معرفی
Alexander S Flecker is a Professor in the Department of Ecology and Evolutionary Biology at Cornell University's College of Arts and Sciences. His research spans tropical and temperate freshwater ecosystems with extensive fieldwork across South America, Mesoamerica, and the Caribbean. He serves in multiple graduate fields including Ecology and Evolutionary Biology, International Development, Natural Resources, and Conservation and Sustainable Development.
His educational background includes:
- Ph.D. in Zoology (Ecology and Evolution concentration), University of Maryland (1990)
- M.S. in Zoology, University of Maryland (1984)
- B.S. in Zoology, Oregon State University (1980)
Flecker's research focuses on the interface between community and ecosystem ecology, examining how biodiversity influences ecosystem functioning. His lab investigates stream ecosystems globally, with particular emphasis on Neotropical regions. Key research themes include: the role of animals as ecosystem engineers, migratory fish as nutrient vectors, eco-evolutionary interactions (particularly with Trinidadian guppies), trait-based vulnerability to climate change, and consequences of biodiversity loss from overharvest and invasions. His work integrates observational studies, experiments, and whole-ecosystem manipulations.
Analysis of his recent publications reveals strong interdisciplinary trends connecting computational sustainability with freshwater ecology. His work increasingly addresses Amazon hydropower planning tradeoffs, sustainable aquaculture development, and the nutritional dimensions of fisheries. The research spans from molecular-scale nutrient cycling to basin-scale ecosystem services, with growing emphasis on climate change impacts and socio-ecological solutions.
Flecker actively mentors graduate students and postdocs, with lab members pursuing diverse projects across the Americas. His teaching includes BioEE 1610 (Ecology and Environment), BioEE 4560/NTRES 4560 (Stream Ecology), and graduate seminars. He has received external funding supporting long-term research in tropical stream ecosystems and computational sustainability initiatives.
The Flecker Lab maintains active field sites across the Neotropics and collaborates with international institutions including the Organization for Tropical Studies and Brazilian research centers. Current projects focus on Amazonian aquaculture sustainability, freshwater soundscapes as biodiversity indicators, and computational approaches to hydropower planning that balance energy needs with ecosystem protection.
