of native Hawaiian plant conservation status and helping to facilitate conservation efforts is one of the main objectives of the work she does for the State. Therefore, when something extraordinary gets under her nose, such as an unusual Coprosmapopulation, she takes a note and a sample.

 

Sporck-Koehler attempted to identify the species using a key so that she could know what she was looking at. She got to Coprosma foliosa, but was not satisfied. So, she turned to Dr. Jason T. Cantley, who at the time was finishing his PhD research on the genus Coprosma at the University of Hawai’i at Manoa Department of Botany. “I was very taken with it,” Sporck-Koehler told Cantley. “It seemed different than any other [Coprosma] foliosas I’ve seen.”

Then, Cantley concluded that the heart-shaped fruits and other characteristics looked different enough that it was worth it to visit specimens at the Bernice Pauahi Bishop Museum in Honolulu, and then to examine the plants themselves. “We needed to get all our ducks in a row, making sure we knew what we were looking for before we flew to Maui,” Cantley says. “Part of that planning was to think about the long-term conservation of Coprosma cordicarpafrom the start. That’s one reason it was necessary to bring Dr. Chau into this project.”

 

Dr. Marian M. Chau is the Seed Conservation Laboratory Manager at Lyon Arboretum’s Hawaiian Rare Plant Program in Honolulu. The Seed Conservation Lab‘s mission is to aid in the prevention of extinction of Hawaiian plant species by maintaining a long-term seed bank collection, to propagate plants for use in approved restoration projects, and to conduct research on seed storage and germination for the Hawaiian flora. The Seed Conservation Lab currently stores over 11 million seeds from about 40% of all Hawaiian native species, with the ultimate goal to represent the entire flora with research and/or long-term germplasm collections. This includes under-described biodiversity, like the heart-shaped fruits of C. cordicarpa.

 

From early on, it was clear that C. cordicarpa was not all that common, as it can only be found on one island. In fact, the botanists determined the new species fell within the International Union for Conservation of Nature (IUCN) Red Vulnerable Category (VU) for extinction risk. The VU is the lowest of the three threatened Red List categories, but indicates that C. cordicarpastill faces threats of extinction in the wild. Chau suggested that they collect seeds for long-term germplasm storage at the Seed Conservation Lab.

 

Two field adventures on Maui and many herbarium specimen measurements later, the authors were confident they were looking at a new species. All in all, 609 seeds from 32 plants were collected, which are going to help preserve the biodiversity of this species for many years to come.

 

The authors had a passion for Hawaiian plant biodiversity and conservation well before this project, but it was the discovery of the heart-shaped fruits that brought these three botanists together. With their naming of this new species, they hope to also inspire others with a love for biodiversity that will continue long into the future.
