Winter mortality has been documented in a large number of freshwater fish populations, and
a smaller, but increasing, number of marine and estuarine fishes. The impacted populations …

Environmental factors influencing parents or offspring during embryogenesis can have
knock-on effects at later life stages of the offspring. These effects may prepare the progeny …

Patterns of phenotypic change across environmental gradients (eg, latitude, altitude) have
long captivated the interest of evolutionary ecologists. The pattern and magnitude of …

Phenotypic variation in morphological characters like body shape or meristic count has long
been used to delineate stocks of fish. It is now well known that there may be both …

Some overharvested fish populations fail to recover even after considerable reductions in
fishing pressure. The reasons are unclear but may involve genetic changes in life history …

Knowledge of geographic and temporal scales of adaptive genetic variation is crucial to
species conservation, yet understanding of these phenomena, particularly in marine …

Latitudinal populations of the Atlantic silverside, Menidia menidia, show substantial genetic
variation in rates of energy acquistion and allocation. Reared in common environments …

Abstract The Atlantic silverside (Menidia menidia) exhibits countergradient latitudinal
variation in somatic growth rate along the East Coast of North America. Larvae and juveniles …

Several recent studies have demonstrated that rapid growth early in life leads to decreased
physiological performance. Nearly all involved experiments over short time periods (< 1 day) …

Aim To explore variation in the number of vertebrae in fishes in the context of Jordan's rule
and other ecogeographical rules. Location Global. Methods The study is based on literature …
