Competition and coexistence in a small carnivore guild.

The potential for strong competition among small sympatric carnivores results in a need for coexistence strategies whereby competitors partition along spatial, temporal and dietary axes as a means to reduce ecological overlaps. We determined spatial and temporal partitioning patterns of a guild of small African carnivores: the African wildcat Felis silvestris lybica, grey mongoose Galerella pulverulenta, small-spotted genet Genetta genetta, striped polecat Ictonyx striatus, and the yellow mongoose Cynictis penicillata. We quantified the degree of spatial and temporal co-occurrence of the small carnivores using camera trap data over a year-long period. Carnivores separated into two temporal groups: nocturnal species (wildcat, polecat and genet) and diurnal species (mongooses). In addition, carnivores within the same temporal group had strong patterns of reduced spatial co-occurrence. The smaller bodied carnivores showed lower co-occurrence with the larger bodied African wildcat than expected by chance, supporting the idea of dominant competitor avoidance. Thus, small carnivores likely minimise competitive interactions through spatio-temporal habitat partitioning.

Interspecific responses of wild African carnivores to odour of 3-mercapto-3-methylbutanol, a component of wildcat and leopard urine

The scent of 3-mercapto-3-methylbutanol (3-M-3-MB), a volatile component of leopard (Panthera pardus) and domestic cat (Felis silvestris catus) urine, released at about 10 ng/s from slow-release dispensers, elicited scent-marking from African civet (Civettictis civetta), small-spotted genet (Genetta genetta) and slender mongoose (Galerella sanguinea), as well as African wildcat (F. s. cafra). A female leopard was apparently repelled by the scent. The scent-marking and scent-rubbing by species other than African wildcats and leopards were unexpected and have important implications for the design of studies to investigate chemical communication between wild mammals and the use of camera traps to estimate animal numbers.

The effect of space on behaviour in large groups of domestic cats kept indoors

The domestic cat (Felis silvestris catus) originates from the solitary living African wildcat (Felis silvestris lybica). However, through domestication, the domestic cat has become more social towards conspecifics and group housing of cats is common, for example in cat shelters in some countries. In Sweden the animal welfare legislation allows the keeping of up to 15 adult cats in the same room. However, keeping several cats in a small area may increase the level of conflicts between the cats and the social stress. In this study we examined the social and spatial behaviour in large groups of cats, as well as stress related body postures (using the Cat-Stress-Score) and if there were any changes within a stable group of 15 cats kept at different floor areas (1m2, 2m2 and 4m2 per cat). Cats in the study were collected as groups from two shelters and housed in a research facility. Cats from different shelters and groups were never mixed. Cats performed more solitary play (p=0.0016) and moved more between different resources (p=0.03) in the largest floor area. Based on our results we conclude that increasing the area for group housed cats promote more play and general activity. Play can be an indicator of positive welfare for the cats.

European wildcat populations are subdivided into five main biogeographic groups: consequences of Pleistocene climate changes or recent anthropogenic fragmentation?

Extant populations of the European wildcat are fragmented across the continent, the likely consequence of recent extirpations due to habitat loss and over-hunting. However, their underlying phylogeographic history has never been reconstructed. For testing the hypothesis that the European wildcat survived the Ice Age fragmented in Mediterranean refuges, we assayed the genetic variation at 31 microsatellites in 668 presumptive European wildcats sampled in 15 European countries. Moreover, to evaluate the extent of subspecies/population divergence and identify eventual wild×domestic cat hybrids, we genotyped 26 African wildcats from Sardinia and North Africa and 294 random-bred domestic cats. Results of multivariate analyses and Bayesian clustering confirmed that the European wild and the domestic cats (plus the African wildcats) belong to two well-differentiated clusters (average Ф ST=0.159, r st=0.392, P>0.001; Analysis of molecular variance [AMOVA]). We identified from c. 5% to 10% cryptic hybrids in southern and central European populations. In contrast, wild-living cats in Hungary and Scotland showed deep signatures of genetic admixture and introgression with domestic cats. The European wildcats are subdivided into five main genetic clusters (average Ф ST=0.103, r st=0.143, P>0.001; AMOVA) corresponding to five biogeographic groups, respectively, distributed in the Iberian Peninsula, central Europe, central Germany, Italian Peninsula and the island of Sicily, and in north-eastern Italy and northern Balkan regions (Dinaric Alps). Approximate Bayesian Computation simulations supported late Pleistocene-early Holocene population splittings (from c. 60k to 10kyears ago), contemporary to the last Ice Age climatic changes. These results provide evidences for wildcat Mediterranean refuges in southwestern Europe, but the evolution history of eastern wildcat populations remains to be clarified. Historical genetic subdivisions suggest conservation strategies aimed at enhancing gene flow through the restoration of ecological corridors within each biogeographic units. Concomitantly, the risk of hybridization with free-ranging domestic cats along corridor edges should be carefully monitored.

