Pensoft Celebrates World Wildlife Day 2026 with Medicinal and Aromatic Plants

Medicinal and aromatic plants (MAPS) are essential for human health and ecological balance.

This World Wildlife Day, we are celebrating the role of medicinal and aromatic plants (MAPs), which are essential for both human health and ecological balance. To highlight this year’s theme – “Medicinal and Aromatic Plants: Conserving Health, Heritage and Livelihoods” – we have spotlighted six fascinating species from the open-access journal PhytoKeys.

Medicinal Marvels

The Coleus genus, a member of the Lamiaceae (mint) family, comprises approximately 294 species of perennial herbs and subshrubs native to the tropical and subtropical regions of the Old World, including Africa, Asia, and Australia. These plants are well-regarded for their diverse medicinal applications, and are traditionally employed to address respiratory issues such as coughs and bronchitis. The pictured Coleus harmandii species, native to Indo-China, shares the genus’ characteristic antioxidant and anti-inflammatory properties.

Meanwhile, an interesting-looking parasitic plant named Balanophora xinfeniae, and found in the shaded forests of Motuo County in Tibet, exhibits similar properties. A study on its taxonomic identification notes the broader medicinal significance of the Balanophora genus. Indeed, species within this genus are historically used to treat ailments, including liver disorders, stomach aches and hemorrhoids.

Perhaps the most interesting of the bunch are species within the genus Huperzia, commonly known as firmosses, which are highly valued for their ability to treat Alzheimer’s disease. While the newly-discovered species, Huperzia crassifolia, was identified during medicinal plant inventories in China, it belongs to a group of plants that have long been used in traditional Chinese medicine for cognitive health. Because this new species is a close relative of these established medicinal plants, it holds significant potential for future pharmaceutical research.

Fragrant Frontiers

We now shift our focus to aromatic plants, beginning with Capsicum fruits. These are driven by a diverse range of organic compounds, responsible for their characteristic “bell pepper” scent. Pictured below, Capsicum cornutum is a unique pepper known locally in Rio de Janeiro as Pimentinha-do-mato (wild pepper). Its specific aroma is the product of rust-coloured outer hairs, which densely cover its stems and leaves. Unlike many common garden peppers, this species features a continuous ring of glandular hairs, which give it a distinct herbal scent.

Plants within the genus Uvariodendron are also frequently characterised by the presence of aromatic compounds. Their scents are concentrated in the leaves, bark and flowers, ranging from spicy and peppery notes to distinct citrus or anise-like fragrances. These aromatic profiles have served as key diagnostic markers for botanists; for instance, species like Uvariodendron anisatum are named specifically for their scent. Interestingly, the fragrance emitted by the pictured Uvariodendron molundense aids in attracting many pollinators!

PhytoKeys 233: 1-200. https://doi.org/10.3897/phytokeys.233.103096

We end our series with the species Neocinnamomum citratum, a recently described evergreen tree from southwestern China. Unlike other Neocinnamomum species, which typically possess only a faint fragrance, N. citratum is characterised by a strong lemon fragrance present throughout its branches, leaves and bark. This potent aroma is reflected in its specific epithet, “citratum”. Due to these aromatic properties, the species has practical local utility; in Malipo County, for instance, residents collect the branches and leaves to use as spices for cooking.

From the life-saving potential of Huperzia crassifolia to the cultural heritage of Neocinnamomum citratum, these selected species demonstrate that the conservation of wildlife is deeply intertwined with our own survival. Through the protection of these medicinal and aromatic plants, we can safeguard the health and heritage of our planet for generations to come.

New Special Issue in Nature Conservation offers an interdisciplinary resource for wetland ecosystem restoration

New Special Issue in Nature Conservation offers an interdisciplinary resource from over 100 European experts for the better restoration of wetlands, coasts and floodplains

Wetlands are key environmental sentinels. These systems offer a plethora of ecosystem services, acting as biodiversity hotspots and carbon sinks while providing natural buffers against the impacts of climate change.

