The Anatomical Record, Volume 309, Issue 7, Page 1702-1712, July 2026.Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

Ecology and Evolution, Volume 16, Issue 7, July 2026.This article provides new insights into the diet and reproductive biology of the Spix's night monkeys (Aotus vociferans). This evidence was collected using arboreal camera traps in a tropical mountain rainforest in Southern Ecuador, where documented information on this primate is rare.

Semina: Ciências Agrárias, 2013 Preventing expansion into areas not yet infested is a priority standard for controlling mesquite. The contamination of other areas occurs through the flocks (endozoochory), which disperse the seeds in different areas to consume fruits, facilitating the ...

Ecology and Evolution, Volume 16, Issue 7, July 2026.We evaluated nectar robbery by native and invasive bumblebees in the hummingbird‐pollinated shrub Desfontainia fulgens in southern Chile. Nectar robbery strongly reduced nectar standing crop and altered floral visitation patterns, but these proximate effects did not translate into reduced seed production under natural pollination conditions.

Ecology and Evolution, Volume 16, Issue 7, July 2026.Color variations in mammals are uncommon but can provide insight into genetic and ecological patterns within populations. We documented a high prevalence of piebaldism in Syntheosciurus granatensis in northwestern Ecuador using camera‐trap bycatch (2014–2024), verified iNaturalist observations, and collaborator records, with 31.9% of all independent ...

Diel and Artificial Light Effects on Nearshore Communities Revealed by eDNA Metabarcoding
Environmental DNA, Volume 8, Issue 4, July‐August 2026.Environmental DNA revealed rapid, taxon‐specific community reorganization across diel and artificial light conditions in a nearshore marine ecosystem. Distinct responses among trophic groups indicate that artificial light at night reshapes predator–prey interactions and community structure within 30 min of exposure.

Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens
PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1304-1321, July 2026.Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...
