... and motility are the primary cause of male infertility during moderate heat stress. However, this is not the case in the model nematode Caenorhabditis elegans , where changes in mating behavior are the primary cause of fertility loss. We report that heat-stressed C. elegans males are more motivated to locate...

The use of Caenorhabditis elegans could be an alternative approach to determine the effects of mutations on voltage-gated calcium channel function because all the main types of voltage-gated calcium channels are found in C...

In contrast to reproduction limited by female gametes (Bateman's Principle), self-fertilizing Caenorhabditis elegans hermaphrodites exhibit sperm-limited reproduction. Caenorhabditis elegans hermaphrodites are thought to experience a fitness trade-off between...
