1986. Biology Major. University of Murcia, Murcia, Spain
Born in Sevilla, Spain, I became interested in zoology (cool creatures!) early on in my childhood as I was moving to Madrid, Toledo, and Murcia. During my youth, largely in Murcia, I spent most of my weekends and summers hiking with the Boy Scouts of Spain and learning about nature. At this time, I also joined the environmentalist organization Asociacion de Naturalistas del Sureste and became involved in bird banding, amphibian surveys, and general conservation issues in Murcia and neighboring areas. While finishing college studies in Sevilla, I was interested in ornithology postgraduate studies on the ecology of wading birds in the Southwest of Spain. In 1988 however, I moved to the USA where I pursued my graduate degrees and developed my passion for amphibians and reptiles. I spent 12 years in Florida soaking Florida’s amazing biodiversity and, at the same time, saddened by its unbridled agricultural and especially urban growth. In 2002, I moved to Pennsylvania where I am happily teaching and doing research on species that I love, especially box turtles, and lately Pennsylvania snakes.
I am a vertebrate biologist, interested in ecology, behavior, morphology, and evolution. My research emphasis is population biology of amphibians and reptiles. With the use of comparative approaches, I examine morphological, ecological, and behavioral specializations that explain the current demographic status of species and communities. I am working on generating models that predict the fate of species under pressure from human disturbance.
I am establishing a long term and comparative study to address demographics and conservation of Pennsylvania's Herpetofauna. A major part of this study is being developed at Letterkenny Army Depot, Chambersburg, PA. I am interested on life history traits, behavioral characteristics, phenotypic plasticity, and their implications for the conservation of the species. In my research strategy, I combine traditional herpetological and field ecology techniques, as well as cutting edge remote sensing (GIS) and laboratory techniques such as genetics and molecular biology. I often cooperate with intramural and extramural colleagues interested in similar topics.
I am developing permanent lines of communication and interaction with research institutions in Florida (USA), Andalucia (Spain), and Murcia (Spain). I am committed to the early involvement of students in science through my teaching and my research projects, with the goal of developing their full understanding of the scientific methodology as well as the intricacies of the biological world
