Reproductive failure in female Thornicroft’s giraffe (Giraffa camelopardalis thornicrofti) in Zambia
Reproductive suppression is common among mammals residing in cooperative social systems and is characterized by the cessation of ovulation in subordinate females until their social environment releases them from a temporary freeze on ovulating (e.g., dwarf mongoose, Helogale parvula (Creel, Creel, Wildt, & Monfort, 1992); African wild dogs, Lycaon pictus (Creel, Creel, Mills, & Monfort, […]
Reproductive life history of Thornicroft’s giraffe in Zambia

Giraffe have two fairly unusual reproductive patterns among large mammals: they can become pregnant while lactating, and calf mortality is extremely high. Longitudinal records are largely absent, so tracking reproductive parameters tends to combine information from captive and field studies. In this […]
