Accelerating rates of environmental change and the continued loss of global biodiversity
threaten functions and services delivered by ecosystems. Much ecosystem monitoring and …

If habitat destruction or overexploitation of populations is severe, species loss can occur
directly and abruptly. Yet the final descent to extinction is often driven by synergistic …

Allee effects are (broadly) defined as a decline in individual fitness at low population size or
density. They can result in critical population thresholds below which populations crash to …

Cooperation is a ubiquitous behavior in many biological systems and is well-known for
promoting Allee effects. However, few studies have paid attention to mechanisms inducing …

In the present, ecologists generally consider the interactions, which are directly related to the
density effects, that species have on each other, like predation, mutualism, refuge, etc …

During the establishment phase of a biological invasion, population dynamics are strongly
influenced by Allee effects and stochastic dynamics, both of which may lead to extinction of …

Allee effects are an important dynamic phenomenon believed to be manifested in several
population processes, notably extinction and invasion. Though widely cited in these …

Garrett Hardin's tragedy of the commons is an analogy that shows how individuals driven by
self-interest can end up destroying the resource upon which they all depend. The proposed …

Allee effect that refers to a positive relationship between individual fitness and population
density provides an important conceptual framework in conservation biology. While …

In 1983 to 1984, a mass mortality event caused a Caribbean-wide,> 95% population
reduction of the echinoid grazer, Diadema antillarum. This led to blooms of algae …
