The winter activity of bats was studied in an area of Bavaria, Southern Germany, for seven consecutive years (2007–2013). Echolocation calls were recorded in known foraging areas between October and March of each winter, and bats were regularly see

Female robins aggressively defend territories and sing during the non-reproductive wintering phase. During this time plasma levels of testosterone are elevated in free-living females. We investigated if testosterone activates aggression and song by a

We radio-tracked Myotis emarginatus in Upper Bavaria, Germany to identify the key-foraging habitats and to enable an adequate habitat management for this endangered species. The studied females foraged at a distance of up to 8.1 km around their colon

Male robins aggressively defending a feeding territory in winter have low levels of testosterone, while males defending a breeding territory in spring have elevated levels of testosterone. Song is an integrated part of territorial defense during both

SummaryThe idea that copulation might increase predation risk is a classic suggestion [1–3], but empirical evidence to support it is surprisingly scarce. While some early work found decreased vulnerability to predation during mating [2], two lab an
