Congresso Brasileiro Sobre Crustáceos (CBC)
The Crustacean Society (TCS) Summer Meeting


Tradition and Innovation:
Integrative Approaches to Crustacean Studies

Conference 1 - “Crabs of the world, the world of crabs”

Dr. Danièle Guinot
(Museum National d'Histoire Naturelle - France)

Crustacean Taxonomy. She has authored 207 publications, 5.608 citations and an h-index of 30.64. Researches mainly on Brachyura taxonomy Already described over 200 crustacean species and she was honored by several authors.

Our world is splendidly filled with an extraordinary diversity of crabs. Brachyuran crabs, the most evolved of all Crustaceans, number over 7,500 different species. They are animals that are sometimes loved, sometimes hated. They may seem familiar to some, but their fascinating world of amazing shapes, unexpected behaviours and wonderful adaptations never ceases to amaze us, to amaze me. A world yet to be discovered. What we call natural history is not a thing of the past, and only the knowledge of the crabs of the world, of the world of crabs can contribute to their protection and that of their natural habitats. I am going to make you love them by passing on you what I have learned about them from my researches since I started at the age of twenty and which has filled my life for more than 60 years. A whole life, and yet still so many questions…

Conference 2 - "Perspectives on crustacean osmoregulation: from systemic adjustment to fine-tuning molecular transport mechanisms"

Dr. John McNamara
(USP Ribeirão Preto, Brasil)

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.


Conference 3 - “Brachyuran Phylogeny: Achievements, Conflicts and Future Prospects”

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.


Conference 4 - “The Growth, Respiration and Reproduction of Crustaceans: a Synthesis through the Gill-Oxygen Limitation Theory (GOLT)”

Dr. Daniel Pauly
(University of British Columbia - Vancouver, Canadá)

Fisheries Biology. He has authored 415 publications, 25.914 citations and an h-index of 134. Researches on fisheries sustainability, applying concepts, methods and softwares which he has developed in partnership with several researchers and institutions all over the world.

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.
