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

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.

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.

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 ...

Coping with shifting nest predation refuges by European reed Warblers Acrocephalus scirpaceus. [PDF]
PLoS ONE, 2014 Predation, the most important source of nest mortality in altricial birds, has been a subject of numerous studies during past decades. However, the temporal dynamics between changing predation pressures and parental responses remain poorly understood. We

Avian Research, 2022 Nest predation is an essential factor affecting bird population density, reproductive ecology and life cycle. However, there are still contradictory results about how nest predation pressure changes with urbanization.

Factors that influence Cape fur seal predation on Cape gannets at Lambert’s Bay, South Africa [PDF]
PeerJ, 2022 Seabird populations experience predation that can impact their breeding density and breeding success. The Cape gannet Morus capensis is endemic to the Benguela upwelling ecosystem and is classified as Endangered by the IUCN.

Diel timing of nest predation changes across breeding season in a subtropical shorebird
Ecology and Evolution, 2021 Predation is the most common cause of nest failure in birds. While nest predation is relatively well studied in general, our knowledge is unevenly distributed across the globe and taxa, with, for example, limited information on shorebirds breeding in ...

, 2005 Predating predators requires at least three specimen to which we refer as players 1, 2, and 3. Player 1 has simply to guess nature when trying to find food. Player 2 is hunting player 1 in the hope that 1 is well-fed but must also avoid being hunted by player 3.
