The hermaphroditic nematode Caenorhabditis elegans has been one of the primary model
systems in biology since the 1970s, but only within the last two decades has this nematode …

Experimental evolution provides a powerful manipulative tool for probing evolutionary
process and mechanism. As this approach to hypothesis testing has taken purchase in …

The nematode Caenorhabditis elegans reproduces primarily by self-fertilization of
hermaphrodites, yet males are present at low frequencies in natural populations …

The nematode Caenorhabditis briggsae is an emerging model organism that allows
evolutionary comparisons with C. elegans and exploration of its own unique biological …

Caenorhabditis elegans can reproduce exclusively by self-fertilization. Yet, males can be
maintained in laboratory populations, a phenomenon that continues to puzzle biologists. In …

Recent research has filled many gaps about Caenorhabditis natural history, simultaneously
exposing how much remains to be discovered. This awareness now provides means of …

The process of speciation is key to the origins of biodiversity, and yet the Caenorhabditis
nematode model system has contributed little to this topic. Genetic studies of speciation in …

The nematode Caenorhabditis elegans is well known to practising biologists as a model
organism. Early work with C. elegans is best understood as part of a descriptive tradition in …

Caenorhabditis elegans is an androdioecious nematode with both hermaphrodites and
males. Although males can potentially play an important role in avoiding inbreeding and …

The evolution of breeding systems results from the existence of genetic variation and
selective forces favoring different outcrossing rates. In this study we determine the extent of …
