Estimating spotted hyaena (Crocuta crocuta) population density using camera trap data in a spatially-explicit capture-recapture framework
… for species that are rare and have large ranges. Camera trap surveys provide a non-invasive, inexpensive and effective method for obtaining population level data on wildlife species. Provided that species can be individually identified, a photographic capture-recapture framework can be used to …

From big spots to little spots: Influence of camera trap deployment on spatial capture-recapture estimates of servals (Leptailurus serval) in Ithala Game Reserve
… are frequently recorded as by-catch in camera trap surveys designed for larger carnivores which offers a unique opportunity to explore the viability of using these 'bi-catch' data for the determination of population estimates of cryptic carnivores. Spatial capture-recapture models are …

The density of leopards in a mixed-use landscape in the Western Cape, South Africa
… explicit capture-recapture (SECR) models on camera trap data to estimate how leopard density varies across a mixed-use landscape of protected areas, farmland, and urban areas in the Overberg region of the Western Cape, South Africa. Data were derived from 86 paired camera stations, which …

Species distribution, abundance and conservation in Nakai-nam Theun National Protected Area, Central-Eastern Laos: Implications for future local wildlife conservation project
… primate species sighted. In addition, I used the camera-trap database of 2006 management staff. Using modelling softwares (MAXENT, ENFA, DISTANCE) to provide baseline predictions, I analysed both my transect survey and the camera-‐trap survey data to assess the current status and distribution of …

Comparing fine-scale temporal environmental DNA (eDNA) sampling to camera trapping for detecting mammalian carnivores
… semi-aquatic mammals and compared favourably to camera trap results. However, carnivores are one of the more problematic groups regarding eDNA detections. In this study, the validity of semi-aquatic and terrestrial mammalian detection via eDNA was investigated within the north-eastern region of …

Mesocarnivores in Protected Areas: ecological and anthropogenic determinants of habitat use in northern Kwa-Zulu Natal, South Africa
… in mesocarnivore species richness within PAs. Camera trap surveys were conducted as part of Panthera’s 2015 national leopard monitoring programme in seven PAs across northern KwaZulu-Natal (KZN), South Africa. Using a multi-species extension of the Royle-Nichols occupancy model, my study …

Ecology of Tigers in Churia Habitat and a Non-Invasive Genetic Approach to Tiger Conservation in Terai Arc, Nepal
… and northwest India. I used a combination of camera-trapping techniques, which have been a popular and robust method for monitoring tiger populations across the landscape, combined with a noninvasive genetic approach to gain information on tigers, thus adding new information relevant to global …

Monitoring and Conserving Wildlife Communities across Northern Botswana
… these objectives, I completed a multi-year camera trap survey in a 1,154-km2 study area and analyzed the data using occupancy models (single and multi- species) and spatially explicit capture-recapture models. Estimates of species richness ranged from 8 to 27 unique species, species had a …

Effects of Canopy Cover and Impervious Surface Cover on Occurrence of Coyotes (Canis latrans) and Gray Foxes (Urocyon cinereoargenteus) throughout the United States
… these species. I obtained data from 9,010 camera trap locations grouped into two spatial scales. At the local level, I had 3,920 groups, and at the landscape level, I had 280 groups. I obtained percent canopy cover and impervious surface cover data from the National Land Cover Database. In …

Using Minimally Invasive Sampling Methods to Evaluate Polar Bear (Ursus maritimus) Visitation in Response to Environmental and Anthropogenic Stimuli
… this project were collected via a combination of camera trap surveys, evaluation of sea ice charts, and human use observations in the western Hudson Bay region. Using mixed effects logistic regressions, generalized linear models, and negative binomial regressions, I validated camera trap efficacy …

Quantifying Ungulate-Rangeland Interactions: From Monitoring Free-Roaming Horse Condition to Vegetation Response Following Herbivore Exclusion
… free-roaming horse body-condition scores from camera-trap imagery, comparing observer and veterinarian assessments to correct qualitative bias. The second analyzes a seventeen-year record of herbivory removal in a winterfat-dominated community in southeast Oregon, modeling long-term vegetation …

Exploring the causes of and mitigation options for human-predator conflict on game ranches in Botswana: How is coexistence possible?
… farmland was 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 …

Zooming in on human-wildlife coexistence: primate community responses in a shared agroforest landscape in Guinea-Bissau
… I integrate data from arboreal and terrestrial camera traps with habitat surveys, remote sensing and interviews with local people. For the first part of this thesis I use arboreal and terrestrial camera trap occupancy modelling across the landscape to investigate patterns of occurrence of seven …

Factors influencing cheetah (Acinonyx jubatus) distribution in Kafue National Park, Zambia
… for the species. In this study, existing camera trap data collected between 2018 and 2023, were used to assess cheetah occupancy estimates within Kafue National Park. These camera trap surveys were designed and run by the NGO Panthera Wildcat Conservation, in collaboration with Department …

Using Bayesian Hierarchical Models to Study the Spatial and Temporal Distribution of Mammals in Serengeti National Park
In this thesis, I work with camera trap data from the Snapshot Serengeti project in Serengeti National Park in Tanzania Africa. This data consists of the time and location where species were observed during the year 2012. Occupancy models are used to analyze this type of data, but they require …

Space Use and Survival of White-Tailed Deer in a Disturbance-Driven System Containing a Restored Apex Predator
… survival of deer, I analyzed GPS telemetry and camera trap data, highlighting the factors influencing deer space use across hydrological and biological seasons, and connected behavioral data captured on camera traps to female deer survival. Space use is primarily a function of intrinsic sex …
