The Role of Herbivorous Fishes in the Organization of a Caribbean Reef Community
It is suggested that herbivorous fish grazing profoundly influences benthic species distributions and abundances within some tropical reef habitats and spatial variation in herbivory appears to be of fundamental importance in determining regional patterns of benthics community structure on tropical reefs.

Impact of coral predators on tropical reefs
The role of corallivores in reef trophodynamics is more complex than appreciated previously, and there is a growing body of evidence to support that even limited removal of tissue or skeletal structures has growth and/or fit- ness consequences for a scleractinian coral colony. Expand
The spatial distribution of herbivorous fishes across reef habitats does not appear to be simply explained by differences in reef topography, but may depend on complex interactions among proximity to nearby shelter, predator abundance, density of territorial competitors, and local availability of food resources.

Selective predation by parrotfishes on the reef coral Porites astreoides
Comparison of C:N ratios among possible dietary components suggests that macroborer consumption could potentially provide nutritional benefits to mainly herbivorous parrotfishes, and provides a novel explanation for selective coral predation by parrotFishes. Expand
Sources of Intraspecific Variation in Sperm Precedence in Red Flour Beetles
Results in T. castaneum and a reexamination of published studies reveal a high degree of intraspecific variation in sperm precedence, suggesting that mean values are insufficient to adequately characterize sperm-precedence patterns. Expand
Mechanisms of Sperm Transfer and Storage in the Red Flour Beetle (Coleoptera: Tenebrionidae)
Examination of mechanisms of sperm transfer during copulation in Tribolium castaneum (Herbst), red flour beetles, and describes the dynamics of sperm movement within the female reproductive tract finds that neither male body size nor copulation duration appear to influence the number of sperm transferred duringCopulation or thenumber of sperm stored within thefemale spermatheca.

This review takes an integrative approach to sexual selection in Tribolium flour beetles (Coleoptera: Tenebrionidae), a particularly well‐studied and economically important model organism. Expand
Sound production during feeding in Hippocampus seahorses (Syngnathidae)
Analysis of high-speed video and synchronous sound recordings of H. erectus indicate that the feeding click begins within 1-2 msec of the onset of the rapid feeding strike, which is not consistent with previous suggestions that sounds may be produced by cavitation due to rapid pressure changes within the buccal cavity during the feeding strike.

Parrotfish abundance and selective corallivory on a Belizean coral reef
It is found that members of the Montastraea annularis species complex, major builders of Caribbean reefs, were preferred targets of parrotfish grazing across all reef habitats, while M. franksi was consumed more at depth and a positive correlation between Sparisoma aurofrenatum abundance and M.franksi grazing incidence was found. Expand
Female role in sperm storage in the red flour beetle, Tribolium castaneum
Results suggest that female T. castaneum play an active role in moving sperm from the site of deposition into storage, with evidence that sperm motility is not affected by extreme hypoxia produced by anesthetization of the female with either carbon dioxide or nitrogen. Expand
