Microsatellite Analysis of the Spectacled Bear (Tremarctos ornatus) Across its Range Distribution

Genes and Genetic Systems, 2005
DNA samples of the spectacled bear (Tremarctos ornatus) from five Andean countries, Venezuela, Colombia, Ecuador, Peru and Bolivia, were analyzed for nine microsatellite loci. Seven of them were polymorphic, which led us to investigate several population-genetic parameters.

Environmental enrichment for the captive spectacled bear (Tremarctos ornatus)

Pharmacology Biochemistry and Behavior, 2002
As part a series of investigations of environmental enrichment methods for zoo animals, two spectacled bears (Tremarctos ornatus) were observed for 40 h, documenting use of cage space and behaviors, using a detailed ethogram. Baseline data showed concentration of activity into limited areas of the enclosure and expression of a relatively restricted ...

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

The role of the spectacled bear (Tremarctos ornatus) as an umbrella species for Andean ecoregions

Wildlife Research, 2019
Context 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, 1980
A 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 ...
