Non‐random mating among individuals can lead to spatial clustering of genetically similar
individuals and population stratification. This deviation from panmixia is commonly observed …

Invasive freshwater fishes are known to readily hybridize with indigenous congeneric
species, driving loss of unique and irreplaceable genetic resources. Here we reveal that …

Background The study of speciation has expanded with the increasing availability and
affordability of high-resolution genomic data. How the genome evolves throughout the …

Describing how hybrid zones respond to anthropogenic influence can illuminate how the
environment regulates both species distributions and reproductive isolation between …

Dams have negatively affected freshwater biodiversity throughout the world. These negative
effects tend to be exacerbated for aquatic taxa with migratory life histories, and for taxa …

Hybrid zones have been viewed as an opportunity to see speciation in action. When hybrid
zones are replicated, it is assumed that if the same genetic incompatibilities are maintaining …

Extreme F2 phenotypes known as transgressive segregants can cause increased or
decreased fitness in hybrids beyond the ranges seen in parental populations. Despite the …

Closely related species that have previously inhabited geographically separated ranges are
hybridizing at an increasing rate due to human disruptions. These human‐mediated hybrid …

Creek chub (Semotilus atromaculatus) is a leuciscid minnow species commonly found in
anthropogenically disturbed environments, making it an excellent model organism to study …

Hybridization dynamics between co‐occurring species in environments where human‐
mediated changes take place are important to quantify for furthering our understanding of …
