Atheriniform fishes have recently emerged as attractive models for evolutionary, ecological,
and molecular/physiological studies on sex determination. Many species in this group have …

As temperature-dependent sex determination (TSD) and homozygote or heterozygote
genetic sex determination (GSD) exist in multiple reptilian taxa, they represent sex …

Most of the world's living marine resources inhabit coastal environments, where average
thermal conditions change predictably with latitude. These coastal latitudinal temperature …

Human exposure to the neurotoxic methylmercury (MeHg) occurs primarily via the
consumption of marine fish, but the processes underlying large-scale spatial variations in …

California Grunion Leuresthes tenuis, a beach spawning marine teleost, was described from
a specimen purchased at a San Francisco market in 1859, but not subsequently seen there …

Coastal marine Gasterosteus aculeatus were captured from seven locations along the
Pacific coast of North America, ranging across 21· 8° latitude to test Jordan's rule, ie that …

Variation in the vertebral number of the puyen grande Galaxias platei was examined for
specimens from 22 localities that span the entire distribution range of the species (from 40° …

Across a broad diversity of freshwater and marine fish that have wide latitudinal distributions,
intraspecific variability in vertebral number shows a robust trend for higher vertebral counts …

Body shape and meristic characters are highly variable phenotypic aspects in fish, and in
most cases are related to phylogeography, environmental factors and life history patterns …

ABSTRACT A quantification of intraspecific variation in morphological traits is necessary not
only as a basis for taxonomic work but also to understand a basic aspect of evolution …
