Boreas, Volume 55, Issue 2, Page 503-516, April 2026.Bears deviate from the inhibitory cascade model (ICM) during molar size evolution, with two significant deviations linked to changes in diet: Ursus minimus and Ursus deningeri. Many bears exhibit a ‘partial ICM’, highlighting the relationship between relative molar size, dietary adaptations and dental development across different species.

Range fragmentation in the spectacled bear Tremarctos ornatus in the northern Andes [PDF]
Oryx, 2004 This paper addresses the conservation status of the spectacled bear Tremarctos ornatus in the northern Andes (Venezuela, Colombia and Ecuador) by analysing the degree of range fragmentation and estimating habitat availability. From satellite images we constructed maps of remnant habitat blocks, consisting of Andean forest and páramo (high elevation ...

Importance of connectivity for carnivore richness and occupancy in fragmented biodiversity hotspots
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Structural connectivity affects wildlife movement between habitat patches, contributing to the persistence of wildlife populations and their resilience to human‐induced and environmental changes. However, its importance to wildlife population persistence remains unclear, particularly in fragmented landscapes, where there are additional co ...

Ecology and Evolution, Volume 15, Issue 5, May 2025.Age is an essential factor to understand the life history and demographic parameters of wildlife. In this study, we built a common epigenetic clock model for multiple bear species, including brown, Asian black, polar, sun, and Andean bears. The model will contribute to ecological research, conservation, and management of bear species.

Molecular Ecology Resources, Volume 25, Issue 4, May 2025.ABSTRACT Illegal wildlife trade is a growing problem internationally. Poaching of animals not only leads to the extinction of populations and species but also has serious consequences for ecosystems and economies. This study introduces a molecular marker system that authorities can use to detect and substantiate wildlife trafficking.
