Generalist With a Narrow Niche Breadth: Feeding Ecology and Seed Germination Effectiveness of a Large Canid Within a Silvicultural Matrix

open access: yesAustral Ecology, Volume 51, Issue 6, June 2026.
Diet: The generalist canid exhibits a narrow niche breadth (0.12), consuming native plants (100% frequency) and animals (85%). Birds dominate animal prey (74%), peaking in the dry season, while Solanaceae plants dominate plant food (100%), peaking in the rainy season.

Functional homogenization of terrestrial mammals outside protected areas in the Hengduan Mountains, China

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

High Densities of Large Herbivores Rapidly Disrupt Ecosystem Integrity

open access: yesGlobal Change Biology, Volume 32, Issue 6, June 2026.
Human‐driven increases in large herbivore populations are emerging as a widespread global change pressure on terrestrial ecosystems. Using the largest hectare‐scale herbivore density manipulation experiment conducted to date, we show that high deer densities rapidly disrupt ecosystem integrity across multiple dimensions of biodiversity and ecosystem ...

The Most Elusive Amazonian Mammal? Distribution, Survey, Ecology and Conservation of the Bushy‐Tailed Opossum Glironia venusta

open access: yesMammal Review, Volume 56, Issue 2, June 2026.
Integrating multiple data sources, we reveal a broader distribution for Glironia venusta and highlight how sampling strategies shape our understanding of rare arboreal mammals. ABSTRACT Introduction Arboreal and nocturnal mammals in the Amazon remain poorly understood due to low detectability and methodological limitations. Glironia venusta, one of the

Patterns of frugivory in the columnar cactus Pilosocereus leucocephalus

open access: yesEcology and Evolution, 2019
In the frugivory networks of many arid and semi‐arid Mesoamerican ecosystems, columnar cacti act as keystone species that produce fruits with a high content of water and nutrients attractive to numerous vertebrates.
