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

Conservation Status of Giraffe: Evaluating Contemporary Distribution and Abundance with Evolving Taxonomic Perspectives

Giraffe are iconic figures across a range of African landscapes but they are currently under considerable conservation threat. Although they are widely distributed throughout 21 different countries, continent-wide populations have declined considerably over the past several decades, highlighted by the International Union for the Conservation of Nature’s (IUCN) new categorization of giraffe as a single species as “Vulnerable.” Recent genetic studies, however, propose alternative taxonomic categorizations in which giraffe are comprised of four distinct species. These proposed taxonomic classifications have

Distribution Measurement of Cycling Visitors at Nakhon Ratchasima Zoo Using GPS Tracking System

The aim of this study was to investigate visitor distribution by GPS tracking system at Nakhon Ratchasima Zoo. The samples were 122 participants who received GPS tracking and cycled to visit animals around the zoo. The data were categorized into two groups including demographic and travelling profile and top animal exhibit. The result revealed that the most visitors were family, while the member of half visitors were 3-5 people. Most visitors spent their time with cycling less than 2 hours

Exploring the connections between giraffe skin disease and lion predation

Rates at which predators encounter, hunt and kill prey are influenced by, among other things, the intrinsic condition of prey. Diseases can considerably compromise body condition, potentially weakening the ability of afflicted prey to avoid predation. Understanding predator–prey dynamics is particularly important when both species are threatened, as is the case with lions (Panthera leo) and giraffes (Giraffa camelopardalis). Importantly, an emergent disease called giraffe skin disease (GSD) may affect predatory interactions of lions and giraffes. Hypotheses suggest that GSD

Factors Affecting the Survival of Giraffe in Ethiopia

Giraffe are social animals and non-territorial and tend to live in a small group. In Ethiopia there are two species of giraffe; the Nubian giraffe (giraffe camelopardalis) and Reticulated giraffe (giraffa reticulated) occur in southern low lands, east of Omo river including the Mago National Park, Borena and Ogden area. Giraffe populations in Ethiopia diminished over the past century in diversity, density and distribution as a result of illegal hunting, habitat degradation, civil war and unrest, the absence of a

Camera-trap data do not indicate scaling of diel activity and cathemerality with body mass in an East African mammal assemblage

Diel activity patterns of animal species reflect constraints imposed by morphological, physiological, and behavioral trade-offs, but these trade-offs are rarely quantified for multispecies assemblages. Based on a systematic year-long camera-trap study in the species-rich mammal assemblage of Lake Manyara National Park (Tanzania), we estimated activity levels (hours active per day) and circadian rhythms of 17 herbivore and 11 faunivore species to determine the effects of body mass and trophic level on activity levels and cathemerality (the degree to which species

Effect of Head Position Angles on the Blood Flow in the Jugular Vein of Giraffes

The study investigated the effect of the angular position of the head on the blood flow in the jugular vein of giraffes. The vein considered is elastic and collapsible such that its cross-sectional area is not uniform. Transmural pressure causes the blood to move along the vein. Mathematical equations describing the flow were developed, and the vein was considered to be inclined at an angle φ to the horizontal. A finite-difference scheme was used to solve the equations of motion
