Individuals of its own genus were the main food item of two species of tucunares (Cichla cf. ocellaris and Cichla monoculus) introduced into the Volta Grande Reservoir. The abundance of adult tucunares may cause intra-specific competition, possibly leading to the high cannibalism rates found.

A change in feeding behavior on the 15th and 16th day of the maternal cycle was observed in experimental bitches whose own litter was partly replaced, on the onset of the 15th day, by foster puppies 12-13 days younger. The number of feeding acts and the overall feeding time increased, as compared with the indices for 2 days preceding the exchange of puppies (the 13th and 14th day of the materna...

Seasonal fluctuations in food availability show a tight association with seasonal variations in body weight and food intake. Seasonal variations in food intake, energy storage, and expenditure appear to be a widespread phenomenon suggesting they may have evolved in anticipation for changing environmental demands. These cycles appear to be driven by changes in external daylength acting on neuroe...

OBJECTIVES The present study aimed to ascertain whether parental reports of their feeding practices are associated with independent observations of these behaviours, and whether the reliability of maternal report depends upon the child's weight. METHODS A total of 56 mothers and their children ate a lunch to satiety which was videotaped and coded for maternal use of control during feeding. Mo...

To understand how parents of adolescents attempt to regulate their children's eating behaviors, the prevalence of specific food-related parenting practices (restriction, pressure-to-eat) by sociodemographic characteristics (parent gender, race/ethnicity, education level, employment status, and household income) were examined within a population-based sample of parents (n=3709) of adolescents. L...
