Blood Parameters In Wild Ruminants In Kenya

Blood specimens from shot or drug-immobilized impala (Aepyceros melampus), Thomson’s gazelle (Gazella thomsonii), Grant’s gazelle (Gazella granti), mountain reedbuck (Redunca fulvorupula), blue wildebeest (Connochaetes taurinus), Coke’s hartebeest (Alcelaphus buselaphus cokii), topi (Damaliscus korrigum), eland (Taurotragus oryx), buffalo (Syncerus caffer) and giraffe (Giraffa camelopardalis) have been studied for the following parameters: erythrocyte and leukocyte counts, haematocrit and haemoglobin estimations, and serum calcium, inorganic phosphorus, magnesium and copper values. Both shot and drug-immobilized impala and shot wildebeest and topi had relatively high

Demonstration Of A Carrier State For Cowdria Ruminantium In Wild Ruminants From Africa

Four wild African ruminants, eland (Taurotragus oryx), giraffe (Giraffa camelopardalis), kudu (Tragephalus strepsiceros strepsiceros), and blue wildebeest (Connochaetes taurinus), were experimentally infected with the rickettsia Cowdria ruminantium, the tickborne agent causing heartwater in domestic ruminants. The infections were established, and C. ruminantium was transmitted to naive small ruminants by the vector Amblyomma hebraeum when transmission attempts were made at days 128 (eland and wildebeest), 85 (giraffe), and 24 (kudu) post infection. These wild ruminants, which are natural hosts for the tick vector, and which commonly

Anaplasma Infections In Wild And Domestic Ruminants: A Review

Anaplasma marginale can be transmitted, will grow and can survive in a large number of domestic and wild animals. It is pathogenic in cattle, and usually produces nonapparent or mild infections in other species. Anaplasma marginale has been recovered from cattle, sheep, goats, water buffalo (Bubalus bubalis), white-tailed deer (Odocoileus virginianus), mule deer (Odocoileus hemionus hemionus), black-tailed deer (Odocoileus hemionus columbianus), pronghorn (Antilocapra americana americana), Rocky Mountain elk (Cervus elaphus nelsoni), bighorn sheep (Ovis canadensis canadensis), black wildebeest (Connochaetes gnu),

Les dernières girafes d’Afrique de l’Ouest : sauvegarde assurée ou avenir menacé ?

The last West African giraffes: insured survival or threatened future? — The present paper describes the current situation of the giraffes of Niger. While the giraffe population there has increased from an estimated 49 in 1996 to more than 200 today, they remain extremely vulnerable. As a matter of fact, the abandonment of the local development initiative, begun in 1996, had adversely affected the area inhabited by giraffes from both an ecological and social point of view. This is because

Jugular venous pooling during lowering of the head affects blood pressure of the anesthetized giraffe

How blood flow and pressure to the giraffe’s brain are regulated when drinking remains debated. We measured simultaneous blood flow, pressure, and cross-sectional area in the carotid artery and jugular vein of five anesthetized and spontaneously breathing giraffes. The giraffes were suspended in the upright position so that we could lower the head. In the upright position, mean arterial pressure (MAP) was 193 ± 11 mmHg (mean ± SE), carotid flow was 0.7 ± 0.2 l/min, and carotid cross-sectional area

Vigilance Behavior And Population Density Of Common Large Herbivores In A Southern African Savanna

The study assessed flight behavioural responses of impala (Aepyceros melampus) and kudu (Tragelaphus strepsiceros) to human disturbance and compared densities of common large herbivores across Gonarezhou National Park (nonconsumptive land use) and the adjacent Malipati Safari Area (consumptive land use) in southeast Zimbabwe. Animal vigilance was measured by flight behaviour and compared in terms of area and group size. Distance sampling method was used to collect data on densities of large herbivores including namely; impala, kudu, zebra (Equus quagga), giraffe

Bringing Angolan giraffe back to Angola – is it feasible in Iona National Park, Angola?

Understanding whether giraffe will survive in Iona NP might seem obvious, considering that the area is likely part of their former natural range. However, research on re-introductions suggests that historical occurrence, or a superficial look at the introduction site, is not enough to ensure success. Feasibility studies provide essential information on the current state of the habitat and other social, economic, and ecological factors. A feasibility study is especially important when a long time has elapsed since the extinction of

Towards a global list of accepted species II. Consequences of inadequate taxonomic list governance

Species lists are widely used in legislation and regulation to manage and conserve biodiversity. In this paper, we explore the issues caused by the lack of an adequately governed and universally accepted list of the world’s species. These include lack of quality control, duplicated effort, conflicts of interest, lack of currency, and confusion in the scientific use of taxonomic information. If species lists are to fulfill their role efficiently, then the governance systems underlying their creation must keep pace. Fortunately,

Direct Human-Caused Wildlife Mortalities In Geralle National Park, Southern Ethiopia: Implications For Conservation

This paper aims to report records of direct human-caused wildlife mortalities in the Geralle National Park of southern Ethiopia during the last five years (2013-2017). Our data showed that a total of 102 carcases of wild mammals were recorded during the period under report, representing 13 species most of which are currently globally threatened. On average 21 ± 5 animals were killed each year and nearly three-fourth of affected species and individuals killed were carnivores. Causes of mortality for all

Humans, megafauna and landscape structure – Rock engravings from Namibia encourage a comparative approach to central Europe and southern Africa

This paper deals with reflections that arose after observing prehistoric rock engravings at different locations in Namibia. These observations stimulated comparative considerations with focus on southern Africa and central Europe. Similar to the Aurignacian rock art of European origin, the most common motifs in the Namibian rock engravings are large animals. While in Europe, the species that served as a blueprint for the illustration of Aurignacian rock art have mostly disappeared, the megafauna illustrated on the rock engravings in Namibia
