      20. These results show beta diversity to be largely responsible for the
greater species richness of insects feeding on more widespread plants.
      21. From these results beta diversity was shown to be largely responsible
for the greater species richness of insects feeding on more widespread plants.
      22. Methane is generated from anaerobic decomposition in wetlands, and
increases in the area of permanently flooded rice cultivation are thought to ac-

able to presume to be high soon.
      24. Sientists consider the ecosystem to be the functional unit in ecology,
