This paper identifies common drivers of genetic structure in riverine fish communities using a comparative approach to genetic beta-diversity across multiple species.

The paper uses phenotypic traits to predict genetic diversity in freshwater fish species across the Ozarks, finding that traits explain 31-68% of genetic variability.

The paper examines hybridization across 75 freshwater fish communities using SNP genotyping, finding widespread hybridization and environmental predictors.

The paper creates pesticide use datasets and mapping methods for the contiguous U.S. to support pollinator conservation and research.

This study examines hybridization and biogeography in Massasauga rattlesnakes using ddRAD sequencing, revealing population structure and historical range dynamics shaped by climate change.

The study investigates elevational ecotypes in polyploid snowtrout, finding that parallel introgression, not recurrent emergence, explains morphological convergence across drainage systems.

The paper introduces ResistNet, a framework for analyzing dendritic ecological networks by aligning genetic distances with environmental covariates, and evaluates it using ddRAD data from Speckled Dace.

The paper assesses metapopulation connectivity in voles to evaluate tallgrass prairie restoration success and its implications for Lyme disease transmission.

This paper tests the hypothesis that Himalayan uplift dispersed aquatic biodiversity by analyzing the phylogeography of Snowtrout fish across Asia.

This paper investigates the biogeography and speciation patterns in the Tiger Whiptail complex using mitochondrial DNA sequences to test taxonomic hypotheses and identify genetic divergence drivers.

The paper uses genomic and spatial data to resolve taxonomic uncertainty in the Gila robusta complex, finding three distinct species despite phylogenetic discordance caused by rapid radiation.

The paper uses population genomic analyses to determine if bonefish and queen conch populations in the northern Caribbean Basin are open or closed, finding genetic structure in conch and asymmetrical gene flow in bonefish.

The paper evaluates machine learning-based species delimitation in North American box turtles using ddRAD SNP data with varying filtering strategies, finding that phylogenetic discordance affects classification.

The paper uses genome-wide local ancestries to distinguish homoploid hybrid speciation from secondary introgression in red wolves, revealing ancient divergence masked by recent gene flow.

This study uses ddRAD sequencing to analyze gene flow and species boundaries in two fish species, identifying new lineages and introgression patterns in the Colorado River system.

The paper estimates insect toxic load from US agricultural insecticides between 1997-2012, finding a 9-fold increase in oral toxicity despite reduced application volumes, driven by higher potency and expanded use areas.

This study examines hybridization between two sympatric desert fish species in the Colorado River Basin, finding genetic erosion and hybrid swarms linked to anthropogenic habitat modifications.

This study identifies heparan sulfate as a critical regulator of G6b-B, showing it inhibits platelet and megakaryocyte function through Shp1/Shp2 signaling.
