Hybridization but minimal introgression: ecologically-based divergent selection maintains a steep hybrid zone in parapatric stickleback fish Open
Steep hybrid zones provide key insights into the mechanisms of speciation by reflecting incomplete reproductive isolation between diverging populations. However, the specific reproductive barriers preventing the fusion of such populations …

<span>PROCEED</span> v6.1: Phenotypic rates of change evolutionary and ecological database Open
Populations must continuously respond to environmental change or risk extinction. These responses can be measured as phenotypic rates of change, which allow researchers to predict their contemporary evolutionary responses. In 1999, a datab…

Warming leads to opposite patterns in weight-at-age for young versus old age classes of Bering Sea walleye pollock Open
The temperature–size rule predicts that climate warming will lead to faster growth rates for juvenile fishes but lower adult body size. Testing this prediction is central to understanding the effects of climate change on population dynamic…

The Pace of Modern Life, Revisited Open
Wild populations must continuously adapt to environmental changes or they risk extinction. Such adaptations can be measured as phenotypic rates of change and can allow us to predict patterns of contemporary evolutionary change. About two d…

Clinal genomic analysis reveals strong reproductive isolation across a steep habitat transition in stickleback fish Open
How ecological divergence causes strong reproductive isolation between populations in close geographic contact remains poorly understood at the genomic level. We here study this question in a stickleback population pair adapted to contiguo…

Recent declines in salmon body size impact ecosystems and fisheries Open
Declines in animal body sizes are widely reported and likely impact ecological interactions and ecosystem services. For harvested species subject to multiple stressors, limited understanding of the causes and consequences of size declines …

Genetic insights into the past, present, and future of a keystone species Open
In a new paper in PNAS, Thompson et al. (1) examine the genetic legacy of a struggling keystone species—and the implications for a phoenix-like recovery from its genetic remnants. For thousands of years before European contact, indigenous …

Sexual dimorphism modifies habitat‐associated divergence: Evidence from beach and creek breeding sockeye salmon Open
Studies of parallel or convergent evolution (the repeated, independent evolution of similar traits in similar habitats) rarely explicitly quantify the extent of parallelism (i.e. variation in the direction and/or magnitude of divergence) b…

(Non)parallel evolution in North American post-glacial fishes Open
Parallel evolution, the repeated, independent evolution of similar traits in similar environments, has played an important role in evolutionary biology, in part because repeated, habitat-associated divergence provides evidence for a determ…

Does plasticity enhance or dampen phenotypic parallelism? A test with three lake–stream stickleback pairs Open
Parallel (and convergent) phenotypic variation is most often studied in the wild, where it is difficult to disentangle genetic vs. environmentally induced effects. As a result, the potential contributions of phenotypic plasticity to parall…
