Costa Rican Frogs: What a beauty!

Hello! My name is Wagner and I’m a Costa Rican researcher. I am particularly interested in animal behaviour studies, and for the last four years I have been developing and participating in bio-acoustical and conservation projects with Costa Rican herpetofauna. If you haven’t heard or read much about my country, then I`d just say that it can easily be considered a paradise for herpetologists.

One of my projects seeks to describe a paternal care behavior in a glass frog species (pictured), as well as to determine the implications of the male`s presence in the hatching rate of the embryos (I`ll tell you more about this project in further posts). Last year I was invited to participate on the tropical field course in Costa Rica with the University of Manchester. I worked with all the students, Andrew and the other professors, who always made me feel very welcome.

The incredible experience the field course provided has definitely enhanced my commitment towards studying amphibians and reptiles. During the course I conducted a brief three-day survey to determine if the presence of other anuran species affected the calling activity of the Red-eyed tree frog, Agalychnis callidryas (pictured). It also allowed me to analyse changes in the acoustic activity of the species regarding its temporal and spatial distribution.

Our shared goal of preserving healthy species` populations in Costa Rica requires efforts by all amphibian conservationists to increase our knowledge of species` natural history as well as to develop effective non-invasive conservation strategies. I believe that by conducting detailed research studies, more accurate decisions can be then be taken for the protection of different species and their ecosystems in Costa Rica. In the future I hope to share more with you on frogblog about my personal research projects and my experiences in the forests of the Costa Rican Atlantic slope.

  1. I can tell that personally I know Wagner and his research projects. His research, eventhough kind of new, a year a think, is valuable not only for science, but also for conservation because of his focus on behavior relate to reproductive aspects. For me Wagner´s passion for herpetology is one of the best example of the youth of Costa Rica that will drive conservation in the neotropics the next decades. Greatings Wagners!

    • Thank you Marcelo. I really appreciate what you wrote. After all, I am not the only one trying to protect our ecosystems. Each of us plays a very important role in the conservation of species.

      Best of the vibes for you and your projects!
