Blind and depigmented fish belonging to the species Astyanax mexicanus are outstanding
models for evolutionary genetics. During their evolution in the darkness of caves, they have …

Why certain animals lose features believed essential, like eyes, bodily color, and
robustness, to live permanently underground has long intrigued biologists and laymen …

Rudimentary structures are variable, which is most impressively demonstrated by the eyes
and dark body pigmentation of species evolving in caves. As these can often still be crossed …

A recent paper in Molecular Ecology by Jost (2008) seriously questions the merit of the
widely used GST statistic and its derivatives as measures of genetic differentiation. This has …

We investigated replicated ecological speciation in the livebearing fish Poecilia mexicana
and P. sulphuraria (Poeciliidae), which inhabit freshwater habitats and have also colonized …

Divergent natural selection drives evolutionary diversification. It creates phenotypic diversity
by favoring developmental plasticity within populations or genetic differentiation and local …

Sexual harassment by males has been reported from several live-bearing fishes
(Poeciliidae) and has been shown to inflict costs on females. For example, poeciliid females …

Life‐history traits are very sensitive to extreme environmental conditions, because resources
that need to be invested in somatic maintenance cannot be invested in reproduction. Here …

The brain is a plastic organ, and so intraspecific studies that compare results obtained from
wild individuals with those from common‐garden experiments are crucial for studies aiming …

Cystathionine γ-lyase (CSE) is the major enzyme in vascular smooth muscle cells (SMCs)
that catalyzes the endogenous production of H 2 S. Phenotypic switching of SMCs is …
