Recent theoretical developments to explain the unimodal and asymmetric distribution of body sizes among species in higher taxa have yielded predictions for related demographic and life history traits. In particular, it has been predicted that there is an energetically optimal body size ([M.sup.*]) for terrestrial mammals at [approximately]100 g, and that the relationships of many biological characteristics will change slope or even sign at this point. We reanalyze a well-known data set on t...

	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.

	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
