Abstract. Large phylogenetic trees are often unbalanced near the root, with a species-depauperate lineage sister to a far more species-rich clade. The spec

Genomic inversions spanning many genes can persist for millions of years. This study of Trinidadian guppy populations reveals how both ecological conditions and mate choice help maintain this hidden l...

Polymath ecologist whose research and textbooks integrating ecology and evolution have inspired generations of students.

View Projected Impact of the FY2027 Budget Cuts to the NIH and NSF

The selection of environmental variables is a cornerstone of biogeographical analyses. However, most studies use standard sets of predictors, without …

By doubling their entire genome, organisms can evolve extremely rapidly — or they can lose it all. New studies reveal how to survive the high-risk, high-reward evolutionary event.

Community ecology has developed a rich and increasingly diverse body of theory, but its rapid expansion has outpaced efforts to compare and synthesize competing frameworks. As a result, semantic ambig...

Abstract. Environmental shifts often dictate Arthropod morphological evolution, yet certain lineages maintain remarkably conserved body plans across divers

Aim Species Distribution Models (SDMs) have traditionally been developed in a terrestrial context, and their application to aquatic ecosystems presents unique challenges. These include predicting sp...

Databases and submission systems are often inflexible. Can’t publishers do more on author names?

My keynote at ICML 2026

The idea that artificial intelligence can “reason” is more intuitive than ever. But intuitions can be wrong, and the science is far from settled.

A model developed by WashU biologists suggests infected foreigners were not the primary drivers of international outbreaks

Adaptive potential determines how populations respond to environmental change. This study compiles evolvability estimates from over 170 multicellular species, revealing substantial variation across th...

Ancestral range reconstruction supports an early widespread Afro–Eurasian distribution, rather than a single-region origin, reflecting connectivity among Africa, Europe and Asia during the Tertiary......
