Third Fork Creek is a historically impaired urban stream that flows through the city of Durham, North Carolina. Caenorhabditis elegans (C. elegans) are non-parasitic, soil and aquatic dwelling nematodes that have been used frequently as a biological and ecotoxicity model. We hypothesize that exposure to Third Fork Creek surface water will inhibit the growth and chemotaxis of C. elegans.Nematodes are often found in highest numbers in the root zone of the crop towards the end of the growing season or in late summer to midwinter. - For Root-knot Nematode on grapevines, juveniles were found in one study to peak in soil in winter, and then to decline in spring as they entered roots. Numbers decline in weedfree, - fallow ground. Soil should …To test these hypotheses, we assessed (1) the large-scale distribution pattern of soil nematodes; (2) the effects of latitude on soil nematode abundance and ecological indexes; (3) the effects of climate factors on soil nematode abundance and community composition; and (4) the distribution of soil nematodes across different vegetation types. 2.
