The past decade has seen a major breakthrough in our ability to easily and inexpensively
sequence genome‐scale data from diverse lineages. The development of high‐throughput …

Secondary contact between species often results in the formation of a hybrid zone, with the
eventual fates of the hybridizing species dependent on evolutionary and ecological forces …

Newts of the genus Triturus (marbled and crested newts) exhibit substantial variation in the
number of trunk vertebrae (NTV) and a higher NTV corresponds to a longer annual aquatic …

Since the early Holocene, fish population genetics in the Laurentian Great Lakes have been
shaped by the dual influences of habitat structure and post‐glacial dispersal. Riverscape …

Montane species endemic to the “sky islands” of the North American southwest were
significantly impacted by changing climates during the Pleistocene. We combined …

Human‐induced transformations of ecosystems usually result in fragmented populations
subject to increased extinction risk. Fragmentation is also often associated with novel …

Understanding polymorphism is a central problem in evolution and ecology, and alternative
reproductive tactics (ARTs) provide compelling examples for studying the origin and …

Understanding the processes that generate and maintain biodiversity at and below the
species level is a central goal of evolutionary biology. Here we explore the spatial and …

The mountains of southern California represent unique, isolated ecosystems that support
distinct high-elevation habitats found nowhere else in the area. Analyses of several moisture …

Speciation is the result of an accumulation of reproductive barriers between populations, but
pinpointing the factors involved is often difficult. However, hybrid zones can form when these …
