Leveraging Partial Identity Information in Spatial Capture-Recapture Studies with Applications to Remote Camera and Genetic Capture-Recapture Surveys
… identity models to the noninvasive methods of remote cameras for species that are difficult to identify from photographs and DNA from hair or scat samples. The ability of these novel models to improve parameter estimation and extend study design options are investigated and the methods are made …

Noninvasive tracking of jaguars (Panthera onca) and co-occurring Neotropical felids in Belize, Central America by genotyping feces and remote camera trapping
… 95% EtOH) suitable for long-term preservation at remote tropical sites. Additionally, we tested fecal DNA samples collected from four different scat locations (top, side, bottom, inside). DET buffer was the superior fecal DNA preservation method and collecting fecal DNA from side and top locations …

Patterns in Gray Wolf Pup Survival and Recruitment in Northern Minnesota
… counts and video observations from a large remote camera array to estimate annual wolf pup survival and recruitment and to evaluate intra-annual patterns in pup survival and recruitment within the Greater Voyageurs Ecosystem, MN, USA. Mean annual pup survival during 2019–2023 was 0.24, and …

Densities, habitat-use, and mesopredator release of the ocelot in Belize
… competition with jaguars and pumas. I conducted remote camera surveys and sampled habitat within four protected areas: three broadleaf sites and one pine forest site. I measured ocelot activity and habitat-use with respect to the activity of jaguars and pumas at one broadleaf site and one pine …

Extirpation Risk of the Endangered Golden Langur (<i>Trachypithecus geei</i>) Inside and Outside Biological Corridors, Langthel Sub-district, Trongsa, Central District Bhutan
… range for each group. Using a combination of remote camera trapping, sign survey method, and key informant interviews, I confirmed the presence of potential predators for golden langurs. I used qualitative risk analysis to analyze the probability and impact of six extirpation risks: 1) …

Estimating abundance, density, and occupancy of lion, leopard and serval in the Niokolo Koba National Park in Senegal
… Koba National Park, Senegal, West Africa, using remote camera surveys and both traditional (CR), spatially explicit capture-recapture (SECR) techniques for servals and leopards, and non-spatial (MR) and spatial mark resight (SMR) methods for lions. Lions selected optimal sites with both high tree …

Augmented Reality Navigation Interfaces Improve Human Performance In End-Effector Controlled Telerobotics
… observed when manual control is mediated through remote camera views, resulting in poor end-effector navigation quality and extended task completion times. This thesis explores the application of three-dimensional augmented reality (AR) interfaces specifically designed to improve human performance …

The reproductive biology of four geoflorous Protea species (Proteaceae)
… and their temporal patterns of activity using remote camera footage. Rodents were found to be the most frequent visitors to the flower heads of the study species. Floral morphology, nectar volume and sugar concentration of the study species conform to the general syndrome of non-flying mammal …

Keeping it cool: mammal responses to microclimatic variation in disturbed Indonesian lowland forest.
… terrestrial mammals using occurrence data from remote camera traps and fine-scale data of climate and habitat structure measured from the field. Next, I implement and test the performance of two freely available mechanistic models of microclimate, ‘NicheMapR’ and ‘microclimc’, and determine the …

An assessment of Quality Deer Management on a private hunt club in the Virginia Piedmont
… a new rocket net method to capture deer using a remote video system that was more efficient than traditional methods. I monitored 20 deer; 50% died due to hunting and 15% to natural mortality. The emigration rate for juvenile males was 46%, dispersal distance averaged 6.4 km. I used Home Range …

Red fox ecology and interactions with piping plovers on Fire Island, New York
… plovers on Fire Island, New York. We conducted remote camera surveys, scat and sign surveys, den monitoring, and GPS tracking of red foxes on the island in 2015–2018. We used these data to estimate red fox occupancy, reproduction, survival, and population density. We used GPS data to investigate …

Ecology of feral cats Felis catus and their prey in relation to shrubland fire regimes
… in resource use between cats and dingoes using remote camera surveys and dietary analysis of scats. Both carnivores were recorded in all four major habitat types: recently burnt shrublands (10 to 14 years since last fire), long unburnt shrublands (34 to ~49 years), very long unburnt shrublands …

Comparative abundance and ranging behaviour of brown hyaena (Parahyaena brunnea) inside and outside protected areas in South Africa
… are subject to different pressures. The use of remote camera traps demonstrated that the relative abundance of brown hyaena was four times lower in unprotected areas than in the protected areas. A significant finding was that mesopredators showed higher relative abundances in the unprotected …

The threat of terrestrial predators to mainland penguin colonies: searching for sustainable solutions
… intervention strategies at both colonies. Remote camera traps proved effective at early detection and identifying species responsible, while physical barriers were effective at reducing access to colonies. Capture and collaring of caracal on the Peninsula with follow-up monitoring of …
