RESUMEN
Environmental problems have contributed to numerous collapses of civilizations in the past. Now, for the first time, a global collapse appears likely. Overpopulation, overconsumption by the rich and poor choices of technologies are major drivers; dramatic cultural change provides the main hope of averting calamity.

RESUMEN
Chaetodontids and acanthurids showed behavior that suggested the existence of dominance systems. There was no sign that the poster colors of chaetodontids serve as territorial signals, and there were interspecific differences in their responses to the mirror. Aggressive butterfly fishes usually butted with the spines of the forward part of the dorsal fin; surgeonfishes used their scalpels in attacks against their images.
