Vera Maria Fonseca de Almeida e Val
type: Person
overview: Vera Val é pesquisadora do Instituto Nacional de Pesquisas da Amazônia (INPA-MCTIC) desde dezembro de 1981 e atua no Laboratório de Ecofisiologia e Evolução Molecular (LEEM-CBIO). Se formou em 1978 em Ciências Biológicas na UFSCar (São Carlos-SP) e realizou seu mestrado na mesma instituição (1979-1983), com adaptações de peixes a ambientes, no caso, a dissertação de mestrado comparou peixes vivendo em ambientes lênticos (lagos de hidroelétricas) com peixes vivendo em ambientes lóticos (rios e corredeiras). Se mudou pra Manaus em 1981 e iniciou seu doutorado em 1984 estudando metabolismo anaeróbico em peixes de locais hipóxicos por meio do efeito da temperatura sobre a enzima anaeróbica LDH, o qual finalizou e defendeu em 1986Ambos os estudos a levaram a entender que os peixes se adaptam aos seus ambientes e modulam suas proteínas para fazer isso. Realizou pós-doutorado na Universidade da Columbia Britânica (1990-1992) no Departamento de Zoologia, sob supervisão do Dr. Peter W. Hochachka estudando adaptações bioquímicas ao meio ambiente. Persistindo nesse objetivo, até hoje utiliza ferramentas modernas para entender como os peixes se adaptam às mudanças ambientais naturais e antrópicas. Se interessa pelo processo evolutivo que levou os peixes da Amazônia a fazer parte da mais rica biodiversidade de água doce do planeta. A dinâmica da bacia, suas flutuações ao longo de sua formação talvez tenham e continuem tendo papel fundamental nesse alto nível de especiação. Por isso, se uniu à equipe do PROJETO AMERICAS, pra entender se a captura de rios provocada por processos de erosão e igarapés abandonados provocam estruturação nas populações de peixes levando a um maior grau de especiação. Outra área de trabalho é o desenvolvimento de técnicas que evitem coleta de peixes para estudo de DNA como a técnica de DNA ambiental - eDNA (do inglês - environmental DNA). Muitos trabalhos têm mostrado que é possível estimar a ictiofauna de um local por essa técnica medindo apenas o DNA …

overview: Vera Val has been a senior researcher at the National Institute for Amazonian Research (INPA-MCTIC) since December 1981 and works at the Laboratory of Ecophysiology and Molecular Evolution (LEEM-CBIO). Graduated in 1978 in Biological Sciences at UFSCar (São Carlos-SP) and completed her master's degree at the same institution (1979-1983), with adaptations of fish to environments, in this case, the master's dissertation compared fish living in lentic environments (lakes of hydroelectric power plants) with fish living in lotic environments (rivers and rapids). She moved to Manaus in 1981 and started her doctorate in 1984 studying anaerobic metabolism in fish from hypoxic sites through the effect of temperature on the anaerobic enzyme LDH, which she finalised and defended in 1986. Both studies led her to understand that fish adapt to their environments and modulate their proteins to do so. She did her Postdoctorate at the University of British Columbia (1990-1992) in the Department of Zoology, under the supervision of Dr. Peter W. Hochachka studying biochemical adaptations to the environment. Pursuing this goal, it still uses modern tools to understand how fish adapt to natural and anthropogenic environmental changes. She is interested in the evolutionary process that led Amazonian fishes to be part of the richest freshwater biodiversity on the planet. The dynamics of the basin, its fluctuations throughout its formation, may and will play a key role in this high level of speciation. For this reason, she joined the AMERICAS PROJECT team to understand if the capture of rivers caused by erosion processes and abandoned streams causes structuring in fish populations leading to a higher degree of speciation. Another area of work is the development of techniques that avoid collecting fish for DNA study, such as the environmental DNA (eDNA) technique. Much work has shown that it is possible to estimate the ichthyofauna of a site by this technique by measuring only fish DNA from…
