The commonly observed high diversity of trees in tropical rain forests and corals on tropical reefs is a nonequilibrium state which, if not disturbed further, will progress toward a low-diversity equilibrium community. This may not happen if gradual changes in climate favor different species. If equilibrium is reached, a lesser degree of diversity may be(More)
By means of controlled experimental manipulation of populations in a natural field situation, I was able to demonstrate the mechanism of operation of interspecific competition between two species of barnacles , as well as the influence of predation on the intensity of this competition.

nfectious diseases have recently caused substantial community and ecosystem-wide impacts in marine communities. A long-spined sea urchin disease virtually eradicated urchins from the Caribbean and facilitated a coral to algal shift on many reefs (Hughes et al. 1994). Coral diseases , such as white band (Figure 1), white plague, white pox, and aspergillosis(More)
Olive fruit flies [Bactrocera oleae (Gmelin)] occur at densities in California that can result in intraspecific larval competition within infested fruit. Larval B. oleae densities tracked in the field at six location were found to be highly variable and related to the proportion of fruit infested and adult densities. Egg and larval distribution within the(More)
HYPOTHESIS To qualitatively assess the different acoustic signatures of an otologic drill burr-bone interface during temporal bone dissection on full thickness calvarial and thin tegmen bone. BACKGROUND An appreciable change in the sound generated by drilling occurs with progressive thinning of the bone during temporal bone dissection. To date,(More)
