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

Reproductive suppression of giraffe (Giraffa camelopardalis) under managed care using a GnRH immunological product

Giraffe present unique contraception challenges as males persistently pursue females during estrus. Year‐round pursuit during frequent recurring estrus can pose significant risk under slippery conditions. Complete ovarian suppression is a useful tool in giraffe because it eliminates estrous behavior, interest from the male, and controls reproduction. Effective reproduction control in giraffes has been achieved with porcine zona pellucida, oral melengestrol acetate, and depot medroxy‐ progesterone acetate. However, these methods allow some degree of folliculogenesis and estrous behavior. Improvest® is a

Main threats and habitat characteristics to West African giraffes

Les girafes de l’Afrique de l’ouest (Giraffa camelopardalis peralta) vivent en petites populations isolées au Sud-est du Niger et partagent leur espace de vie avec la communauté locale. La girafe fait face à de nombreuses menaces directes et indirectes dans l’ensemble de son aire de distribution. L’objectif de cette étude est d’identifier sur le plan historique les changements et les menaces de la conservation des girafes de l’Afrique de l’ouest. Ainsi, pendant la recherche, les publications de 1970 à 2019

Leaving by staying: Social dispersal in giraffes

Dispersal is a critical process that shapes the structure of wild animal populations. In species that form multi-level societies, natal dispersal might be social (associated with a  different social community while remaining near the natal area), spatial (moving away from the natal area while continuing to associate with the same community), or both social and spatial (associating with a different community and moving away from the natal area). For such species, classical spatial measures of dispersal, such as distance moved,

An Exploratory Study into the Influence of Sex on Body Measurements, Carcass Weights and Meat Yields of Giraffe (Giraffa camelopardalis angolensis)

Various body measurements and commercial carcass yields of relatively young (2 1/2 –6 yrs old) giraffe (Giraffa camelopardalis angolensis) were investigated to quantify the effect of sex there upon. Eight male and eight female giraffe were culled by standard practice in Namibia, where body and horn measurements were taken, before the carcasses were dressed. There were no significant differences between the mean dead weights of the two sexes (bulls = 691.1 kg; cows = 636.5 kg; p = 0.096), the