They also benefit our society by ensuring food security, providing clean water, and protecting coastal communities. In fact, they support more than one billion livelihoods worldwide, as well as 40% of all known plant and animal species.

However, in our rapidly changing world, we face a series of complex, overlapping challenges. To address the ongoing loss of wetlands, new, interdisciplinary solutions are needed that match the scale of the problem.

A Special interdisciplinary resource

In response to these challenges, a new special issue in Nature Conservation titled ‘Wetlands in a Changing Climate: Restoring Coasts and Floodplains,’ aims to bridge critical knowledge gaps, highlight the vital importance of wetland ecosystems, and identify ways to upscale restoration action under the EU Nature Restoration Regulation.

Wetlands in a Changing Climate: Restoring Coasts and Floodplains special issue in the open-access journal Nature Conservation published by pensoft

Edited by Ute Susanne Kaden, Sophia Schmid, Simone Wulf, Katrina Marsden, Carla Klusmann, Aletta Bonn, Klement Tockner and Mathias Scholz, the Special Issue includes 15 peer-reviewed articles with contributions from over 100 European experts across 18 countries. You can read the full editorial here.

Adopting a ‘source-to-sea’ approach, the collection bridges the gap between riverine and coastal research to foster integrated responses to environmental pressures. Its findings are organized into four key thematic sections:

  • Section I: Wetland biodiversity in a changing climate: Understanding their vulnerability
  • Section II: Wetland ecosystem services and nature-based solutions for climate change mitigation and adaptation
  • Section III: Wetland restoration in practice: Opportunities, overcoming barriers and scaling up implementation
  • Section IV: Wetland policy: Enabling a transition towards a resilient future

By synthesizing perspectives from science, policy, and practice across Europe, this collection serves as a transdisciplinary “guide for anyone seeking an integrated understanding of the unique role of European riverine and coastal wetlands in the context of climate change and biodiversity,”. 

While the primary scope is from Europe, these findings offer vital insights applicable to restoration efforts worldwide.

For me, riverine and coastal wetlands are vivid examples of how biodiversity, climate, and human well-being depend on one another, yet they often remain out of the spotlight – making their protection and restoration all the more important. This Special Issue brings together accessible science, practical experience, and policy perspectives, and we hope it will help spark real – and urgently needed – progress in restoring Europe’s coasts and floodplains.

comments Dr. Ute Kaden, one of the lead authors of this Special Issue.

This Special Issue builds on the 5th European Conference on Biodiversity and Climate Change (Bonn, 2023), a collaborative effort organized by the German Federal Agency for Nature Conservation (BfN), the European Network of Heads of Nature Conservation Agencies (ENCA), the Helmholtz Centre for Environmental Research (UFZ), the German Centre for Integrative Biodiversity Research (iDiv), and adel-phi.

Connecting the research and people

Beyond the Special Issue itself, the lead editors organised a free online launch event to present the valuable collection of research publications. On Thursday, 26 February, over 300 participants gained insights into the vulnerability and resilience of riverine and coastal wetlands.

The discussion centered on evaluating the multifunctional benefits of nature-based solutions, sharing restoration lessons from across Europe, and identifying key opportunities аnd challenges in scaling up wetland restoration actions.

Addressing biodiversity climate nexus is important – biodiversity loss and climate change are interconnected and we must strengthen their relationship to develop effective responses to both challenges.

Dr. Kim Grutzmacher, Head of Division International Nature Conservation, BfN

During the launch event, Dr. Flore Lafaye de Micheaux, European Senior Advisor at the Ramsar Convention on Wetlands, reflected on how the importance of wetlands extends beyond their ecosystem value.

Wetlands have been part of human existence since the dawn of time, not only because they have provided for our basic needs, but also because they are places of meaning, culture and spirituality. Our message is that it’s time to invest in wetlands as this means investing in future.

Dr. Flore Lafaye de Micheaux, Ramsar Convention on Wetlands

Research from four major projects, BioAgora, Respin, SpongeBoost, and Rest-Coast, was showcased during the launch event. As an active consortium member in these projects, Pensoft contributes essential expertise in science communication, dissemination, stakeholder engagement, and technological development.

