Lifetime reproductive success of female mountain gorillas.
Studies of lifetime reproductive success (LRS) are important for understanding population dynamics and life history strategies, yet relatively little information is available for long-lived species. This study provides a preliminary assessment of LRS among female mountain gorillas in the Virunga volcanoes region. Adult females produced an average of 3.6 ± 2.1 surviving offspring during their li...
متن کاملInbreeding among mountain gorillas has no consequences
"The mountain gorilla population has been falling drastically for many years so we wanted to take a closer look at what effect living in such small populations might have had on them and which consequences many years of inbreeding had had. As it turned out, the damaging genetic variations that usually arise in small, inbred populations were not there," says one of the study's co-authors, the ge...
متن کاملAre the gorillas in Bwindi Impenetrable National Park "true" mountain gorillas?
The gorillas that inhabit Bwindi Impenetrable National Park in Uganda are the least known of the eastern gorillas. Because they are an allopatric population living a minimum of 25 km from the well-studied population of mountain gorillas (Gorilla beringei beringei) in Rwanda and have certain morphological and ecological differences from these gorillas, their taxonomic status has been in question...
متن کاملMinerals in the Foods Eaten by Mountain Gorillas (Gorilla beringei)
Minerals are critical to an individual's health and fitness, and yet little is known about mineral nutrition and requirements in free-ranging primates. We estimated the mineral content of foods consumed by mountain gorillas (Gorilla beringei beringei) in the Bwindi Impenetrable National Park, Uganda. Mountain gorillas acquire the majority of their minerals from herbaceous leaves, which constitu...
متن کاملImpact of Male Infanticide on the Social Structure of Mountain Gorillas
Infanticide can be a major influence upon the social structure of species in which females maintain long-term associations with males. Previous studies have suggested that female mountain gorillas benefit from residing in multimale groups because infanticide occurs when one-male groups disintegrate after the dominant male dies. Here we measure the impact of infanticide on the reproductive succe...
