Indirect effects of primary prey population dynamics on alternative prey [PDF]

open access: yesTheoretical Population Biology, 2015
We develop a theory of generalist predation showing how alternative prey species are affected by changes in both mean abundance and variability (coefficient of variation) of their predator's primary prey. The theory is motivated by the indirect effects of cyclic rodent populations on ground-breeding birds, and developed through progressive analytic ...

Biological mosquito control is affected by alternative prey. [PDF]

open access: yesZool Stud, 2015
AbstractBackgroundMosquitofish were introduced to several countries of the tropics and subtropics as biological agents for the control of mosquito larvae. Meanwhile, they became a threat to native communities and fish worldwide, similar to other invasive species through resource competition, overexploitation, or habitat alteration. We investigated prey

Mathematical and Dynamic Analysis of a Prey‐Predator Model in the Presence of Alternative Prey with Impulsive State Feedback Control [PDF]

open access: yesDiscrete Dynamics in Nature and Society, 2012
The dynamic complexities of a prey‐predator system in the presence of alternative prey with impulsive state feedback control are studied analytically and numerically. By using the analogue of the Poincaré criterion, sufficient conditions for the existence and stability of semitrivial periodic solutions can be obtained.

Alternative prey influence the predation of mosquito larvae by three water bug species (Heteroptera: Nepidae)

open access: yesLimnological Review, 2020
The indirect interactions among multiple prey sharing a common predator characterize apparent competition. In conservation biological control involving mosquitoes and controphic prey against generalist insect predators, apparent competition may be a ...

AN ECO-EPIDEMIOLOGICAL STUDY WITH PARASITE ATTACK AND ALTERNATIVE PREY

open access: yesJournal of Biological Systems, 2009
The present paper deals with the problem of a predator-prey system with disease in the prey population. We observe the dynamics of such a system under the influence of severe as well as unnoticeable parasite attack and also alternative food sources for predator population.

CONTROL OF DISEASE IN PREY POPULATION BY SUPPLYING ALTERNATIVE FOOD TO PREDATOR

open access: yesJournal of Biological Systems, 2014
A simple predator–prey system with disease in prey population and alternative food for the predator is proposed and analyzed. The main objective of the present investigation is to observe the conditions for which the disease in prey population will be controlled.

The importance of predator behaviour on risk to prey [PDF]

open access: yes, 2008
Both predator and prey have evolved to maximise reproductive success by balancing food intake with risk. There has been a bias in predator-prey studies, where prey behaviour has been examined in detail, yet predators are assumed to follow simplistic ...

A Predator-Prey Model With Strong Allee Effect In The Prey And An Alternative Food Source For The Predator

open access: yes, 2016
In this paper, we have studied the dynamical behaviors of a predator-prey model, where the prey is subject to strong Allee effect, and the predator has an alternative food source. Positivity and boundedness of the system are discussed. Some extinction criteria are derived.

Alternative Prey and Predator Interference Mediate Thrips Consumption by Generalists

open access: yesFrontiers in Ecology and Evolution, 2022
Generalist predators’ complex feeding relationships make it difficult to predict their contribution to pest suppression. Alternative prey can either distract predators from attacking pests, weakening biocontrol, or provide food that support larger ...

Alternative prey mediate intraguild predation in the open field

open access: yesPest Management Science, 2022
AbstractBACKGROUNDGeneralist predators that kill and eat other natural enemies can weaken biological control. However, pest suppression can be disrupted even if actual intraguild predation is infrequent, if predators reduce their foraging to lower their risk of being killed.