Notably, the lead authors Dr. Kaden (UFZ) and Dr. Scholz (who also serves as the coordinator of SpongeBoost) presented insights from Sections I and II of the new Special Issue. Comprising eight papers from the SpongeBoost consortium, the research tackles pressing ecological challenges, ranging from nutrient retention and floodplain services to the socio-economic valuation of nature-based solutions and the intricacies of EU policy.

Wetland restoration involves human-nature relationships, and wetlands should be treated treated as a social ecological system.

Dr. Mathias Scholz, Helmholtz Centre for Environmental Research

In this Special Issue, you will find in-depth analyses such as the work of Ibáñez et al., 2026, which asks ‘To what extent is coastal wetland biodiversity endangered by climate change? How can we boost the resilience of coastal ecosystems?’ Their research highlights the dual threat of “coastal squeeze” and climate change on Mediterranean wetlands. 

Shifting the focus to inland waters, the issue also features ‘Building blocks for upscaling freshwater ecosystem restoration: Place-based strategies for a transdisciplinary challenge’ by Birk et al. (2026). Drawing on 18 European case studies from the MERLIN project, this research identifies five essential ‘building blocks’ necessary to successfully upscale freshwater restoration efforts.”

New Michelin Star Jellyfish Discovered in Japanese Aquaria

Malagazzia michelin is only the second species of its genus to be found in Japanese waters.

Researchers have reported the discovery of a new species of jellyfish, Malagazzia michelin, marking only the second species of its genus ever found in Japanese waters. Led by Takato Izumi of Fukuyama University, the discovery was a collaborative effort between marine biologists and staff from several prominent institutions, including the Tsuruoka City Kamo Aquarium and the Saikai National Park Kuju-kushima Aquarium. The full study is published in the open-access journal ZooKeys.

First spotted in the shallow waters of Nagasaki and Yamaguchi Prefectures, the Malagazzia michelin jellyfish has subsequently been cultured and studied in captivity, providing scientists with a complete look at its entire life cycle from polyp to adult.

A Unique Marine Resident

Malagazzia michelin is a small aquatic invertebrate characterised by a hemispherical, transparent umbrella that typically grows to between 12 and 20 millimeters in diameter. While it shares the four-lipped mouth and linear gonads typical of its genus, it is easily distinguished by a peculiar feature: enigmatic brown spots that resemble tiny oil droplets scattered across its reproductive organs and central stomach. DNA analysis has confirmed its status as a unique species, which is distinct from other known members of the Malagazzia family.

The species has been aptly named Malagazzia michelin as a playful nod to the famous Michelin Guide. As the jellyfish matures, the number of its distinctive brown spots increases, a process that researchers likened to a restaurant earning more “stars” for its quality. This celestial theme is also reflected in its new Japanese common name, ama-no-gawa-kurage (Milky Way jellyfish), which compares the white gonads and twinkling brown spots to a starry galaxy.

Navigating the Confusion of Common Names

The formal scientific description of M. michelin addresses an interesting challenge in Japanese marine biology: the risk of common names. In Japan, ornamental jellyfish are often given descriptive common names, such as “salmon-roe laodicean jellyfish” (tsubuiri-sujiko-yawara-kurage), long before they are scientifically identified. This can lead to confusion – M. michelin, for instance, was previously misidentified in field guides as a member of the Laodicea genus, which is not closely related. Researchers emphasise that formal taxonomic work is essential to ensure that the biodiversity displayed in aquaria is accurately documented.

The discovery of Malagazzia michelin demonstrates the significant role that aquariums play as centres for scientific research and biodiversity discovery. By strengthening ties between public exhibitions and taxonomic research, scientists continue to bring the ocean’s most stellar species to light.

5000 Students run ‘bee hotels’ across Canada – DNA reveals who’s checking in

Students at the forefront of conservation or how community science helps gather data on cavity-nesting bees and wasps, enhancing our understanding of ecosystem interactions.

