Wild Seasons, Urban Stasis: Anthropogenic Food Subsidies Buffer Seasonal Dietary Shifts for Coyotes (Canis latrans) in a Wildland‐Urban Landscape South of Mexico City [PDF]
Ecology and EvolutionCoyote (Canis latrans) populations are expanding into urban areas, yet how their feeding ecology adapts to the wildland–urban interface remains poorly understood, particularly near megacities such as Mexico City.

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 ...

Convergence between a mosquito-eating predator's natural diet and its prey-choice behaviour [PDF]
Royal Society Open Science, 2016 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.

Lions Panthera leo Prefer Killing Certain Cattle Bos taurus Types
Animals, 2020 Lion predation on cattle causes severe human–wildlife conflict that results in retaliatory persecution throughout the lion’s geographic range. Cattle closely resemble the body size, shape, and herding patterns of preferred lion prey species.

Animals, 2023 Conservation strategies for apex predators, like the snow leopard (Panthera uncia), depend on a robust understanding of their dietary preferences, prey abundance, and adaptability to changing ecological conditions.
