Trophic niche separation in sympatric rocky shore crabs
Journal of the Marine Biological Association of the United Kingdom, 2019AbstractWhere two species occupy the same habitat and similar niches, competition is likely to drive small-scale spatial niche separation or resource partitioning that may not be immediately apparent. A stable isotope approach was used to investigate potential trophic niche separation between co-existing rocky shore crabs in the North-West (NW) Arabian

Trophic Niches and Trophic Adaptations of Prey-Specialized Spiders from the Neotropics: A Guide
2017Spiders are the most diversified group of terrestrial predators. They employ a wide variety of feeding strategies, and exploit several prey types, from invertebrates up to small vertebrates. Many studies on the trophic ecology of spiders have focused on generalist and euryphagous species.

Trophic niche partitioning in symbiotic marine invertebrates
Abstract Fierce competition for food and space underpins coral reefs’ biodiversity - supported by photosymbiotic foundational species. In contrast to other ecosystems, there is scant evidence that competition is mitigated by niche partitioning.Isis Guibert +7 more

Trophic niche drives the evolution of craniofacial shape in Trinidadian guppies
EvolutionAbstract Diverse clades of fishes adapted to feeding on the benthos repeatedly converge on steep craniofacial profiles and shorter, wider heads. But in an incipient radiation, to what extent is this morphological evolution measurable and can we distinguish the relative genetic vs. plastic effects?

Food-Niche and Trophic Relationships among European Owls
Ornis Scandinavica, 1976The study of three western European owl communities revealed the existence of geographical patterns concerning food-niche characteristics of the individual owl species and, consequently, of community composition and structure. Middle and Northern European communities show a close packing of species along the food dimension of the niche; the ways in ...

The amphibians’ trophic niche project
We here present “The Amphibians’ Trophic Niche Project”, a long-term study that aims to shed light on different aspects of the trophic niche of Italian amphibians. The first part of this project involves the use of the not invasive technique of stomach flushing to obtain stomach contents from individuals in the wild. The analysis of stomach contents (e.Enrico Lunghi +9 more

Trophic Relations and Ontogenetic Niche Shifts in Aquatic Ecosystems
1988One of the most pronounced and consistent patterns in freshwater lakes is that the biomasses of producers and consumers increase along a gradient of increased nutrient (phosphorous) loading. For example, phytoplankton biomass is positively correlated with total phosphorus concentration (Stockner and Shortreed 1985 and references therein), as is the ...
