After All, Size Does Matter: Size and Trachemys Scripta Reproduction Traits at the Western Limit of Its European Distribution

Integrative Zoology, EarlyView.
‐ Female T. scripta exhibit a clear size‐dependent reproductive investment, where larger plastron length is positively associated with all key reproductive traits. ‐ Female T. scripta reach sexual maturity at a plastron length of approximately 15–18 cm. ABSTRACT In invasive species, reproductive success may determine invasion outcomes and influence the

Enhanced fish detection sensitivity in aquatic systems using environmental RNA

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental RNA (eRNA) can potentially augment the biological monitoring ability of the established environmental DNA (eDNA) application in conservation. Despite faster degradation, environmental RNA could offer unique advantages: it may help reduce the legacy signal compared to eDNA, provide insights into physiological status through gene ...

EMITS: Expectation–maximization abundance estimation for fungal ITS communities from long‐read sequencing

Methods in Ecology and Evolution, EarlyView.
Abstract As long‐read amplicon sequencing becomes routine for fungal metabarcoding, species‐level abundance estimation from ITS amplicons remains limited by naive best‐hit classification. Assigning each read to its single highest‐scoring reference misattributes reads among closely related species that share similar ITS sequences, and divides the reads ...

Hidden Losses: Assessing the Risk of Coextinction Among Ectoparasitic Flies and Their Bat Host Species in Brazil

Animal Conservation, EarlyView.
The potential impact of bat species extinction on the number of their ectoparasitic fly species, based on interaction data for Brazil. As bat host species are removed over time, more connected species (green) would experience steeper declines and lead to greater ectoparasite losses when compared to a random extinction model (gray).
