Over a 5-year period, we studied the crepuscular activities of 13 individual zebras within a focal group held within a managed game reserve....
Poor knowledge of the intraspecific variability in echolocation calls is recognized as an important limiting factor for the accurate acoustic identification of bats. We studied the echolocation behaviors of an ecologically poorly known bat species, Myotis macrodactylus , while they were commuting...
