Aquatic Ecology Laboratory

College of Biological and Environmental Sciences
About us

Investigate and generate knowledge about the biology and ecology of freshwater ecosystems, with special emphasis on lotic ecosystems.

The Aquatic Ecology Laboratory's mission is to research and generate knowledge about the biology and ecology of freshwater ecosystems, with special emphasis on lotic ecosystems. We execute projects within various themes such as freshwater insect taxonomy, behavioral ecology, populations and aquatic communities, and we study the functioning and ecological processes in rivers and streams. We also carry out applied projects, related to bio-monitoring of freshwaters and the maintenance of ecological flows, to contribute to the conservation of rivers and the integrated management of water resources in Ecuador.

Community Outreach

Project “MINGA PARA MI RÍO

Logo

The Laboratory of Aquatic Ecology of USFQ (LEA-USFQ), with the support of the Water Protection Fund for Quito (FONAG) has created the voluntary and community program of river restoration and remediation called “MINGA PARA MI RIO." The word Minga is a Kichwa word that means "community work for the common good." This program aims to achieve local involvement to increase awareness of river problems and promote the incorporation of best environmental practices. In addition, it seeks to educate citizens, mainly children and young people, about the importance of these ecosystems and teach them through volunteer work, easy actions, and practices, how ordinary citizens can contribute to the management, improvement, and restoration of these unique and essential ecosystems, which these rivers are. The “MINGA PARA MI RÍO” project seeks not only to provide information to the community about aquatic ecosystems, their importance, functioning and threats but also to attract citizens in such a way that they are actively involved and can have an experience in the field in the which can know the ecosystem, understand its operation and work to remedy it.
