This project examined how temperature, sex, month, and time of day affect giraffe (Giraffa camelopardalis) activity in Namibia. Prior to my involvement, giraffe were tagged with a device capable of collecting date, time, latitude, longitude, and temperature data. A generalized additive mixed model was created using the software R with data collected over 9 months. Daily activity plots were produced and indicate that giraffe are crepuscular and their movement is strongly adapted to extreme temperatures.
