When One Global Invasion Hides Another—Cryptic Interspecific Invasion in Freshwater Gastropods [PDF]
Aim Cryptic invasions are an understudied phenomenon among species invasions, especially in freshwater invertebrates. We study the gastropod family Physidae, including the global invaders Physella acuta and several enigmatic Stenophysa species, their ...

Where Do You Fly From? Assessing Aerial Dispersal in Temporary Rivers Using Stable Isotopes
Freshwater Biology, Volume 70, Issue 10, October 2025.ABSTRACT Dispersal is a crucial ecological process that facilitates gene flow and species exchange within ecosystems. In temporary rivers (TRs), dispersal is a key driver of community assembly because it determines the ability of the organisms to adapt to seasonal drying and maintain stable populations.

Using fecal DNA metabarcoding to investigate the animal diet of black rails, yellow rails, and soras
Wildlife Society Bulletin, Volume 49, Issue 3, September 2025.We used fecal DNA metabarcoding to investigate the diet of yellow rails, Eastern black rails, and sora during the non‐breeding season. Arthropods, particularly ants, were prevalent in their diets, suggesting possible interactions with invasive red imported fire ants.

Journal of Animal Ecology, Volume 94, Issue 9, Page 1811-1822, September 2025.Individual niche specialisation is widespread within animal populations and can have important ecological consequences. Predation and competition are known drivers of individual specialisation, but their combined effects are unstudied. This mesocosm experiment shows that competition and predation from a single antagonist can have variable effects on ...

Shearing Tooth Morphology May Allow Sharks to Access Higher Trophic Levels at Smaller Sizes
Ecology and Evolution, Volume 15, Issue 8, August 2025.Predator morphology imposes limitations on prey selection due to biomechanical constraints, making some prey functionally inaccessible and thereby constraining predator trophic niches. We assessed how two key components of trophic morphology—tooth shape and body size—affect prey selectivity and trophic niche in two sympatric sharks with contrasting ...