Can students be the front lines of conservation? A new Canada-wide study, published in Metabarcoding and Metagenomics, suggests they can. The efforts of some 5000 students produced data detailed enough to reveal complex ecological networks hidden inside a small PVC and cardboard tube home.

They invited schools to volunteer across Canada to install standardised ‘trap nests’ – simple PVC pipe and cardboard tube homes that mimic natural cavities where bees and wasps build nests.

Cavity-nesting bees and wasps play key roles in pollination and pest control, yet their distributions and feeding relationships are often poorly known because they can be small, secretive and difficult to observe directly.

As part of the Bees@Schools community science program, researchers Sage Handler (University of Guelph), Nigel Raine (University of Guelph), and Dirk Steinke (University of Guelph) aimed to address this.

Instead of relying only on traditional identification under a microscope, the researchers used DNA metabarcoding – a method that reads DNA from mixed samples and can detect many species at once.

This allowed the team to identify not only which bee or wasp species built each nest, but also which plant pollen or insect prey were brought back as food. The result was a rich, detailed view of both where cavity-nesting bee and wasp species live and how they interact with plants and other insects.

A key outcome of the study was the creation of tripartite networks: maps linking (1) the nesting bee or wasp, (2) its food (pollen or insect prey) and (3) parasites. This kind of network is extremely difficult to build through observation alone, but trap nests can act like tiny ecological time capsules.

Every brood cell contains biological traces and metabarcoding can recover them. Students weren’t just collecting insects, they were collecting entire ecological interaction datasets: the raw material needed to build food-web maps across a whole country!

A lot of people want to contribute to conservation or learn more about biodiversity, but don’t know how. This shows that a small, practical action, like hosting a trap nest, can contribute real data that researchers can use. Community and citizen science is becoming more common, so keep an eye out for research happening in your neighbourhood.

says Handler, the lead author of the study

Call Me Invasive: New Evidence Confirms the Status of the Giant Asian Mantis in Europe

These mantises are increasingly threatening local biodiversity through aggressive predation and reproductive competition.

In the realm of entomology, few creatures command as much fascination as the mantis. Throughout history, these striking insects have been deeply woven into local myths and legends, sometimes respected as mystical soothsayers that can guide lost travelers home, and other times feared as little devils. 

Today they remain captivating animals, serving as excellent bioindicators of biodiversity, and helping us identify rich and diverse ecosystems when present as native species. 

However, a new study published in the open-access Journal of Orthoptera Research reports that two mantis species identified in Europe – Hierodula tenuidentata and Hierodula patellifera – have been formally recognised as Invasive Alien Species (IAS). This shift in status highlights a growing threat to the biodiversity that native mantises typically help us protect. Led by Roberto Battiston of the Museum of Archaeology and Natural Sciences “G. Zannato”, a team of researchers investigated the impacts of these native to Asia species on European ecosystems which, until now, were largely unknown.

According to Battiston, these mantises have been present in Europe for about a decade, but their numbers have recently exploded in the Mediterranean and continental regions. 

“They are pushing increasingly further north, thanks to climate change,” Battiston explains, noting that viable populations are now frequently spotted by the public in local parks and gardens. Because they are large and fascinating, they often inspire more curiosity than concern, with members of the public frequently wondering if these striking insects are a positive sign for their local environment.

“This study was born to give people those answers and to develop strategies to contain them.”

Hierodula tenuidentata and Hierodula patellifera are large and adaptable tree-dwelling predators, characterised by their high reproductive potential. They are capable of hatching an average of around 200 nymphs per egg case, which is almost double that of the native European mantis (Mantis religiosa). Coupled with their low rate of cannibalism among young nymphs, they are able to grow very rapidly. 

  • Size comparison of patellifera (on the left) and tenuidentata (on the right). (Photo credit: Roberto Battiston).
  • Roberto Battiston (left) and William Di Pietro (right) conducting field research. (Photo Credit: Roberto Battiston).

These species are considered particularly dangerous to local biodiversity because they fatally lure native males into mating attempts that end in the males being eaten, potentially depressing native populations. They additionally consume a wide range of other native species, including essential pollinators like honeybees, and small protected vertebrates such as lizards and tree frogs. These negative interactions demonstrate the need for urgent assessments, particularly in Mediterranean islands with endemic species of invertebrates and vertebrates.

