Reproductive biology of captive Arabian oryx (Oryx leucoryx) in Saudi Arabia
Abstract 10.1002/(SICI)1098-2361(1996)15:43.3.CO;2-P Reproductive data on captive Arabian oryx (Oryx leucoryx) were collected from June 1986 through April 1992 at the National Wildlife Research Center (Taif, Saudi Arabia). Oryx females are polyestrous. The estrous cycle averaged 22 days and mean gestation length was 260 ± 5.5 days (S.D). Sex ratio at birth was unbiased and mean […]
Fitness Consequences of Maternal Rearing Strategies in Warthogs: Influence of Group Size and Composition
Cooperatively breeding species are defined by the presence of individuals who help in rearing the offspring of others. This seemingly altruistic behaviour has been difficult to define and the help provided has not always resulted in a reproductive advantage to the recipient. We examine maternal rearing strategies in the common warthog, Phacochoerus africanus, a facultative, […]
Variation in dental wear and tooth loss among known-aged, older ring-tailed lemurs (Lemur catta): a comparison between wild and captive individuals
Tooth wear is generally an age-related phenomenon, often assumed to occur at similar rates within populations of primates and other mammals, and has been suggested as a correlate of reduced offspring survival among wild lemurs. Few long-term wild studies have combined detailed study of primate behavior and ecology with dental analyses. Here, we present data […]
