Waterhole Dynamics and Chemical Signals of African Elephants (<i> Loxodonta Africana </i>)
… seasons and ambient temperature on the use of a waterhole by elephants as well as the co-occurrence of elephants and other mammals at the waterhole. Biodiversity scans (October 2004-June 2007) and were performed at a permanent waterhole on the Ndarakwai Ranch in northern Tanzania. More elephant …

Variations in the use of artificial waterholes by mammals at Okaukuejo and moringa in Etosha National Park, Namibia
The presence of artificial waterholes can alter local mammal biodiversity. Research on the impact of artificial waterholes on local mammal biodiversity and studies on the nocturnal patterns of water usage are limited in Namibia. In this study, large mammals that visited Okaukuejo and Moringa …

Chemical Signaling and Resource Use by African Elephants (Loxodonta Africana)
… receptive females, and in mixed associations. Waterholes serve to meet the physical needs of elephants and as areas for information exchange, especially for males in search of females. When widely spaced, waterholes may be impacted heavily by elephants. I examined elephant use of a permanent …

Age Effects on Social and Investigative Behaviors in a Closed Population of African Elephants
… elephants during the entry to a signal-rich waterhole and in female African elephants across seasons. Chemosensory and social behaviors were recorded in Addo Elephant National Park between May 2004 and June 2005 using focal animal sampling. During the approach to a waterhole, investigation of …

Effect of Matriarchs on Group Interactions, Kinship Fitness, and Differences In Chemosensory Behavior of African Elephants (Loxodonta Africana)
… their role in interactions between families at waterholes in Addo Elephant National Park, South Africa. I analyzed three hypotheses for matriarchal effects on group fitness: a) older matriarchs provide greater access to resources, b) older matriarchs lead more social groups, or c) there is no …

Sexually Dimorphic Developmental Patterns of Chemosensory Behaviors in African Elephants (Loxodonta Africana)
… behaviors. African elephants were studied at a waterhole in 2004-5 at Ndarakwai Ranch, Tanzania. I identified 277 elephants and 26 distinct female-offspring groups. Sex differences in the chemosensory repertoire and rate of behaviors were evident for subadults but not for the younger age …

The role of territoriality in the mating system of the springbok Antidorcas marsupialis (Zimmerman 1780)
… rainfall and the distance from the nearest waterhole. The social organisation of springbok exposed territorial males to the highest predation risk, whilst males in general risked a higher predation threat than females. This was reflected in both the observed predation and adult survivorship. …
