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 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 ...

Relative Preference and Localized Food Affect Predator Space Use and Consumption of Incidental Prey. [PDF]
Abundant, localized foods can concentrate predators and their foraging efforts, thus altering both the spatial distribution of predation risk and predator preferences for prey that are encountered incidentally. However, few investigations have quantified

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.

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

Predicting carrying capacity of a large carnivore from prey densities: a new approach [PDF]
Background Large carnivores play a crucial role in maintaining the balance of the ecosystem. Successful conservation initiatives have often led to a huge increase in predators which has often led to negative interactions with humans.

Prey body size mediates the predation risk associated with being "odd" [PDF]
Despite selection pressures on prey animals to maintain phenotypically homogeneous groups, variation in phenotype within animal groups is commonly observed.
