W. C. Allee brought attention to the possibility of a positive relationship between aspects of fitness and population size over fifty years ago. This phenomenon, frequently termed the Allee effect, has been the focus of increased interest over the past two decades in the light of concerns over conservation and the problems of rarity. Use of the term suffers from the absence of a clear definition however, with the result that Allee effects are frequently thought to involve only a narrow range of…

Multiple Allee effects and population

It is suggested that more research is needed to assess the prevalence and interactions of multiple Allee effects, as failing to take them into account could have adverse consequences for the management of threatened or exploited populations.

The evidence for Allee effects

Although there is conclusive evidence for Allee effects due to a variety of mechanisms in natural populations of 59 animal species, it is found that existing data addressing the strength and commonness ofAllee effects across species and populations is limited; evidence for a critical density for most populations is lacking.

The Allee Effect: Its History and Future Importance

Support for the growing relevance of Allee effects to conservation biology as well as population and community dynamics is emphasized and proposals for much new terminology are reviewed and found to be helpful in building mechanistic understanding of the core concept.

MODELS OF ALLEE EFFECTS AND THEIR IMPLICATIONS FOR POPULATION AND COMMUNITY DYNAMICS

Up to now, Allee effects have been examined in the context of most existing model structures, and significantly altered the authors' picture of population and community dynamics based on assuming negative density dependence only.

Variation in Allee effects: evidence, unknowns, and directions forward

This work synthesizes evidence for variation in Allee effects and highlights potential mechanisms, and emphasizes the “Allee slope,” i.e., the magnitude of the positive effect of density on the per-capita growth rate, as a metric for demographic Allee Effects.

Allee Effects in Population Dynamics

The Allee effect may be described as a notion of positive density dependence in which the “overall individual fitness”, or one of its components, is positively related to population size or density.

Allee Effects : Mating and Invasion The evidence for Allee effects

Although there is conclusive evidence for Allee effects due to a variety of mechanisms in natural populations of 59 animal species, it is found that existing data addressing the strength and commonness of Allee effect across species and populations is limited; evidence for a critical density for most populations is lacking.

Review: Allee effects in social species

It is shown that group size heterogeneity and intergroup interactions affect the strength of population-level demographic Allee effects, and this provides a conceptual framework that allows for the integration of differentAllee effects in social species.

Directions in conservation biology

The small-population paradigm has not yet contributed significantly to conserving endangered species in the wild because it treats an erect (smallness) as if it were a cause and hence is of scant theoretical interest.

Allee effect and population dynamics in the Glanville fritillary butterfly

It is shown that emigration rate increases and the fraction of mated females decreases with decreasing local density, and the Allee effect increases the significance of the rescue effect in metapopulations, and thereby the potential for alternative stable states in meetapopulation as well as in local dynamics.

Allee Effects in Metapopulation Dynamics

This work has shown that nontrivial equilibrium p* 5 1 2 (e/m) is globally stable as long as m .

A FRAGMENTED POPULATION IN A VARYING ENVIRONMENT

Abstract When speaking about spatially distributed populations, a conceptual distinction is made between two spatial scales and, hence, between two classes of populations which are termed as “pure”

Population Dynamics of Exploited Fish Stocks at Low Population Levels

Estimates of spawner abundance and number of surviving progeny for 128 fish stocks indicated only 3 stocks with significant depensation, strengthening the conclusion that depensatory dynamics are not apparent for fish populations at the levels studied.

The influence of numbers released on the outcome of attempts to introduce exotic bird species to New Zealand

No significant effects on the probability of successful establishment were apparent for the mean date of release, the minimum number of years in which birds were released, the hemisphere of origin (northern or southern) and the size and diversity of latitudinal distribution of the natural geographical range.

Stability and Complexity in Model Ecosystems played a key role in introducing nonlinear mathematical models, along with the study of deterministic chaos, to ecologists—as science writer James Gleick would chronicle in his best-seller Chaos.

Individual mobility prevents an Allee effect in sparse populations of the bush cricket Metrioptera roeseli: an experimental study

This experimental study shows that individuals can avoid an Allee effect by adjusting their movement behaviour in sparse populations even at a population density of five individuals per hectare, i.e. approximately one percent of normal population densities.

Demographic stochasticity and Allee effect on a scale with isotropic noise

Diffusion models of stochastic population dynamics, including both demographic and environmental stochasticity, can be transformed to a scale with isotropic noise. On this scale, demographic
