Prey selection along a predators' body size gradient evidences the role of different trait-based mechanisms in food web organization. [PDF]
PLoS ONE, 2023 An increase in prey richness, prey size and predator trophic position with predator body size has been consistently reported as prime features of food web organization. These trends have been explained by non-exclusive mechanisms.

Prey Selection of Scandinavian Wolves: Single Large or Several Small? [PDF]
PLoS ONE, 2016 Research on large predator-prey interactions are often limited to the predators' primary prey, with the potential for prey switching in systems with multiple ungulate species rarely investigated.

Prey selection by an apex predator: the importance of sampling uncertainty. [PDF]
PLoS ONE, 2012 The impact of predation on prey populations has long been a focus of ecologists, but a firm understanding of the factors influencing prey selection, a key predictor of that impact, remains elusive.

Selective Predation of a Stalking Predator on Ungulate Prey. [PDF]
PLoS ONE, 2016 Prey selection is a key factor shaping animal populations and evolutionary dynamics. An optimal forager should target prey that offers the highest benefits in terms of energy content at the lowest costs.

Prey selection based on predator/prey weight ratios for common fishes of Northwest Arabian Gulf [PDF]
Acta Ichthyologica et Piscatoria, 1995 As part of a comprehensive study concerning the trophic interrelationship of fish assemblage in the Northwest Arabian Gulf the characteristic ratios of predator-prey weights for 12 common species were calculated.

Ontogenetic dietary shifts and food selection of endemic Squalius carolitertii (Actinopterygii: Cypriniformes: Cyprinidae) in River Tormes, Central Spain, in summer [PDF]
Acta Ichthyologica et Piscatoria, 2012 Background. The northern Iberian chub Squalius carolitertii (Doadrio, 1988) is a small endemic cyprinid inhabiting the rivers of the Iberian Peninsula. The knowledge of feeding patterns is essential to understand the ecological role of fish populations ...
