Spectacled bear predation and feeding behavior on livestock in Venezuela

Studies on Neotropical Fauna and Environment, 1991
Spectacled bear (Tremarctos ornatus) predatory behavior on cattle was studied in the Venezuelan Andes from February 1986 to November 1988. Only 12 of the 140 localities surveyed reported spectacled bear predation. Sixteen recent claims of predation were investigated, and predation by spectacled bear confirmed.

Feeding enrichment and stereotypic behavior in spectacled bears

Zoo Biology, 1999
The effect of feeding enrichment on the behavior of three spectacled bears (Tremarctos ornatus) was investigated in a large, complex zoo exhibit. Feeding enrichment significantly extended the time bears spent foraging, but no delayed effect on other behaviors was found. The frequency of stereotypic behaviors performed by an old female and a young adult

Tremarctos ornatus (Spectacled bear)

1977
Fibroblast cultures provided the karyotypes shown. The male specimen comes from Los Angeles Zoo, courtesy Dr. G. Kuehn, the female from National Zoo, Washington, D.C. through the courtesy of Dr. D.H. Wurster, Hanover, N.Y. Pairing is arbitrary in most cases, except the last pair of autosomes with characteristic secondary constriction.

The Primary Structure of the Hemoglobin of Spectacled Bear(Tremarctos ornatus,Carnivora)

Biological Chemistry Hoppe-Seyler, 1987
The complete primary structure of the alpha- and beta-chains of the hemoglobin of Spectacled Bear (Tremarctos ornatus) is presented. Following cleavage of the heme-protein link and chain separation by RP-HPLC, their amino-acid sequences were determined by Edman degradation in liquid- and gas-phase sequenators. The hemoglobin of Spectacled Bear displays

Situating the wildlife spectacle: ecofeminism, representation, and polar bear tourism

Journal of Sustainable Tourism, 2015
This paper presents a critical investigation of power relations circulating in promotional materials associated with polar bear tourism in Churchill, Manitoba, Canada. Drawing on precepts of ecofeminism, critical discourse analysis, and the content of cultural texts (websites, souvenirs) produced by tourism operators, businesses, and crown corporations,

Bear weight management: a diet reduction plan for an obese spectacled bear (Tremarctos ornatus)

Journal of Zoo and Aquarium Research, 2013
Spectacled bears (Tremarctos ornatus) are agile climbers and many aspects of behaviour in the wild are related to procuring food.  In captive situations obesity can result from reduced activity and offering food in excess of energy requirements if food is not presented in a way that encourages increased foraging time.

Models for management of wildlife populations: lessons from spectacled bears in zoos and grizzly bears in Yellowstone

System Dynamics Review, 2004
AbstractModels of population dynamics are frequently used in the management and conservation of wildlife populations. They provide a powerful method of quantitatively assessing a population's risk of decline and determining the potential to reverse the decline. Models from recent studies of managed populations are presented.
