Abstract:
... Soundscape comprises of a mix of species-specific calls, where individuals compete for acoustic space, yet a different vegetation structure allows for differential call filtration. We focus on an assemblage of bush cricket species in a human-transformed landscape, with a special focus on the seemingly endangered Thoracistus thyraeus. Landscape transformation produces both novel ecological and acou ...

Abstract:
... Scientific interest in debris-covered glaciers (DCGs) significantly increased during the last two decades, primarily from an abiotic perspective, but also regarding their distinctive ecology. An increasing body of evidence shows that, given a minimum of debris thickness and sufficient substrate stability, DCGs host surprisingly diverse plant assemblages, both floristically and structurally, despit ...

Bats may be heavily affected by wind turbines in forests, because many species depend on forest ecosystems for roosting and hunting and can experience high fatality rates at wind turbines. We performed acoustic surveys in 24 t ...
