The Primary Structure of the Hemoglobin of Spectacled Bear(Tremarctos ornatus,Carnivora)
Biological Chemistry Hoppe-Seyler, 1987The 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, 2015This 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, 2013Spectacled 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.

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.

The role of the spectacled bear (Tremarctos ornatus) as an umbrella species for Andean ecoregions
Wildlife Research, 2019Context The concept of umbrella species has been proposed as a surrogate for the conservation of a wider range of species and ecosystems. This concept has, however, frequently been questioned by researchers because of the lack of empirical evidence to support it.

Ecology, Distribution, and Food Habits of Spectacled Bears, Tremarctos ornatus, in Peru
Journal of Mammalogy, 1980A study of the behavior and ecology of the spectacled bear, Tremarctos ornatus , in Peru revealed that they occur in all three ranges of the Peruvian Andes, with the majority in the “ceja de selva,” or eastern slope of the Cordillera Oriental. As evidenced by feeding sign and contents of scats, 83 foods were confirmed in the diet of spectacled bears ...
