PLoS ONE, 2023 An increase in prey richness, prey size and predator trophic position with predator body size has been consistently reported as prime features of food web organization. These trends have been explained by non-exclusive mechanisms.

Journal of Limnology, 2022 Food web studies rely heavily on the use of traditional gut content analysis or the fairly popular stable isotope analysis rather than fatty acid analysis (FAA) despite its straightforward process, and ability to identify and characterize more diverse ...

Crop Domestication and Its Impact on Naturally Selected Trophic Interactions
Annual Review of Entomology, 2015 Crop domestication is the process of artificially selecting plants to increase their suitability to human requirements: taste, yield, storage, and cultivation practices. There is increasing evidence that crop domestication can profoundly alter interactions among plants, herbivores, and their natural enemies.

Trophic coherence determines food-web stability [PDF]
, 2014 Why are large, complex ecosystems stable? Both theory and simulations of current models predict the onset of instability with growing size and complexity, so for decades it has been conjectured that ecosystems must have some unidentified structural ...

Feeding on multiple sources: towards a universal parameterization of the functional response of a generalist predator allowing for switching. [PDF]
PLoS ONE, 2013 Understanding of complex trophic interactions in ecosystems requires correct descriptions of the rate at which predators consume a variety of different prey species.

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.

Trophic structure in a seabird host-parasite food web: insights from stable isotope analyses [PDF]
, 2010 Ecological studies on food webs rarely include parasites, partly due to the complexity and dimensionality of host-parasite interaction networks. Multiple co-occurring parasites can show different feeding strategies and thus lead to complex and cryptic ...

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 ...

Food composition of some low altitude Lissotriton montandoni (Amphibia, Caudata) populations from North-Western Romania [PDF]
Archives of Biological Sciences, 2010 The diet of some populations of Lissotriton montandoni from north-western Romania is composed of prey belonging to 20 categories. The food components of the Carpathian newts are similar to those of other species of newts.
