YOUNG, C.M.*; VASQUEZ, E.; SVANE, I.: Early Life-History Strategies of Sessile Invertebrates in Stratified Fjords and Coastal Lagoons The larvae of sessile marine animals are faced with the difficult challenge of selecting a habitat that will be appropriate for the entire adult life. Many processes occurring in the water column prior to settlement help determine […]

SPICER, J.I.: Development of cardiac function in crustaceans: patterns, processes and implications While our knowledge of cardiovascular function in adult crustaceans is reasonable, our understanding of how that function comes into being during ontogeny is still, quite literally, embryonic. In this presentation I will briefly outline the different patterns of the onset and development of […]

DONOGHUE, M.J.: The Integrative Nature of Historical Biogeography I will argue that historical biogeography has failed to live up to its potential because the objectives of the discipline have remained uncertain and because its methods have failed to properly integrate the variety of relevant inputs. Specifically, in the development of cladistic biogeography evidence on the […]

MCFALL-NGAI, M.J.; KIMBELL, J.R.: The Euprymna scolopes-Vibrio fischeri symbiosis: From genes to demes The monospecific light organ association between the Hawaiian sepiolid squid Euprymna scolopes and the marine luminous bacterium Vibrio fischeri has been used as a model for the study of the most common type of animal-bacterial interaction, i.e., the association of coevolved Gram-negative […]

HOSHI, M.; KOBAYASHI, K.; ARIOKA, S.; HASE, S.; MATSUMOTO, M.: Switch From Asexual To Sexual Reproduction Many metazoans convert the reproductive modes presumably depending upon the environmental circumstances and/or the phase of life cycle, but the mechanisms underlying the switching from the asexual to the sexual reproduction, and vice versa, remain unknown in metazoans. We […]

KIRK, David L.: Seeking the Ultimate and Proximate Causes of Volvox Multicellularity Volvox and its relatives provide an exceptional model for integrative studies of the evolution of an important developmental novelty. The volvocine algae are green flagellates that range in complexity from unicellular Chlamydomonas through several colonial genera with a single cell type, to Volvox […]

MOUNOLOU, J.C.: Integrative approach of the science and the management of genetic resources. The overall goal of genetic resources management is to provide our generation and future ones with the biological material they need for actual and possible uses. This management implies a thorough identification of genetic diversity and of its expressions in diversified ecosystems, […]

GHIRADELLA, Helen; The University at Albany: The mystery of firefly flash control Over decades of study, researchers have worked out the basic anatomy, biochemistry, and neuropharmacology of lanterns of those fireflies that can flash, turning the lantern sharply on and off. However, the actual mechanism by which this turning on and off is controlled remains […]

HANSON, Frank E.; Unvi. Md. Baltimore County: Synchronous Flashing by Asian Fireflies: Mechanisms Unmasked Fireflies in many parts of the world exhibit communal flashing with various degrees of synchrony. Those in S.E. Asia are particularly spectacular with nearly perfect synchrony and continuous displays that last for hours. For some spp., the machinery responsible for getting […]

COPELAND, J.; MOISEFF, A.; Georgia Southern University; University of Connecticut: Synchronic flashing in a North American firefly Synchronic fireflies produce flashes with remarkable temporal precision. This phenomenon was first studied in Southeast Asian fireflies by Buck, Buck, Case, and Hanson. Recently, we described synchronic behavior in the North American firefly Photuris frontalis. Ph. frontalis is […]
