TLDR
For example, the consumption of a small fish by a larger one entails all the following characteristics: behavioral interplay during pursuit and capture, an instantaneous reduction of the prey population, greater reproductive potential for the predator, a flux of organic energy, and a transfer of mineral nutrients such as phosphorus and nitrogen as mentioned in this paper.Abstract:
here is no common currency for ecological interactions. For example, the consumption of a small fish by a larger one entails all the following characteristics: behavioral interplay during pursuit and capture, an instantaneous reduction of the prey population, greater reproductive potential for the predator, a flux of organic energy, and a transfer of mineral nutrients such as phosphorus and nitrogen. Thus the same event is viewed differ-read more

The Keystone-Species Concept in Ecology and ConservationManagement and policy must explicitly consider the complexity of interactions in natural systems
TL;DR: The term keystone species has enjoyed an enduring popularity in the ecological literature since its introduction by Robert T. Paine in 1969 and it is implicit that these species are exceptional, relative to the rest of the community, in their importance.

TL;DR: In this article, the authors developed an integrative framework for understanding the impact of detritus on food web dynamics, emphasizing the ontogeny and heterogeneity of detribus and the various ways that explicit inclusion of the detrital dynamics alters generalizations about the structure and functioning of food webs.

Are trophic cascades all wet? differentiation and donor-control in speciose ecosystems'
TL;DR: The premise is that true trophic cascades in the community sense are a relatively unusual sort of food web mechanics, and evidence is that these cascades are restricted to fairly low-diversity places where great influence can issue from one or a few species.

Food webs : linkage, interaction strength and community infrastructure
TL;DR: It seems particularly opportune to discuss food webs and evolving views on their structure here for both their genesis and first modern treatment (Elton 1927) and much of their later development (May 1973; Pimm & Lawton 1978) has a decidedly British accent.

TL;DR: Food web effects and abiotic factors were equally potent regulators of primary production in these experiments, illustrating the effects of climatic factors and the natural dynamics of unmanipulated food web interactions.

TL;DR: It is indicated that in Brier Creek, biotic interactions strongly influence the pool-to-pool distributions of Campostoma and algae, par- ticularly during long periods of constant low discharge.
