Composition and toxicity of venom produced by araneophagous white-tailed spiders (Lamponidae: Lampona sp.)

Scientific Reports, 2022
Prey-specialised spiders are adapted to capture specific prey items, including dangerous prey. The venoms of specialists are often prey-specific and less complex than those of generalists, but their venom composition has not been studied in detail. Here,

Functional Characteristics of Nematocysts Found on the Scyphomedusa Cyanea Capillata [PDF]

, 2007
Although prey capture by cnidarians is mediated through nematocysts, their influence on prey selection by cnidarians remains poorly documented. The difficulty in visualizing nematocyst–prey interactions remains the chief obstacle to understanding how the

The quality of aphids as food for generalist predators: implications for natural control of aphids

European Journal of Entomology, 2005
The paper reviews existing data on the food quality of cereal aphids for generalist predators. Data are presented for spiders, harvestmen, carabid and staphylinid beetles, cockroaches, ants and one species of bird.

Cost-effective and efficient factitious prey for mass production of Neoseiulus cucumeris (Acari: Phytoseiidae): assessing its quality compared with natural prey

Egyptian Journal of Biological Pest Control, 2022
Background Using alternative diets for the mass production of phytoseiid predatory mites may facilitate their cost-effective rearing. Factitious prey is often used as an alternative food source for mass rearing of generalist phytoseiids.

Ladybird-Mediated Indirect Interactions between Two Aphid Species When Using a Banker Plant System

Agronomy, 2022
Banker plant systems have the advantages of introducing natural enemies preventively and maintaining by providing alternative prey, thus controlling the pests sustainably.

Seabirds mediate intraguild and competitive interactions in a shark community

Ecosphere
Intraguild predation (IGP) and competition significantly influence resource utilization patterns among sympatric species. The presence of alternative prey (consumed only by intraguild [IG] predators and not IG prey) may promote coexistence and have a ...

Prey Switching and Natural Pest Control Potential of Carabid Communities over the Winter Wheat Cropping Season

Insects
To date, evaluating the diets of natural enemies like carabids has largely been limited to spatially explicit and short-term sampling. This leaves a knowledge gap for the intra-annual dynamics of carabid diets, and the provision and timing of delivery of

Implications of shared predation for space use in two sympatric leporids

Ecology and Evolution, 2019
Spatial variation in habitat riskiness has a major influence on the predator–prey space race. However, the outcome of this race can be modulated if prey shares enemies with fellow prey (i.e., another prey species).

Calf/female ratio and population dynamics of wild forest reindeer in relation to wolf and moose abundances in a managed European ecosystem.

PLoS ONE, 2021
BackgroundThe alternative prey hypothesis describes the mechanism for apparent competition whereby the mortality of the secondary prey species increases (and population size decreases decreases) by the increased predation by the shared predator if the ...

Sex-biased parental care and sexual size dimorphism in a provisioning arthropod [PDF]

, 2015
The diverse selection pressures driving the evolution of sexual size dimorphism (SSD) have long been debated. While the balance between fecundity selection and sexual selection has received much attention, explanations based on sex-specific ecology have ...
