Three research collaborators are visiting the lab.  Two of these scholars are from El Colegio de La Frontera del Sur, San Cristobal de Las Casas, Chiapas, Mexico.  Dr. Rocio Rodiles and Dr. Miriam Soria Barreto are collaborating with Dr. Winemiller on fish community and food web ecology in the Rio Usumacinta Basin.  The Usumacinta is the largest river basin in Mesoamerica, and also supports the highest fish diversity.  Another member of the Usumacinta research team is Dr. Carmen Montaña of Sam Houston State University in Huntsville, Texas, and… Read More →

Caroline Arantes receives TCAFS Scholarship

AgriLife Logo

Caroline Arantes is interested in ecology and conservation of fishery resources in freshwater ecosystems, including fish population and community ecology, management approaches, and the effects of human drive-impacts. Caroline has worked extensively with local people, institutions and conservation organizations to implement community-based management systems for the arapaima, the Amazon’s most historically important and overfished species, and to develop research that seeks to understand a broad range of problems and research questions. Her researches has addressed fish biology, ecology, traditional knowledge, and resource governance and her studies have been published in eight peer-reviewed, international journals. She also published six book chapters, 30 abstracts in… Read More →

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… Read More →

Aquatic Ecology Lab Provides Training in Fisheries Methods to Cambodian Fisheries Students and Professionals

Dr. Winemiller and PhD students, Luke Bower and Dan Fitzgerald provided instruction in fisheries methods at the Cambodian Inland Fisheries Research and Development Institute (IFReDI) in Phnom Penh on February 1-2, 2016.  The workshop was attended by 25 individuals from IFReDI, the Royal University of Phnom Penh, and the Royal Agricultural University.  Students practiced laboratory methods for research on age and growth estimation using scales and otoliths, reproductive status based on examination of gonads/gametes, and dietary analysis based on analysis of gut contents.  Also provided was an overview… Read More →

During the Fall 2015 semester, the Winemiller Aquatic Ecology Lab has been hosting two visiting scientists from Brazil.  Rodrigo Ferreira Bastos is a doctoral student from the Pontifícia Universidade Católica do Rio Grande do Sul, Porto Alegre, Brazil, and Larissa Strictar Pereira is a doctoral student from the Universidade Estadual de Maringá, Maringá, Brazil.  Rodrigo is researching the trophic ecology of fishes and food webs in coastal ecosystems using stable isotope methods.  Larissa is investigating the implications of cannibalism for fish population and community ecology.  Both students will… Read More →

TWRI Mills Scholar Tony Rodger finds high flow events critical for lower Brazos fish

By Leslie Lee Tony Rodger, who graduated earlier this month with a master’s degree from the Department of Wildlife and Fisheries Sciences at Texas A&M University, studied minnow species in the lower Brazos River Basin to determine how environmental flows affected early life stage survival. His study concluded that high flow events help maintain the biodiversity of fish within the lower Brazos River. Rodger is a 2014–2015 Mills Scholarship recipient. These scholarships, funded by the W.G. Mills Scholarship Memorial Endowment and administered by the Texas Water Resources Institute, support… Read More →
