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:
- Individual-based Ecology – exploring the physiological and behavioural mechanisms that shape ecological processes
- Biodiversity Data Journal – an open-access venue for publishing primary biodiversity data and datasets
- Frontiers of Biogeography – advancing understanding of the distribution of life across the planet
- Nature Conservation – addressing pressing conservation challenges through applied research
- One Ecosystem – promoting ecosystem-level perspectives on environmental and conservation issues
- Vegetation Classification and Survey – dedicated to the study and classification of plant communities
- Research Ideas and Outcomes – a platform for early-stage ideas and results with rapid publication
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!
