Eltonian Niche Modelling: Applying Joint Hierarchical Niche Models to Ecological Networks

open access: yesEcology Letters, Volume 28, Issue 6, June 2025.
We adapt joint species distribution models (JSDMs) to data on ecological networks, functional traits, and phylogenies to model species' Eltonian niches. Our Eltonian JSDMs reveal strong relationships between species' Eltonian niches and their functional traits, and they can even be used to predict the interactions of species for which no empirical ...

Frequent Hybridisation Between Parapatric Lekking Bird‐of‐Paradise Species

open access: yesMolecular Ecology, Volume 34, Issue 11, June 2025.
ABSTRACT Hybridisation is known to occur between a wide range of taxa, including species for which strong sexual selection has led to markedly different sexual phenotypes and lek‐mating behaviours. To what extent occasional hybridisation can overcome the reproductive barriers in such systems and, for example, lead to the establishment of hybrid zones ...
