An assessment of the trophic structure of the Bay of Biscay continental shelf food web: Comparing estimates derived from an ecosystem model and isotopic data [PDF]
, 2013 Comparing outputs of ecosystem models with estimates derived from experimental and observational approaches is important in creating valuable feedback for model construction, analyses and validation.

Understanding patterns and processes in models of trophic cascades [PDF]
, 2013 Climate fluctuations and human exploitation are causing global changes in nutrient enrichment of terrestrial and aquatic ecosystems and declining abundances of apex predators. The resulting trophic cascades have had profound effects on food webs, leading

TROPHIC CIRCULATION IN ECOSYSTEMS
Ecosistemas y Recursos Agropecuarios, 2016 The trophic aspect of ecology has been studied for more than six decades; in this contribution we address theoretical aspects relative to the concept of trophic ow at the ecosystem level and from the thermodynamics point of view.

Do trophic subsidies affect the outcome of introductions of a non-native freshwater fish? [PDF]
, 2013 Understanding how environmental variables and human disturbances influence the outcomes of introductions of non-native freshwater fish is integral to their risk management. This can be complex in freshwater ecosystems that receive subsidies that increase

Coupling low and high trophic levels models: Towards a pathways-orientated approach for end-to-end models [PDF]
, 2009 Existing models of marine ecosystems address specific issues related to the bottom-up forcing of production or to the top-down effects of fishing on a limited range of the trophic spectrum.

Food Web Trophic Structure at Marine Ranch Sites off the East Coast of Korea
Frontiers in Marine Science, 2021 Understanding the trophic ecology of the giant Pacific octopus Enteroctopus dofleini is challenging in developing marine ranches and in reestablishing its regional stocks against the severe stress of fishing. We adopted carbon and nitrogen stable isotope

Determining trophic niche width: a novel approach using stable isotope analysis [PDF]
, 2004 1. Although conceptually robust, it has proven difficult to find practical measures of niche width that are simple to obtain, yet provide an adequate descriptor of the ecological position of the population examined. 2.

Beyond the fish-Daphnia paradigm: testing the potential for pygmy backswimmers (Neoplea striola) to cause trophic cascades in subtropical ponds [PDF]
PeerJ, 2022 Trophic cascades, or indirect effects of predators on non-adjacent lower trophic levels, are a classic phenomenon in ecology, and are thought to be strongest in aquatic ecosystems.

Dietary breadth and trophic position of introduced European catfish Silurus glanis in the River Tarn (Garonne River basin), southwest France [PDF]
, 2010 Although being a widely introduced and successfully established species, the European catfish Silurus glanis L. (the world’s third largest freshwater fish) remains poorly studied in its introduced areas.
