The Aquatic Ecology at the University of Puerto Rico, Rio Piedras conducts research on the life history, ecology, evolution of freshwater organisms, and the limnology of stream ecosystems. We use a variety of approaches such as individual, population, community structure, toxicology, stable isotope analyses, field and laboratory experiments, GIS, and statistical techniques. Furthermore, we use habitat and shrimp, macro-invertebrates, and fish communities surveys and analysis tools to assess water quality and investigate anthropogenic perturbations' effects on freshwater communities and ecosystems. Topics of greatest interest are:

• life history strategies, environmental variation, and population dynamics

• food webs and trophic ecology

• species assemblage structure, environmental variation, and species functional traits

• species diversity, biogeography, and evolution

• effects of microplastics on the native and exotic organisms

• toxicology of pollutants on animal behavior.
