Spatiotemporal predictions of the alternative prey hypothesis: Predator habitat use during decreasing prey abundance

open access: yesEcosphere, 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.

Predation risk is a function of alternative prey availability rather than predator abundance in a tropical savanna woodland ecosystem. [PDF]

open access: yesSci 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.

The effect of the alternative prey, Paramecium caudatum (Peniculida: Parameciidae), on the predation of Culex pipiens (Diptera: Culicidae) by the copepods Macrocyclops albidus and Megacyclops viridis (Cyclopoida: Cyclopidae) [PDF]

open access: yesJournal of medical entomology, 2018
Biological control can be an effective tool to combat public health risks associated with mosquito-borne disease. However, target impacts of biological control agents may be reduced by biotic contexts such as the presence of alternative prey.

Alternative prey use affects helminth parasite infections in grey wolves. [PDF]

open access: yesJournal of Animal Ecology, 2016
Summary Predators affect prey populations not only through direct predation, but also by acting as definitive hosts for their parasites and completing parasite life cycles. Understanding the affects of parasitism on prey population dynamics requires knowing how their predators’ parasite community is affected by diet and prey availability.

Effects of Corcyra cephalonica Egg Consumption on Population Fitness and Reproduction of the Whitefly Predator Serangium japonicum (Coleoptera: Coccinellidae) [PDF]

open access: yesInsects
Ladybird 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]

open access: yesInsects
In 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.

Habitat selection when killing primary versus alternative prey species supports prey specialization in an apex predator [PDF]

open access: yesJournal of Zoology, 2019
© 2019 The Zoological Society of London Many predators specialize on one or several prey species that they select from the range of potential prey. Predator specialization on primary versus alternative prey is driven in part by encounter rates with prey ...

Alternative Prey and Artificial Diet of the Multicolored Asian Lady Beetle Harmonia axyridis: A Review [PDF]

open access: yesInsects
As an important natural enemy insect, Harmonia axyridis has significant biological control effects on a variety of pests such as aphids in agroforestry ecosystems. The large-scale application of H. axyridis has long been limited by the unstable supply of

Productivity of Neoseiulus bicaudus (Acari: Phytoseiidae) Reared on Natural Prey, Alternative Prey, and Artificial Diet

open access: yesJournal of Economic Entomology, 2019
The predatory mite, Neoseiulus bicaudus (Wainstein), is a potential biological control agent against spider mites and thrips. The objective of this experiment was to compare the effects of three diets on the life table of N. bicaudus.

FUNCTIONAL RESPONSES: A QUESTION OF ALTERNATIVE PREY AND PREDATOR DENSITY [PDF]

open access: yesEcology, 2007
Throughout the study of ecology, there has been a growing realization that indirect effects among species cause complexity in food webs. Understanding and predicting the behavior of ecosystems consequently depends on our ability to identify indirect effects and their mechanisms.
