Unravelling the drivers of island species richness in tropical savannas

Journal of Ecology, Volume 114, Issue 4, April 2026.
Murundu island area explains a substantial proportion of the variation in tree and herb richness, consistent with Island Biogeography Theory. On average, a 10% increase in island size corresponds to increases of seven tree species and 7.8 herb species.

Importance of connectivity for carnivore richness and occupancy in fragmented biodiversity hotspots

Conservation Biology, Volume 39, Issue 6, December 2025.
Abstract Structural connectivity affects wildlife movement between habitat patches, contributing to the persistence of wildlife populations and their resilience to human‐induced and environmental changes. However, its importance to wildlife population persistence remains unclear, particularly in fragmented landscapes, where there are additional co ...

Human development, societal stability and bird capital predict global tourist eBirding activity

People and Nature, Volume 7, Issue 10, Page 2486-2499, October 2025.
Abstract Birdwatching tourism is one of the fastest growing sectors within nature‐based tourism. This specialized form of ecotourism has the potential to bring economic and conservation benefits to tropical countries, which house the richest avifaunas, but little is known about the factors driving birdwatchers' decisions about which country to visit ...

PhyBaSE: A Bayesian structural equation model approach to causal inference in phylogenetic comparative analyses

Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1136-1148, June 2025.
Abstract One of the main limitations of phylogenetic comparative analyses is that associations between traits can only be interpreted as correlations. Here, we present a novel Bayesian structural equation model (PhyBaSE) which allows us to disentangle direct from indirect relationships among variables to propose potential causal hypotheses while ...
