Measurement and quantification of the network indicators requires that an ecosystem level assessment is implemented. The ENA metrics convey the status of the ecological system state variables, and mostly, the flows and relations between the various nodes of the network. The seven metrics are: 1) Average Path Length (APL), 2) Finn Cycling Index (FCI), 3) Mean Trophic level (MTL), 4) Detritivory to Herbivory ratio (D:H), 5) Keystoneness, 6) Structural Information (SI), and 7) Flow-based Information indices. The procedure for calculating each metric is detailed along with a short evaluation of their potential assessment of environmental status. {\textcopyright} 2019 Elsevier Ltd}, keywords = {coastal zone, Cycling, Decision making, ecological approach, Ecological network analysis, ecosystem approach, ecosystem management, Ecosystems, environmental policy, food web, Food webs, Marine and coastal environments, Marine environment, network analysis, policy implementation, stakeholder, Trophic length}, issn = {09645691}, doi = {10.1016/j.ocecoaman.2019.03.007}, url = {https://www.sciencedirect.com/science/article/abs/pii/S0964569118305969}, author = {Fath, B.D. and H Asmus and R.

Investigation of their feeding behavior and trophic position remains challenging due to their small size. In this study, we determine and compare the food sources used by nematodes and benthic copepods by using stable isotope compositions, fatty acid profiles and compound specific isotope analyses of fatty acids in the mudflats, seagrass beds and a sandflat of the Marennes-Ol{\'e}ron Bay, France, and the Sylt-R{\o}m{\o} Bight, Germany. Suspended particulate organic matter was much more 13C-depleted than other food sources and meiofauna, highlighting its poor role in the different studied habitats. The very low proportions of vascular plant fatty acid markers in meiofauna demonstrated that these consumers did not rely on this food source, either fresh or detrital, even in seagrass beds. The combined use of stable isotopes and fatty acids emphasized microphytobenthos and benthic bacteria as the major food sources of nematodes and benthic copepods. Compound specific analyses of a bacteria marker confirmed that bacteria mostly used microphytobenthos as a substrate. {\textcopyright} 2019 Elsevier Ltd}, keywords = {Article, Bacillariophyta, bacteria, bacterium, Benthic copepods, Benthic diatoms, Biological materials, biomarker, Biomass, carbon 13, coastal zone, controlled study, Copepoda, delta carbon 13, delta nitrogen 15, Diatom, Ecosystems, fatty acids, Feeding Behavior, food supply, France, Free livings, Freeze Drying, Frisian Islands, Germany, high performance liquid chromatography, intertidal environment, isotope analysis, Isotopes, lipid composition, Marennes-Oleron Bay, Meiofauna, microbial activity, Microphytobenthos, mudflat, Mudflats, Nematoda, nitrogen 15, nonhuman, North Frisian Islands, Nouvelle-Aquitaine, Organic matter, Phytobenthos, Plants (botany), Sandflats, seagrass, Seagrass beds, Sediment, soft-bottom environment, species habitat, substrate, suspended particulate organic matter, Sylt-Romo Bight, trophic environment, Trophic markers, Trophic structure, unclassified drug}, issn = {01411136}, doi = {10.1016/j.marenvres.2019.05.014}, url = {https://www.sciencedirect.com/science/article/abs/pii/S0141113618304744}, author = {van der Heijden, L.H. and Graeve, M. and R.
