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


Tradição e Inovação:
Abordagens Integrativas ao estudo de Crustáceos

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

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

Taxonomia de Crustáceos. É autora de 207 publicações, 5.608 citações e um índice h de 30,64. Pesquisa principalmente na taxonomia da Brachyura Já descreveu mais de 200 espécies de crustáceos e foi homenageada por diversos autores.

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)

Fisiologia Comparada e Evolutiva. Autor de 122 publicações, 2.214 citações e h-index 26. Realiza pesquisas sobre Ecologia Fisiológica de Crustáceos em diferentes habitats, propondo mecanismos e modelos testáveis para o transporte de íons no epitélio branquial e nas células.

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).

Zoologia dos Invertebrados, com ênfase nos crustáceos. Autor de 129 publicações, 1.084 citações, h-index 15. Pesquisas sobre taxonomia com base na morfologia de vários grupos de decápodos, em especial dos caranguejos, também contribuindo em estudos sobre a filogenia de braquiúro.

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)

Biologia Pesqueira. Autor de 415 publicações, 25.914 citações e h-index 134. Realiza pesquisas sobre a sustentabilidade pesqueira, com conceitos, métodos e softwares que desenvolveu em parcerias com vários pesquisadores e instituições por todo o mundo.

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.
