Keltony Aquino is a researcher committed to preserving coastal ecosystems and passionate about marine biodiversity. His project expands knowledge about coastal ecosystems, including in this equation the role played by permanently dry areas and their terrestrial fauna. He graduated in biological sciences from the Federal University of Espírito Santo; his roots in the biology of decapod crustaceans opened the doors to a master’s degree in ecology and natural resources at the Universidade Estadual do Norte Fluminense Darcy Ribeiro. In this institution, he also completed his doctorate in the same area. His academic journey contributed to his in-depth knowledge of ecology and shaped him as an educator when Aquino was a scholarship holder in the Institutional Teaching Initiation Scholarship Program (PIBID). Later, the biologist also joined the team at the Natural History Museum of the South of the State of Espírito Santo. He is a postgraduate fellow at the Carlos Chagas Filho Research Support Foundation of the State of Rio de Janeiro. His project is essential to understanding coastal erosion and the factors that impact these delicate ecosystems and providing fundamental data for managing and conserving precious sandy beaches.
