Feeding behaviour of the nauplii of the marine calanoid copepod Paracartia grani Sars: Functional response, prey size spectrum, and effects of the presence of alternative prey. [PDF]
PLoS ONE, 2017 Laboratory feeding experiments were conducted to study the functional response and prey size spectrum of the young naupliar stages of the calanoid copepod Paracartia grani Sars.

The alternative prey hypothesis revisited: Still valid for willow ptarmigan population dynamics. [PDF]
PLoS ONE, 2018 The alternative prey hypothesis predicts that the interaction between generalist predators and their main prey is a major driver of population dynamics of alternative prey species.

Changes in life history traits and transcriptional regulation of Coccinellini ladybirds in using alternative prey [PDF]
BMC Genomics, 2020 Background Ladybird beetles (Coleoptera, Coccinellidae) are highly diverse in their feeding habits. Most of them are specialist feeders, while some can have a broad spectrum of prey.

Indirect effects of primary prey population dynamics on alternative prey [PDF]
Theoretical Population Biology, 2014 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.

Alternative Prey and Predator Interference Mediate Thrips Consumption by Generalists [PDF]
Frontiers 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 ...

Biological mosquito control is affected by alternative prey. [PDF]
Zool Stud, 2015 BackgroundMosquitofish 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

Global stability of predator-prey system with alternative prey. [PDF]
ISRN Biotechnol, 2013 A predator-prey model in presence of alternative prey is proposed. Existence and local stability conditions for interior equilibrium points are derived. Global stability conditions for interior equilibrium points are also found.

Consuming alternative prey does not influence the DNA detectability half-life of pest prey in spider gut contents [PDF]
PeerJ, 2019 Background Key natural enemy-pest interactions can be mapped in agricultural food webs by analysing predator gut content for the presence of a focal pest species.

The resilience of weed seedbank regulation by carabid beetles, at continental scales, to alternative prey. [PDF]
Sci Rep, 2020 Carabids are generalist predators that contribute to the agricultural ecosystem service of seedbank regulation via weed seed predation. To facilitate adoption of this ecosystem services by farmers, knowledge of weed seed predation and the resilience of ...

Alternative prey mediate intraguild predation in the open field.
Pest Management Science, 2022 BACKGROUND Generalist 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
