Ramiro D. Crego is a post-doctoral researcher at the Smithsonian Conservation Biology Institute. Ramiro obtained his bachelor’s degree at the College of Natural Sciences and Museum Studies, National University of La Plata, Argentina, an M.S. at Southern Illinois University Carbondale, USA, and a Ph.D. at the University of North Texas. Ramiro’s research interests are in the field of ecology and conservation biology. Ramiro has been conducting studies focused on assessing methodological and theoretical approaches that can bridge the gap between ecological systems and human society. He is interested in the most fundamental state variables in ecology, distribution and abundance of species, and how these state variables respond to rapid global changes. These include, invasive species, climate change and different human activities, such as, livestock production. Ramiro’s work has had an emphasis on birds and mammals inhabiting semi-arid grasslands of Argentina and Kenya, and temperate forests in southern Chile. In his studies, Ramiro uses a combination of field data collection, remote sensing, and advance modeling techniques. Results from different studies have a focus on creating information that can help managers to make science-based decisions to protect the environment and the people that live and depend on it.
