Population Structure of Ungulates in Waterberg National Park, Namibia

Seasonal and demographic factors influencing gastrointestinal parasitism in ungulates of Etosha National Park.

Host-parasite dynamics can be strongly affected by seasonality and age-related host immune responses. We investigated how observed variation in the prevalence and intensity of parasite egg or oocyst shedding in four co-occurring ungulate species may reflect underlying seasonal variation in transmission and host immunity. This study was conducted July 2005-October 2006 in Etosha National Park, N...

A sylvatic lifecycle of Echinococcus equinus in the Etosha National Park, Namibia

Various species of Echinococcus have been described in the past from wild mammals of sub-Saharan Africa. However, it is only recently, that a few isolates have become available for molecular identification; therefore, the involvement of wildlife in the lifecycles of the various cryptic species within Echinococcus granulosus sensu lato is still only partially known. A preliminary survey was unde...

Ecology and epidemiology of anthrax in the Etosha National Park, Namibia.

Analysis of mortality records has revealed distinct patterns in the incidence of anthrax in elephant and plains ungulates. The seasonal peak among the former is in November at the end of the dry season, while among the latter it occurs in March towards the end of the rainy season. Among elephants, there has been a notable spread of the disease to the west of the Park. Age and sex analyses indic...

Population Estimates of Kea in Arthur's Pass National Park

The population dynamics of a local group of Kea (Nestor notabilis) was studied at a refuse dump in Arthur's Pass National Park over the course of three successive summers. The mean number of buds that foraged at the dump during the summer was estimated as 20 juveniles, 10 subadults, and 36 adults. An average of 11% of these birds were females. The number of adults was quite stable across years....
