Additionally, the influence of wind as a second important stress factor was considered. Six sample sites were chosen, reflecting a gradient of river influence within the broader river mouth area. Nematode communities, varying in a mean range from 121 to 165 ind/10 cm(2), were found to differ significantly in terms of abundance, feeding type composition and species diversity. Deposit feeders were most abundant at all sites followed by chewers. Deposit feeders were affected mainly by wind events, while species diversity and the occurrence of chewers were influenced mainly by river discharge. The impact of both these stress factors was modified by a third variable, water level. Moderate and high levels of combined habitat stress led to significant changes in community structure. Under conditions of calm weather and low discharge, reduced species diversity and an increased predominance of deposit feeders were observed. In most cases, species diversity was found to be higher under moderate stress conditions, an observation that offers support for Connel's Intermediate Disturbance Hypothesis.10adisturbance10adiversity10afeeding types10ahabitat stress10aspatial pattern10atemporal pattern1 aWitthoeft-Muehlmann, A.1 aTraunspurger, W.1 aRothhaupt, K., O.  uhttps://nematoda.myspecies.info/content/combined-influence-river-discharge-and-wind-littoral-nematode-communities-river-mouth-area-l01843nas a2200253   4500008004100000245013000041210006900171260009700240300001200337490000700349520088000356653001901236653001401255653001401269653002601283653002201309100002001331700002001351700001801371700001901389700002401408700002001432856013701452       2007                        eng d00aMorphometry, energetics and diversity of free-living nematodes from coasts of Bizerte lagoon (Tunisia): an ecological meaning0 aMorphometry energetics and diversity of freeliving nematodes fro  aSTATION BIOLOGIQUE PLACE GEORGES TEISSIER, 29680 ROSCOFF, FRANCEbCAHIERS DE BIOLOGIE MARINE  a121-1370 v483 aAnalyses of water quality in the Bizerte lagoon showed their relative low oxygenation during September 2002 compared to December 2001. Sediment variables appeared directly dependent on the silt/clay distribution and sewage from the metallurgic factory "El Fouledh". Nematode abundances were negatively influenced by silt/clay, organic matter, metals and chlorophyll a content. The individual nematode body size was clearly related to the distribution of two dominant species, Terschellingia longicaudata (Linhomoeidae) and Paracomesoma dubium (Comesomatidae). Shannon-Wiener diversity index values were the lowest in the South-Western stations characterized by higher level of organic matter and a weaker effect of pollution, in "Baie des carrieres" and "Menzel Jemil" areas. The sediment metals were the key factors controlling the respiration rate of meiobenthic nematodes.10aBizerte lagoon10abody size10adiversity10ameiobenthic nematodes10arespiration rates1 aBoufahja, Fehmi1 aBeyrem, Hamouda1 aEssid, Naceur1 aAmorri, Jalila1 aMahmoudi, Ezzeddine1 aAissa, Patricia  uhttps://nematoda.myspecies.info/content/morphometry-energetics-and-diversity-free-living-nematodes-coasts-bizerte-lagoon-tunisia-eco
