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.

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.

Plant toxins and parasitoid trophic ecology
Current Opinion in Insect Science, 2019Parasitoids (parasitic wasps) are ubiquitous components of nearly all communities containing plant-insect herbivore associations. Plant toxin defenses against herbivores may also affect higher trophic levels by directly (e.g., plant toxins encountered in host hemolymph) or indirectly (e.g., plant toxins reduce host size/quality or alter the host's ...

The Trophic‐Dynamic Aspect of Ecology
Ecology, 1942Recent progress in the study of aquatic food-cycle relationships invites a reappraisal of certain ecological tenets. Quantitative productivity data provide a basis for enunciating certain trophic principles, which, when applied to a series of successional stages, shed new light on the dynamics of ecological succession.

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.

Trophic Ecology and Plant/Herbivore Energetics
1982The objective of this chapter is to summarize and discuss the state of our knowledge of energy flows through the aboveground plant and herbivore compartments at Nylsvley. At the outset, it is stressed that there are as yet too few data for anything more than a superficial analysis.
