Nest Ecology and Prey Preference of the Mud Dauber Wasp Sceliphron formosum (Hymenoptera: Sphecidae) [PDF]
(1) Background: Sceliphron is a genus of sphecid wasps that build mud nests for reproduction. These wasps prey exclusively on spiders, and commonly inhabit human constructions.

Prey preferences of the chimpanzee (Pan troglodytes) [PDF]
The common chimpanzee Pan troglodytes is the closest extant relative of modern humans and is often used as a model organism to help understand prehistoric human behavior and ecology. Originally presumed herbivorous, chimpanzees have been observed hunting

Prey preference in a kleptoplastic dinoflagellate is linked to photosynthetic performance. [PDF]
Abstract Dinoflagellates of the family Kryptoperidiniaceae, known as “dinotoms”, possess diatom-derived endosymbionts and contain individuals at three successive evolutionary stages: a transiently maintained kleptoplastic stage; a stage containing multiple permanently maintained diatom endosymbionts; and a further permanent stage ...

Prey preference follows phylogeny: evolutionary dietary patterns within the marine gastropod group Cladobranchia (Gastropoda: Heterobranchia: Nudibranchia) [PDF]
Background The impact of predator-prey interactions on the evolution of many marine invertebrates is poorly understood. Since barriers to genetic exchange are less obvious in the marine realm than in terrestrial or freshwater systems, non-allopatric ...

Differential Responses of the Ant Odontoponera transversa to Termite Chemical Signals: Evidence for Prey Preference [PDF]
Predators can exploit chemical signals of social insects to locate prey. Ants are considered as major predators of termites, and the interactions between them have been shaped by a long evolutionary history.

Convergence between a mosquito-eating predator's natural diet and its prey-choice behaviour [PDF]
On the basis of 1115 records of Evarcha culicivora feeding in the field, we can characterize this East African jumping spider (Salticidae) as being distinctively stenophagic. We can also, on the basis of laboratory prey-choice experiments, characterize E.

Preference and prey switching in a generalist predator attacking local and invasive alien pests. [PDF]
Invasive pest species may strongly affect biotic interactions in agro-ecosystems. The ability of generalist predators to prey on new invasive pests may result in drastic changes in the population dynamics of local pest species owing to predator-mediated ...

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

Prey Switching with a Linear Preference Trade-Off [PDF]
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 ...

A method to predict overall food preferences.
Most natural ecosystems contain animals feeding on many different types of food, but it is difficult to predict what will be eaten when food availabilities change. We present a method that estimates food preference over many study sites, even when number
