    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Zoology; Ecology; Butterflies; Reproduction; Life histories; Trade-offs; Resource use; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : The life-history of an organism can be studied and understood in terms of acquisition and expenditure of resources.

    Sammanfattning : Dominant explanations of segregation argue that patterns of spatial residential sorting are shaped by the aggregation of individual residential choices, guided by discrimination, differences in resources, and preference-based explanations of neighborhood ethnic composition. However, research on social networks indicates that social influence can serve as a driver of collective outcomes that result in social organization. LÄS MER
