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.
HERBIVORE ABUNDANCE AND GRAZING INTENSITY ON A CARIBBEAN CORAL REEF
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.
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.
Flash signal evolution, mate choice, and predation in fireflies.
This review provides new insight into how firefly flash signals have been shaped by the dual evolutionary processes of sexual selection (mate choice) and natural selection (predation), and proposes several exciting directions for future research.
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.
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.
An integrative view of sexual selection in Tribolium flour beetles
This review takes an integrative approach to sexual selection in Tribolium flour beetles (Coleoptera: Tenebrionidae), a particularly well‐studied and economically important model organism.
