The extent and progression of exposure to feline infectious peritonitis (FIP) virus in the cheetah, Acinonyx jubatus, was monitored by a world-wide serological survey with indirect fluorescent antibody titers to coronavirus. The indirect fluorescent antibody assay was validated by Western blots, which showed that all indirect fluorescent antibody-positive cheetah sera detected both domestic cat...

Abstract Although cheetahs Acinonyx jubatus were once widespread in the Horn of Africa, their presence Somaliland has not been confirmed since 2010, and they have presumed extirpated recent years. During 2021–2022 Cheetah Conservation Fund Ministry Environment Climate Change carried out two rapid surveys Awdal region western to investigate status cheetah this area. The team collected socio-ecol...

Abstract In guilds, such as the large predators, species compete over multiple resources that are both consumable and non-consumable. The niche complementary hypothesis states competitors can overlap in resource use if there is low for at least one shared resource. Africa, cheetah, Acinonyx jubatus , with other carnivores across space, time prey known to be subordinate; however, rarely has enti...

The purpose of this paper is to contribute to the debate on the seemingly dichotomy between structure and chaos in the innovation literature. The paper illustrates how organizations simultaneously use rigid plans and remain flexible, by deliberate but unplanned initiations of small temporary teams in order to solve non-predicted problems. This phenomenon is labeled " cheetah teams ". Anchored i...

Re-introduction programs rely on reproductively sound individuals and high offspring survival once captively bred species are released into their natural habitat. Some species involved in captive breeding programs reproduce poorly: one prominent example is the cheetah (Acinonyx jubatus). Here we use the cheetah as a case study to test predictions from all current hypotheses explaining this phen...

Hunting cheetah reportedly store metabolic heat during the chase and abandon chases because they overheat. Using biologging to remotely measure the body temperature (every minute) and locomotor activity (every 5 min) of four free-living cheetah, hunting spontaneously, we found that cheetah abandoned hunts, but not because they overheated. Body temperature averaged 38.4°C when the chase was term...

A juvenile cheetah (Acinonyx jubatus) died with rapidly progressive pyrexia, tachypnea, abdominal effusion, and hepatomegaly. Postmortem examination revealed lesions consistent with acute disseminated infection with Toxoplasma gondii. The presence of this organism was confirmed in multiple organs by immunohistochemistry and polymerase chain reaction. To the best of our knowledge, we propose thi...

This project aims at implementing a close-to-reality model of the recently developed Cheetah robot [1] in Webots [2], a commercial mobile robot simulation software developed by Cyberbotics Ltd. Furthermore, a pre-developed CPG [3] will be applied to the robot to determine feasible gaits and their optimal parameters for the Cheetah robot. Special interest lies in the characterization of the usef...

There are increasing numbers of private (nonprofit and for-profit) centers that carry out conservation research and education in locations of environmental concern. Such centers generate revenue streams that directly support conservation programs and also sustain surrounding human communities. This paper assesses the size of the centers' economic impacts. We conducted separate studies of the ec...
