The distribution of fitness effects during adaptive walks using a simple genetic network

This study models adaptation using a genetic network and finds that fitness effect distributions differ from theoretical expectations, showing fewer large-effect beneficial mutations and a bimodal distribution in the network model.

The influence of genetic structure on phenotypic diversity in the Australian mango (Mangifera indica) gene pool

This study examines how genetic structure in the Australian mango gene pool influences phenotypic diversity in tree size, fruit blush color, and intensity.

Adaptive divergence in shoot gravitropism creates hybrid sterility in an Australian wildflower

This study shows that adaptive divergence in shoot gravitropism contributes to hybrid sterility in Senecio lautus, linking local adaptation to speciation through reproductive isolation.

Metabolic scaling has diversified among species, despite an evolutionary constraint within species

The paper shows that metabolic scaling is evolutionarily constrained within species but diversifies across species in cockroaches.

Highly replicated evolution of parapatric ecotypes

This study shows that selection can repeatedly create similar ecotypes despite low gene flow between parapatric populations of Senecio lautus.

Phenotypic and genotypic parallel evolution in parapatric ecotypes of Senecio

This study examines phenotypic and genotypic parallel evolution in parapatric ecotypes of Senecio lautus, finding similar traits evolved through different genetic changes.

Local adaptation and hybrid failure share a common genetic basis

This study investigates the genetic basis of local adaptation and hybrid failure by analyzing hybrid populations of Australian daisies, finding that intrinsic reproductive isolation reduces adaptive genetic variation.

Evolution of genetic variance during adaptive radiation

The paper examines how genetic variance evolves during adaptive radiation by analyzing phenotypic and genetic divergence in ecotypes of an Australian wildflower across different environments.
