Opposite relationships between invasibility and native species richness at patch versus landscape scales
Article Abstract:
The observed switch at different scales from a positive to a negative relationship between Rhamnus cathartica cover and native richness supported the hypothesized scale dependence of the relations. The results suggest that landscape patterns of invasion may be best understood in light of the combination of many factors including native diversity, native cover, and propagule pressure.

Population and community variability in randomly fluctuating environments
Article Abstract:
Population and community stability under constant and fluctuating temperatures in simple planktonic assemblages of differing algal richness are examined. Results from an experimental model system demonstrate a stabilizing effect of environmental fluctuations at the community level.
