ABSTRACT A behavioral syndrome is a suite of correlated behaviors expressed either
within a given behavioral context (eg, correlations between foraging behaviors in different …

Natriuretic peptides are a family of three structurally related hormone/paracrine factors. Atrial
natriuretic peptide (ANP) and B-type natriuretic peptide (BNP) are secreted from the cardiac …

Life-history traits or “fitness components”—such as age and size at maturity, fecundity and
fertility, age-specific rates of survival, and life span—are the major phenotypic determinants …

Natural isolates of C. elegans exhibit either solitary or social feeding behavior. Solitary
foragers move slowly on a bacterial lawn and disperse across it, while social foragers move …

Leptokurtic distributions of movement distances observed in field-release studies, in which
some individuals move long distances while most remain at or near their release point, are a …

A behavioural syndrome occurs when individuals behave in a consistent way through time
or across contexts and is analogous to 'personality'or 'temperament'. Interest is accumulating …

Genes are understandably crucial to physiology, morphology and biochemistry, but the idea
of genes contributing to individual differences in behaviour once seemed outrageous …

Naturally occuring polymorphisms in behavior are difficult to map genetically and thus are
refractory to molecular characterization. An exception is the foraging gene (for), a gene that …

▪ Abstract This review focuses on five key evolutionary issues pertaining to animal cognition,
defined as the neuronal processes concerned with the acquisition, retention, and use of …

Genes can affect natural behavioral variation in different ways. Allelic variation causes
alternative behavioral phenotypes, whereas changes in gene expression can influence the …
