Similarities in social calls during swarming indicate interspecific communication between Myotis bat species

Similarities in social calls during swarming indicate interspecific communication between Myotis bat species

Bats employ a variety of social calls for communication purposes. However, for most species, social calls are far less studied than echolocation calls and their specific function often remains unclear. We investigated the function of in-flight social calls during autumn

Noctule bats form mobile sensory networks to optimize prey localization

Noctule bats form mobile sensory networks to optimize prey localization

Social hunting strategies are already known in many animal species whose prey is irregularly distributed in the landscape. Now it has been documented in the case of the Common noctules (Nyctalus noctula) that groups of these animals join together to

Global response of conservationists across mass media likely constrained bat persecution due to COVID-19

Global response of conservationists across mass media likely constrained bat persecution due to COVID-19

Most people lack direct experience with wildlife and form their risk perception primarily on information provided by the media. The way the media frames news may substantially shape public risk perception, promoting or discouraging public tolerance towards wildlife. At the

Analysis of pesticide and persistent organic pollutant residues in German bats

Analysis of pesticide and persistent organic pollutant residues in German bats

Abstract: Bats are strictly protected throughout Europe. They are a highly diverse order of mammals in terms of body size, body weight, migratory behaviour, trophic niche specialisation and habitat use. The latter ranges from urban areas and arable land to

Precipitation in spring can influence reproductive success of bats

Precipitation in spring can influence reproductive success of bats

Bats are characterized by low reproductive rates in contrast with most of other small mammals. This makes their populations vulnerable when inclement environmental conditions such as cold and rainy weather impair the reproductive success of females. The fine-scale effect of

Automated bat call classification using deep convolutional neural networks

Automated bat call classification using deep convolutional neural networks

Identification of bats is most practically done by exploiting the characteristic features of their echolocation calls. This usually involves expert knowledge, expensive equipment and time-consuming post processing of previously recorded calls. Automated solutions exist, but are usually not as accurate

Wind turbines without curtailment produce large numbers of bat fatalities throughout their lifetime: A call against ignorance and neglect

Wind turbines without curtailment produce large numbers of bat fatalities throughout their lifetime: A call against ignorance and neglect

Bats are protected by national and international legislation in European countries, yet many species, particularly migratory aerial insectivores, collide with wind turbines which counteracts conservation efforts. Within the European Union it is legally required to curtail the operation of wind

Bucherscheinung: Artenschutz in Planungs- und Zulassungsverfahren (Andreas Lukas)

“Da Anhang IV der FFH-Richtlinie alle Arten der Fledermäuse erfasst, bilden dieFledermäuse neben den Vögeln die wohl planungspraktisch bedeutsamste Artengruppe”, heißt es in dem neu erschienenen Werk von Andreas Lukas, Rechtsanwalt mit Schwerpunkt Artenschutzrecht. Deshalb dürfte diese Neuerscheinung für Fledermausschützer,
