Time allocation and patterns of activity of the dorcas gazelle ( Gazella dorcas ) in a sahelian habitat

摘要: The patterns of activity are a reflection the adaptation species to its habitat. This study reports and time allocation dorcas gazelle following their reintroduction process from captivity semi-wild conditions in sahelian Activity three adult males was recorded using GPS collars equipped with temperature sensor acceleration sensors recording two channels, forward–backward (X-axis) sideways (Y-axis). Collars delivered data for 59, 139 151 days. aim this work is assess ability adapt schedule changing environment. main behaviour observed resting (59.8 ± 23.9%), followed by feeding (20.9 ± 10.9%), displacement (15.1 ± 14.1%) running (3.9 ± 5.5%). If eliminated, gazelles invest most (61.0 ± 21.3%) displacements (30.8 ± 15.6%) only 7.6 ± 0.6% running. exhibit activity: one diurnal maximum central hours day, which accounts during dry-cool season (December, January February); bimodal pattern at dust dark, middle day hot-dry (April) transitional March. Temperature driver change patterns; when average exceeds body gazelle, changes bimodal. These results reveal facing environmental native
