Prey size preference in the tokay gecko (Gekko gecko)
Behaviour, 2023 Abstract The optimal foraging theory posits that animals aim to maximize energy intake while minimizing predation and handling costs during foraging. Most observed animal behaviour supports this theory, but occasional deviations provide insights into the ecological factors that shape foraging decisions. We tested prey-size preference using a two-choice

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.

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 ...

Within-guild dietary discrimination from 3-D textural analysis of tooth microwear in insectivorous mammals [PDF]
, 2013 Resource exploitation and competition for food are important selective pressures in animal evolution. A number of recent investigations have focused on linkages between diversification, trophic morphology and diet in bats, partly because their roosting ...

Females prefer extra-pair males that are older and better hunters [PDF]
, 2015 Age of male is an important cue in mate selection, including extra-pair copulations; different phenotypic and behavioural traits are known to be age related. Paternity studies show that older males predominate as fathers of extra-pair young. It

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.

Assortative Mating By Diet In A Phenotypically Unimodal But Ecologically Variable Population Of Stickleback [PDF]
, 2008 Speciation with gene flow may be driven by a combination of positive assortative mating and disruptive selection, particularly if selection and assortative mating act on the same trait, eliminating recombination between ecotype and mating type ...

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.

Olfactory cue use by three-spined sticklebacks foraging in turbid water: prey detection or prey location? [PDF]
, 2012 Foraging, when senses are limited to olfaction, is composed of two distinct stages: the detection of prey and the location of prey. While specialist olfactory foragers are able to locate prey using olfactory cues alone, this may not be the case for ...
