Unusual Feeding Behaviour of Yellowlegs

Unusual feeding behaviour and habitat use by koaro

Large koaro (Galaxias brevipinnis) were observed drift-feeding in the water column and from the surface in a pool in Cave Brook, a tributary of Big River draining the Gouland Downs, Kahurangi National Park, an area free of introduced trout. This contrasts with the habitat commonly perceived as being koaro habitat which are cascades and fast, boulder riffles. It is suggested that sampling limita...

Feeding behaviour in rabbits

As a monogastric herbivore, the rabbit presents a unique feeding behaviour compared to other domestic animals, since he belongs to the Lagomorpha order (Leporidae family: rabbits and hares, Grassé and Dekeuser, 1955), and consequently possess a main specificity that is the caecotrophy. For recall (see details in chapter 1), the caecotrophy is a complete behaviour involving an excretion and an i...

Peptidergic mechanisms in feeding behaviour.

Hyperphagia was induced in mice by p.o. administration of different types of CNS depressant drugs, like chlordiazepoxide 25 mg/kg diazepam 2.5 mg/kg, cyproheptadine 2 mg/kg and phenobarbitone 25 mg/kg. Such hyperphagia was abolished by pretreatment with naloxone 0.1 mg/kg sc. Naloxone per se at this dose produced no significant effect on the food intake. This is suggestive of the role of peptid...

Animal Behaviour: Feeding the Superorganism

Insect societies are often described as superorganisms, and there are many functional parallels between organisms and superorganisms. Elegant work using ants shows that nutrient regulation, which occurs in many non-social animals, can also occur at the colony-level.
