PS45 – Hair as a Potential Non-Invasive Indicator of Renal Mercury Accumulation in Brown Bears
Ena Oster, University of Zagreb, Faculty of Veterinary Medicine Mercury (Hg) is a globally distributed contaminant that accumulates in wildlife tissues and can cause nephrotoxic, haematotoxic, neurotoxic, and negative reproductive […]
PS59 – Haematological reference intervals for free-ranging brown bears in the Greater Yellowstone Ecosystem
Agnieszka Sergiel, Institute of Nature Conservation of Polish Academy of Sciences Haematological parameters are key indicators of blood function and provide valuable insight into animal health and physiological responses to […]
PS37 – Neurotoxicity thresholds for non-essential trace elements: assessing risk in bears
Joanna Macur, Institute of Nature Conservation Polish Academy of Science Non-essential trace elements (TEs) are well-known environmental contaminants that lack a defined biological function in mammals. Although TEs occur naturally, […]
OS33 – Quantitative measures of body size and body condition from wild Andean bears in Peru
Russell C. Van Horn, Garth Mowat, Rebecca Zug Size and body condition of wild bears are known to reflect their ecology, especially habitat quality, and have been found to be […]
PS03 – Application of novel genomic methodologies to non-invasively identify fine-scale forage of brown bear (Ursus arctos) in southwest Alaska.
Noah Andexler, Northern Michigan University For omnivorous species such as brown bear (Ursus arctos), diverse diets make forage identification challenging using traditional methods (e.g., scat dissection and stable isotope analysis). […]
PS06 – Bear Jaws and Claws: A Biomechanical Breakdown
Fern Bendio, Brigham Young University- Provo To determine the minimum canine bite force and claw force of polar bears (Ursus maritimus) relevant to human–bear interactions, we measured the force required […]
OS49 – Niche variation in polar bears across heterogeneous sea-ice environments
Andrew Derocher, James Roth, Geoff Koehler, Kevin Kardynal, David McGeachy, Nicholas Pilfold, Keith Hobson Intraspecific competition, including conspecific killing, can structure populations by driving niche partitioning through differentiated diet or […]
OS43 – Stable isotope analysis reveals physiological strategies for body water management in polar bears (Ursus maritimus)
Anthony M. Pagano, Karen Caceres, John P. Whiteman Animals must remain in water balance to support their physiological function. The polar bear (Ursus maritimus) range is characterized by limited availability […]
