How does a carnivore guild utilise a substantial but unpredictable anthropogenic food source? Scavenging on hunter-shot ungulate carcasses by wild dogs/dingoes, red foxes and feral cats in south-eastern Australia revealed by camera traps.

... Australia, 4 Melbourne Water, Reefton, Victoria, Australia Abstract There is much interest in understanding how anthropogenic food resources subsidise carnivore populations. Carcasses of hunter-shot ungulates are a potentially substantial food source for mammalian carnivores.

Squirrels first ‘‘paw manipulate’’ a food item, holding it loosely in Introduction Food storing allows animals to take advantage of excess food in relation to current demand [1], survive periods of scarcity, and reduce foraging time during future food searches [2]. Because food- storing animals either consume items immediately or ... competing interests exist. * E-mail: current economic climate (e.g., current food abundance and the competition for that food) .

Models of food- storing behavior indicate that an animal’s ability to obtain information about the future value of food can improve food- storing decisions [13]. Assessment of food items before consumption or storage is a common and important behavior in diverse species,

A circadian clock in the olfactory bulb anticipates feeding during food anticipatory activity.

... of Introduction Under daily food restriction many species develop food anticipatory activity (FAA), which is considered a behavioral output of a putative food entrainable oscillator (FEO) [1]. Rather than being found in a single locus, it had been proposed that the FEO is a distributed system of interacting structures [2,3]. During food ingestion several ... after nursing suggest that MOB is important for synchronization when food is present, as not all nuclei related to food intake, e.g. in the brainstem, are synchronized by scheduled meal [21]. But at the same time seems that lack of food also induces PER1 increase, perhaps indicating lack of food to other brain regions, similar to a previous report [21]. ... of the food; one of them is the olfactory system. However, despite the fact that this structure plays an important role during meal ingestion [4], it has received little attention for its possible role in entrainment to cycles of food availability [5,6].

Here, we analyzed asymmetry in handling behavior of pine cones by red squirrels (Sciurus vulgaris).

Hence, the asymmetry in motor patterns we observed in the handling of pine cones by squirrels might be evolved as an adaptation to reduce handling time, increasing feeding efficiency and allowing saving time for other activities.
