Although many studies have examined quantitative trait variation across many species, only
a small number of genes and thereby molecular mechanisms have been discovered …

The global rate of wildlife extinctions is accelerating, and the persistence of many species
requires conservation breeding programs. A central paradigm of these programs is to …

Regulatory variants in gene expression serve as bridges linking genetic variation and
phenotypic plasticity. Environmental conditions typically influence the effects of regulatory …

Distinguishing which traits have evolved under natural selection, as opposed to neutral
evolution, is a major goal of evolutionary biology. Several tests have been proposed to …

Copper is one of a handful of biologically necessary heavy metals that is also a common
environmental pollutant. Under normal conditions, copper ions are required for many key …

Quantitative genetics provides the tools for linking polymorphic loci to trait variation. Linkage
analysis of gene expression is an established and widely applied method, leading to the …

The nematode Caenorhabditis elegans has been a versatile model for understanding the
molecular responses to abiotic stress and pathogens. In particular, the response to heat …

Life history is defined by traits that reflect key components of fitness, especially those relating
to reproduction and survival. Research in life history seeks to unravel the relationships …

Studying genetic variation of gene expression provides a powerful way to unravel the
molecular components underlying complex traits. Expression quantitative trait locus (eQTL) …

Most ectotherms obey the temperature-size rule, meaning they grow larger in a colder
environment. This raises the question of how the interplay between genes and temperature …
