TLDR
The Allee effect can be regarded not only as a suite of problems associated with rarity, but also as the basis of animal sociality.Abstract:Â
Warder C. Allee brought attention to the possibility of a positive relationship between aspects of fitness and population size 50 years ago. Until recently, however, this concept was generally regarded as an intriguing but relatively unimportant aspect of population ecology. Increasing appreciation that Allee effects must be incorporated into models of population dynamics and habitat use, together with recent interest in the implications of sociality for conservation, have shown that for ecology and conservation the consequences of the Allee effect are profound. The Allee effect can be regarded not only as a suite of problems associated with rarity, but also as the basis of animal sociality.read more

Inverse density dependence and the Allee effect
TL;DR: The Allee effect describes a scenario in which populations at low numbers are affected by a positive relationship between population growth rate and density, which increases their likelihood of extinction.

TL;DR: It seems that although rabies viruses have the potential for rapid evolution, this property alone is not enough to overcome genetic barriers, which inhibit the onward transmission of rabies virus into a new species.

Limits to the adaptive potential of small populations
TL;DR: This work states that individuals in small populations have lower fitness owing to environmental stress and genetic problems such as inbreeding, which can substantially increase the extinction probability of populations in changing environments.

Sources, Sinks, and Population Regulation
TL;DR: If the surplus population of the source is large and the per capita deficit in the sink is small, only a small fraction of the total population will occur in areas where local reproduction is sufficient to compensate for local mortality, and the realized niche may be larger than the fundamental niche.

TL;DR: In this paper, natural selection and life histories are modeled in behavioural ecology evolution of life histories human behavioural ecology, and exploitation of resources is discussed in terms of competition for resources interactions between predators and prey.

On the Relationship between Abundance and Distribution of Species
TL;DR: The general relationships between abundance and distribution developed here eventually should contribute to the understanding of the biogeography, population genetics, and evolution of species as well as the ecological attributes of populations and communities.

Populations in a Seasonal Environment.
TL;DR: Fretwell as discussed by the authors analyzed the highly complex interaction between a population and a regularly varying environment in an attempt to define and measure seasonality as a critical parameter in the general theory of population regulation.