Interestingly, domestic cats have emerged as the primary vertebrate predator of the invasive Asian mantises, accounting for 45% of recorded positive predation events. Battiston notes that while cats serve as an effective means of containment for these invaders, they are unable to distinguish between alien and native species. Consequently, roaming cats also prey on native species like the European mantis, which already suffer competition from their exotic cousins in peri-urban environments and are in decline.

  • Cyanistes caeruleus – Eurasian blue tit. (Photo credit: Alessandra Previtali).
  • Dendrocopos major – Great Spotted Woodpecker. (Photo credit: Alessandra Previtali).

Human-modified environments, particularly in urban and suburban areas, significantly facilitate the expansion of Hierodula mantises. These insects utilise artificial structures, such as insect hotels, as concentrated hunting grounds, and leverage urban heat islands to survive longer into colder months. Thus, by exploiting human infrastructure and localised warming, these mantises are successfully extending their range and survival beyond natural limits.

To mitigate the spread of Hierodula, Battiston mentions the following initiative:

“My colleagues William di Pietro and Antonio Fasano (GRIO) have managed to set up a huge citizen science project and collect over 2,300 reports from enthusiasts and citizens. Citizen science is a fundamental tool not only for monitoring but also for raising awareness and informing people in an active and participatory way about these issues.”

Beyond reporting sightings, the public can also take direct action by intervening during the winter months when trees and shrubs are leafless. During this time, the oothecae – brownish, spongy egg cases about 2-3 cm in size – are well-exposed and easily recognisable on branches. While these cases are easy to remove and their destruction is painless, Battiston cautions that the public should always consult a specialist before removal to ensure that they are not accidentally targeting native mantises.

The expansion of the Asian mantis is a powerful reminder of how human activity shifts natural boundaries and makes active community-led conservation more important than ever. As these adaptable invaders continue to reshape European ecosystems, our collective vigilance and participation in citizen science are effective tools for protecting Europe’s native biodiversity.

C-reactive protein is closely related to cardiac repolarisation in patients with coronary artery disease in contrast to patients with cirrhosis

A new study reveals that different factors affect the relationship between inflammation and heart rhythm stability depending on whether patients are suffering from coronary disease or cirrhosis.

A new study reveals that the predictive power of key inflammatory markers, such as C-reactive protein, shifts fundamentally depending on whether a patient suffers from cirrhosis or acute/chronic coronary disease.

Measured using an electrocardiogram, ventricular repolarisation, which refers to the duration of time the heart muscle takes to electrically “reset” after each beat, is the core indicator of heart health stability.  The main factors governing this essential electrical function are the pumping ability of the left ventricle and the activity of the autonomic nervous system – since systemic diseases like liver failure or coronary blockage disrupt these factors, inflammation often rises.

This study aimed to contrast how the relationship between inflammation and heart rhythm instability manifests across diseases localised in different systems. 

“Most of the knowledge about markers of inflammation such as white blood cell count and C-reactive protein in the field of internal medicine comes from studies in patients with cardiovascular diseases, namely coronary artery disease,” explains doctor Niya Emilova of the University Emergency Medicine Hospital Pirogov in Sofia, Bulgaria, who led the research project. 

“We present a study which is the first contemporary exploration of the differences in inflammation regarding arrhythmia risk and clinical outcome of patients with cirrhosis, stable coronary artery disease and acute myocardial infarction.”

The researchers measured three primary inflammation markers: white blood cell count (the number of infection-fighting cells), C-reactive protein (a protein produced in response to systemic inflammation), and procalcitonin (a highly specific indicator of bacterial infection).

Their paper, titled “C-reactive protein is closely related to cardiac repolarisation in patients with coronary artery disease in contrast to patients with cirrhosis”, and published in the open-access journal Bulgarian Society of Medical Sciences Journal, reveals that C-reactive protein is associated with the risk of ventricular arrhythmias in stable coronary disease, while both C-reactive protein and white blood cell count correlated with repolarisation indices in acute myocardial infarction.

