"All About Giraffes"

The information I presented highlighted the work of Giraffe Conservation Foundation in the field, especially focusing on the Niger giraffe project…as well as a range of current ex situ initiatives designed to provide a better understanding of giraffe biology. To try and cover all bases I attempt to ‘marry together’ the work being done in the wild world with that undertaken in captivity, thus giving my audience of around 50 zoo keepers, students and those with a general interest in

African lion (Panthera leo) behavior, monitoring, and survival in human-dominated landscapes

Chapter 1, “Demography of a persecuted African lion population,” investigates the basic demographic characteristics of a lion population on human and livestock dominated lands where unregulated, retaliatory hunting of both sexes and all ages had occurred for centuries. I also examine the individual characteristics of stock-raiding lions. Chapter 2, “Participatory monitoring of an elusive carnivore on community lands,” I test the inclusion of local communities in wildlife monitoring and conservation, i.e. participatory monitoring, as a method for collecting data on

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 with high risk of illegal hunting. Giraffes were also more vigilant and fled at longer distances in such areas. Such female skewed sex ratios have

The structure and function of giraffe jugular vein valves

When a giraffe (Giraffa camelopardalis) lowers its head to drink, blood could enter the jugular vein from the inferior vena cava or regurgitate from the jugular veins into the cranial veins. We investigated the anatomy of jugular valves in giraffes to establish if they could prevent either of these regurgitations. Jugular vein length and intervalve distances of 396 valves (192 left, 204 right) were measured in 60 veins from 25 adult (11 males and 14 females) and five foetal giraffes.

Collared!

North-western Namibia is a spectacular land of desert mountains, gorges, plains, and ephemeral rivers, and a land of stark beauty and seemingly inhospitable wilderness. It was here that the wildlife vet and capture expert Michael D. Kock came to help attach satellite collars to desert-dwelling elephants and giraffes so that their movements in their vast range could be tracked. Collaring the animals was the easy part. Getting permission to do so, and then finding them, were rather more challenging.

Seasonal movements of giraffes in Niger

The last population of giraffes in west Africa lives in Niger in an unprotected Sahelian region inhabited by farmers and herders. The spatial behaviour of each individual of the population (n = 63) was studied by direct observation during 15 mo. Two-thirds of the population were resident in the tiger bush in the rainy season and in the nearby area of Harikanassou, a sandy agricultural region, in the dry season. Rainy season and dry season home ranges were mutually exclusive

Dystocia in a Rothschild Giraffe Leading to a Caesarean Section

A 9-year-old female Rothschild giraffe (Giraffa camelopardalis rothschildi), weighing approximately 900 kg, at Longleat Safari Park, Wiltshire, UK was presented with dystocia in September 2005. This paper details the surgical and anaesthetic procedures carried out performing a caesarean section to remove a dead male calf and the successful recovery of the giraffe.

Herd composition, kinship and fission–fusion social dynamics among wild giraffe

A variety of social systems have evolved as a consequence of competition and cooperation among individuals. Giraffe (Giraffa camelopardalis sp.) societies are an anomaly because the dearth of long-term data has produced two polar perspectives: a loose amalgamation of non-bonded individuals that sometimes coalesce into a herd and a structured social system with a ﬁssion–fusion process modifying herd composition within a community. We analysed 34 years of data collected from a population of Thornicroft’s giraffe (G. c. thornicrofti, Lydekker 1911)

Diet and Feeding Effects of Introduced Giraffe in the Eastern Cape.

This study presents the results of a study on introduced giraffe diet and feeding effects within the Eastern Cape Province of South Africa. Five sites were selected over a moisture gradient from the mesic east to the arid west of the Eastern Cape to describe giraffe diet and provide baseline data for feeding effect experiments. At each site faecal samples were collected seasonally and diet composition determined by microhistological analysis. Plant species availability was measured using the point intersect method

Investigation report on giraffe skin disease of Ruaha National Park, Southern Highlands of Tanzania

Giraffe Skin Disease (GSD) is a newly observed condition mainly affecting adult and sub-adult giraffes in Ruaha National Park (RNP). For the first time, the disease was observed at Lunda, northeastern part of RNP in November 2000 but the disease was thought to have existed for some time. A seasonal variation in the prevalence has also been observed with more animals being affected during the rainy season compared to those affected in the dry season. This study was undertaken with