Some Nocturnal and Crepuscular Mammals of Kakamega Forest: Photographic Evidence

Kakamega Forest is a small remnant of Guineo-Congolian rainforest in Kenya. Along with direct observation, we used an automatic camera to sample the nocturnal and crepuscular mammalian fauna within 1.5 km of the Kakamega Forest Station near Isecheno. We detected 11 indigenous species belonging to 10 genera, as well as domestic cats and dogs. We directly observed pottos and African palm civets. Additionally, we photographed giant pouched rats, African civets, white-tailed mongooses, a marsh mongoose, a tree pangolin, servaline genets, blotched genets, side-striped jackals, and what appears to be an African wildcat. We found both whitetailed and black-tailed morphs of the white-tailed mongooses. Similarly, we recorded side-striped jackals with and without white-tipped tails. Our findings offer insight about the seldom studied nocturnal and crepuscular mammals of Kakamega Forest, including which species are persisting there, their various morphs, and some bait preferences, thus adding to and reaffirming previous reports.

Genetic analysis shows low levels of hybridization between African wildcats (Felis silvestris lybica) and domestic cats (F.s.catus) in South Africa.

Hybridization between domestic and wild animals is a major concern for biodiversity conservation, and as habitats become increasingly fragmented, conserving biodiversity at all levels, including genetic, becomes increasingly important. Except for tropical forests and true deserts, African wildcats occur across the African continent; however, almost no work has been carried out to assess its genetic status and extent of hybridization with domestic cats. For example, in South Africa it has been argued that the long-term viability of maintaining pure wildcat populations lies in large protected areas only, isolated from human populations. Two of the largest protected areas in Africa, the Kgalagadi Transfrontier and Kruger National Parks, as well as the size of South Africa and range of landscape uses, provide a model situation to assess how habitat fragmentation and heterogeneity influences the genetic purity of African wildcats. Using population genetic and home range data, we examined the genetic purity of African wildcats and their suspected hybrids across South Africa, including areas within and outside of protected areas. Overall, we found African wildcat populations to be genetically relatively pure, but instances of hybridization and a significant relationship between the genetic distinctiveness (purity) of wildcats and human population pressure were evident. The genetically purest African wildcats were found in the Kgalagadi Transfrontier Park, while samples from around Kruger National Park showed cause for concern, especially combined with the substantial human population density along the park's boundary. While African wildcat populations in South Africa generally appear to be genetically pure, with low levels of hybridization, our genetic data do suggest that protected areas may play an important role in maintaining genetic purity by reducing the likelihood of contact with domestic cats. We suggest that approaches such as corridors between protected areas are unlikely to remain effective for wildcat conservation, as the proximity to human settlements around these areas is projected to increase the wild/domestic animal interface. Thus, large, isolated protected areas will become increasingly important for wildcat conservation and efforts need to be made to prevent introduction of domestic cats into these areas.

Molecular detection of tick-borne pathogens in captive wild felids, Zimbabwe.

