My laboratory is engaged in research on various topics in marine biology. Following are abstracts of four such projects:

1.Phylogeny of the octocorals (phylum Cnidaria), family Xeniidae: Application of molecular and morphology based approaches (jointly with Catherine S. McFadden, Harvey Mudd College, Clarmont, California; and Robert J. Toonen , University of Hawaii, Hawaii).

Octocorals are common throughout the Indo-Pacific coral reefs and play an important role in both the ecology and biodiversity of the ecosystem, yet they remain dramatically less studied in comparison to scleractinian corals. The project uses a multi-disciplinary approach to study the phylogeny of octocorals of the family Xeniidae, a highly abundant component of coral reef communities, particularly in the Red Sea . We consider the current genus-level taxonomy of Xeniidae as a phylogenetic hypothesis, and use molecular characters to determine whether or not morphologically-defined genera represent monophyletic groups. The objectives of the project are: (1) to provide identifications of Red Sea Xeniidae based on traditional morphological characters; (2) to produce an illustrated taxonomic key to the xeniids that can be used by both specialists and amateurs to identify species; (3) to construct a robust genus-level molecular phylogeny for the family as well as species-level phylogenies for the most diverse Red Sea genera; and (4) to test for congruence between morphologically-defined taxonomic groups and distinct clades supported by the molecular phylogeny.

2. Hydrodynamics of contact of larvae with substrate (jointly with Prof. G. Zilman, Faculty of Engineering, TAU)

Colonization of surfaces by larvae of marine organisms, including motile invertebrates, is a fundamental phenomenon of the marine environment with practical applications in engineering and biotechnology. Combating the biofouling of man-made underwater structures is a constant and prolonged scientific and engineering problem. Conversely, harvesting of attached colonies of marine organisms and increasing their yield is a relatively new problem relating to the production of chemical compounds that can be used as new effective drugs. We consider a larva as a hydrodynamic particle. In our project we include the self-propulsion of a larva in the analysis of its curvilinear motion, which is affected by the flow vorticity. To formulate the basic hypothesis of our study, we used the observations of Crisp (1955), who noted that larvae react to flow shear by using self-propulsion. We formulated the equations of motion of a self-propelled larva as for a rigid body with six degrees of freedom. We then calculated the hydrodynamic forces acting on the larva according to the existing theories of low and moderate Reynolds numbers. T he project experimental ly stud ied the motion of larvae in linear shear flow. The Couette flow apparatus, which has been built at TAU, is used to visualize the trajectories of larvae and to measure the probability of their contact with the walls of the tank and of a protruding cylinder.

3 . DynaLearn: Engaging and informative tools for imparting conceptual system knowledge (jointly with D. Meduisar, R. Nachmias, J. Ram and M. Leibe, School of Education and Dror Zurel, Department of Zoology, TAU and other EU consortium members)

Conceptual knowledge of a system’s behavior is crucial in order for society to understand and successfully interact with the environment. Acquiring this expertise is therefore a valuable aspect of science education. Despite this importance, there is an alarming decline in the number of students choosing science subjects. The DynaLearn project seeks to address this problem by integrating well-established, but currently independent technological developments, and utilizing the added value that emerges. Diagrammatic representations will be used for learners to articulate, analyze and communicate ideas, and thereby construct their conceptual knowledge. Ontology mapping will be used to find and match co-learners working on similar ideas to provide individualized and mutually beneficial learning opportunities, and virtual characters will be used to make the interaction engaging and motivating. The development of the workbench will be tuned to fit key topics from environmental science curricula, and evaluated and further improved in the context of existing curricula using case studies.

4 . The microbiology of an invasive marine oyster (Bivalavia) (jointly with Dr. U. Gophna, Department of Molecular Microbiology and Biotechnology, TAU)

Biological invasions in the marine environment represent a recognized worldwide threat to the integrity of native communities, economy and human health. Of the many factors that may promote or prevent a successful invasion, microbial pathogens and symbionts are attracting increased attention. The eastern Mediterranean Sea is susceptible to biological invasions, with the greatest influx of invaders resulted from the opening of the Suez Canal , which allowed the entry of Erythrean biota. The Indo-Pacific oyster Chama pacifica was first recorded from the Israeli Mediterranean coast of Israel in 1993. The microbiology of this species and its effect on the efficiency of the invasion and on the invaded ecosystem has not been explored. Bacteria are captured as food in marine bivalves, but may also accumulate in their digestive tract and gills. The project compares between the microbiology of the oyster populations in the Red Sea and the Mediterranean , aiming at understanding the processes that facilitated the invasion. For this purpose we use Automated Ribosomal Intergenic Spacer Analysis (ARISA), Length Heterogeneity PCR analysisr (LH) and 16s rRNA clone libraries methods, in an attempt to characterize possible symbiotic and parasitic bacteria. In addition, a comparison between the reproductive biology of oysters in the two ecosystems is carried out.