In cirrhosis, only high white blood cell count showed a trend for linking to unstable rhythms; C-reactive protein by contrast did not correlate with heart rhythms in this group.

“The count of white blood cells and procalcitonin are associated with risk of complications in alcoholic cirrhosis. In patients with cirrhosis and infection on therapy, white blood cell count is a specific marker of increased dispersion of repolarisation,” the researchers write in their paper.

Certain medications used to treat heart failure and coronary disease, such as beta-blockers, may have preventive value in reducing the risk of life-threatening cardiac arrhythmias in patients with cirrhosis, the researchers suggest.

Lunar New Year is a celebration of the arrival of spring and the beginning of a new year on the lunar calendar. As the most important holiday in China, it is also widely celebrated across Korea, Vietnam, and other countries with a substantial Chinese diaspora.

In celebration of 2026 as the Year of the Horse, we reviewed our journals for horse-related studies. While our recent publications do not focus on horses themselves, we have highlighted several fascinating species that share an equine connection in their names.

2026 may be the Year of the Fire Horse, but we start our series with a creature of the opposite element: the seahorse!

Monitoring tiny, cryptic pygmy seahorses can be costly and logistically challenging. To overcome this, researchers from Taiwan turned to citizen science, gathering photographs from divers and underwater photographers via social media. Five species were identified, including two never before recorded in the region.

Among them is the charismatic “Japan pig” seahorse, Hippocampus japapigu, originally described from Japan in the open-access journal ZooKeys.

At the time, only seven pygmy seahorses had been identified globally. Documenting five of them in Taiwan established the region among the world’s biodiversity hotspots for these miniature fish.

But seven did not remain the final count for long. In Chinese tradition, eight is considered an auspicious number, associated with prosperity and good fortune.

Enter Hippocampus nalu – the eighth recognized pygmy seahorse species!

Seahorses also feature in a remarkable Mediterranean story…

A study published in Acta Ichthyologica et Piscatoria documented a stable and conspicuous population of the long-snouted seahorse, Hippocampus guttulatus, in a highly polluted coastal lagoon in the Ionian Sea.

Piccolo of Taranto (Ionian Sea), 2011-2013. (Photo credit: Francesco Tiralongo and Rossella Baldacconi).

Through three years of diving surveys, amounting to 69 hours underwater, researchers recorded 196 sightings. The seahorses showed a clear preference for artificial hard substrates, while only a few individuals were found in algal meadows. 

Despite environmental fluctuations and pollution, the population persists. In the Year of the Horse, we wish you the same resilience and strength!

Fish is a traditional Lunar New Year dish, symbolising abundance and good fortune. While you won’t find a horsefish at the markets of Hainan, China, you can certainly spot a ponyfish.

Researchers have reported the first confirmed record of Aurigequula striata in Chinese waters, based on specimens collected at a fish market in Sanya, Hainan Island.

Live seafood markets have long proven to be unexpected hotspots for scientific discovery – just like the remarkable giant isopod Bathynomus vaderi described from market-purchased material in Vietnam.

As fresh as the seafood on display, this discovery was published in late January 2026 in ZooKeys. Newly collected specimens of Aurigequula fasciata enabled detailed morphological and genomic analyses, including the first complete mitochondrial genomes for both species and new phylogenetic insights into the family Leiognathidae.

Fittingly, we close with a horseshoe bat once feared lost. Its name bridges our equine theme with a traditional Chinese symbol: the word for bat (fú, 蝠) is a homophone for blessing (fú, 福), representing happiness and prosperity.

Hill’s horseshoe bat (Rhinolophus hilli), listed as Critically Endangered and unseen since 1981, was rediscovered in Nyungwe National Park, Rwanda, after 40 years.

Otters as ocean doctors: how a 40-year watch on Brazil’s coasts reveals hidden threats to estuaries

Neotropical otters are key for estuarine health, providing insights into ecosystem integrity and pollution impacts.

