Contrasting effects of environment and genetics generate a continuum of parallel evolution
Parallel evolution of similar traits by independent populations in similar environments is
considered strong evidence for adaptation by natural selection. Often, however, replicate …

Genomics of rapid incipient speciation in sympatric threespine stickleback
Ecological speciation is the process by which reproductively isolated populations emerge as
a consequence of divergent natural or ecologically-mediated sexual selection. Most …

[HTML][HTML] Effects of environmental variation on host–parasite interaction in three-spined sticklebacks (Gasterosteus aculeatus)
JP Scharsack, F Franke, NI Erin, A Kuske, J Büscher… - Zoology, 2016 - Elsevier
Recent research provides accumulating evidence that the evolutionary dynamics of host–
parasite adaptations strongly depend on environmental variation. In this context, the three …

Shared and nonshared genomic divergence in parallel ecotypes of Littorina saxatilis at a local scale
Parallel speciation occurs when selection drives repeated, independent adaptive
divergence that reduces gene flow between ecotypes. Classical examples show parallel …

Intercontinental genomic parallelism in multiple three-spined stickleback adaptive radiations
Parallelism, the evolution of similar traits in populations diversifying in similar conditions,
provides strong evidence of adaptation by natural selection. Many studies of parallelism …

How parallel is parallel evolution? A comparative analysis in fishes
Evidence of phenotypic parallelism is often used to infer the deterministic role played by
natural selection. However, variation in the extent or direction of divergence is often evident …

Parallel local adaptation to an alpine environment in Arabidopsis arenosa
Parallel local adaptation, that is, when distinct genetic lineages independently adapt to the
same selective environment, provides strong evidence for the action of natural selection. A …

Adaptive divergence between lake and stream populations of an E ast A frican cichlid fish
Divergent natural selection acting in different habitats may build up barriers to gene flow and
initiate speciation. This speciation continuum can range from weak or no divergence to …

Does plasticity enhance or dampen phenotypic parallelism? A test with three lake–stream stickleback pairs
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 …

Simple modifications of mowing regime promote butterflies in extensively managed meadows: evidence from field-scale experiments
Restoring biodiversity-rich grasslands within cultivated matrices represents a real
conservation challenge. One set of options consists in adopting less disruptive mowing …
