Serologic Survey for Leptospirae in European Brown Bears (Ursus arctos) in Croatia

Management of Brown Bears (Ursus arctos) in Europe

Genetic relationships of extant brown bears (Ursus arctos) and polar bears (Ursus maritimus).

Polar bears (Ursus maritimus) and brown bears (Ursus arctos) are closely related species for which extensive mitochondrial and nuclear phylogenetic comparisons have been made. We used previously published genotype data for 8 microsatellite DNA loci from 930 brown bears in 19 populations and 473 polar bears in 16 populations to compare the population genetic relationships of extant populations o...

Physiology of the European brown bear (Ursus arctos arctos)

Although the American black (Ursus americanus) and American brown (grizzly) (Ursus arctos horribilis) bears have been the subjects of intensive physiological research, very little so far, has been done to understand the physiology of the European brown bear (Ursus arctos arctos). In our laboratory the research on the physiology of European brown bears started 10 years ago. Between 1987 and 1997...

Treatment of hypoxemia during anesthesia of brown bears (Ursus arctos).

This study assessed whether arterial oxygenation could be increased by treatment with intranasal oxygen supplementation in brown bears (Ursus arctos) with hypoxemia during anesthesia with medetomidine-zolazepam-tiletamine. Arterial blood samples were collected anaerobically from the femoral artery before and during oxygen supplementation. An oxygen flow rate of 2-5 L/min administered intranasal...

A forensic DNA profiling system for Northern European brown bears (Ursus arctos).

A set of 13 dinucleotide STR loci (G1A, G10B, G1D, G10L, MU05, MU09, MU10, MU15, MU23, MU26, MU50, MU51, MU59) were selected as candidate markers for a DNA forensic profiling system for Northern European brown bear (Ursus arctos). We present results from validation of the markers with respect to their sensitivity, species specificity and performance (precision, heterozygote balance and stutter ...
