Auditory system comparisons between sand cats and other felid species : acoustic input admittance of ears and auditory brainstem responses
… specimens, including sand cats and five other felid species. Sand cats have lower mean thresholds at frequencies between 0.25 and 5 kHz by 6-9 dB than other felid species measured. However, the mean power absorption does not differ significantly. The results are consistent with the hypothesis …

Non-invasive assessment of stress hormones, parasites, and diet, using scat of five felid species in Belize, Central America
Many Neotropical felid species, such as jaguars, are threatened with extinction due to habitat fragmentation and/or human persecution. Human activities around protected areas in Belize, Central America, are increasing and so are levels of human-felid conflict. Potential consequences of this …

Repurposing the human immunodeficiency virus (HIV) integrase inhibitor raltegravir for the treatment of felid alphaherpesvirus 1 (FHV-1) ocular infection
… 1 (HHV-1), canid alphaherpesvirus (CHV-1), and felid alphaherpesvirus 1 (FHV-1), respectively. Rapid and effective antiviral therapy is of the utmost importance to control infection in order to preserve the vision of infected people or animals. However, current treatment options are suboptimal, …

Detection of Babesia species in domestic and wild Southern African felids by means of DNA probes
… the two best characterised Babesia species in felids. These two parasites are morphologically similar when examined under a light microscope, but are serologically and genetically distinct. In this study the prevalence of these two Babesia species in various wild and domestic felid species was …

Investigation of spermatozoal metabolism and substrate utilization in domestic and non-domestic felids
… all cells are further impaired. More than 90% of felid species are affected by this condition, and it is prevalent among humans. Previous research suggested that impaired sperm metabolism in cheetahs – a ubiquitously teratospermic species – contributes to their poor cryosurvival and function, but …

Associations between MHC class I variation and blood pathogen prevalence in caracal
… a number of MHC genes has been described in many felid species, the relationship between MHC diversity and pathogen prevalence within wild felid populations has rarely been examined previously. Because many wild felids are highly sensitive to the effects of anthropogenic-induced environmental …

Mammal and bird trackways in the Miocene Horse Spring Formation, Clark County, Nevada
… canid tracks (Canipeda sp.) and a possible felid track ( Felipeda? sp.). One canid trackway records a c-shaped pattern, which is apparently the fist documentation of a rotary gallop gait in Miocene canids. Five types of bird tracks, four of which are previously undescribed, also occur. They …

Predatory sequence learning for synthetic characters
… the development of predatory behavior in certain felid and canid species. We describe the implementation of a few of these principles as an extension to a popular algorithm for learning in autonomous systems called hierarchical Q-learning. In this new approach, the agent starts out with only one …

Factors affecting replication and cross-species transmission of feline immunodeficiency virus
… immunodeficiency virus (FIV) infects diverse felid species including the African lion, where infection has likely been endemic since at least the late Pleistocene, and the domestic cat, a more recent host. For domestic cat strains of FIV (FIV-Fca), entry is mediated by host proteins CD134 and …

Estimation of population density and investigation of socio-spatial organization of ocelots (Leopardus pardalis) from comparison and integration of two noninvasive methods
… 2013). Among the 37 extant species in the family Felidae, 26 are listed as endangered, near threatened, or vulnerable, and over 86% have population numbers that are either decreasing or unknown (IUCN Red List 2011.2). The majority of felid species are secretive and solitary (Nowell and Jackson …

Ecology and restoration of Sumatran tigers in forest and plantation landscapes
… possible inter-specific interactions among wild felids, including tigers and smaller cats, based on data collected using systematic camera trapping in combination with information on their natural history. I found that despite overlap in resource needs of the five felid species, each appears …

Priming with Oral Progestin Before Ovulation Induction Facilitates Ovarian Function in the Cat (Felis catus)
… insemination (AI) has been developed in multiple felid species as a tool for retaining gene diversity in threatened or endangered populations. Yet, pregnancy success remains low (< 5%) following AI in most felids, particularly in species that spontaneously ovulate. This failure has been attributed …

Nutritional and Health Consequences of Feeding Diets of Varied Macronutrient Composition and Subjected to Select Processing Conditions in Domestic and Wild Felids
… or maintaining domestic and captive exotic felids through nutritional intervention. Five studies were performed to address two primary research objectives: (1) to determine changes in macronutrient digestibilities and fecal fermentative end-products of raw and extruded diets fed to domestic …

Metabolism and cryo-sensitivity of domestic cat (Felis catus) and cheetah (Acinonyx jubatus) spermatozoa
… abnormal spermatozoa) is prevalent among felids facing extinction risk, including the cheetah. This trait also occurs in certain domestic cat populations, providing a valuable research model. Multiple components of sperm function are disrupted in teratospermic cats, and even structurally …

A multiscale analysis and quantification of human impacts on Sumatran tiger (Panthera tigris sumatrae) habitat in Riau, Sumatra
… of human presence within Rimbang Baling on felid-prey relationships. I predict that by 2050, over 60% of natural forest in Riau will be lost, and all protected areas only confer low levels of protection. I determined that Tesso Nilo National Park has nearly 2500 km of roads within it and no …

Immunogenetics of free-ranging felids on Namibian farmlands
… (Panthera pardus) on Namibian farmlands. Both felid species are sympatric thus subject to similar pathogenic pressures but differ in their evolutionary and demographic histories. The main aims were to investigate 1) the extent and patterns of MHC variation at the population level in both …

Mammalian carnivores as bioindicators to evaluate the exposure and bioaccumulation of organic contaminants in terrestrial ecosystems
… of halogenated flame retardants in a wild felid in North America, and also the first report of PBDE accumulation in North American raccoons. The wide detection of Dechloranes, HBCD and TBCT in bobcats suggests a broad exposure of these alternative flame retardants in terrestrial apex …

Factors influencing cheetah (Acinonyx jubatus) distribution in Kafue National Park, Zambia
… among the most threatened species within the Felid family, cheetah are data deficient throughout much of their known range, including within protected areas of Zambia, a potential stronghold for the species. In this study, existing camera trap data collected between 2018 and 2023, were used to …

Habitat selection and spatial personalities of Belizean white-tailed deer
… deer (Odocoileus virginianus nemoralis)-felid (family Felidae) system in northwestern Belize to study their habitat selection and spatial personality. We live-captured and GPS-collared 13 white-tailed deer to obtain fine-scale movement data (2-hour fix rate). We combined GPS collar data …
