In an attempt to establish a relationship between food intake and fear/anxiety-related behaviours, the goal of this study was to investigate the effect of bilateral injections of GABAA (Muscimol, MUS, doses 25 and 50ng/side) and GABAB (Baclofen, BAC, doses 32 and 64ng/side) receptor agonists in the nucleus accumbens shell (AcbSh) on the level of fear/anxiety-like and feeding behaviours in 24h f...

Fast-start performance of northern pike Esox lucius (mean length, 0.38m) during prey capture was measured with subcutaneously implanted accelerometers. Acceleration-time plots and simultaneous high-speed cine films reveal four behaviours with characteristic kinematics and mechanics. The fast-start types are identified by the number of large peaks that appear in the acceleration-time and velocit...

The copepod Acartia tonsa exhibits 2 different feeding modes: when feeding on small phytoplankton cells it sets up a feeding current and acts as a suspension feeder; when feeding on motile prey it acts as an ambush feeder. We examined experimentally the effects of small-scale turbulence on feeding rates in these 2 modes. The different feeding behaviours were triggered by offering the copepods d...

OBJECTIVE To examine differences in feeding among children with cerebral palsy (CP) who varied in the severity of their oral motor involvement; to examine longitudinal change in feeding behaviours for different severity groups. METHOD Twenty-three children with CP participated (mean age = 4.53 years at the first time point). Feeding data were collected from parent questionnaires at 6 month in...

Contrary to a commonly held belief that broiler chickens need more space, there is increasing evidence that these birds are attracted to other birds. Indeed, commercially farmed birds exhibit a range of socially facilitated behaviours, such as increased feeding and preening in response to the presence of other birds. Social facilitation can generate feedback loops, whereby the adoption of a par...

Most New World leaf-nosed bats (Phyllostomidae) are frugivores. Many of these species are sympatric and mechanisms of resource partitioning including vertical strati®cation and divergent foraging strategies have been described. This study investigates a previously unexplored but potentially signi®cant factor in resource partitioning: the relationship between feeding behaviour and fruit hardness...

For small, arboreal marmoset monkeys, antipredator vigilance is essential to ensure survival. However, since incompatible with some other behaviours, such as feeding in a head-down position, it has be regulated efficiently within individuals and perhaps even at the group level. To investigate what drives individual differences behaviour common marmosets, Callithrix jacchus, whether they adjust ...

It was observed that when compared with indoor pigs, outdoor piglets spent significantly more time exploring and feeding and less time belly-nosing, showing oro-nasal or agonistic behaviour towards their pen mates. Belly-nosing and oro-nasal behaviours generally are considered aggressive rather than natural (Petersen, 1994). Höetzel et al. (2004) proposed that the decrease in unnatural behaviou...

Abstract Amphibians exhibit diverse parental care behaviours, which may be performed by the female, male or both parents. In Neotropical family Leptodactylidae, frogs in genus Leptodactylus different parenting behaviours. The repertoire of behaviours includes egg/nest attendance, nest chamber sealing, tadpole feeding with trophic eggs, and attendance associated complex such as pumping behaviour...
