Anatomy of the “false thumb” of Tremarctos ornatus (Carnivora, Ursidae, Tremarctinae): phylogenetic and functional implications [PDF]

Estudios Geologicos, 2006
Se describe por primera vez el sesamoideo radial o “falso pulgar” del oso de anteojos (Tremarctos ornatus), mostrando la gran similitud morfológica con el del panda gigante (Ailuropoda melanoleuca) y las diferencias que presenta con el resto de los ...

An Annotated Draft Genome for the Andean Bear, Tremarctos ornatus. [PDF]

J Hered, 2021
AbstractThe Andean bear is the only extant member of the Tremarctine subfamily and the only extant ursid species to inhabit South America. Here, we present an annotated de novo assembly of a nuclear genome from a captive-born female Andean bear, Mischief, generated using a combination of short and long DNA and RNA reads. Our final assembly has a length

The Earliest Ursine Bear Demonstrates the Origin of Plant-Dominated Omnivory in Carnivora [PDF]

iScience, 2020
Summary: In Carnivora, increases in body size often lead to dietary specialization toward hypercarnivory. Ursine bears (Tremarctos and Ursus), however, are the only omnivorous Carnivora that evolved large body sizes (i.e., >50 kg). Traits contributing to

The highest altitudinal record of the Mountain coati Nasuella olivacea (Gray, 1865) for Ecuador [PDF]

Biodiversity Data Journal, 2018
The Mountain coati Nasuella olivacea is a species of carnivorous mammal, several aspects of its ecology and natural history remain unknown. In Ecuador, its presence is reported in high Andean forest and paramo between 1,300 and 3,700 m a.s.l., being rare

Predictive Modelling of Current and Future Potential Distribution of the Spectacled Bear (Tremarctos ornatus) in Amazonas, Northeast Peru [PDF]

Animals, 2020
The spectacled, or Andean, bear (Tremarctos ornatus) is classified as vulnerable by the IUCN due to climate change and human-induced habitat fragmentation. There is an urgent need for the conservation of spectacled bear at real time. However, the lack of

A Genetic Tool to Identify Predators Responsible for Livestock Attacks in South America and Recommendations for Human–Wildlife Conflict Mitigation [PDF]

Animals
Livestock predation induces global human–wildlife conflict, triggering the retaliatory killing of large carnivores. Although domestic dogs (Canis familiaris) contribute to livestock depredation, blame primarily falls on wild predators.

Andean bears (Tremarctos ornatus) display selective behaviors while foraging bromeliads (Puya spp.) in high elevation puna grasslands. [PDF]

PLoS ONE
Andean bears (Tremarctos ornatus) forage extensively on bromeliads (Puya spp.) across their range, although their selectivity for bromeliads is less understood. We report on foraging activity by Andean bears on two species of bromeliad, Puya leptostachya

Roads, forest cover, and topography as factors affecting the occurrence of large carnivores: The case of the Andean bear (Tremarctos ornatus)

Global Ecology and Conservation, 2021
Global declines in large-bodied terrestrial vertebrates are widely linked to human disturbance and habitat loss. Identifying remaining opportunities to conserve areas wherein such species may persist or might be reintroduced has thus become a key ...

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.
