Evolutive and Comparative Physiology. He has authored 122 publications, 2.214 citations and an h-index of 26. Researches on Physiological Ecology of Crustaceans in different habitats, proposing testable mechanisms and models for the transport of ions in the branchial epithelium and cells.
This presentation will review our knowledge of physiological and biochemical adjustments and the adaptations of crustaceans to their different biotopes and osmotic niches, focusing on the two main groups studied, the caridean shrimps and the brachyuran crabs. I will begin with the broad principles of hemolymph osmotic and ionic regulation, and examine the characteristics associated with different levels of structural organization: from wide-ranging systemic properties, through ion movements across epithelia dependent on transport by specialized cells, to the functional expression of genes and proteins that underlie ion regulatory ability. My aim is to bring together these different attributes of distinct structural levels in a coherent appraisal of how osmoregulatory physiology has developed over time, what are the current trends in ongoing research, and how we might best focus our attention on unresolved issues, such as hemolymph chloride regulation.
Dr. Marcos Tavares
(Museu de Zoologia USP, Brasil).
Invertebrate Zoology, with emphasis on crustaceans. He has authored 129 publications, 1.084 citations and an h-index of 15. His taxonomy research is based on the morphology of several groups of decapods, especially crabs, also contributing to the phylogeny of Brachyura. .
Major progress has been made towards consistent resolution for brachyuran crab phylogeny. Recent findings in the field are summarized. However, some major controversies (e.g., monophyly of Podotremata and Heterotremata, position of Cyclodorippoidea and Raninoidea) and poorly resolved deep nodes remain. Future directions are explored with particular emphasis to morphology.

Crustaceans breathe through gills which, given that they function as a (2-dimentional) surface, cannot keep up with the oxygen demand generated by the increasing weight of their (3-dimensional) bodies. This presentation will thus highlight the implication of the resulting ‘dimensional tension’ for the growth of crustaceans ranging in size from tiny copepods to large lobsters. Also, the reproduction of crustaceans will be shown to be a succession of events that do not shape their growth, but, which, on the contrary, are shaped by it. Finally, this presentation will show how the linkages implied by the GOLT between growth, respiration and reproduction explain multiple aspects of the life history of crustaceans. Also, the GOLT allows solid predictions of the likely effect of ocean and freshwater bodies’ warming on crustaceans.
