Effects of competition and predation risk from a life history intraguild predator on individual specialisation

open access: yesJournal of Animal Ecology, EarlyView.
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 ...

ORDNA: Deep‐learning‐based ordination for raw environmental DNA samples

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Environmental DNA (eDNA) metabarcoding has revolutionized biodiversity monitoring, offering non‐invasive tools to assess ecosystem health. The complexity of eDNA metabarcoding data poses major challenges for conventional ordination methods in understanding assemblage similarities and assessing biodiversity patterns.
