New records for the Western Balkans cranefly fauna (Diptera, Tipuloidea) with the description of a new Alexander (Diptera, Limoniidae).

The cranefly (Tipuloidea) fauna of the Western Balkans is still poorly known. In this study, occurrence data of 77 species is reported, of which two species are newly recorded for Albania, eight species for Bosnia and Herzegovina, twelve for Croatia, and seven for Slovenia, respectively. A new species, Kolcsár & d'Oliveira, is described from Bosnia and Herzegovina, Montenegro, and Slovenia.

Estimating population density of insectivorous bats based on stationary acoustic detectors: A case study.

Automated recording units are commonly used by consultants to assess environmental impacts and to monitor animal populations. Although estimating population density of bats using stationary acoustic detectors is key for evaluating environmental impacts, estimating densities from call activity data is only possible through recently developed numerical methods, as the recognition of calling individuals is impossible.We tested the applicability of generalized random encounter models (gREMs) for determining population densities of three bat species (Common pipistrelle , Northern bat , and Natterer's bat ) based on passively collected acoustical data.

Insectivorous bats respond to vegetation complexity in urban green spaces.

Structural complexity is known to determine habitat quality for insectivorous bats, but how bats respond to habitat complexity in highly modified areas such as urban green spaces has been little explored. Furthermore, it is uncertain whether a recently developed measure of structural complexity is as effective as field-based surveys when applied to urban environments. We assessed whether image-derived structural complexity (MIG) was as/more effective than field-based descriptors in this environment and evaluated the response of insectivorous bats to structural complexity in urban green spaces.
