Abstract. We used normalized size spectra analysis (originally developed in the study of pelagic communities) and a fish bioenergetics model to examine whether predation by fishes affects the size structure of macrobenthos. We conducted the study over five years in three north temperate lakes in which fish were experimentally manipulated while allowing for natural recruitment and m...

European Journal of Entomology ; Key words. Body size, constraint, diet composition, herbivory, insect, leaf toughness, Papua New Guinea, phenology, specificity, plant defence, young leaves Abstract. The hypothesis that small body size is correlated with preference for young leaves was tested in a community of leaf-chewing insect
Gender, body size and social relations in American high schools.
Social Forces ; Although some cultures assign prestige to large bodies, American culture has historically stigmatized obesity. This stigmatization is so powerful that it encompasses not just the clinically obese or overweight but also any above-average (and even average) body size (Allon 1981; Anderson et al.

Energetic constraints and the relationship between body size and home range area in mammals.
Ecology ; INTRODUCTION A recent review on the relationship between home range size and body size in mammals concluded that we presently know less about the scaling of home range area than about the dependence on size of almost any other ecological, anatomical or behavioral variable (Reiss 1988:86).

HISPANIC AND WHITE CHILDREN'S JUDGMENTS OF PERCEIVED AND IDEAL BODY SIZE IN SELF AND OTHERS.
The Psychological Record ; Male and female children, 189 in number, ages 7, 10 or 13 from white and Hispanic ethnic groups participated. Children selected their perceived and desired ideal body size, using figure line drawings of children of varying sizes. They made judgments for both same sex and opposite sex children. Boys
Temporary shift of body size in hooded crows Corvus corone cornix of NW Italy
Folia Zoologica ; Abstract. Unusual climatic events are known to influence micro-evolutionary changes in birds through selection and directional evolution of body size. In NW Italy a notable climatic episode occurred from 1984-85 to 1986-87 when the winters were unusually severe. In the periods 1986-88 and 1997-2000

MATERNAL PERCEPTION OF BODY SIZE AS A DETERMINANT OF INFANT ADIPOSITY IN AN AFRICAN-AMERICAN COMMUNITY
Journal of the National Medical Association ; For 10 weeks, a sample of 105 postpartum African-American clients of three inner-city clinics, were recruited for this nine-month prospective study. Data from 54 mother-infant dyads were used to explore the associations between maternal perceptions of infant body size and the development of
