Environmental DNA metabarcoding reveals biodiversity recovery in tropical forest restoration across multiple landscapes

Ecosphere, Volume 17, Issue 7, July 2026.
Abstract Forest ecosystems have been degraded globally and restoration efforts aim to reverse loss of biodiversity and ecosystem function decline including carbon storage from the atmosphere. Assessments of restoration success predominantly emphasize increasing carbon stocks rather than species recovery.

Was the giant short-faced bear a hyper-scavenger? A new approach to the dietary study of ursids using dental microwear textures.

PLoS ONE, 2013
Dramatic environmental changes associated with global cooling since the late Miocene, and the onset of glacial-interglacial cycles in the Pleistocene served as a backdrop to the evolutionary radiation of modern bears (family Ursidae). These environmental

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 ...

Threats to the World's Bears and Efforts to Conserve Them: Perspectives and Actions of IUCN Bear Specialist Group Members 世界熊类面临的威胁及其保护努力:IUCN熊类专家组成员的观点与行动

Integrative Conservation, Volume 5, Issue 2, Page 177-191, June 2026.
A survey of IUCN Bear Specialist Group (BSG) members revealed that habitat loss, degradation and fragmentation is the greatest threat to each of the 7 species of terrestrial bears. Poaching and human–bear conflicts are also high threats for some of these species.

Dietary ecology of the extinct cave bear: Evidence of omnivory as inferred from dental microwear textures [PDF]

Acta Palaeontologica Polonica, 2016
The diet of the extinct European cave bear, Ursus spelaeus, has widely been debated. Diverging from the extant brown bear (Ursus arctos) approximately 1.2 million years ago, the cave bear is one of the most ubiquitous fossil bears occurring in Europe ...

An Ecological Modelling Approach to Support Peru Wildlife Conservation Planning Based on Geospatial Datasets and Remote Sensing Information

Diversity and Distributions, Volume 32, Issue 5, May 2026.
ABSTRACT Aim Peru, a megadiverse country, has developed conservation plans for some threatened wildlife species. This study produced spatially explicit data integrating Species Distribution Models (SDMs) into a geospatial analysis of connectivity within the protected areas (PAs) network.

Estimación de la masa corporal de las especies de osos fósiles y actuales (Ursidae, Tremarctinae) de América del Sur Body mass estimation of extinct and extant South American bears (Ursidae, Tremarctinae)

Revista del Museo Argentino de Ciencias Naturales, 2009
Contar con estimaciones precisas de la masa corporal de los taxones fósiles es esencial para realizar reconstrucciones paleobiológicas. Empleando relaciones demostradas entre la masa corporal y medidas anatómicas en mamíferos modernos algunos autores han