BackgroundThe populations of wild felids in Africa, of especially lions (Panthera leo) and cheetahs (Acinonyx jubatus), are declining and the species are classified as vulnerable to extinction by the International Union for Conservation of Nature. As infections with tick-borne pathogens (TBP) can become more of a problem in wild felids, there are relatively few studies on TBP in wild felids in Africa and on how these infections might influence population numbers.MethodsTo gain further knowledge on TBP in captive wild felids in Southern Africa, we collected whole blood from captive lions, Southern African wildcats, cheetahs and servals in Zimbabwe for PCRs against the 18S rRNA gene of the piroplasmids (Babesia, Theileria, Cytauxzoon) and Hepatozoon spp., and the 16S rRNA gene of Ehrlichia and Anaplasma spp.ResultsOverall, 78% of the lions (67/86) and all the Southern African wildcats (6/6), cheetahs (4/4) and servals (2/2) had evidence of infection with at least one organism. The organisms most commonly detected in the lions were B. leo (59%; 51/86), B. vogeli (12%; 10/86) and H. felis (11%; 9/86) while all the Southern African wildcats and servals were positive for B. vogeli and all the cheetahs were positive for B. leo. Mixed infections were found in 22% (15/67) of the PCR positive lions, most commonly B. leo and H. felis (27%; 4/15), and in 1 (50%) of the servals (B. vogeli and A. phagocytophilum). Two lions were infected with three TBP, mainly B. leo, H. canis and T. parva, and B. leo, A. phagocytophilum and T. sinensis. Mixed infections with B. vogeli and A. phagocytophilum were seen in a serval and a Southern African wildcat. Other TBP were detected at a low prevalence (≤2%) in lions, mainly H. canis, T. sinensis, T. parva, C. manul, E. canis, and E. canis-like and B. odocoilei-like organisms.ConclusionsInfections with tick-borne agents are common in captive wild felids in Zimbabwe.

More evidence for cat taming at the Predynastic elite cemetery of Hierakonpolis (Upper Egypt)

Continued excavations at the Predynastic elite cemetery HK6 at Hierakonpolis have yielded new evidence for the cultural control of cats during the Naqada IC-IIB period (c. 3800–3600 BC). In the same burial ground where evidence was previously found for the keeping of jungle cat (Felis chaus), a small pit was discovered containing six cats. The animals that were buried simultaneously, are a male and a female, and four kittens belonging to two different litters. The long bone measurements of the adult individuals clearly fall in the range of Felis silvestris and outside those of F. chaus and F. margarita. Comparison of the measurements – through the log-ratio technique – with data from the literature, as well as morphological characteristics of the mandible, suggest that the animals are domestic. It is argued that these results should be used with caution, since the criteria established to distinguish wild and domestic cat in European sites may reflect differences at the subspecies level (wild Felis silvestris silvestris versus the domestic form derived from Felis silvestris lybica). In northern Africa only F. s. lybica (wild or domestic) occurs, thus the established criteria may not be adequate when applied to Egyptian material. However, possible circumstantial evidence for the cultural control of the cats buried at Hierakonpolis is provided by their ages at death which indicate a deviation from the birth pattern reported in Egyptian wild cats.

Infections with tick-borne agents are common in captive wild felids in Zimbabwe.

Apparent total tract macronutrient and energy digestibility of 1- to- 3-day-old whole chicks, adult ground chicken, and extruded and canned chicken-based diets in African wildcats (Felis silvestris lybica)

