Die Daten zu den Wiesel-Losungssuchen unserer Spürhunde für die Universität Bern wurden kürzlich in der wissenschaftlichen Zeitschrift "Journal for Nature Conservation" publiziert!! Wir durften als Co-Autoren an der Publikation mitarbeiten! Herzlichen Dank für das Vertrauen, es war eine hervorragende Zusammenarbeit!

The role of small structures for stoats in agricultural landscapes
More to come, auch diese Saison sind wir wieder für die Universität Bern (Institut für Ökologie und Evolutionsbiologie, Abteilung Naturschutzbiologie) unterwegs!!
Wir sind stolz einen Beitrag zum Verständnis zur Wirkung von Fördermassnahmen geleistet zu haben. Dies ist die erste wissenschaftliche Studie, welche die Wirkung von Ast- und Steinhaufen (in der Schweiz äusserst beliebte und staatlich subventionierte Fördermassnahmen) analysiert.
Fazit:
Die Anzahl Kleinstrukturen pro Fläche (Dichte) und die Grösse der Strukturen haben einen positiven Zusammenhang mit der Anzahl Hermelin Nachweisen.
"Scat-detection dogs proved to be remarkably effective for sampling small mustelids in Switzerland, with 97.8 % (true-positive rate) of genetically identified samples belonging to stoats. With our study design, however, we could not evaluate the false-negative rate (false absence) of the detection dogs. Nevertheless, the deployment of dogs enabled the detection of small mustelid presence across the sampled plots to a degree that would not have been possible without their assistance."
"Based on the findings of ths study, we call for the installation of small structures throughout the agricultural landscape to promote small mustelid populations. Combining model prediction and our observations (Appendix I), we suggest installing five or more small structures within a 100-m radius. As larger small structures appear to offer greater benefit for stoats, we recommend a minimum stone pile size of 200 x 200 x 50 cm and branch pile size of 200 x 200 x 100 cm. Stoats play a vital role as predators of water voles and common voles, animals that can have detrimental impacts on agricultural systems such as grassland and fruit tree production. In this context, stoats may act as natural pest control (Boschi et al., 2018, King and Powell, 2007, Mougeot et al., 2020). Although our results indicate the importance of keeping or reinstating stone piles for stoats, we call for the installation of both stone and branch piles to provide habitat features that benefit a diverse array of species, such as amphibians, birds, and reptiles (Castillo-Escrivà et al., 2019, Indermaur and Schmidt, 2011, Manenti, 2014, O’Sullivan et al., 2023, Rossier et al., 2021, Sperry and Weatherland, 2010). By informing conservation strategies, our findings can benefit not only the Swiss agricultural landscapes but also the protection of mustelids at a broader scale."
