At some point in our lives we have asked questions regarding the environment, the animals that inhabit planet earth, and climatic conditions. How does an increase in temperature could affect some organisms? How do small changes in a specific environment can have a large-scale effect on our planet? How does human activity affect our bodies of water? These are some of the questions that Dr. Restrepo, an ecologist and professor in the Department of Biology at the University of Puerto Rico Río Piedras, is attempting to answer through her research projects.
Three out of seventeen species of coquí have undergone extinction due to temperature changes, loss of their habitat and the spreading of the Bd fungus. Climate change is threatening at least 11 more species which would have a devastating effect on the ecosystem.
