Grasshoppers (Orthoptera, suborders Ensifera and Caelifera) are often used as bioindicators to assess the effects of human‐induced land‐use changes. However, such assessment is largely depending on the methods that provide an accurate estimation. In the present study, we compared grasshopper species richness and assemblages on mountainous meadows in the Austrian Alps by applying a commonly used visual‐acoustic...

Habitat fragmentation causes drastic changes in the biota and it is crucial to understand these modifications to mitigate its consequences. While studies on Neotropical bats have mainly targeted phyllostomid bats, impacts of fragmentation on the equally important aerial insectivores remain largely unexplored. We studied species richness, composition, count abundance and feeding activity of aerial...

Alarm calls were induced in adult Wistar rats by an air puff. Emitted calls were digitized and directly recorded on a computer hard drive. The long-duration 22-kHz calls were emitted almost exclusively in series. Initial calls in the series tended to have the longest durations, higher frequency range, and the highest degree of frequency modulation, as compared to other calls. The frequency modulation...
