A time dynamic model was used to estimate carbon flows through nematodes in an intertidal benthic ecosystem in the Westerschelde Estuary, The Netherlands. The model calibrated the nematode biomass observed from March 1991 to February 1992. The forcing functions of the model included meiobenthos biomass, macrobenthos biomass, bacterial density, chlorophyll-a concentration, and other abiotic data such as temperature and day length. We estimate that the nematode population had a low level of standing stock 249 mg C m(-2), but a high level of carbon flow. It consumed 98 mg C m(-2) d(-1) and produced 22 mg C m(-2) d(-1). Defecation was 73 mg C m(-2) d(-1). Losses in respiration, excretion and natural death were only 3 mg C m(-2) d(-1). The annual P/B was 32 for... |

Three new Ceramonema species, one new Dasynemoides species and one new Pterygonema species are described from South Africa. Ceramonema algoensis sp. nov. is characterised by more than 300 annules and the elongated cephalic capsule with an elevated lip region; C. africana sp. nov. by an elongated cloacal annule and a long cephalic capsule; and C. kromensis sp. nov. by the absence of vascuolisation and a relatively short cephalic capsule. Dasynemoides tenuis sp. nov. can be distinguished from all other known species of the genus by its slender body (a=118) and the large number of body annules (690). Pterygonema papenkuili sp. nov. is characterised by the shape of the spicules, which have a spine-like structure, and a large and rectangular gubernaculum. |

The objective is to describe the population structure of Comesoma arenae Gerlach, 1956 during a one-year period. The area studied, Coroa Grande, is located in Sepetiba Bay, State of Rio de Janeiro, Brazil. Sampling was carried out monthly, from May 1998 through April 1999. Most individuals in the population were adults, of which non-ovigerous females were the most abundant. The species showed its highest population densities during the colder months. |