Guest blog post by Dr. Oldemar de Oliveira Carvalho Junior

For four decades, we’ve been quietly watching otters along the southern coast of Brazil. Not just because they’re charismatic and playful, but because they are among nature’s most honest diagnosticians. Just like a doctor checks your pulse, blood, and behavior to assess your health, scientists can use otters to monitor the condition of estuaries, those vital transition zones where rivers meet the sea.

Published in Estuarine Management and Technologies, our new study, ‘Otters as Bioindicators of Estuarine Health,’ synthesizes 40 years of field data from from Projeto Lontra in Brazil’s Peri Lagoon, along with global ecological research. The findings reinforce the role of semi-aquatic mammals as “living sensors” of ecosystem integrity.

This study is part of the topical collection: Otters as Bioindicators of Estuarine Health: Innovations in Monitoring and Management from Tropical Coastal Brazil

Why otters and not another animal?

Otters sit at the top of the food chain in estuaries. They need clean water, healthy fish populations, connected habitats, and safe denning sites. If any of these elements falter, otters are among the first to respond, with fewer sightings, changes in their diet, or markers of disease.

While a water sample offers only a fleeting snapshot, otters aggregate environmental signals across time and space.

In fact, their very presence, or absence, tells a story. In regions where Atlantic Forest fragmentation has severed the connection between land and water, otter sightings have plummeted by 30% in just a decade.

This isn’t just a loss of biodiversity; it’s a warning for everyone downstream. Fewer otters mean degraded waterways, disrupted food webs, and weakened natural buffers against floods and erosion.

A “living record” of pollution

The diet of otters consists of 70-80% fish, as well as crabs and other aquatic animals. As they consume prey, they also accumulate pollutants, like heavy metals, microplastics, and industrial chemicals, that have built up in those animals. Their bodies effectively become archives of contamination.

Think of an otter as a biological hard drive: by analyzing its scat (feces), we can reconstruct what pollutants are moving through the estuary, even if they’re invisible to the naked eye.

For instance, in Brazil, we’ve found microplastic fibers in otter droppings from protected lagoons, proof that no coastal system is truly isolated from human impact.

The tropical knowledge gap

Globally, over 70% of otter research focuses on temperate species like the Eurasian or sea otter. Meanwhile, the Neotropical otter (Lontra longicaudis) receives less than 4% of scientific attention, despite inhabiting the world’s most biodiverse and threatened estuaries.

This imbalance in the research poses a great conservation risk. Tropical estuaries face unique pressures: rapid urbanization, mangrove deforestation, and climate-driven sea-level rise. Without focused research, we risk managing these ecosystems with tools designed for entirely different environments.

Our work aims to close this divide, establishing the Neotropical otter as a key indicator to drive evidence-based conservation across the Global South.

Land-based diseases in aquatic sentinels

One of our most striking findings showed that 66% of otters tested positive for Toxoplasma gondii – a parasite shed only by domestic cats. How does a land-based pathogen end up in an aquatic mammal? The answer is through runoff.

The rain washes cat feces from the streets, gardens, and informal settlements into rivers and lagoons. This reveals a sobering truth: even within protected areas, otters are exposed to threats originating far inland. To protect these sentinels of ecosystem health, we must implement integrated management strategies that address sewage overflow, urban runoff, and domestic animal impact.

What comes next?

We’re finalizing the Otter Health Index (OHI), a low-cost toolkit for municipalities, NGOs, and community groups to monitor estuaries using simple metrics: spraint frequency, habitat connectivity, contaminant screening, and local knowledge. It’s designed for places with limited labs but rich ecological insight.

After 40 years of observing otters, we’ve learned this: protecting them isn’t just about saving a species. It’s about safeguarding the intricate web of processes that sustain clean water, fisheries, flood resilience, and human well-being.

Otters aren’t just inhabitants of our estuaries; they are their guardians. If we listen to what they’re telling us, we’ll know exactly what these ecosystems need to survive and thrive.

Pensoft Celebrates the International Day of Women and Girls in Science

In honour of the International Day of Women and Girls in Science, Pensoft Publishers celebrates the remarkable contributions of women in our journals’ editorial teams.

