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.

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

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.

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

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.

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. Bifurcation analysis is done with respect to predator’s searching rate and handling time.

Effects of Corcyra cephalonica Egg Consumption on Population Fitness and Reproduction of the Whitefly Predator Serangium japonicum (Coleoptera: Coccinellidae) [PDF]
InsectsLadybird beetle, Serangium japonicum (Coleoptera: Coccinellidae), is an important predatory natural enemy of whiteflies, and its mass rearing is crucial for biological control.

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.
