Ecology Letters (2011) 14: 615–624 Abstract Biological invasions are a global and
increasing threat to the function and diversity of ecosystems. Allee effects (positive density …

Eradication is the deliberate elimination of a species from an area. Given that international
quarantine measures can never be 100% effective, surveillance for newly arrived …

Invasive species are increasing in number, extent and impact worldwide. Effective invasion
management has thus become a core socio-ecological challenge. To tackle this challenge …

Although dispersal requires context‐dependent decision‐making in three distinct stages
(emigration, transit, immigration), these decisions are commonly ignored in simple models of …

In this paper, a Leslie–Gower-type model is proposed to study a diffusive predator–prey
system with multiple Allee effects acting on the growth rate of the prey population. Crowley …

Like other animals and plants, insects may find it difficult to survive and reproduce in small
populations, to the extent that their long‐term persistence may be jeopardized. The A llee …

In sexual organisms, low population density can result in mating failures and subsequently
yields a low population growth rate and high chance of extinction. For species that are in …

The harmful effects of insect pests on human health and agricultural output are a major
global concern. Frequent use of chemical pesticides as a means of pest control can have …

Preventing the establishment of invading pest species can be beneficial with respect to
averting future environmental and economic impacts and also in preventing the …

Background Allee effects may arise as the number of individuals decreases, thereby
reducing opportunities for cooperation and constraining individual fitness, which can lead to …
