Pensoft at the European Small Mammal Conservation Conference 2026

The inaugural conference took place in Sofia, Bulgaria, bringing together researchers, conservationists and practitioners to address gaps in small mammal research and monitoring. 

The inaugural European Small Mammal Conservation Conference (SMCC 2026) took place in Sofia, Bulgaria, from 21 to 25 September 2026, bringing together researchers, conservationists and practitioners from across Europe and beyond to address gaps in small mammal research and monitoring.

Organised jointly by the Habitat Foundation, the Institute of Biodiversity and Ecosystem Research at the Bulgarian Academy of Sciences, the Dutch Mammal Society and Mammal Conservation Europe, with support from the Faculty of Biology at Sofia University, the conference formed part of the Life for Falcons project, funded by the EU LIFE Programme.

This year’s conference was held jointly with the 33rd Hamster Working Group and the VIII European Ground Squirrel Meeting, making hamsters and sousliks the primary focus, alongside broader topics including renewable energy development, agricultural impacts, reintroductions, predator–prey interactions and innovative methodologies in small mammal research.

Pensoft’s Participation

We were delighted to participate in SMCC 2026 with an exhibition booth, showcasing the breadth of publishing services we offer to the biodiversity and conservation community. It was a pleasure to present our portfolio of journals dedicated to advancing research across ecology, biodiversity and conservation.

We were particularly proud to present the following journals:

Meeting delegates from across the small mammal research community was tremendously rewarding, and we thoroughly enjoyed discussing how our journals can support and amplify their work.

Beyond our academic offerings, we were particularly excited to showcase beautiful art prints illustrated by our in-house scientific illustrator, Denitsa Peneva. The collection featured stunning depictions of otters, olinguitos and hamsters.

Conference Highlights

The scientific programme was exceptional, and we were privileged to attend many outstanding presentations that demonstrated the importance of innovative monitoring approaches and conservation action.

Lessons from Citizen Science for Small Mammal Conservation Monitoring in Great Britain

We were delighted to attend a talk by Matt Larsen-Daw, Chief Executive of the Mammal Society (UK), which presented a portfolio of citizen science programmes designed to address distribution knowledge and population monitoring across Great Britain. The programmes, united by the Mammal Mapper smartphone app, included the National Harvest Mouse Survey, the Searching for Shrews initiative, and the University Mammal Challenge. 

The presentation highlighted the value of standardised effort data, the differing trade-offs between structured and opportunistic recording, and the potential for these approaches to be applied across European contexts.

Strong Decline of Hamster Populations in Bulgaria

We were equally impressed by Nedko Nedyalkov’s presentation documenting the significant decline in distribution and abundance of both the common hamster (Cricetus cricetus) and the Romanian hamster (Mesocricetus newtoni) across Bulgaria. The research revealed that population reductions, detected through owl pellet analysis and trapping methods, likely began in the 1950s with agricultural intensification and continue today. 

Given that both species are strictly protected under the EU Habitats Directive yet lack active conservation projects, the presentation substantiated the urgent need for targeted conservation measures. We are also pleased to note that Nedko serves as a subject editor for two of our open-access journals, ZooKeys and the Biodiversity Data Journal.

Reintroduced Saker Falcons and Their Dependence on European Ground Squirrels

Yana Andonova’s presentation on the diet of Bulgaria’s reintroduced saker falcon population provided compelling evidence of the breeding birds’ overwhelming dependence on the European ground squirrel (Spermophilus citellus) as a primary food source.

Through food-remain analysis, visual observations and camera-trap monitoring, the research documented that ground squirrels comprised over 80 per cent of identified prey items, with small rodents accounting for 89 per cent overall! It is also worth mentioning that Andonova is an author in our open-access Biodiversity Data Journal.

Looking Forward

Attending SMCC 2026 was a genuine pleasure and particularly meaningful given that the conference took place in Sofia, the city in which our company is based. Connecting with researchers and conservationists working at the forefront of small mammal conservation, and sharing our commitment to advancing biodiversity research through open-access publishing, reinforced our dedication to supporting this important field. 

We look very much forward to engaging with this community again at future events!

New species of flying squirrel from Southwest China added to the rarest and ‘most wanted’

Described in 1981, the genus Biswamoyopterus is regarded as the most mysterious and rarest amongst all flying squirrels. It comprises two large (1.4-1.8 kg) species endemic to southern Asia: the Namdapha flying squirrel (India) and the Laotian giant flying squirrel (Lao PDR). Each is only known from a single specimen discovered in 1981 and 2013, respectively.

Recently, in 2018, a specimen identifiable as Biswamoyopterus was unexpectedly found in the collections of the Kunming Institute of Zoology (KIZ), Chinese Academy of Sciences by in-house expert Quan Li. It had been collected from Mount Gaoligong in Yunnan Province, Southwest China.

Initially, the individual was considered to belong to the “missing” Namdapha flying squirrel: a species considered as critically endangered due to hunting and habitat loss. The latter had not ever been recorded since its original description in 1981 and was already listed as one of the top 25 “most wanted” species in the world by the Global Wildlife Conservation.

However, a closer look at the specimen from KIZ made it clear that the squirrel exhibited a colouration, as well as skull and teeth anatomy, distinct from any of the previously known species in the genus.

Subsequently, joined by his colleagues from China (Xuelong Jiang, Xueyou Li, Fei Li, Ming Jiang, Wei Zhao and Wenyu Song) and Stephen Jackson from Australia, the team of Quan Li conducted a new field survey. Thus, they successfully obtained another specimen and, additionally, recorded observations of two other flying squirrels. As a result, they included a third member to the enigmatic genus: Biswamoyopterus gaoligongensis, also referred to as the Mount Gaoligong flying squirrel. This new to science species was described in a paperpublished in the open-access journal ZooKeys.

“The morphological features of B. gaoligongensis are closer to the critically endangered and missing Namdapha flying squirrel, but is still readily identifiable as a distinct species,” explains Quan Li.

“The new species was discovered in the ‘blank area’ spanning 1,250 km between the isolated habitats of the two known species, which suggests that the genus is much more widespread than previously thought. There is still hope for new Biswamoyopterus populations to be discovered in between or right next to the already known localities,” he says.

As for the conservation status of the newly described species, the researchers note that it inhabits low-altitude forests which are in close proximity to nearby human settlements. Thereby, they are vulnerable to anthropogenic threats, such as agricultural reclamation and poaching.

“Therefore, there is an urgent need to study the ecology, distribution, and conservation status of this rare and very beautiful genus,” concludes the lead author.
