A Preliminary Study of Desert Dwelling Giraffe (Giraffa Camelopardalis Angolensis) Ecology, Northwestern Namibia
Historically, giraffe (Giraffa camelopardalis Linnaeus 1758) were widely distributed throughout Mrica, from the northern to the southern savannah regions (Skinner & Smithers 1990;East 1998). ,Today their distribution is both patchy and discontinuous, from west Mrica to south Africa. Similar to other megafauna throughout Mrica (e.g. elephant (Loxodonta africana), rhino (Diceros bicornis) and buffalo (Syncerus caffer), […]
Spotted hyenas (Crocuta crocuta) follow migratory prey. Seasonal expansion of a clan territory in Etosha, Namibia
The spatial organization of one clan of spotted hyenas Crocuta crocuta in the centre of the Etosha National Park, Namibia, is described during the dry and the wet seasons. The clan comprised 11 adults and sub‐adults and occupied a territory of 160 km2 in the dry season and 320 km2 in the wet season. The dry season territory contained […]
Does illegal hunting skew Serengeti wildlife sex ratios?
In this article we show that the population of Serengeti Masai giraffes Giraffa camelopardalis tippelskirchi is extremely female biased, particularly among newborns. Our results suggest that this might be a response to heavy illegal hunting and the continuous disturbance such activities cause on giraffes, as sex ratios were more female skewed in all age groups in areas […]
Subspecific assessment of the North American captive giraffe population compared to extant giraffe populations across Africa
Approximately 25% of the North American captive giraffe population (n = 125) was compared to a large data set of wild-sampled giraffe from 28 national parks, refuges, and protected areas in Africa (n = 403). The wild-sampled individuals are a part of a larger study being conducted by the International Giraffe Specialist Group (IGSG) towards […]
Spotlight on the Masai Giraffe
Thousands of years ago, the giraffe (Giraffa camelopardalis)–whose exotic appearance led the ancients to speculate it was an unnatural cross between a camel and a leopard–was common throughout all of Africa, Southern Europe, and India, but later became restricted to Africa. As recently as 800 years ago, giraffe disappeared from North Africa as a result […]
Impacts de l’occupation des sols sur l’habitat la girafe au Niger et enjeux pour la sauvegarde du dernier troupeau de girafes de l’Afrique de l’Ouest
The giraffes of Niger (Giraffa camelopardalis peralta) live freely in an environment highly colonized by man called, the zone of transition of the Reserve of Biosphere of the W Regional Park of Niger. The agricultural practices in synergy with the high demographic pressure and the recurring droughts infer an accelerated degradation of the natural forest […]
Correlates of survival rates for 10 African ungulate populations: density, rainfall and predation
1. Through reconciling census totals with population structure, annual survival rates were estimated for the juvenile, yearling and adult stages of 10 ungulate species over 14 years or longer in South Africa’s Kruger National Park. During this period four species maintained high abundance levels, while six species declined progressively in abundance. 2. Multiple regression models […]
Gazing at a giraffe gyroscope: where are we going?
Giraffe are popular animals to watch while on wildlife safaris, and feature prominently in zoos, advertisements, toys and cartoons. Yet, until recently, few field studies have focused on giraffe. We introduce this giraffe topic issue with a review essay that explores five primary questions: How many (sub) species of giraffe exist? What are the dynamics […]
The composition and function of all-male herds of Thornicroft’s giraffe, Giraffa camelopardalis thornicrofti, in Zambia
Temporary all-male social groups are formed in a number of animal species. We examined 34 years of data collected from 36 male Thornicroft’s giraffe in the Luangwa Valley, Zambia, to test a set of predictions related to five possible functions of all-male herds (predator protection, practicing aggressive skills, prolonging life, nutritional demands and resource learning). […]
Linking social and pathogen transmission networks using microbial genetics in giraffe (Giraffa camelopardalis)
Although network analysis has drawn considerable attention as a promising tool for disease ecology, empirical research has been hindered by limitations in detecting the occurrence of pathogen transmission (who transmitted to whom) within social networks. Using a novel approach, we utilize the genetics of a diverse microbe, Escherichia coli, to infer where direct or indirect […]
