Accurate Inference of the Polyploid Continuum using Forward-time Simulations

The paper introduces a forward-time polyploid genome evolution simulator to accurately infer WGD time and speciation parameters from Ks histograms, showing that existing methods are biased by allopolyploidy levels.

Go west: population genomics reveals unexpected population fluctuations and little gene flow in Western Hemisphere populations of the predatory lady beetle, Hippodamia convergens

This study uses ddRADseq to analyze population genetics of Hippodamia convergens, finding significant differentiation and no recent admixture despite population augmentation.

Shared patterns of population genomic variation and phenotypic response across rapid range expansions in two invasive lady beetle species

This study examines population genomic variation and phenotypic responses to photoperiod in two invasive lady beetle species across their range expansions in North America.

Like mother, like daughter? Phenotypic plasticity, environmental covariation, and heritability of size in a parthenogenetic wasp

This study investigates heritability, plasticity, and environmental covariation of body size in the parthenogenetic wasp Dinocampus coccinellae across different host environments, finding little heritable variation and a size-host tradeoff.

Lack of phenotypic variation despite population structure in larval utilization of pea aphids by populations of the lady beetle Hippodamia convergens

The study examines genetic and phenotypic differences in larval utilization of pea aphids by Western and Eastern populations of Hippodamia convergens, finding no phenotypic variation despite genetic structure.

Accounting for Gene Flow from Unsampled `Ghost' Populations while Estimating Evolutionary History under the Isolation with Migration Model

This paper evaluates biases in estimating evolutionary history when gene flow from unsampled ghost populations is not accounted for, using simulations and empirical data.

Chronic intake of high dietary sucrose induces sexually dimorphic metabolic adaptations in liver and adipose tissue

This study shows that high sucrose intake causes different metabolic changes in male and female mice, affecting liver and fat tissue, and highlights the role of sex in lipid storage and liver disease development.

Model-based Assessments of Differential Introgression and Linked Natural Selection During Divergence and Speciation

The paper develops a model-based method to assess differential introgression and linked natural selection during divergence and speciation using genomic data from multiple species.

Coccinellid host morphology dictates morphological diversity of the parasitoid wasp Dinocampus coccinellae

This study examines how host morphology affects the morphological diversity of the parasitoid wasp Dinocampus coccinellae across different host species.