Our objectives were to evaluate the composition of whole 1- to- 3-day-old chicks (Whole), ground adult chicken (Ground), chicken-based canned diet (Canned), and chicken-based extruded diet (Extruded); and evaluate apparent total tract energy and macronutrient digestibility of these diets by four captive African wildcats (Felis silvestrus lybica) utilizing a Latin Square design. We analyzed diets for macronutrient and mineral (Ca, P, K, Na, Mg, Fe, Cu, Mn, Zn, and S) composition, and screened for potentially pathogenic bacteria. Canned and Extruded diets tested negative for all microbes and met macronutrient and mineral recommendations for domestic cat foods [AAFCO (2012). Official publication. Oxford, IN: AAFCO]. Whole prey diets (Ground and Whole) met macronutrient requirements for domestic cats; however, they were below recommendations in some minerals [Mn, Cu, K, and Na; AAFCO (2012). Official publication. Oxford, IN: AAFCO], and tested positive for potentially pathogenic microorganisms (Salmonella, E. coli spp.). For all diets, apparent total tract organic matter digestibility was high (>85%). Organic matter digestibility was higher (P ≤ 0.05) for cats fed Ground (94%) compared to those fed Canned, Extruded, or Whole (87, 86, and 85%, respectively). Apparent total tract crude protein digestibility was lower than expected (i.e., <85%) for cats fed Extruded (81%) and fat digestibility was lower than expected (i.e., <90%) for cats fed Whole (82%). Cats fed whole prey items tested herein adequately maintained BW short-term; however, long-term studies are needed. These data indicate that there may be a need to monitor whole prey composition and when necessary, adjust the diet to account for potential deficiencies.

Evaluation of four raw meat diets using domestic cats, captive exotic felids, and cecectomized roosters

Our objective was to evaluate raw meat diets for captive exotic and domestic carnivores containing traditional and alternative raw meat sources, specifically, beef trimmings, bison trimmings, elk muscle meat, and horse trimmings. We aimed to examine diet composition and protein quality; apparent total tract energy and macronutrient digestibility in domestic cats, African wildcats, jaguars, and Malayan tigers; and ME and fecal fermentative end-products in domestic cats. Because of variation in the meat sources, dietary proximate, AA, and long-chain fatty acid composition were variable. Our analyses indicated that all diets had essential fatty acid deficiencies, and the elk diet (i.e., trimmed muscle meat) was deficient in total fat. Standardized AA digestibilities measured using the cecectomized rooster assay were high (>87%). Using the NRC minimum requirements for the growth of kittens, the first limiting AA of all diets was the combined requirement of Met and Cys (AA score: 81 to 95; protein digestibility corrected AA score: 75 to 90). All diets were highly digestible (88 to 89% OM digestibility). There was no effect of diet or felid species on DM (85 to 87%), OM, and GE (90 to 91%) digestibilities. Apparent CP digestibility was greater (P≤0.05) in cats fed elk (97%) compared with those fed bison (96%), and greater (P≤0.05) in wildcats (97%) and domestic cats (97%) compared with tigers (95%). The diet and species interaction (P≤0.05) was observed for apparent fat digestibility. In domestic cats, the fresh fecal pH and proportions of acetate and butyrate were altered (P≤0.05) due to diet. Diet also affected (P≤0.05) fresh fecal concentrations of total branched-chain fatty acids, valerate, and Lactobacillus genus. In conclusion, although the raw meat diets were highly digestible, because of variation in raw meat sources the nutrient composition of the diets was variable. Thus, compositional analysis of raw meat sources is necessary for proper diet formulation. The types of meat commonly used in raw meat diets may be deficient in total fat (trimmed muscle meat) and essential fatty acids (trimmings and muscle meats). Additionally, differences in raw meat source nutrient composition and digestibility affect the beneficial and putrefactive fermentative end-products found in feces.

26 PRODUCTION OF CLONED KOREAN RACCOON (NYCTEREUTES PROCYONOIDES KOREENSIS) EMBRYOS BY INTERSPECIES SOMATIC CELL NUCLEAR TRANSFER USING ENUCLEATED PIG OOCYTES

