Ethology of reef fishes especially regarding
UV vision
The zoology department has an active program in the behavior of
marine reef animals. We are best equipped and prepared for research
on reef fishes but will entertain proposals for work on other animal
groups. Research centers on the Coconut Island facility of the Hawai'i
Institute of Marine Biology. I favor research on ethological approaches
to social and symbiotic behavior of fishes. A strongly quantitative
and experimental approach is standard. My current interests are
in the behavioral control of sex change, analysis of social or symbiotic
communication, the functions of UV-sensitive vision in marine animals
and continuing interest in cleaning symbiosis. The laboratory is
unsurpassed in access to coral reef environments and is well equipped
with running seawater aquaria, video and computerized event recording
analysis of behavior. I do not encourage sociobiological approaches
and will not accept students working on marine mammals.
Current projects:
| - |
Mate choice
and sexual selection in gobiid fishes. |
| - |
Cleaning symbiosis
of green sea turtles by reef fishes. There are some interesting
questions as to why this apparently abundant food supply has
not been exploited by more fishes. |
| - |
The ethology
of sex change and sex determination in Dascyllus spp.
and detailed description of the behavioral changes that occur
during sex change in damselfishes. |
| - |
Study of the
UV visual world of shallow water reef organisms, UV vision and
UV coloration in reef fishes allowed by the development of a
unique underwater UV-sensitive video system. |
