“…In the case of the Venice lagoon this activity is supported by a high net primary production. With respect to this, the mean value of our estimate, to which a high standard deviation is associated, exceeds of 50% the maximum production estimated by Libralato et al (2002), and is 4 times higher than the primary production estimated by Leguerrier et al (2003) for benthic and pelagic systems of the Brouage mudflat (conversion from mass to energy was carried out according to the average phytoplankton caloric content by Platt and Irwin (1973)). …”

“…As one can see, 99% of the total primary production occurs in the benthic sub-system. The key role of benthic producers in the food web of shallow water systems was already discussed by Leguerrier et al (2003) for the Brouage mudflat. These authors estimated a production 5.2 times higher in the benthic system compared to the pelagic one, by considering only productions by phytoplankton and microphytobenthos compartments.…”

IM have been widely used in ecosystem modelling during the last years, as they allow one to consistently estimate a large number of unknown flows from a relatively small number of observations (Leguerrier et al, 2003;Vézina et al, 2004;Savenkoff et al, 2007a,b) concerning standing biomasses, diets and flows.…”

“…Meiofaunal metabolism often exceeds that of macrofauna (Leguerrier et al 2003 and references therein) and therefore has a large impact on the turnover of carbon. In addition, meiobenthic organisms comprise several functional groups and so contribute significantly to food-web complexity (Schmid-Araya et al 2002).…”

Siphonostomatoid copepods are often numerically important at deep-sea hydrothermal vents but their role in vent food webs has been little investigated. We examined food sources of 2 vent copepod species, Stygiopontius quadrispinosus and Benthoxinus spiculifer, and their potential role in the diet of paralvinellid worms, using a combination of complementary techniques: (1) stable carbon and nitrogen isotopes, (2) fatty acid composition and (3) morphological examination of copepod mouth structures using scanning electron microscopy. All 3 techniques revealed distinct differences between the 2 copepod species. Fatty acid composition identified bacteria as the main food source for both copepod species and indicated that S. quadrispinosus may be more specialised than B. spiculifer. Stable carbon and nitrogen isotopes provided further evidence that the 2 species partition food sources but feed at the same trophic level. The fatty acid composition and stable isotopes of both paralvinellid worms showed that they are generalists, with a varied diet. Further, in samples where S. quadrispinosus were highly abundant, both worms had stable carbon and nitrogen isotopic compositions that indicated that they were feeding on copepods. Although neither worm appeared anatomically equipped for seizing live copepod prey, we suggest that dead copepods may be consumed along with other particulate debris by the paralvinellid worms. The contribution of copepod remains to the detrital pool in these mineral substratum habitats remains to be quantified.

The development and maintenance of spatial patterns and the way they affect the dynamics of populations and ecosystems is a key issue in ecology. Since each individual and each species experiences the environment on a unique range of scales, it is vital to determine the spatial scales across which organisms interact with each other and the structuring influence of their environments, which can be achieved by analyzing species' distribution patterns. Here, the spatial variation in the distribution of Scrobicularia plana is described for 4 intertidal areas along the species' distributional range. Spatial autocorrelation correlograms based on Moran's coefficient reveal that while the Trondheim (Norway) population was randomly distributed, at Minho (Portugal), the Westerschelde, and the Wadden Sea (both in The Netherlands) populations were aggregated. Patch diameter varied from 150 to 1250 m, in Minho and Westerschelde, respectively; while in the Wadden Sea, patches of 4 to 10 km were detected. Comparisons of spatial patterns with those of other co-occurring bivalve species (Abra tenuis, Cerastoderma edule, and Macoma balthica) revealed that S. plana's distribution was generally patchier. The distribution of S. plana was correlated with sediment type at Westerschelde and Trondheim, but not Minho. The observed differences in distribution patterns and their correlation with environmental factors reveal that spatial patterns of S. plana are site-specific rather than species-specific.