Interspecies somatic cell nuclear transfer (iSCNT) could be a useful method for embryo research of wildlife animals or endangered species. Because it is hard to obtain the oocytes or embryos of wildlife animals, its embryo research is not progressing well. Therefore, iSCNT is one of the alternative ways for wildlife animal embryo research and conservation of their genetic source. Until now, iSCNT has been applied to conservation of wildlife animals including guar, mouflon, banteng and African wildcat. The domestic pig oocytes have been used for iSCNT of other species such as tiger, sheep and dog and they successfully developed to the blastocyst stage. According to this concept, we performed wild-captured Korean raccoon (Nyctereutes procyonoides koreensis) iSCNT using porcine oocytes matured in vitro. Raccoon fibroblasts from ear skin samples of male raccoon were used as donor cells in 3 to 5 passages. The donor cells were cultured in DMEM supplemented with 15% FBS. Enucleated porcine oocytes were fused with raccoon fibroblasts by electrofusion. The iSCNT embryos were cultured in PZM-3 at 39°C for 7 days in an atmosphere of 5% CO2 and 5% O2. A total of 158 iSCNT embryos were cultured. More than 77% of the raccoon somatic cells successfully fused with the porcine oocytes; 68.5% of the iSCNT raccoon embryos developed to the 2- to 8-cell stage at Day 2 (1-cell: 9.7%, 2-cell: 14.4%, 4-cell: 34.1%, 6-cell: 12.7%, 8-cell: 7.3%, fragmented: 21.8%). This is similar to porcine SCNT results that 62.5% of the SCNT porcine embryos developed (1-cell: 8.0%, 2-cell: 4.2%, 4-cell: 23.6%, 6-cell: 13.6%, 8-cell: 23.8%, fragmented: 26.8%). But no embryos were further developed to blastocyst stage at Day 7 in iSCNT. In fragmentation evaluation in iSCNT embryos using by Hoechst stain at Day 2, two-cell stage embryos and four-cell stage embryos showed the normal numbers of nucleus. However, 6-cell stage embryos showed 4 to 5 nuclei and 8-cell stage embryos also showed 5 to 6 nuclei. Almost iSCNT embryos showed the developmental block at 4-cell stage embryos. This result was probably caused by an incomplete reprogrammed raccoon cell after iSCNT. Therefore, we treated with trichostatin A (TSA), a histone deacetylase inhibitor that has been used to enhance nuclear reprogramming following SCNT. Ninety-seven iSCNT raccoon-pig embryos were treated with 5 nM TSA during 15 h before being cultured in PZM-3. The TSA-treated iSCNT embryos showed similar developmental status to non-treated embryos (1-cell: 13.5%, 2-cell: 12.5%, 4-cell: 35.0%, 6-cell: 10.1%, 8-cell: 6.3%, fragmented: 22.5%). No embryos were further developed to blastocyst stage at day 7. Our results showed that 4-cell stage embryos of raccoon-porcine iSCNT embryos may be produced by iSCNT methods, but they were unable to support complete reprogramming of raccoon-porcine iSCNT embryos.

Influence of feeding raw or extruded feline diets on nutrient digestibility and nitrogen metabolism of African wildcats (Felis lybica)

The African wildcat is one of the closest ancestors to the domestic cat and is believed to have similar nutrient requirements, but research is lacking. The objective of this study was to determine the effects of feeding a high-protein extruded kibble diet vs. a raw meat diet on nutrient digestibility, nitrogen metabolism, and blood metabolite concentrations in African wildcats. Five wildcats were randomized onto either a high-protein (>50% crude protein) extruded kibble diet or a raw meat diet. The study was executed as a crossover design, with 21-d periods, consisting of a 16-d adaptation phase followed by a 4-d total fecal and urine collection phase. Cats were housed individually in metabolism cages and fed to maintain body weight (BW). A fresh fecal sample was collected for short-chain fatty acid (SCFA) and branched-chain fatty acid (BCFA) analyses. Blood was analyzed for serum chemistry and leptin concentration. Food intake (as is) did not differ (P>0.05) between diets. Food intake and fecal output (g/d DMB) were greater (P<0.05) when cats consumed the kibble diet. Protein digestibility was higher (P<0.05) when cats were fed the raw meat diet vs. the kibble diet. Nitrogen intake was greater (P<0.05) when cats consumed the kibble diet, and more (P<0.05) nitrogen was present in the feces; however, the percentage of nitrogen retained and nitrogen balance did not differ (P>0.05). Fecal scores, ammonia, SCFA, and BCFA concentrations did not differ (P>0.05) between diets. Fecal butyrate molar ratio was higher (P<0.01) when cats consumed the kibble diet. Blood analyses demonstrated few differences between diets, but alanine aminotransferase activity and bicarbonate were higher (P<0.05) when cats consumed the commercial raw meat diet. Owing to lack of differences, these data indicate that African wildcats can readily utilize a high protein extruded kibble diet, and may be able to replace a commercial raw meat diet.

