In some situations the logistic equation in the usual expression, dN/dt=r(1−N/K)N, exhibits properties that are biologically unrealistic. For example, whenr≦0 the population can no longer show any normal, negative response in per-capita growth rate to increasing density. Also, when the equation is employed in the Volterra's competition model, a familiar but incredible conclusion is derived which says that the outcome of competition is entirely independent of the reproductive potentialr of each… Expand

The perfect mixing paradox and the logistic equation: Verhulst vs. Lotka
A theoretical analysis of density-dependent population dynamics in two patches sheds novel light on our understanding of basic ecological parameters. Firstly, as already highlighted in theExpand
Heterogeneous 'proportionality constants' - A challenge to Taylor's Power Law for temporal fluctuations in abundance.
It is shown that the slope of the log-linear relationship (b) is a function of the among-population (co)variation in r and the carrying-capacity, and that local environmental stochasticity is sufficient to generate the full range of observed values of b. Expand
A simple and bounded model of population dynamics for mutualistic networks
This work introduces a model for the population dynamics in mutualism inspired by the logistic equation but cured of divergences and suggests that the model dynamics are rich and may be used to gain further insights in the dynamics of mutualistic interactions. Expand
A lottery model of density-dependent selection in evolutionary genetics
Fitness is typically represented in heavily simplified terms in evolutionary genetics, often using constant selection coefficients, to make it easier to infer or predict how type frequencies changeExpand
A Fundamental Principle Governing Populations
Proposed here is that an overriding principle of nature governs all population behavior; that a single tenet drives the many regimes observed in nature—exponential-like growth, saturated growth,Expand
A law of nature
The principle from which the equation is derived is this: the effect on the environment of a population’s success is to alter that environment in a way that opposes the success. Expand
Dynamic population models are based on the Verhulst's equation (logisitic equation), where the classic Malthusian growth rate is damped by intraspecific competition terms. Mainstream populationExpand
Density-dependent selection in evolutionary genetics: a lottery model of Grime’s triangle
A new model of density-dependent selection which revolves around territorial contests is developed, which generalize the classic lottery model of territorial acquisition to accommodate arbitrary densities and provides a mathematical underpinning for Grime’s verbal scheme. Expand
Is dispersal always beneficial to carrying capacity? New insights from the multi-patch logistic equation.
The conditions under which fragmentation associated to dispersal is either beneficial or detrimental to total population abundance are delineated and it is shown that, depending on the underlying mechanism, there is no unique way to generalize the logistic model to a patchy situation. Expand
The struggle for existence. How the notion of carrying capacity, K, obscures the links between demography, Darwinian evolution and speciation
Widespread use of r-K (‘carrying capacity’) models of population growth appears to have catalysed fundamental discords in ecology, and between ecology and evolution. Expand


Aggregation pattern of individuals and the outcomes of competition within and between species: Differential equation models

These models provide a simplest theoretical basis to explain why many insect populations in nature are kept relatively rare in number and why a number of allied species often coexist freely sharing the same resource, against the “competitive exclusion principle” deduced from the original Volterra equations. Expand
Resource limited and equilibrium models of populations
It is argued that although the two models used as the basis of two distinct models of population dynamics are very different, the distinction between them has been obscured by the use of the same terminology for the parameters of both. Expand

The unsuitability of the logistic equation as a model of population decline is discussed, a simple, more general alternative is suggested, and the difference between Lotka's original development and the more usual derivation based on the concept of carrying capacity is considered. Expand
Ecology: Individuals, Populations and Communities
This new edition contains two new chapters both of which consider areas of applied ecology which are relevant to contemporary global issues, and considers the control of abundance. Expand
Interspecific competition: a new approach to the classical theory
The biological consequences of the classical theory of competition are shown to be at least partly a function of a very special way of interpreting particular constants in simple equations. Ii isExpand
Ancient DNA from the First European Farmers in 7500-Year-Old Neolithic Sites
It is found that 25% of the Neolithic farmers had one characteristic mtDNA type and that this type formerly was widespread among Neolithic Farmers in Central Europe and this finding lends weight to a proposed Paleolithic ancestry for modern Europeans. Expand
Competition between laboratory populations of green leafhoppers,Nephotettix spp. (Homoptera: Cicadellidae)
Temperature differentially affected the outcome of competition between two Nephotettix species and conformed fairly well to those predicted by theLotka-Volterra model using demographic parameters specified for each species. Expand
