Like most organisms, the nematode Caenorhabditis elegans relies heavily on
neuropeptidergic signaling. This tiny animal represents a suitable model system to study …

food.•Foraging animals make ethologically relevant and neurally interesting decisions.•In …

The ongoing loss of biodiversity caused by rapid climatic shifts requires accurate models for
predicting species' responses. Despite evidence that evolutionary adaptation could mitigate …

Habitat fragmentation, an important element of current global change, has profound
repercussions on population and species extinction. Landscape fragmentation reduces …

Most heritable behavioral traits have a complex genetic basis, but few multigenic traits are
understood at a molecular level. Here we show that the C. elegans strains N2 and CB4856 …

The mechanistic basis for how genetic variants cause differences in phenotypic traits is often
elusive. We identified a quantitative trait locus in Caenorhabditis elegans that affects three …

Innate behaviours are flexible: they change rapidly in response to transient environmental
conditions, and are modified slowly by changes in the genome. A classical flexible …

Browse recently published articles in most issues of leading journals, and there will be
mention of ''the worm''. What is this worm, why is it so keenly studied by so many, and what …

Random search is a behavioral strategy used by organisms from bacteria to humans to
locate food that is randomly distributed and undetectable at a distance. We investigated this …

Robust biological systems are expected to accumulate cryptic genetic variation that does not
affect the system output in standard conditions yet may play an evolutionary role once …
