Trophic Ecology of Damselfi shes
2016Resources (e.g., food and habitat) partitioning may be viewed as one of the key factors in the diversifying process, promoting the coexistence of closely related and ecologically equivalent species (Colwell and Fuentes 1975). The trophic niche is defi ned as the place of an organism in the environment in relation to its food (Silvertown 2004 ...

Abstract Trophic interactions are at the core of several key ecological processes and theories as they determine the flow of material and energy within and across communities and habitats. Odonates provide a rich and diverse taxonomic group with several features (e.g.

Dung beetle trophic ecology: are we misunderstanding resources attraction?
Ecological Entomology, 2020Trophic ecology of dung beetles has been widely studied because of the important ecological role of these taxa. However, previous studies have focused on a limited number of potential food items (mainly vertebrate dung and carrion) and have used only one

As researchers try to predict the effects of human modification at all trophic levels and mediate the impact of rapid environmental change, it has become clear it is no longer a matter of agreeing that both bottom-up and top-down forces play important roles in diverse ecosystems.

Regurgitalites – a window into the trophic ecology of fossil cephalopods
Journal of the Geological Society, 2019Fossil oral ejecta that exclusively contain bivalved calcitic lower jaws of ammonites (=aptychi) from Late Jurassic Solnhofen-type deposits of southern Germany are described.

Towards a multi‐trophic extension of metacommunity ecology
Ecology Letters, 2018Abstract Metacommunity theory provides an understanding of how spatial processes determine the structure and function of communities at local and regional scales. Although metacommunity theory has considered trophic dynamics in the past, it has been performed idiosyncratically with a wide selection of possible dynamics.

Mercury Sources and Trophic Ecology for Hawaiian Bottomfish
Environmental Science & Technology, 2015In Hawaii, some of the most important commercial and recreational fishes comprise an assemblage of lutjanids and carangids called bottomfish. Despite their importance, we know little about their trophic ecology or where the mercury (Hg) that ultimately resides in their tissue originates.

Number of trophic levels in ecological communities
Nature, 1977ECOLOGICAL food chains are typically short, consisting of not more than four or five trophic levels. This is usually explained by a reduction in the energy which is available to successive links in the food chain1,2. In contrast, we believe that the number of trophic levels is constrained by population dynamics and not by ecological energetics.
