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.

Influence of Alternative Prey on the Functional Response of a Predator in Two Contexts: With and without Intraguild Predation [PDF]
InsectsIn biological control, joint releases of predators and parasitoids are standard. However, intraguild predation (IGP) can occur when a predator attacks a parasitoid, potentially affecting pest control dynamics.

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.

Alternative Prey and Predator Interference Mediate Thrips Consumption by Generalists
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 ...

Ecosphere, 2023 The alternative prey hypothesis supposes that predators supported by a primary prey species will shift to consume alternative prey during a decrease in primary prey abundance.

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.

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 ...

Predation risk is a function of alternative prey availability rather than predator abundance in a tropical savanna woodland ecosystem. [PDF]
Sci Rep, 2019 Typically, factors influencing predation risk are viewed only from the perspective of predators or prey populations but few studies have examined predation risk in the context of a food web.
