Trophic levels of Tidal and Non-Tidal Marshes of Southern Mesopotamia
Maǧallaẗ al-baṣraẗ al-ʻulūm al-zirāʻiyyaẗ, 2020 Carlson’s Trophic State Index (CTSI) was applied to assess the trophic status of two kind of southern Mesopotima marshes. Six stations were selected, three in non-tidal Chebiyesh marshes and other three in tidal East Hammer marsh.

Evaluation of Sustainable Utilization of African Marine Fishery Resources
Fishes, 2022 Sustainable utilization evaluation is the basis for ensuring the sustainable exploitation of fisheries’ resources. This paper explores the changes in the mean trophic level of African marine fish catches during a 70-year period based on the statistical ...

Trophic Ecology of Deep-Sea Megafauna in the Ultra-Oligotrophic Southeastern Mediterranean Sea
Frontiers in Marine Science, 2022 The trophic ecology of fourteen species of demersal fishes and six species of demersal decapod crustaceans from the continental slope and rise of the Southeastern Mediterranean Sea (SEMS) was examined using stable isotope analysis. Mean δ13C values among

Estimating Trophic Levels and Trophic Magnification Factors Using Bayesian Inference [PDF]
Environmental Science & Technology, 2013 Food web biomagnification is increasingly assessed by estimating trophic magnification factors (TMF) where solvent (often lipid) normalized contaminant concentration is regressed onto the trophic level, and TMFs are represented by the slope of the relationship.

Can biomass distribution across trophic levels predict trophic cascades? [PDF]
Ecology Letters, 2020 Abstract The biomass distribution across trophic levels (biomass pyramid) and cascading responses to perturbations (trophic cascades) are archetypal representatives of the interconnected set of static and dynamical properties of food chains.

Trophic interactions of meso- and macrozooplankton and fish in the Iceland Sea as evaluated by fatty acid and stable isotope analysis [PDF]
, 2012 A trophic study was carried out in August of 2007 and 2008 on the pelagic ecosystem in the Subarctic Iceland Sea. Carbon and nitrogen stable isotopes and fatty acid biomarkers were used to study trophic linkages and the trophic ecology of the most ...

Dual stable isotope abundances unravel trophic position of estuarine nematodes [PDF]
, 2005 The role and quantitative importance of free-living nematodes in marine and estuarine soft sediments remain enigmatic for lack of empirical evidence on the feeding habits and trophic position of most nematode species.

Bioaccumulation modelling and sensitivity analysis for discovering key players in contaminated food webs: the case study of PCBs in the Adriatic Sea [PDF]
, 2015 Modelling bioaccumulation processes at the food web level is the main step to analyse the effects of pollutants at the global ecosystem level. A crucial question is understanding which species play a key role in the trophic transfer of contaminants to ...
