Nematodes are found in all habitats that are at least temporary in contact with water: as parasites they live in animals and plants; many non-parasitic species are inhabitants of sediments of rivers, lakes and the sea or are living in terrestric habitats: e.g. mosses and plant litter. Terrestric species are found in especially high numbers in the pore system of soils. As other microscopic “soil dwellers”, e.g. tardigrades (water bears) and rotifers, a nematode’s active life is bound to water.
The Section works taxonomically with soil-dwelling Nematoda and Tardigrada. Ecological research primarily concerns population dynamics and community ecology of nematodes, as well as interactions with ressources and fauna within the soil food web.
