Hummingbird interaction niche packing is influenced by species richness and resource availability in the southern tropical Andes

Functional Ecology, Volume 40, Issue 7, Page 2275-2285, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Niche partitioning is often considered an important mechanism promoting species co‐occurrence in species‐rich communities. As species richness increases, niche partitioning may lead to different niche structures, including increased packing of species niches when the ...

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 ...

Conservation priorities for Neotropical water striders (Hemiptera: Heteroptera: Gerridae) under climate change

Conservation Science and Practice, Volume 8, Issue 7, July 2026.
Hydrologic changes driven by climate change are affecting aquatic biota in the Neotropical Region, with significant impacts on water striders. Species distribution models predict an increase in conservation importance for the northern Andes and coastal areas of eastern South America, while central South America shows a decline. The observed changes are

Climate Warming Drives Northward Contraction and Genetic erosion in a Cold‐Adapted Soil Worm Species

Diversity and Distributions, Volume 32, Issue 7, July 2026.
ABSTRACT Aim Climate‐driven range fluctuations since the Pleistocene have repeatedly reshaped species distributions and population structures, with lasting consequences for genetic diversity. Contemporary warming causes similar pressures, yet most work emphasizes range shifts and gives less attention to genetic outcomes.

Setting Priorities for the Acquisition of Primary Plant Occurrence Data

Diversity and Distributions, Volume 32, Issue 7, July 2026.
ABSTRACT Aim Effective implementation of the Global Biodiversity Framework and Global Strategy for Plant Conservation relies on accurate species distribution data. However, current vascular plant distribution data are often sparse and biased, requiring significant expansion.

Do Coexisting Cryptic Species of Predatory Peacock Bass (Cichliformes: Cichlidae) Partition Their Niche?

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT The mechanisms facilitating coexistence of cryptic species in sympatry have long puzzled ecologists. Cryptic species have nearly identical morphology and, therefore, would be presumed to have high niche overlap and potential for interspecific competition and competitive exclusion when resources are limited. Lowland rivers in South America have

Challenges and Advances Driving Studies on Aquatic Insects of the Order Coleoptera

Freshwater Biology, Volume 71, Issue 7, July 2026.
ABSTRACT Aquatic beetles (Coleoptera) are known for their high taxonomic and ecological diversity and their sensitivity to environmental changes, making them key bioindicators in ecological assessments. However, numerous knowledge gaps persist globally.
