Socio-economic factors correlating with illegal use of giraffe body parts

Unsustainable hunting, both illegal and legal, has led to the extirpation of many species. In the last 35 years giraffe Giraffa spp. populations have declined precipitously, with extinctions documented in seven African countries. Amongst the various reasons for these population declines, poaching is believed to play an important role in some areas. Giraffes are primarily hunted for consumption and for the use of their body parts as trophies and in traditional medicine. However, the socio-economic factors that correlate with the

Understanding dead space in giraffes, and its application to critically ill COVID-19 patients

Giraffes have long been a subject of study for scientists due to the physiological anomaly their anatomical design can present. The study of the species helps aid in understanding of clinically relevant processes. The long trachea of a giraffe presents the dilemma of exaggerated dead space; however, this physiological problem is surmounted by a narrow trachea when compared to mammals of similar size, thus decreasing potential dead space. As COVID-19 patients in the hospital and ICU can develop COVID-19 associated

Effect of Elephants and Other Ungulates on the Vegetation in Serengeti National Park in Tanzania

This study assessed the effects of elephants and other ungulates on the vegetation in Northern Part of Serengeti National Park (SENAPA) in Tanzania. This study is peculiar since it assessed the effects of elephants and other ungulates on the vegetation in Northern Part of SENAPA which is missing in the literature. The objectives were to determine plant species composition in the Northern Part of SENAPA, examine the effects of elephants and other ungulates on vegetation in the Northern Part of

Inferred giraffe deaths from lightning strikes

In The Origin of Species, Charles Darwin (1859) wrote that: ‘there must be much fortuitous destruction, which can have little or no influence on the course of natural selection’. His reasoning was that some organisms could be ‘the best adapted to their conditions… [but]…destroyed by accidental causes,’ such that ‘natural selection will be powerless’ in these instances. Stochastic factors, such as extreme weather events, can cause fatalities to individuals otherwise well-adapted to their environment. Specific atmospheric conditions create weather patterns

Fibre Size Frequency In The Recurrent Laryngeal Nerves Of Man And Giraffe

An Optomax Image Analyser has been used to carry out fibre-size analyses in six pairs of human recurrent laryngeal nerve and two pairs of recurrent nerves from adult giraffes. In every case the left recurrent laryngeal nerve was found to contain a greater number of large, fast-conducting fibres. Since this nerve is longer than the right, these findings may explain the simultaneous arrival of motor impulses to both sides of the laryngeal musculature.

Phenotypic matching by spot pattern potentially mediates female giraffe social associations

Animal color pattern is a phenotypic trait that may mediate assortative mixing (also known as homophily), whereby similar looking individuals have stronger social associations. Masai giraffe (Giraffa camelopardalis tippelskirchi) coat spot patterns show high variation and some spot traits appear to be heritable. Giraffes also have high visual acuity, which may facilitate intraspecific communication and recognition based on spot patterns. Giraffe groupings are dynamic, merging and splitting throughout the day, but females form long-term associations. We predicted that adult female

Evaluation de la capacité de charge pour les girafes dans la réserve de biosphère de Gadabédji, Niger

Dans le cadre de la conservation de la girafe (Giraffa cameleopardalis perralta L.), huit individus provenant de Kouré ont été réintroduites dans la réserve de biosphère de Gadabédji. Trois ans après cette introduction, il s’avère important d’approfondir les connaissances sur l’écologie de l’espèce. C’est dans ce sens que la présente étude a été initiée dans le but de déterminer la capacité de charge de la réserve de biosphère de Gadabéji (RBG). En effet, les biomasses foliaires totales et accessibles de

Estimating Giraffe (Giraffa Camelopardalis) Population Size And Survival Rates In South Luangwa Valley, Zambia

Giraffe populations across their range have declined significantly over the past 40 years. Recent studies of these declines noted that conservation efforts often lack basic population estimates and descriptions of demographic parameters such as sex- and age-specific survival rates. I addressed those research needs for a geographically-isolated population of giraffes (Giraffa camelopardalis) in South Luangwa Valley, Zambia. During 2016 to 2018, collaborators opportunistically photographed giraffes throughout South Luangwa National Park and adjacent Lupande and Lumimba Game Management Areas. Given that

Skin Papillomas in an Impala (Aepyceros melampus) and a Giraffe (Giraffa camelopardalis)

Viral particles, typical of the papovavirus family, were demonstrated by electronmicroscopy in small papillomas found on the feet of an impala (Aepyceros melampus) and on the face of a giraffe (Giraffa camelopardalis) in Kenya. Histologically the tissues proved to be typical papillomas. The viral particles measured 38 nm and 40 nm in diameter in all tissue sections from the impala and giraffe respectively.

Infrared Thermography in Zoo and Wild Animals

Infrared (IR) thermography is a noninvasive diagnostic screening tool that does not require handling or restraint of an animal. Physiologic or pathologic processes involving changes in surface temperature may be evaluated using this technique. This modern method provides real-time, instantaneous visual images with measurements of surface temperatures over a greater distance. The first medical application of “thermography” was by Hippocrates (ca. 460-375 BC), who used thin layers of mud for his temperature measurements, similar to modern thermography. An area of
