The external phenotypic variation of brown hares ( Lepus europaeus ) from Türkiye could represent climate-related adaptation, despite low neutral population genetic differentiation. Here, we investigated whether minor occlusal character variation of brown hares, previously used in phylogenetic or phylogeographic contexts in hare species, exhibit phylogenetic or ecogenetic variation in Türkiye, i.e., whether it corresponds to n...

Song complexity has been identified as one song characteristic important in female choice, whereas its role in male-male interactions is less clear and not much is known which song characteristics are specifically important for territorial defense. In Acrocephalus warblers, males seem to increase song complexity towards females but reduce it during territorial disputes. One possibility to reduce song complexity could be achiev...

In this study, we investigated the influence of different weather aspects on breeding performance, food supply and nest-space use in hoopoe offspring ( Upupa epops ). Camera recordings of 88 nests were used to examine how ambient environmental conditions influence food supply, offspring nest-space use and the trade-off nestlings face regarding the two mainly used locations in the nest. Therefore, we provide a comprehensive ana...

Purpose Alveolar echinococcosis is a severe helminthic disease in humans caused by larvae of the fox tapeworm Echinococcus multilocularis. Austria is considered an endemic area with hotspots having up to 45% prevalence (Bagó et al. in Proceedings of the Zoo and Wildlife Health Conference 2019, Berlin, p. 91, 2019). At our facility, we have registered a notifiable increase of animals submitted for the diagnosis of E. multilocul...
