The Invasive Round Goby Neogobius melanostomus as a Potential Threat to Native Crayfish Populations
Animals, 2021 Despite the spread of round goby Neogobius melanostomus into freshwater streams, there is a lack of information with respect to its effect on macroinvertebrate communities, especially crustaceans. We studied foraging efficiency of N.

Preference alters consumptive effects of predators: top-down effects of a native crab on a system of native and introduced prey. [PDF]
PLoS ONE, 2012 Top-down effects of predators in systems depend on the rate at which predators consume prey, and on predator preferences among available prey. In invaded communities, these parameters might be difficult to predict because ecological relationships are ...

Preference for envenomated rodent prey by rattlesnakes [PDF]
Bulletin of the Psychonomic Society, 1978 Adult specimens of several rattlesnake species which struck and envenomated a mouse or which did not have an opportunity to strike were allowed to choose between an envenomated mouse and one manually killed by the experimenter. Only rattlesnakes that struck a mouse made a choice, and the envenomated mouse was selected most frequently.

European Journal of Entomology, 2004 Two-choice experiments on prey preferences of a generalist predator Pterostichus melanarius, and five species of slug prey, were conducted in the laboratory. Different preferences of P. melanarius for each of the slug species are described.

Variation in hunting behaviour in neighbouring chimpanzee communities in the Budongo forest, Uganda.
PLoS ONE, 2017 Hunting and sharing of meat is seen across all chimpanzee sites, with variation in prey preferences, hunting techniques, frequencies, and success rates.

An apparent trade-off between direct and signal-based induced indirect defence against herbivores in willow trees. [PDF]
PLoS ONE, 2012 Signal-based induced indirect defence refers to herbivore-induced production of plant volatiles that attract carnivorous natural enemies of herbivores.

A method to predict overall food preferences.
PLoS ONE, 2022 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

Frontiers in Zoology, 2022 Aeolid nudibranchs are well-known for their ability to incorporate cnidarian nematocysts and use them for defense; this process is tightly linked with the feeding preferences of molluscs.

Prey preference in a kleptoplastic dinoflagellate is linked to photosynthetic performance
The ISME Journal, 2023 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 ...

The Effect of Digestive Capacity on the Intake Rate of Toxic and Non-Toxic Prey in an Ecological Context. [PDF]
PLoS ONE, 2015 Digestive capacity often limits food intake rate in animals. Many species can flexibly adjust digestive organ mass, enabling them to increase intake rate in times of increased energy requirement and/or scarcity of high-quality prey.
