Black sea urchins evaluate predation risk using chemical signals from a predator and injured con- and heterospecific prey
(Inter-research, 2011-01-01)
The traits related to foraging and eating are crucial to our understanding of food webs. The use of signals to detect predators has strong relevance for prey survival. The black sea urchin Echinometra lucunter cohabits ...

The effectiveness of post-contact defenses in a prey with no pre-contact detection
(Urban und Fischer VerlagJena, 2013-06)
Most empirical and theoretical papers on prey–predator interactions are for animals with long-range detection, animals that can detect and react to predators long before these touch the prey. Heavy-bodied and chemically ...
Consuming Costly Prey: Optimal Foraging and the Role of Compensatory Growth
(2021-03-18)
Some prey are exceptionally difficult to digest, and yet even non-specialized animals may consume them—why? Durophagy, the consumption of hard-shelled prey, is thought to require special adaptations for crushing or digesting ...
Influence of Prey Size on the Capture of Social Wasps (Hymenoptera: Vespidae) by the Orb-Web Spider Nephilengys cruentata
(California State University, 2010-01-01)
The objective of the present study was to evaluate the plasticity of the hunting behavior of the spider Nephilengys cruentata (Araneae: Nephilidae) facing different species of social wasps. Considering that wasps can consume ...
Geographic variation in the size of mammalian prey taken by White-tailed Kites in the Americas
(Associação Field Ornithologists, 2004-06-01)
I examined the size of small mammal prey taken by White-tailed Kites (Elanus leucurus) in the Americas from data obtained in the literature and unpublished material from southern Brazil. Mean weight of adult small mammal ...
