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 ...

Restricted Dispersal in the Late Successional Forest Tree Species Nothofagus Pumilio: Consequences Under Global Change

Ecology and Evolution, Volume 15, Issue 5, May 2025.
We aim to uncover the current and historic effective dispersal distances and characterize fine‐scale genetic structure in the forest tree species Nothofagus pumilio. Short seed dispersal distances mean N. pumilio distribution expansion capacity may be limited, especially in the context of global change.
