Behind the cover: 32.05

Issue 32.05
2018-32x05 Functional_EcologyThe cover of Issue 32×05 shows a barbastelle bat (Barbastella barbastellus) resting on a tree. The barbastelle bat is a forest-dwelling bat, with a special echolocation system. It emits very faint echolocation calls that are inaudible to its prey, nocturnal moths. Once the bat has detected a moth, it even calls ever fainter while closing in. The moth thus cannot hear the attacking bat and fails to elicit its live-saving evasive flight (see paper by Lewanzik and Goerlitz, pp. 1251–1261).

Also in this issue How do newts fight disease? They change their habitat. This FE Spotlight highights Daversa, Manica, Bosch, Jolles, and Garner et al’s paper Continued source level reduction during attack in the low‐amplitude bat Barbastella barbastellus prevents moth evasive flight (also in this issue). The authors used a combination of field data and laboratory experiments to show that habitat‐switching behaviour is an ecologically relevant and potentially important driver of chytridiomycosis in alpine newt populations.
