Factors affecting the prey preferences of jackals (Canidae) [PDF]
Mammalian Biology, 2017 Prey selection by carnivores can be affected by top-down and bottom-up factors. For example, large carnivores may facilitate food resources for mesocarnivores by providing\ud carcasses to scavenge, however mesocarnivores may hunt large prey themselves, and their diets might be affected by prey size and behaviour.

The importance of predator behaviour on risk to prey [PDF]
, 2008 Both predator and prey have evolved to maximise reproductive success by balancing food intake with risk. There has been a bias in predator-prey studies, where prey behaviour has been examined in detail, yet predators are assumed to follow simplistic ...

Ratio-independent prey preferences by an estuarine mysid
Journal of Plankton Research, 2020 Abstract The present study quantified prey preferences by adult males and females of the mysid Mesopodopsis wooldridgei fed the calanoid copepods Pseudodiaptomus hessei and Paracartia longipatella at varying proportions. Both sexes of M.

Claw loss and the prey preferences of an invasive crayfish [PDF]
NeoBiotaPredator-prey relationships underpin the stability of ecosystems but can be perturbed by numerous factors, such as biological invasions. Crayfish readily colonize new ecosystems and their impacts can modify food webs or ecosystem functioning.

Poison frog dietary preference depends on prey type and alkaloid load.
PLoS ONE, 2022 The ability to acquire chemical defenses through the diet has evolved across several major taxa. Chemically defended organisms may need to balance chemical defense acquisition and nutritional quality of prey items.

An objective approach to determining the weight ranges of prey preferred by and accessible to the five large African carnivores. [PDF]
PLoS ONE, 2014 Broad-scale models describing predator prey preferences serve as useful departure points for understanding predator-prey interactions at finer scales.

Do lions Panthera leo actively select prey or do prey preferences simply reflect chance responses via evolutionary adaptations to optimal foraging? [PDF]
PLoS ONE, 2011 Research on coursing predators has revealed that actions throughout the predatory behavioral sequence (using encounter rate, hunting rate, and kill rate as proxy measures of decisions) drive observed prey preferences.

Diversity, 2022 Niche partitioning studies are essential to understand the mechanisms that allow ecologically similar species to coexist. The Rhone streber (Zingel asper) and the European bullhead (Cottus gobio) are both benthic riverine fishes that consume ...

Prey Switching with a Linear Preference Trade-Off [PDF]
SIAM Journal on Applied Dynamical Systems, 2014 In ecology, prey switching refers to a predator's adaptive change of habitat or diet in response to prey abundance. In this paper, we study piecewise-smooth models of predator-prey interactions with a linear trade-off in a predator's prey preference. We consider optimally foraging predators and derive a model for a 1 predator-2 prey interaction with a ...

Diet of Eastern Imperial Eagle (Aquila heliaca) in Bulgaria: composition, distribution and variation [PDF]
Biodiversity Data Journal, 2022 The Eastern Imperial Eagle (EIE) is a top predator exploiting different prey in different parts of its distribution. In this study, we summarise data collected over a long period of time (for 25 consecutive years), identifying key prey species in the ...
