A fundamental problem in genome biology is to elucidate the evolutionary forces
responsible for generating nonrandom patterns of genome organization. As the first …

Recombination rate and linkage disequilibrium, the latter a function of population genomic
processes, are the critical parameters for mapping by linkage and association, and their …

Many nematodes show a stage-specific behavior called nictation in which a worm stands on
its tail and waves its head in three dimensions. Here we show that nictation is a dispersal …

Parabens, the alkyl esters of p-hydroxybenzoic acid such as methylparaben (MeP),
ethylparaben (EtP), propylparaben (PrP), butylparaben (BuP) are used as a preservative in …

Nematodes are very common animals and they have repeatedly evolved parasitic lifestyles
during their evolutionary history. Recently, the genomes of many nematodes, especially …

Background The free-living nematode Caenorhabditis elegans is the predominant model
organism in biological research, being used by a huge number of laboratories worldwide …

Background How do very small animals with limited long-distance dispersal abilities move
between locations, especially if they prefer ephemeral micro-habitats that are only available …

Caenorhabditis elegans strains carrying stress-reporter green fluorescent protein
transgenes were used to explore patterns of response to metals. Multiple stress pathways …

We monitored survival and reproduction of 1000 individuals of Caenorhabditis elegans wild
type (N2) and 800 individuals of clk-1 and daf-2, and used biodemographic analysis to …

The temperature sensitivity of the germ line is conserved from nematodes to mammals.
Previous studies in C. briggsae and Drosophila showed that isolates originating from …
