PS68 – Study design considerations and recommendations when studying American black bears (Ursus americanus) via hair snares
Abigail Thiemkey, University of Maryland College Park Estimates of wildlife populations are foundational to management decision-making. Sound science enables wildlife managers to develop rules and regulations that inform harvest recommendations […]
PS69 – Population Density and Potential Sarcoptic Mange Transmission in American Black Bears: A Spatial Capture-Recapture Study in the Appalachian Mountains of Virginia
Madison Thurber, Virginia Tech Infectious diseases pose a significant threat to wildlife conservation by driving population declines, fragmentation, and local extinctions. These risks are intensifying as anthropogenic pressures alter ecosystems, […]
PS70 – Population resilience vs. increasing mortality: A multi-method demography of brown bear in the Western Carpathians
Nikola Tkáčová, Faculty of Science, Charles University Population status is often communicated as census size, but long-term persistence depends on evolutionary capacity and human-driven mortality. By integrating spatial demography with […]
PS61 – Age estimation based on DNA methylation levels in liver and muscle
Michito Shimozuru, Hokkaido University Age is an essential information for understanding the ecology and management of bears. Instead of traditional age estimation method by counting cementum annuli of the teeth, […]
PS65 – Climate-driven pulses of desert corridor by American black bears (Ursus americanus): a dynamic occupancy framework
Sydney Stephens, University of Trento Low-elevation shrublands of the red rock deserts in southeastern Utah have traditionally been treated as marginal, transitory habitat for forest-associated large mammals between “sky island” […]
PS17 – Validation of grizzly bear hair hormone profiles as a tool to monitor population demographics
Dario Fernandez-Bellon, fRI Research A common approach to monitoring bear populations is the use of non-invasive DNA sampling through hair snags to estimate population sizes. Although successful in acquiring population […]
OS27 – Quantifying Adaptive Potential for Ursus americanus and Ursus maritimus for the Global Biodiversity Framework
Emily Puckett, Alexander Kopatz American black bears (Ursus americanus) have faced numerous threats since colonization into North America (ca. 1500), including habitat loss, predator persecution, urbanization, and climate change. These […]
PS02 – Seeing the unseen: how camera trap placement, harvesting pressure and habitat features shape large mammal detection
Giulia Amato, University of Udine Camera trapping is a non-invasive method widely used to inventory and monitor wild species. It is mainly used to quantify and identify the presence of […]
PS07 – Would an interconnected system of critical conservation areas enhance long-term survival of a simulated Apennine brown bear metapopulation?
Livia Chavko, Sapienza University of Rome The Apennine brown bear (Ursus arctos marsicanus) is a relict, long isolated, and highly inbred population facing a higher extinction risk over the next […]
OR20 – History of polar bear (Ursus maritimus) exploitation in Canada: hunt types and periods, data sources, and research needs for a comprehensive assessment of historical population trends
Polar bear (Ursus maritimus) hunting in Canada has a long history, spanning thousands of years. Harvest intensity increased significantly during the historic period, and populations were greatly reduced by the […]
