The paper by Hairston et al. (1960) is examined critically with regard to its premises, logic and internal consistency, and its methodology. It is suggested that, either as conclusions or hypotheses, the major points made in the paper are not acceptable. In the present paper the importance of testability and of operational definitions in ecological hypotheses are stressed. 

The "Balance of Nature" and "Population Control"

TLDR
The thesis of Hairston, Smith, and Slobodkin that populations of producers, carnivores, and decomposers are limited by their respective resources in the classical density-dependent fashion is based on a series of assumptions about these trophic levels which are, in all probability, false.

Testing models of trophic dynamics: The problem of translating from model to nature

TLDR
The authors reviewed tests of a particular model, the exploitation ecosystem hypothesis as it was formulated in Oksanen et al. (1981), to study problems that may be encountered when testing models.

Food chain dynamics: the central theory of ecology?

TLDR
This research program, called Food Chain Dynamics, is extended to include the field of community ecology, and arguments are offered defending the position that this research program could be regarded as the central theory of ecology, at least as important as the theory of evolution.

A Metaphysiological Approach to Modeling Ecological Populations and Communities

Modern theoretical ecology owes much to the modeling legacies of Vito Volterra, Alfred Lotka, and Georgii F. Gause. In 1949, Hutchinson and Deevey (1949) acknowledged their contribution by writing

The Nature of Defense: Coevolutionary Studies, Ecological Interaction, and the Evolution of 'Natural Insecticides,' 1959-1983

TLDR
This dissertation aims to provide a history of science and technology in the United States from the perspective of the 20th Century to the present day, with a focus on the industrial revolution and its consequences.

Food web patterns in ecosystems: a reply to Fretwell and Oksanen

TLDR
I review the theoretical and empirical evidence for various theories concerning biomass and turnover patterns of different trophic levels in ecosystems, with special reference to aquatic food webs, and it is concluded that the food chain dynamics theory is useful for examining the direct and indirect effects of predator-prey interactions.

Lindeman's Contradiction and the Trophic Structure of Ecosystems

TLDR
Network analyses of energy-flow models make possible an objective and unamibiguous definition of trophic level that does not suffer this contradiction in L.R. Lindeman's empirical based generalizations.

Experimental tests of trophic dynamics: towards a more penetrating approach

TLDR
An approach to the study of trophic dynamics involving the aggregation of organisms into functional groups, direct quantitative measurements of Trophic processes using field manipulations, inferences based upon the use of field probes and synthesis of ecosystems in closed microcosms are recommended.

Probably the most important conclusion of modern epistemology is that there are no truths or absolutes; thus no theory can give us total certainty, no science is beyond improvement. A scientist

Community Structure, Population Control, and Competition

TLDR
Populations of producers, carnivores, and decomposers are limited by their respective resources in the classical density-dependent fashion and interspecific competition must necessarily exist among the members of each of these three trophic levels.

POPULATION PROCESSES IN THE VOLE AND THEIR RELEVANCE TO GENERAL THEORY

TLDR
According to field evidence the individuals in a declining vole population are intrinsically less viable than their predecessors, and changes in the severity of their external mortality factors are insufficient to account for the increased probability of death.

Studies on the Organization of Animal Communities

TLDR
It is concluded that competition for resources exists among decomposers, among producers, and among carnivores in terrestrial communities.

The Regulation of Density in a Natural Population of the Pond Snail, Lymnaea Elodes

TLDR
The regulation of density in the pond snail was far more complete and occurred more rapidly than was thought possible, and the data strongly suggest that it was mediated through food limitation as expressed in fecundity.
