Evidence for kilometer-scale biophysical features at the Gulf Stream front

This study investigates how submesoscale frontal dynamics at the Gulf Stream front affect biological communities and productivity, finding two key processes linked to meander phases that influence phytoplankton biomass and composition.

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.

START domain mediates Arabidopsis GLABRA2 transcription factor dimerization and turnover independently of homeodomain DNA binding

This study investigates the role of the START domain in GLABRA2 dimerization and protein turnover, showing it is independent of DNA binding and essential for stability.

Arabidopsis PROTODERMAL FACTOR2 binds lysophosphatidylcholines and transcriptionally regulates phospholipid metabolism

This study shows that PDF2, an HD-Zip IV TF, binds lysophosphatidylcholines via its START domain and regulates phospholipid metabolism in response to phosphate availability.

The diverse effects of phenotypic dominance on hybrid fitness

This study examines how phenotypic dominance affects hybrid fitness using Fisher's geometric model, showing dominance often reduces fitness and can lead to outbreeding patterns and violations of Haldane's Rule.

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.

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.

Climate warming weakens local adaptation

The paper quantifies how climate change impacts population performance by analyzing temperature and precipitation effects, finding that local adaptation to temperature is critical and deviations reduce performance.

Multivariate phenotypic divergence along an urbanization gradient

The paper measures multiple phenotypic traits in white clover populations along an urbanization gradient, finding urban populations exhibit divergence in several traits including phenology, flower size, and pollinator attraction.

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.

Evidence that pleiotropic alleles underlie adaptive divergence between natural populations

The paper tests whether adaptive divergence between natural populations involves pleiotropy and compensation by analyzing segregation variance in hybrid offspring.

Predicting the strength of urban-rural clines in a Mendelian polymorphism along a latitudinal gradient

The paper examines urban-rural clines in a Mendelian trait of white clover across cities, finding that winter conditions influence HCN frequency changes, with snow reducing selection pressure in colder cities.

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.

Induced defenses alter the strength and direction of natural selection on reproductive traits in common milkweed

This study shows induced defenses in common milkweed change the strength and direction of natural selection on reproductive traits, independent of foliar damage.

CRISPR/Cas9-Assisted Transformation-Efficient Reaction (CRATER), a novel method for selective transformation

The paper introduces CRATER, a CRISPR/Cas9-based method that improves plasmid transformation efficiency by selectively cleaving unwanted byproducts, increasing efficiency from 20% to 97%.