Parasites of domestic and wild animals in South Africa. XLVIII . Ticks (Acari: Ixodidae) infesting domestic cats and wild felids in southern Africa

Ticks collected from domestic cats (Felis catus), cheetahs (Acinonyx jubatus),caracals (Caracal caracal), African wild cats (Felis lybica), black-footed cats (Felis nigripes), a serval (Leptailurus serval), lions(Panthera leo), and leopards (Panthera pardus) were identified and counted. Thirteen species of ixodid ticks and one argasid tick were identified from domestic cats and 17 species of ixodid ticks from wild felids. The domestic cats and wild felids harboured 11 ixodid species in common. The adults of Haemaphysalis elliptica, the most abundant tick species infesting cats and wild felids, were most numerous on a domestic cat in late winter and in mid-summer, during 2 consecutive years. The recorded geographic distribution of the recently described Haemaphysalis colesbergensis, a parasite of cats and caracals, was extended by 2 new locality records in the Northern Cape Province, South Africa.

The feeding habits of the Southern African wildcat, a facultative trophic specialist, in the southern Kalahari (Kgalagadi Transfrontier Park, South Africa/Botswana)

This research was supported by the Endangered Wildlife Trust's Carnivore Conservation Group (South Africa), the Elizabeth Wakemen Henderson Charitable Foundation, the Mammal Research Institute and the Molecular Ecology and Evolution Program (Department of Genetics) at the University of Pretoria, the National Research Foundation (South Africa), the Kaplan Awards Program from Wildlife Conservation Society and the Skukuza Marathon Club.

Techniques used in the study of African wildcat, &lt;i&gt;Felis silvestris cafra&lt;/i&gt;, in the Kgalagadi Transfrontier Park (South Africa/Botswana)

The techniques used for the capture, marking and habituation of African wildcats (Felis silvestris cafra) in the Kalahari are described and evaluated in this paper. African wildcats were captured, with either baited cage traps or chemical immobilisation through darting. Darting proved to be a more efficient and less stressful way of capturing cats. Very high frequency (VHF) radio collars fitted with activity monitors were especially effective in the open habitat of the Kalahari for locating and maintaining contact with cats; they also aided in determining if the cats were active or resting in dense vegetation. The habituation of individual cats to a 4×4 vehicle proved to be time consuming, but it provided a unique opportunity to investigate the feeding ecology and spatial organisation of cats through direct visual observations.Conservation implications: In describing and comparing the various methods of capture, handling and release of the African wildcats that we followed during our study in the southern Kalahari, we recommend the most efficient, least stressful method for researchers to follow – both in relation to time and energy, as well as in terms of the impact on the animals being studied.

Light whole genome sequence for SNP discovery across domestic cat breeds.