Since its inception by the United Nations in 2015, February 11 has marked the International Day of Women and Girls in Science, dedicated to honouring the transformative role women play in the laboratory, field and archives. Despite their undeniable impact, women account for only a third of the world’s STEM researchers and 35 per cent of all STEM graduates, with only one in ten reaching leadership positions.

This year’s theme and celebration is titled “From Vision to Impact: Redefining STEM by closing the gender gap”, and focuses on how new emerging technologies can shape the future of STEM and their impact on gender equality.

While the campaigns of the previous two years urged concrete steps for the promotion of gender equality in science, this year showcases existing good practices and solutions for making STEM environments more inclusive.  

At Pensoft, we champion this mission by amplifying the voices of the women on our editorial boards. By sharing their wisdom, reflections and visions for the future, we hope to foster a more equitable scientific community and inspire the next generation of girls to pursue their passions in STEM.

For young women and girls dreaming of a career in science, Sandy Knapp, co-Editor-in-Chief of the open-access journal PhytoKeys, offers a powerful reminder:

“Keep going and keep doing. Don’t let anyone tell you that science isn’t for girls – it most certainly is. Science is for everyone, and it thrives on diversity. We need all kinds of people to make it truly work.”

As a woman leading a major scientific journal, Knapp also believes that creating a sense of belonging is a shared responsibility:

“We all need to work on this, both women and men. I think we need to not immediately assume subordinate roles – this doesn’t mean shouting and stamping our feet, but rather assuming a quiet and determined excellence.”

  • Knapp conducting fieldwork in Brazil in the 1980s.

She highlights that representation is key to influence, noting that “the more of any minority there are in the room, the easier it is to make your voice heard and your opinions count.” This same spirit of determination defines the advice she would give her younger self:

“Don’t let anyone tell you something is too difficult – it might be for them – but not for you! Believe in yourself.”

  • Knapp at the launch of the Fixing Our Broken Planet Exhibition at the Natural History Museum, London.

Meanwhile, Tammy Robinson-Smythe, co-Editor-in-Chief of the open-access journal NeoBiota, emphasises the sheer excitement of being at the forefront of scientific research:

“Science is an exciting environment to work in. I love the fact that what we discover today is feeding into the textbooks of tomorrow. A career in science is worth all the effort!”

  • Robinson-Smythe conducting fieldwork.

Robinson-Smythe also shed light on the intersection of professional life and family. “Making space for women to be moms while contributing to the scientific community is vitally important,” she explains. To achieve this, she advocates for practical, structural changes:

“By offering childcare on campus and at conferences we can help moms to feel like they belong, rather than feeling like they need to ‘switch off’ motherhood when they arrive at work.”

Reflecting on her own beginnings, Robinson-Smythe’s advice centers on the importance of individual path-finding:

“I’d remind myself that everyone is different. Learn from how others navigate the research environment, but find a way that matches with your morals and goals.”

The co-Editor-in-Chief of the Natural History and Museomics journal, Deborah L. Paul, similarly encourages young women and girls to believe in their dreams – “your motivation matters the most”. To succeed, she suggests surrounding oneself with supportive individuals who say “yes” to those dreams and actively encourage exploration.

When it comes to building a scientific community where women truly belong, Paul believes the responsibility lies in active leadership and self-reflection. She asserts that “we each need to set an example,” which involves constantly questioning current workflows to ensure we are creating “spaces where we can be heard and contribute.”

Reflecting on her own career, she recalls the impact of mentors and offers the simple yet powerful advice:

“Be that person for someone.”

She ends with a heartwarming piece of advice she would have told her younger self when first starting her career:

“Recognise that one’s path through life may not be linear and that’s okay. Know that discovery will lead you to new places and new adventures.”

For Pensoft, celebrating women in science means building a publishing environment where their research is seen, and their voices heard. As we look at insights from senior editors like Sandy Knapp, Tammy Robinson-Smythe and Deborah L. Paul, the message is clear: the field is better when it is diverse.
