Molecular species identification of bushmeat recovered from the Serengeti ecosystem in Tanzania

Bushmeat harvesting and consumption represents a potential risk for the spillover of endemic zoonotic pathogens, yet remains a common practice in many parts of the world. Given that the harvesting and selling of bushmeat is illegal in Tanzania and other parts of Africa, the supply chain is informal and may include hunters, whole-sellers, retailers, and individual resellers who typically sell bushmeat in small pieces. These pieces are often further processed, obscuring species-identifying morphological characteristics, contributing to incomplete or mistaken knowledge

The giraffe and its food resource in the Serengeti. II. Response of the giraffe population to changes in the food supply

The dynamics of the giraffe population of the Serengeti were quantified to ascertain the response of the population to the increasing biomass of the available browse resource. Aerial counts conducted in 1971 and 1976 together with analyses of fecundity and mortality data suggest a rate of population increase of some 5-6% per annum. Compared with the dynamics of a stable giraffe population in Nairobi National Park, the sub-adult components of the Serengeti regional populations are larger and juvenile growth rates

A guide to estimating the age of Masai giraffes (Giraffa camelopardalis tippelskirchi)

This is a guide for estimating the age of Masai giraffes (Giraffa camelopardalis tippelskirchi) with noninvasive methods. Giraffes are commonly categorized into three age classes: calf (0 – 1 year), subadult (1 – 5 years) and adult (> 5 years). This categorization, though somewhat arbitrary, has its origins in giraffe life history. After birth, calves remain with their mothers for 12 – 18 months. Age at first reproduction varies but is usually around 4 – 5 for females and 7

Trypanosome diversity in wildlife species from the Serengeti and Luangwa Valley Ecosystems

The trypanosomes include a number of species that cause disease in livestock. In recent years, several trypanosomes have been identified which do not fit into the classic trypanosome classification system. However, previous work has focused on trypanosomes identified in the tsetse vector, with little information available on trypanosomes found in their natural hosts, wildlife. We studied trypanosome sequences from wildlife in Serengeti National Park in Tanzania and the Luangwa Valley in Zambia and found a number of trypanosome species pathogenic

Giraffe Social Behaviour

Many features recommend the giraffe (Giraffa camelopardalis) for behavioural study: it is big, abundant, conspicuous, active by day, reasonably trusting of people, deliberate, and the best self-marked animal in existence. Surprisingly, its social behaviour has been largely neglected. We studied giraffe exclusively for the following periods: February–March, 1975 and January–December, 1977 in the Serengeti National Park, July 1979–June 1980 in the Arusha National Park, and January–October, 1981 in the Tarangire National Park, totalling 3264 hours of observation directed principally to

Using claw marks to study lion predation on giraffes of the Serengeti

Although lions Panthera leo are the main predators of the giraffe Giraffa camelopardalis, interactions between these species are rarely observed directly. As a consequence, little is known about the effects of lions on giraffe mortality and behavior. We test patterns of lion predation on Masai giraffes Giraffa camelopardalis tippelskirchi using a new methodology: lion claw marks observable on the skin of live giraffes. We studied 702 individually known giraffes in 3 non-neighboring areas of Serengeti National Park, Tanzania between August

Umbilical cord stump retention and age estimation of newborn giraffes (Giraffa camelopardalis)

The umbilical cord stump is a conspicuous characteristic used to identify recently born giraffes (Giraffa camelopardalis) (Foster & Dagg, 1972; Langman, 1977; Leuthold & Leuthold, 1978; Pratt & Anderson, 1979; Pellew, 1981; Dagg & Foster, 1982). However, there is surprising disagreement over the length of time that the umbilical stump remains attached, with reports varying from about 4 weeks (Pellew, 1981; Serengeti, Tanzania: subsp. tippelskirchi) to 6 weeks (Leuthold & Leuthold, 1978; Tsavo East, Kenya: subsp. tippelskirchi) to 60 days

Food supply and poaching limit giraffe abundance in the Serengeti

The iconic giraffe, an ecologically important browser, has shown a substantial decline in numbers across Africa since the 1990s. In Serengeti National Park, Tanzania, giraffes reached densities of 1.5–2.6 individuals km-2 in the 1970s coincident with a pulse of Acacia tree recruitment. However, despite continued increases in woody cover between the 1980s and the 2000s, giraffe recruitment and survival rates have declined and density has dropped to only 0.3–0.4 giraffes km-2. We used a decision table to investigate how four

Food Consumption and Energy Budgets of the Giraffe

(1) To estimate the efficiency of the foraging strategy described in Pellew (1984), the rates of food intake of adult giraffe in the Serengeti National Park are assessed. Daily energy intakes derived from the diet are compared with estimates of the energy requirements for year-round reproduction. The reproductive performance of giraffe in the Serengeti is discussed in the light of such energy budgets. (2) Giraffe are exerting a major impact upon the development of the Acacia regeneration, removing up to

Giraffe Cow-Calf Relationships and Social Development of the Calf in the Serengeti

Activity patterns of giraffe calves and calf-mother distances have been studied as functions of age and sex of the calf in the Serengeti National Park, Tanzania. Particular attention was paid to the nature of the cow-calf bond, suckling behavior, the social development of the calf, relationships between calves and between mother-calf pairs in calf groups, and the anti-predator behavior of mother and calf.
