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.

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.

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

Genes & 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.

Exploring dietary adaptations in Ursus minimus: a 3D geometric morphometric analysis of the mandible

Boreas, Volume 55, Issue 2, Page 443-453, April 2026.
Using 3D geometric morphometrics, the dietary adaptations of the extinct Auvergne bear (Ursus minimus) are analysed. Its mandibular morphology aligns more closely with omnivorous rather than insectivorous bears, challenging current ideas. The extinct bear Ursus minimus, which lived in Europe during the Pliocene and possibly Early Pleistocene, is ...
