The nematode Caenorhabditis elegans and diverse potential invertebrate vectors predominantly interact opportunistically

Abstract: Some small animals migrate with the help of other, more mobile animals (phoresy) to leave short-lived and resource-poor habitats. The nematode Caenorhabditis elegans lives in ephemeral habitats such as compost, but has also been found associated with various potential invertebrate vectors. Little research has been done to determine if C. elegans is directly attracted to these invertebrates. To determine whether C. elegans is attracted to compounds and volatile odorants of invertebrates, we conducted chemotaxis… Show more

“…Nematodes also lack the evolutionarily conserved cryptochrome (CRY) proteins [28,53], key in transducing photic inputs to the Drosophila circadian clock [54] and for circadian transcriptional repression in mammals [55,56]. C. elegans' natural ecology (and thus its exposure to daily environmental cycles) is also not well-understood, with populations having been isolated from various surface level and subterranean environments [57][58][59][60][61]. It exhibits a boom-and-bust life cycle, including periods of fast population growth and inactivity; individuals are frequently isolated as dauers [58], a metabolically less active, stress-resistant and diapause state entered into when population density, food availability or temperature conditions become unfavourable [62,63].…”
