Dr. Lesley de Souza

Postdoctoral Research Associate

Dr. Lesley de Souza holds a two-year postdoctoral research position that continues Shedd’s research in Guyana’s North Rupununi region, where intensive fieldwork is needed to assess and protect the area’s rich aquatic biodiversity. Dr. de Souza’s work will help conservation managers understand the role that Rupununi wetlands play in supporting fish diversity, which in turn will help establish scientifically sound fishing regulations. She also plans to identify and monitor the migratory routes and nesting sites of arapaima, one of the largest freshwater fishes in the world. Additionally, Dr. de Souza will study the physiological impacts on arapaima that are captured by sport fishermen. Before joining Shedd, Dr. de Souza spent nine years studying freshwater fishes in Guyana and other parts of Latin America. She also has extensive experience conducting reptile, amphibian, fish and invertebrate surveys in Alabama as a field assistant with multiple conservation agencies and research centers. She holds a Ph.D. in biology from Auburn University. 


Dr. Lesley de Souza, Research Associate
I am thrilled that my work directly impacts a species at risk as well as the indigenous communities in southern Guyana. And of course, the arapaima are my favorite animals at Shedd. I have the unique opportunity to see the species I am currently doing research on in our Amazon Rising exhibit.
