Prey limitation drives variation in allometric scaling of predator-prey interactions
(2018-10-01)
Ecologists have long searched for a universal size-scaling constant that governs trophic interactions. Although this is an appealing theoretical concept, predator-prey size ratios (PPSRs) vary strikingly across and within ...
Mechanisms of prey size selecon in a suspension feeding copepod, Temora longicornis
(Inter-research, 2014-12-15)
We examined size-dependent prey detection and prey capture in free-swimming Temora longicornis using video observations, particle image velocimetry (PIV), and bottle incubations with phytoplankton prey sizes within the ...
Stomach fullness modulates prey size choice in the frillfin goby, Bathygobius soporator
(Elsevier Gmbh, Urban & Fischer Verlag, 2012-10-01)
Behaviours related to foraging and feeding in predator-prey systems are fundamental to our understanding of food webs. From the perspective of a predator, the selection of prey size depends upon a number of factors including ...
Predator-prey body size relationship in temporary wetlands: Effect of predatory insects on prey size spectra and survival
(EDP Sciences, 2016-03)
The effect of predators on prey size structure in aquatic communities has been well studied in lentic permanent habits, but less attention has been placed on temporary environments. The biota of seasonal Andean wetlands ...
Energetic cost of predation: Aerobic metabolism during prey ingestion by juvenile rattlesnakes, Crotalus durissus
(1999-06-01)
We investigated the cost of prey ingestion in the South American rattlesnake, Crotalus durissus, to see if the capacity to generate energy aerobically could be a constraint on the size of the prey that can be ingested. To ...

We investigated the cost of prey ingestion in the South American rattlesnake, Crotalus durissus, to see if the capacity to generate energy aerobically could be a constraint on the size of the prey that can be ingested. To ...
Reply to comment: Prey perception in feeding-current feeding copepods
(Amer Soc Limnology Oceanography, 2016-07)
We reply to the comments of Paffenhöfer and Jiang (2016) who argues that remote chemical prey perception is necessary for feeding‐current feeding copepods to fulfill their nutritional requirements in a dilute ocean, that ...
Perceiving the algae: How feeding-current feeding copepods detect their nonmotile prey
(American Society of Limnology and Oceanography, 2015-03)
Feeding-current feeding copepods detect and capture prey individually, but the mechanism by which nonmotile prey is detected has been unclear. Early reports that copepods detect phytoplankton prey at distances of one body ...
On certain new exact solutions of a diffusive predator-prey system
(2013-05-01)
We construct exact solutions for a system of two coupled nonlinear partial differential equations describing the spatio-temporal dynamics of a predator-prey system where the prey per capita growth rate is subject to the ...
