Frey and his colleagues made use of mathematical models to analyze the complex interplay
between ecological factors and population dynamics, and were able to demonstrate that populations can indeed respond in a coordinated fashion to chemical information even when the signal molecules are generated by only a subset of the cells.
I researched the interaction in various areas
between rabbits, arthropods, coyotes, plants, and weather information in order to determine how these
factors interact with one another to create a complete
ecological system.
According to this approach, understanding adolescent behavioral risk and protective
factors requires the consideration of
ecological effects, that is the social contexts in which the risk and protection occurs (Bronfenbrenner, 1977; Cicchetti & Lynch, 1993), as well as transactional effects, that is the reciprocal nature of the relationship
between adolescents» behavior and their social contexts (e.g., Cicchetti, Toth, & Maughan, 2000; Coatsworth et al., 2000; Sameroff, 1995).
