Previous experiments have shown that for a specific experimental system of guppies (Poecilia reticulata), per capita growth rate is linearly related to population biomass. A length—specific population model is developed to examine how the various mechanisms of density dependence (i.e., changes in somatic growth rates, reproductive rates, and cannibalism) act in concert to shape the overall population response to intraspecific competition. Despite many nonlinear components, equilibrium per…

TLDR
It is concluded that population regulation, density dependence, resource and interference competition, the effects of environmental stress and the form of the ecological niche, are all best defined and analysed in terms of population growth rate.
Experimental evidence for density-dependent responses to mortality of snake-necked turtles
TLDR
It is shown that this species can rebound rapidly following reductions in density, and so is resilient to harvest and predation by pigs, and that high sub-adult and adult survival is crucial for achieving long-term population stability in freshwater turtles generally.
Density-Dependent Effects and the Regulation of Crucian Carp Populations in Single-Species Ponds
TLDR
Density dependence has a variety of regulatory effects on pond populations of crucian carp that contribute to their persistence and resilience, and an increase in relative body depth can be induced in crucians by the presence of piscivorous fish, reducing vulnerability to predation.
Trends in vital rates of the European eel: Evidence for density dependence?
TLDR
Density-dependent processes, such as competition for limited food and space, and trade-offs between reproductive success and survival provide a parsimonious nation (though not one the authors could test for these shifts in population parameters).
IMPLICATIONS OF NON‐LINEAR DENSITY DEPENDENCE
TLDR
Ranges of the ratio of maximum net productivity level (MNPL) to carrying capacity (K) are explored in general models for pinnipeds and odontocetes to demonstrate the range of MNPL/K for marine mammals as a group is large.
JOINT EFFECTS OF POPULATION DENSITY AND TOXICANT EXPOSURE ON POPULATION DYNAMICS OF CAPITELLA SP. I
TLDR
Examination of the combined effects of population density and a toxicant (fluoranthene) on population growth rate and carrying capacity using the deposit-feeding polychaete Capitella sp.
VARIATION IN THE DEMOGRAPHY OF GUPPY POPULATIONS:THE IMPORTANCE OF PREDATION AND LIFE HISTORIES
TLDR
Results from an individual-based computer model suggest that fecundity, offspring size, and individual growth rates were most influential in producing interlocality differences in size distributions and the proportions of the populations that were immature.
How environmental stress affects density dependence and carrying capacity in a marine copepod
TLDR
The results show that a stressor's effects at high population density may differ from its effects at low density, and emphasizes the importance of finding new protocols, such as those introduced here, with which to study the joint effects of a Stressor and population density.
When Shape Matters: Using a Simple Mathematical Model to Estimate Critical Area Sizes in Conservation
In the analysis of anthropogenic impact on the environment arises the question of whether the shapes of preserved habitat fragments play an important role in the conservation of wild species. In

Density‐Dependent Aspects of Growth and Metamorphosis in Bufo Americanus
TLDR
The mean size at metamorphosis was significantly decreased as the initial density of either Bufo or Rana palustris was increased, and this outcome is interpreted as the result of the effect of density on the growth rate of larvae.
Curvilinear Density Dependence and the Design of Field Experiments on Zooplankton Competition
TLDR
A re-analysis of Smith and Cooper's data is presented that more clearly illustrates that curvilinear responses of r to density can occur among zooplankton populations under near-natural conditions, and the effect of resource-renewal techniques on the interpretation of results from competition experiments is discussed.
Asymmetries in population growth regulated by intraspecific competition: Empirical studies and model tests
TLDR
Two simple models are shown to account for asymmetric patterns of population growth for 27 species of Drosophila and for a variety of other organisms, where the data were derived from the literature, to aid laboratory and field ecologists to anticipate the dynamics of various experimental organisms.
Interaction of food level and exploitation in experimental fish populations.
TLDR
Nine populations of ~uppies (Lebistes reticulatus) were established in separate aquariums and measurement of the effeet of expillitntion on stocks of fish led to relatively stable yields during weeks 59 to 72, after initial declines due to readjustment of populations.

TLDR
This model represents an extension of the Lotka-Volterra model of competition; it adds a fourth parameter that controls the degree of nonlinearity in intraspecific growth regulation and represents a similar Extension of the logistic model of population growth.
Competition Among Cladocera
TLDR
In situ enclosure experiments were used to asses the importance of competition to the population dynamics of three cladocerans in a small pond, and the data suggested that the degree of competition was dependent on resource levels and the age of competitors.
An Experimental Test of the Effects of Predation Risk on Habitat Use in Fish
TLDR
Methods to predict the additional mortality expected on a cohort due to a reduction in growth rate are developed, and the potential for predation risk to enforce size—class segregation is discussed, which leads de facto to resource partitioning.
Nonlinearities in competitive interactions component variables or system response
TLDR
Two examples, one drawn from the laboratory and one from the field, contrast the responses of Daphnia brood size and per capita growth rate during density manipulations, caution against inferences about population change based on knowledge of single component variables.
