Aquaculture Environment Interactions, 2023 Selecting optimal locations for mussel farming is vital for the optimization of production yield and for the minimization of environmental impact. Although predation by sea ducks may induce large stock losses and hence severe economic loss for mussel ...

Predation drives complex eco-evolutionary dynamics in sexually selected traits.
PLoS Biology, 2023 Predation plays a role in preventing the evolution of ever more complicated sexual displays, because such displays often increase an individual's predation risk.

Reciprocal intraguild predation and predator coexistence [PDF]
Ecology and Evolution, 2018 AbstractIntraguild predation is a mix of competition and predation and occurs when one species feeds on another species that uses similar resources. Theory predicts that intraguild predation hampers coexistence of species involved, but it is common in nature.

Predators avoiding predation [PDF]
Proceedings of the National Academy of Sciences, 2008 The notion of stealthy predation often invokes images of a predator hiding and waiting to ambush its unsuspecting prey. In this issue of PNAS, Manicom et al. (1) offer an alternative reason why predators hide that involves an important tradeoff between capturing prey and seeking refuge to avoid their own demise from other predator species.

Generalist predators disrupt parasitoid aphid control by direct and coincidental intraguild predation [PDF]
, 2011 Generalist predators and parasitoids are considered to be important regulators of aphids. The former not only feed on these pests, but might also consume parasitoids at all stages of development.

Downstream Economic Implications of Predation in the South African Red Meat Industry
Frontiers in Sustainability, 2022 Globally, predation is an important and ongoing problem facing the livestock sector. This study estimated the downstream economic impact of predation in the South African red meat industry using a recent South African Social Accounting Matrix (SAM) and a

UNSUCCESSFUL PREDATION AND LEARNING OF PREDATOR CUES BY CRAYFISH [PDF]
Journal of Crustacean Biology, 2003 Abstract The effect of latent inhibition on learning about cues related to increased predation risk was studied in a native crayfish, Orconectes virilis, and in an invasive species, Orconectes rusticus. Individuals of both species either were exposed or not exposed to the conditioned stimulus (potential “predator” odor = goldfish odor) prior to ...

The trade-off between starvation and predation risk in overwintering redshanks (Tringa totanus) [PDF]
, 2010 In order to meet their energy budget animals must often increase their risk of predation, either through their choice of foraging location or by decreasing anti-predation behaviours, which are incompatible with foraging.

High trees increase sunflower seed predation by birds in an agricultural landscape of Israel
Frontiers in Ecology and Evolution, 2014 Natural habitats in agricultural landscapes promote agro-ecosystem services but little is known about negative effects (dis-services) derived by natural habitats such as crop seed predation.

Biological Reviews, 2020 ABSTRACTCamouflage – adaptations that prevent detection and/or recognition – is a key example of evolution by natural selection, making it a primary focus in evolutionary ecology and animal behaviour. Most work has focused on camouflage as an anti‐predator adaptation. However, predators also display specific colours, patterns and behaviours that reduce
