Tropical Bee Assemblage Diversity Decreases With Elevation While Body Size Increases

Biotropica, Volume 58, Issue 4, July 2026.
Photos of bee specimens collected in the Colombian Andes across a nearly 3000 m elevational cline. They are arranged to illustrate both the decline in richness with elevation and the increase in community average body size with elevation. ABSTRACT Elevation gradients are powerful drivers of changes in species composition, richness, and functional ...

Is There Life After Death? The Role of Standing Dead Phorophytes in Supporting Tropical Epiphyte Diversity

Biotropica, Volume 58, Issue 4, July 2026.
ABSTRACT Global increases in tree mortality from climate change and land‐use are altering forest structures, impacting canopy‐dwelling plants like vascular epiphytes, which depend on host trees (phorophytes). When a phorophyte dies standing, it becomes a snag, the local substrate conditions change and microclimatic exposure may increase, particularly ...

Reef fish assemblages impacted by sponges overgrowing corals

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract Numerous stressors are driving long‐term declines in coral cover on coral reefs, significantly impacting reef fish biodiversity and community structure. The benthic space made available by declining coral cover is often occupied by increases in other organisms, including macroalgae, encrusting ascidians, and sponges.

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas

Conservation Biology, Volume 40, Issue 3, June 2026.
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

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

Conservation 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 ...
