Abstract Background Videographic material of animals can contain inapparent signals, such as color changes or motion that hold information about physiological functions, such as heart and respiration rate, pulse wave velocity, and vocalization. Euler

Social relationships are shaped by ecological conditions, giving rise to diverse societies even among related species. Among elephants, females exhibit close, often familial bonds with some degree of philopatry and fission–fusion dynamics. Forest e

Acoustic structure of forest elephant rumbles: a test of the ambiguity reduction hypothesis

Autor: Anahita K. Verahrami, Daniela Hedwig, Peter H. Wrege

Publikováno v: Animal Cognition. 22:1115-1128

Quantitative assessments of the structure of vocalizations are a fundamental prerequisite to understand a species' vocal communication system and, more broadly, the selective pressures shaping vocal repertoires. For example, to reduce ambiguity in si

Long-term monitoring of Dzanga Bai forest elephants: forest clearing use patterns.

Autor: Andrea K Turkalo, Peter H Wrege, George Wittemyer

Publikováno v: PLoS ONE, Vol 8, Iss 12, p e85154 (2013)

Individual identification of the relatively cryptic forest elephant (Loxodonta cyclotis) at forest clearings currently provides the highest quality monitoring data on this ecologically important but increasingly threatened species. Here we present ba
