In January the Winemiller Aquatic Ecology Lab welcomed two more visiting scientists from Brazil. Marcelo Andrade is a doctoral student from the Universidade Federal do Pará, Belém, Brazil, and Eduardo Cunha is a doctoral student from the Universidade Estadual de Maringá, Maringá, Brazil. Marcelo is researching the evolutionary ecology and diversity of fishes in the Amazon and major tributaries with emphasis on piranhas and their relatives (serrasalmid fishes). His major advisor at UFPA is Dr. Tommaso Giarrizzo. Eduardo is interested in theoretical ecology and is studying spatial complexity and food web ecology in the Upper Paraná River and its associated floodplains and reservoirs. His major advisor at UEM is Dr. Sidinei Thomaz. Both students will reside in College Station for one year.