BackgroundThe domestic cat has offered enormous genomic potential in the veterinary description of over 250 hereditary disease models as well as the occurrence of several deadly feline viruses (feline leukemia virus -- FeLV, feline coronavirus -- FECV, feline immunodeficiency virus - FIV) that are homologues to human scourges (cancer, SARS, and AIDS respectively). However, to realize this bio-medical potential, a high density single nucleotide polymorphism (SNP) map is required in order to accomplish disease and phenotype association discovery.DescriptionTo remedy this, we generated 3,178,297 paired fosmid-end Sanger sequence reads from seven cats, and combined these data with the publicly available 2X cat whole genome sequence. All sequence reads were assembled together to form a 3X whole genome assembly allowing the discovery of over three million SNPs. To reduce potential false positive SNPs due to the low coverage assembly, a low upper-limit was placed on sequence coverage and a high lower-limit on the quality of the discrepant bases at a potential variant site. In all domestic cats of different breeds: female Abyssinian, female American shorthair, male Cornish Rex, female European Burmese, female Persian, female Siamese, a male Ragdoll and a female African wildcat were sequenced lightly. We report a total of 964 k common SNPs suitable for a domestic cat SNP genotyping array and an additional 900 k SNPs detected between African wildcat and domestic cats breeds. An empirical sampling of 94 discovered SNPs were tested in the sequenced cats resulting in a SNP validation rate of 99%.ConclusionsThese data provide a large collection of mapped feline SNPs across the cat genome that will allow for the development of SNP genotyping platforms for mapping feline diseases.

African Acrostics: A Word in Edgeways (review)

The poems are nimble and crafty, demonstrating that acrostics can actually be effective verse as well as technical achievements. Harley tucks in rhymes, alliteration, and poetic tropes and seasons her verse with a playful sensibility ("But/ Even so, I know/ A rhino when I / See one, and this is the time not/ To"), making them entertaining to read across as well as down, perhaps even out loud. The layout is actually on the young side for the poetry, following the big print/colored background/portrait photo format familiar from many early verse collections, but the photos, taken in Namibia's Etosha National Park, are vivid close-ups. Young wordsmiths will itch to try their hands at the verse form after reading this; it would also make a useful complement to Janeczko's A Kick in the Head (BCCB 4/05) in discussing poetic forms and structure. A concluding spread offers more information about acrostics, including advanced versions such as double and multiple acrostics; another spread offers natural-history notes on the featured animals, while a statement from the photographer gives some insight into Namibia.

Oral Examination and Radiographic Evaluation of the Dentition in Wild Cats from Namibia

Feline tooth resorption has been widely reported in domestic cats and sporadically described in other felidae. The goal of the present study was to determine the prevalence of tooth resorption and to report other dental problems in a population of wild felidae. Observations of dental disorders and anomalies were made in skulls from 73 wild felidae (cheetahs, leopards, caracals, African wildcats, and lions) originating from Namibia. In addition, radiographs were taken in 43 cases to determine signs of bone and root pathology. Radiographs showed varying stages of tooth resorption in 16.0% of the specimens. Other dental anomalies found included fused teeth, supernumerary roots, or missing teeth. The prevalence of dental resorption in wild felidae was lower than reported in the domestic cat.

Impact of Livestock Husbandry on Small‐ and Medium‐Sized Carnivores in Kalahari Savannah Rangelands

ABSTRACT We analyzed relative sensitivities of small‐ and medium‐sized carnivores to livestock husbandry (stocking rates and predator control) in Kalahari, South Africa, rangelands at a regional scale. We monitored small carnivores using track counts on 22 Kalahari farms across a land‐use gradient ranging from low to high stocking rates and also interviewed each farm manager to identify farmers' perception of small carnivores as potential predators for livestock. We recorded 12 species of small‐ and medium‐sized carnivores across 22 Kalahari farms. Stocking rate was the most important driving variable for local carnivore abundance. Abundance of all species was lowest on farms where stocking rate was high. Most farm managers perceived medium‐sized carnivores, in particular, African wildcat (Felis silvestris lybica), black‐backed jackal (Canis mesomelas), and caracal (Caracal caracal), as potential predators of livestock. Multiple regression analysis shows that black‐backed jackal, African wildcat, and caracal were negatively affected by predator control measures, whereas bat‐eared fox (Otocyon megalotis), cape fox (Vulpes chama), and small‐spotted genet (Genetta genetta) were positively affected. Our results show a need for expanding research and conservation activities toward small‐ and medium‐sized carnivores in southern African savannah rangelands. We, therefore, suggest developing a monitoring program combining passive tracking with indigenous knowledge of local Khoisan Bushmen to monitor carnivore populations, and we recommend additional predator removal experiments that manipulate predator densities.
