A positive association between gut microbiota diversity and vertebrate host performance in a field experiment

This study finds a positive link between gut microbiota diversity and host growth rate in threespine stickleback fish in a field experiment.

Heterosis counteracts hybrid breakdown to forestall speciation by parallel natural selection

The paper examines hybrid breakdown and heterosis in threespine stickleback fish ecotypes, finding environment-dependent outcomes and contrasting predictions about fitness consequences.

Genetic evidence for environment-dependent hybrid incompatibilities in threespine stickleback

The paper tests for environment-dependent hybrid incompatibilities in threespine stickleback by comparing excess heterozygosity in F2 hybrids raised in different environments.

Hybridization and the coexistence of species

The paper models coexistence of two sympatric species with incomplete reproductive isolation, showing hybrid fitness and assortative mating influence species survival and coexistence.

Adaptive divergence and the evolution of hybrid trait mismatch in threespine stickleback

This study shows that trait mismatch in threespine stickleback hybrids increases with parent population divergence, affecting F1 and F2 hybrids differently.

The latitudinal gradient in rates of evolution for bird beaks, a species interaction trait

This study examines bird beak evolution rates across latitudes, finding similar beak size evolution but faster beak shape evolution in temperate zones, supporting the empty niches hypothesis.

Patterns, predictors, and consequences of dominance in hybrids

This study examines hybrid phenotype patterns, finding hybrids often resemble one parent more than the other and show trait mismatches, with mismatch having a stronger fitness impact than parent bias.

Adaptation and latitudinal gradients in species interactions: nest predation in birds

The paper shows that nest predation rates in birds do not vary with latitude when accounting for nesting period length, suggesting adaptation may equalize evolutionary rates across latitudes.

Parallel changes in gut microbiome composition and function in parallel local adaptation and speciation

The paper examines parallel changes in gut microbiomes alongside local adaptation and speciation in stickleback fish, finding consistent microbial shifts associated with host divergence.

Behavior influences range limits and patterns of coexistence across an elevational gradient in tropical bird diversity

This study examines how behavioral interactions influence elevational range limits and coexistence patterns in tropical bird sister pairs across an elevational gradient.

Parallel genetic evolution and speciation from standing variation

This paper investigates how genetic parallelism and speciation progress under different directions of natural selection, finding that small directional differences reduce parallelism and affect hybrid fitness differently under parallel vs. divergent selection.
