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 …

Social and solitary feeding in natural Caenorhabditis elegans isolates are associated with
two alleles of the orphan G-protein-coupled receptor (GPCR) NPR-1: social feeders contain …

Wild isolates of Caenorhabditis elegans can feed either alone or in groups,. This natural
variation in behaviour is associated with a single residue difference in NPR-1, a predicted G …

Natural variations of wild Caenorhabditis elegans isolates having either Phe-215 or Val-215
in NPR-1, a putative orphan neuropeptide Y-like G protein-coupled receptor, result in either" …

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 …

Variation in food quality and abundance requires animals to decide whether to stay on a
poor food patch or leave in search of better food. An important question in behavioral …

Wild isolates of Caenorhabditis elegans differ in their tendency to aggregate on food [1, 2].
Most quantitative variation in this behavior is explained by a polymorphism at a single amino …

Animals modify food-seeking behavior and metabolism according to perceived food
availability. Here we show that, in the roundworm C. elegans, release of neuropeptides from …

The nematode C. elegans is an important model for the study of social behaviors. Recent
investigations have shown that a family of small molecule signals, the ascarosides, controls …

Adjusting to a continuously changing environment is a key feature of life. For metazoans,
environmental changes include alterations in the gut microbiota, which can affect both …
