Exploring the causes of and mitigation options for human-predator conflict on game ranches in Botswana: How is coexistence possible?
… calculated using spoor and camera-trap surveys. Scat-analysis was used to determine the proportion of livestock and game-stock in the cheetah's diet, the species reported to cause the biggest economic losses on Botswana game ranches. Questionnaires to determine the direct costs, drivers and …

Wolf Predation: Where and How Wolves Kill Beavers, and Confronting the Biases in Scat-Based Diet Studies
… <p> Wolf diet is commonly estimated via scat analysis, and several studies have concluded that scat collection method can bias diet estimates. I tested whether different scat collection methods yield different diet estimates after accounting for other biases. I collected scats (2,406 …

Summer wolf diet in northwestern Montana
… be estimated from undigested remains of prey in scats or through stable isotope analysis (SIA) of wolf hair when distinct δ13C and δ15N values of potential diet sources are known. Our objectives were to compare diet analysis methods, to estimate intra-population diet variability, and to determine …

Influence of gypsy moth induced oak mortality on a black bear population
… data collected in SNP from 1982 - 1985. Scat analysis indicated that the current diet of SNP’s black bear population includes proportionally more soft mast in the fall and more soft mast and ants (Formicidae spp., P<0.0001) in the summer than did the preinfestation diet. Fewer acorns …

Monitoring Program and Assessment of Coyote Predation for Olympic Marmots
… marmot mortality. Through park-wide carnivore scat analysis I determined the spatial extent of coyote predation on Olympic marmots and the magnitude of coyote predation relative to other carnivore species. I used mtDNA analysis of scats to determine carnivore species and microsatellite markers …

Analysis of seasonal variation in dietary composition and behaviour of wild chacma baboons (Papio ursinus) in two habitats of different human influence around windhoek, central Namibia
… using a focal animal method. Forty-nine (49) scat samples were collected between the seasons, separated in the laboratory, weighed, and placed into four categories (fruits and seeds, roots, stems, and leaves, invertebrates, and others). Results showed that baboons consumed plant materials more …

Investigating the hidden costs of livestock guarding dogs and the diet of a sympatric predator in Namaqualand, South Africa
… hidden costs of their presence. This study used scat analysis to reconstruct the diet of livestock guarding dogs and local caracals (Caracal caracal) to better understand their impacts on biodiversity and livestock in Namaqualand, South Africa. For livestock guarding dogs, 187 scats revealed the …

Movement analysis for monitoring predation by large carnivores : lions in Kruger National Park
… direct continuous observation, stomach content analysis, carcass observations and scat analysis. Continual observations are widely considered the best approach to estimate large carnivore diets, with lions (Panthera leo) being no exception. Continual observation allows the recording of all prey …

Life on the edge: exploring the effects of urbanisation on the foraging ecology and ecotoxicology of caracals
… Town, South Africa. Through a combination of scat analysis (n = 654 scats) and prey remains located at 677 GPS clusters, I quantified dietary resource use of 26 collared individuals, as well as opportunistically sampled caracals. Using a range of gut transit times, I estimated whether scat at …

Assessing the effect of feather wear on carbon and nitrogen stable isotope ratios, and the use of stable isotopes to determine predator diets in the Namibian Islands marine protected area
… dietary analyses such as stomach content and scat analysis which provide short-term diet information. Here, I measured carbon and nitrogen SI ratios in several tissues of the marine top predators, and those of their potential prey species, to infer the marine food web for this region, and to …

Characteristics, determinants and management of farmer-predator conflict in a multi-use dryland system, South Africa
… and occupancy, notably predators. I then used scat analysis to compare the diet of jackal and caracal with those of conspecifics living in the PA to understand whether predators on farmland are targeting livestock or simply including them opportunistically in their diet. I also used Global …
