  abstract: Small, motile invertebrates associated with coral reefs are
  abstract: an important component of the reef community. Previous
  abstract: studies of these organisms have largely neglected any
  abstract: questions involving those organisms epizoic on living coral
  abstract: surfaces. methodological limitations have probably been one
  abstract: of the reasons for this neglect. In this research, I
  abstract: developed and tested a method to study spatial patterns in
  abstract: small epizoites on relatively simple surfaces. I used this
  abstract: sampler to study epizoite spatial patterns on areas of
  abstract: Montastrea amularis colonies in various physical regimes. I
  abstract: did preliminary samples to estimate the variability that
  abstract: might be associated with subsequent tests. In the water
  abstract: column, as in terrestrial systems, light is a major physical
  abstract: influence on the spatial patterns of organisms. Epizoite
  abstract: spatial patterns were studied in relation to coral surface
  abstract: light regimes. Two common epizoic species, the
  abstract: siphonostomatoid copepod Asteropontius proximus and a
  abstract: halacarid mite with parasitic mouthparts, were distributed
  abstract: significantly toward the sun in the morning and evening. A
  abstract: variety of small harpacticoid species also showed this
  abstract: pattern, but no species occurred consistently enough for
  abstract: statistical analyses. In all the phototactic species, mid-
  abstract: day abundances on top of the corals were too low to confirm
  abstract: that organisms were tracking the sun across the coral
  abstract: surfaces-Dye streamlines were used to determine high- and
  abstract: low-flow surfaces on the sides of M. amularis colonies. I
  abstract: sampled epizoites in these high and low-flow zones on coral
  abstract: heads along a forereef transect. Both absolute abundances
  abstract: and relative abundances between types of organisms differed
  abstract: significantly between the high and low-flow surfaces of the
  abstract: corals. Copepod abundances were very low on high-flow days,
  abstract: but I detected a fairly strong trend of increasing
  abstract: abundances with depth. This study demonstrates that
  abstract: informative studies of epizoic organisms can be done on
  abstract: coral reefs if measures are taken to minimize experimental
  abstract: error. Overall, the results appear to fit a model of a
  abstract: community structured by a combination of behavioral
  abstract: interactions and physical extremes. Greater knowledge
  abstract: concerning these organisms may lead to a better
  abstract: understanding of factors influencing the health of reef
  abstract: corals. The ability to quantify and model the abundances of
  abstract: organisms on consistent substrates like some corals may
  abstract: eventually be applied to monitoring the health of coral reef
  abstract: systems.
