Multiple Allee effects and population management

L Berec, E Angulo, F Courchamp - Trends in Ecology & Evolution, 2007 - cell.com
Allee effects, strongly related to the extinction vulnerability of populations and gradually
becoming acknowledged by both theoretically oriented and applied ecologists, have already …

Hunting cooperation and Allee effects in predators

MT Alves, FM Hilker - Journal of theoretical biology, 2017 - Elsevier
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 …

The evidence for Allee effects

AM Kramer, B Dennis, AM Liebhold, JM Drake - Population Ecology, 2009 - Springer
Allee effects are an important dynamic phenomenon believed to be manifested in several
population processes, notably extinction and invasion. Though widely cited in these …

A prey-predator fractional order model with fear effect and group defense

M Das, GP Samanta - International Journal of Dynamics and Control, 2021 - Springer
In this work, a fractional-order prey-predator system with fear effect of predator on prey
population and group defense has been proposed. The existence and uniqueness of the …

Double Allee effects and extinction in the island fox

E Angulo, GW Roemer, L Berec… - Conservation …, 2007 - Wiley Online Library
An Allee effect (AE) occurs in populations when individuals suffer a decrease in fitness at
low densities. If a fitness component is reduced (component AE), per capita population …

How predator functional responses and Allee effects in prey affect the paradox of enrichment and population collapses

DS Boukal, MW Sabelis, L Berec - Theoretical Population Biology, 2007 - Elsevier
In Rosenzweig–MacArthur models of predator–prey dynamics, Allee effects in prey usually
destabilize interior equilibria and can suppress or enhance limit cycles typical of the paradox …

Importance of the Allee effect for reintroductions

A Deredec, F Courchamp - Ecoscience, 2007 - Taylor & Francis
Many factors, both biotic and abiotic, impede the success of reintroductions. Among these is
the difficulty that small populations have in surviving and thriving. For many species of …

Trade-offs in activity budget in an alpine ungulate: contrasting lactating and nonlactating females

S Hamel, SD Côté - Animal Behaviour, 2008 - Elsevier
Optimal time allocation to foraging behaviour may be constrained by intrinsic and extrinsic
factors forcing animals to adopt compromises to meet their daily energetic needs. Our goal …

Density‐dependent habitat selection alters drivers of population distribution in northern Yellowstone elk

BJ Smith, DR MacNulty, DR Stahler, DW Smith… - Ecology …, 2023 - Wiley Online Library
Although it is well established that density dependence drives changes in organismal
abundance over time, relatively little is known about how density dependence affects …

A Michaelis–Menten predator–prey model with strong Allee effect and disease in prey incorporating prey refuge

S Saha, A Maiti, GP Samanta - International Journal of Bifurcation …, 2018 - World Scientific
Here, we have proposed a predator–prey model with Michaelis–Menten functional response
and divided the prey population in two subpopulations: susceptible and infected prey …
