The Red Queen unveils the sexual and mating strategies of flowers

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
Although the conventional wisdom is that floral traits of plants evolved in concert with their mutualistic pollinators, here we showed that several key sexual and mating traits of plants, which modulate their outcrossing strategy, evolved in response to the pressure exerted by their antagonistic insect herbivores.

Environmental Contamination Affects Associated Bacterial Communities in a Neotropical Arboreal Ant

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
Environmental stressors such as contamination from mining tailings can alter microbial communities associated with insects, including social ants. Ants, as widespread and ecologically influential insects with stable microbial associations, offer a relevant model to examine these effects.

The Flooding Gradient Affects Seed Dispersal by Fruit‐Eating Fishes in Amazonian Whitewater Floodplain Forests

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
This research approaches the interaction between frugivorous fish and the flooded forests in the central Amazon. We evaluated the fruit consumption by fish and the seed dispersal potential along the flood gradient. We tested the hypothesis that the role of fish as seed dispersers varies between low várzea (LV) and high várzea (HV) forests.

Ultrasonographic diagnosis of caudoproximal humeral stress fracture in thoroughbred racehorses

open access: yesEquine Veterinary Journal, Volume 58, Issue 3, Page 788-796, May 2026.
Abstract Background Humeral stress fractures in racehorses can progress to catastrophic fracture if unrecognised. Scintigraphy is the gold standard diagnostic technique but is limited by accessibility and cost. It was hypothesised that ultrasonography could be used to visualise caudoproximal humeral stress fractures. Objectives To determine the utility
