Seasonal variation in stereotypic pacing in an American black bear Ursus americanus.
The behaviour of a male American black bear Ursus americanus was observed for over 2400 h across all seasons of the year. Stereotypic pacing was most frequent, oriented away from the exhibit, and performed mainly after feeding during the period May-July; from August-November pacing was oriented towards the exhibit and performed mainly around feeding time. Placing bear odors in the enclosure sli...
متن کاملTetranucleotide microsatellite loci from the black bear (Ursus americanus).
We describe primers and polymerase chain reaction conditions to amplify 21 tetranucleotide microsatellite DNA loci in black bears (Ursus americanus). We tested primers using individuals from two populations, one each in Georgia and Florida. Among individuals from Georgia (n = 29), primer pairs yielded an average of 2.9 alleles (range, one to four) and an average observed heterozygosity (H(O) ) ...
متن کاملSpatial memory in captive American black bears (Ursus americanus).
The spatial memory and foraging strategies of four adult captive-born American black bears (Ursus americanus) were explored in four experiments using a simulated foraging task. In the first three experiments, each session consisted of two phases separated by a delay: During the exploration phase, subjects foraged among a set of baited and unbaited sites. During the delay, the same locations wer...
متن کاملSeasonal regulation of the growth hormone-insulin-like growth factor-I axis in the American black bear (Ursus americanus).
The American black bear maintains lean body mass for months without food during winter denning. We asked whether changes in the growth hormone/insulin-like growth factor-I (GH-IGF-I) axis may contribute to this remarkable adaptation to starvation. Serum IGF-I levels were measured by radioimmunoassay, and IGF-binding proteins (IGFBPs) were analyzed by ligand blotting. Initial studies in bears li...
متن کاملNegative density-dependent dispersal in the American black bear (Ursus americanus) revealed by noninvasive sampling and genotyping
Although the dispersal of animals is influenced by a variety of factors, few studies have used a condition-dependent approach to assess it. The mechanisms underlying dispersal are thus poorly known in many species, especially in large mammals. We used 10 microsatellite loci to examine population density effects on sex-specific dispersal behavior in the American black bear, Ursus americanus. We ...
