... or vibration. Here, we tested the hypothesis that the nematode worm Caenorhabditis elegans exhibits a behavioural response to vibration that is distinct from its responses to touch. We show that wild-type strain worms respond to sustained low-frequency vibration in a manner distinct from the known responses...

...Tess Renahan; Ray L. Hong ABSTRACT Nematode–insect interactions are ubiquitous, complex and constantly changing as the host and nematode coevolve. The entomophilic nematode Pristionchus pacificus is found on a myriad beetle species worldwide, although the molecular dynamics of this relationship...

...Yuya Kiyama; Kohji Miyahara; Yasumi Ohshima SUMMARY Feeding and food choice are crucial to the survival of an animal. The nematode Caenorhabditis elegans feeds on various microorganisms in nature, and is usually fed Escherichia coli in the laboratory. To elucidate the mechanisms of food/non-food...

... that this nematode and its natural bacterial associate can penetrate, kill and reproduce in an insect host and that the bacterial associate can induce this insect pathogenic life cycle in other Caenorhabditis species, including C. elegans . Our findings suggest that this life history may be widespread in nature...

...David A. Wharton SUMMARY A technique for determining the internal osmotic concentration of a small nematode using a modified nanolitre osmometer is described and used to investigate osmoregulation in the Antarctic nematode Panagrolaimus davidi . This technique enables the osmotic concentration...

...Jeremie Korta; Damon A. Clark; Christopher V. Gabel; L. Mahadevan; Aravinthan D. T. Samuel SUMMARY Animals move through their environments by selecting gaits that are adapted to the physical nature of their surroundings. The nematode Caenorhabditis elegans swims through fluids or crawls on surfaces...

...Jing-Tzyh Alan Chiang; Mark Steciuk; Boris Shtonda; Leon Avery SUMMARY To explore the use of Caenorhabditis elegans and related nematodes for studying behavioral evolution, we conducted a comparative study of pharyngeal behaviors and neuronal regulation in free-living soil nematodes. The pharynx...

...Adam J. Shannon; John A. Browne; Jacqueline Boyd; David A. Fitzpatrick; Ann M. Burnell SUMMARY Members of the genus Panagrolaimus are bacterial-feeding nematodes that occupy a diversity of niches ranging from Antarctic and temperate soils to terrestrial mosses. Some members of this genus are able...

...David A. Wharton; Gordon Goodall; Craig J. Marshall SUMMARY The relative importance of freezing tolerance and cryoprotective dehydration in the Antarctic nematode Panagrolaimus davidi has been investigated. If nucleation of the medium is initiated at a high subzero temperature (-1°C), the nematodes...
