Patterns observed for meiobenthic nematodes were compared with those from larger-sized benthic fauna. Correlation analyses of nematode populations with the varied substrate occurring in the study area revealed that locations with similar sediment type and water depth were also most similar faunistically. The combined analysis of different faunal groups showed a notable similarity between species distribution patterns and this was partly based on common affinities for particular habitat conditions. The influence of factors related to sediment granulometry generally decreased with increasing size and mobility of the faunal group investigated. In terms of diversity and species composition, nematode communities encountered were similar to those occurring in comparable environments worldwide. As evident from sediment, contaminant and faunal analyses, acute effects of human activities on nematode populations seem unlikely. (c) 2005 Elsevier B.V.

Like shallow waters, deeper waters are increasingly subject to a range of anthropogenic disturbances, which can lead to significant alterations in sedimentation patterns. These alterations often exceed naturally occurring changes. We used a combined analysis of six independent data sets arising from large-scale field surveys and small-scale laboratory experiments to investigate the effects of seabed disturbance on nematode communities. Disturbance response was documented as a function of disturbance type (coastal development, dredged material disposal, bottom trawling, glacial fjord) and intensity (low, medium, high). Natural and man-induced seabed disturbance exerted differential effects on exposed populations, generating changes in the taxonomic (genus) and functional (feeding type) attributes of their assemblages. The genus composition of nematode assemblages from geographically separate seas converged with increased level of various types of man-made disturbance. Assemblages present along a gradient of natural disturbance in a glacial fjord followed an opposite response vector, suggesting that community changes induced by anthropogenic activities, or experimental treatments simulating the principal impacts of these, inherently differ from disturbance of natural origin. Changes in trophic diversity and structure were primarily driven by factors confounded with physical disturbance, such as metal contamination. Coupling the results of analyses at multiple scales proved a useful means of providing deeper insights into the general response of ecological communities to environmental change.1 aSchratzberger, M1 aLampadariou, N.1 aSomerfield, P., J.1 aVandepitte, L.1 aBerghe, Vanden  uhttps://nematoda.myspecies.info/content/impact-seabed-disturbance-nematode-communities-linking-field-and-laboratory-observations00524nas a2200121   4500008004100000245010100041210006900142300001400211490000800225100002100233700002000254856012800274       1998                        eng d00aEffects of Physical Disturbance On Nematode Communities in Sand and Mud - a Microcosm Experiment0 aEffects of Physical Disturbance On Nematode Communities in Sand   a643–6500 v1301 aSchratzberger, M1 aWarwick, R., M.  uhttps://nematoda.myspecies.info/content/effects-physical-disturbance-nematode-communities-sand-and-mud-microcosm-experiment
