In summary, then, our general conclusions are: (1) Populations of producers, carnivores, and decomposers are limited by their respective resources in the classical density-dependent fashion. (2) Interspecific competition must necessarily exist among the members of each of these three trophic levels. (3) Herbivores are seldom food-limited, appear most often to be predator-limited, and therefore are not likely to compete for common resources. 

Metacommunity Ecology in a Plant–Herbivore System

TLDR
The results showed that tansy–aphid metacommunity dynamics can be described mostly by the species–sorting perspective and metacomunity structure is influenced strongly by dispersal ability, strength of competitive interactions, availability of mutualistic partners and by the resident predators’ community.

Habitat disturbance modifies dominance, coexistence, and competitive interactions in tropical ant communities

TLDR
Interspecific competition is a major structuring principle in ecological communities and the outcome of competitive interactions is hard to predict, highly context‐dependent, and multiple factors can modulate such interactions.

Relationships of Primary and Secondary Production in Lakes and Marine Ecosystems

TLDR
Interactions of primary and secondary production involve processes that occur in food webs, and it is apparent that both kinds of controls have effects that may be direct, indirect, or interactive.

Salinity cascading and predator effects on consumer and producer community structure: a mesocosm experiment

TLDR
The combined effects of biotic and abiotic factors on primary producers and consumer communities composed of numerous species are observed, and the shape of community structure is often shaped by a combination of bottom‐top and top‐bottom processes.

POPULATION DYNAMICS – THE INFLUENCE OF HERBIVORY

TLDR
There is a continuing need for studies of population dynamics, but there is an urgent requirement for these studies to be related to a unifying conceptual base.

Interaction of Productivity and Consumption

Few areas of food web theory have attracted as much interest as the elucidation of the relative importance of resource limitation and predation in limiting or controlling the various trophic levels

Models with several species and trophic levels

TLDR
This chapter is devoted to a few cases of three species dynamics that illustrate some complexities of multiple species interaction and introduce to the use of some more advanced mathematical technique.

Facilitation versus competition in grazing herbivore assemblages

TLDR
Evidence for facilitation through stimulation of grass regrowth during the growing season appears stronger than that for increased resource access through removal of obstructing grass structures during the dormant season, suggesting seasonal tradeoffs between facilitation and competition.

Spatial heterogeneities in parasitism and population dynamics.

TLDR
It is suggested that more attention should be given to the measurement of the basic reproductive rates of parasitoids, as well as the partitioning of the finite rate of increase of hosts into density dependent and independent contributions.

Interspecies Competition and Its Probable Influence Upon the Vertical Distribution of Appalachian Salamanders of the Genus Plethodon

TLDR
The subject of interspecies competition has recently received an excellent review by Crombie (1947), and no attempt has been made here to give a complete bibliography.

TLDR
This paper is a sequel to one on the ecological aspects of species formation in passerine birds, where it was shown that two species with similar ecology cannot live in the same area, and the extent to which the same might apply in British non-passerine birds was analyzed.
