T(w)o Patch or Not T(w)o Patch: A Novel Biocontrol Model

Mathematical Methods in the Applied Sciences, Volume 49, Issue 13, Page 14697-14743, 15 September 2026.
ABSTRACT A number of top‐down biocontrol models have been proposed where the introduced predators' efficacy is enhanced via the provision of additional food (AF). However, if the predator has a pest‐dependent monotone functional response, pest extinction is unattainable. In the current manuscript, we propose a model where a predator with pest‐dependent

INVADING PARASITOIDS SUFFER NO ALLEE EFFECT: A MANIPULATIVE FIELD EXPERIMENT

, 2007
International audienceOne frequent explanation for the failure of biological invasions is the Allee effect: due to positive density dependence, initially small invading populations may fail to establish and spread.

Allee Effects in Population Biology

Biomath Communications, 2014
The Allee effect is a phenomenon in biology characterized by a positive correlation between population density (size) and its per capita growth rate. This effect is simply a casual positive relationship between the number of individuals in a population and their overall individual fitness.

Stability analysis of a population dynamics model with Allee effect

, 2007
In this study, we focus on the stability analysis of equilibrium points of population dynamics with delay when the Allee effect occurs at low population density is considered.

Dynamic complexity of a discretized predator-prey system with Allee effect and herd behaviour

Applied Mathematics in Science and Engineering
This paper investigates the dynamics of a discrete-time predator-prey system in which the prey population is impacted by the Allee effect. Possible fixed points in the system are studied for their existence and topological categorization.

Dispersal, Population Growth, and the Allee Effect: Dynamics of the House Finch Invasion of Eastern North America

, 1996
Since about 1940, when they were first released in the new York City area, house finches (Carpodacus mexicanus) have multiplied explosively and colonized much of eastern North America.
