Differences In The Diversity Of Frogspecies Between Sierra Lloronaand El Valle, Panama, Kei Okabe Thurber Dec 2014

Differences In The Diversity Of Frogspecies Between Sierra Lloronaand El Valle, Panama, Kei Okabe Thurber

Independent Study Project (ISP) Collection

Panama is home to the greatest diversity of species in all of Central America. It is home to 174 species of frogs, 35 of which are endemic to Panama. Frogs are a vital part of many ecosystems. They maintain insect populations and act as food sources for larger predators. Their job of maintaining insect populations is essential to curbing the spread of diseases. Additionally, scientists have found chemical compounds in the skin of frogs that can be used to treat pain and prevent infections. The main threat to the majority of frogs is the deadly fungus Batrachochytrium dendrobatidis (Bd), or ...


Comparing Disease Prevalence In Hard Corals At Four Different Reefs Near The Island Of Narganá In The Guna Yala Comarca Of Panamá, Connor Hinton Dec 2014

Comparing Disease Prevalence In Hard Corals At Four Different Reefs Near The Island Of Narganá In The Guna Yala Comarca Of Panamá, Connor Hinton

Coral reefs harbor much of the world’s known marine biodiversity. For a number of reasons, coral reefs are becoming increasingly threatened. Large portions of the world’s reefs have already been lost, and the number of degrading reefs is constantly on the rise. One cause for the destruction of coral reefs are coral diseases, ultimately causing coral mortality. With the death of corals, a key species is lost, endangering the entire reef ecosystem. Documenting the presence of such diseases could be useful in assessing current reef health and ameliorating the growing threat of coral diseases. In this project, 18 ...


Evaluating The Progress Of A Mangrove Reforestation Project On Isla Galeta, Colon, Abigail Hope Outterson Dec 2014

Evaluating The Progress Of A Mangrove Reforestation Project On Isla Galeta, Colon, Abigail Hope Outterson

Independent Study Project (ISP) Collection

Just off the Atlantic coast of Panama, a dynamic and self-renewing ecosystem takes advantage of the tropical climate and swampy conditions. Guarding Punta Galeta’s shores since before it was a U.S. navy base in the 1930’s, mangroves that have persisted here for centuries now draw scientists and tourists alike from all over the world to the Smithsonian Tropical Research Center. Once viewed as unproductive, distasteful environments, mangroves are increasingly recognized worldwide as critical habitat for endangered and commercially significant species, as well as for their ecological and aesthetic value. Uniquely adapted to survive in saline environments, mangroves ...


Oreaster Reticulatus: A Study Of 3 Aggregations In The Bocas Del Toro Archipelago, Rae Robinson Apr 2014

Oreaster Reticulatus: A Study Of 3 Aggregations In The Bocas Del Toro Archipelago, Rae Robinson

Independent Study Project (ISP) Collection

Las estrellas del mar son importantes para mantener un ecosistema estable y la cadena alimentaria de una sistema del mar. La especie de estrella del mar, Oreaster reticulatus, es un despredador de material particulada, algas, larvas pequeñas, y a veces tejido esponja. En el archipiélago de Bocas del Toro esta especie brillante es frecuente. Se ha sugerido que la competencia de alimentos entre individuos de las misma especie es un fenómeno que limitaría las recursos y por lo tanto las capacidades de crecimiento. Fue presumido que habría una relación inversa entre la densidad de población y tamaño de media de ...


A Case Study Of Rhincodon Typus Scarring In Ningaloo Reef: An Assessment Of The Current Scarring Classification System, Laura Korman Apr 2014

A Case Study Of Rhincodon Typus Scarring In Ningaloo Reef: An Assessment Of The Current Scarring Classification System, Laura Korman

Independent Study Project (ISP) Collection

Rhincodon typus are the largest fish in the sea, but little is understood about this elusive species. They are known to annually aggregate in Ningaloo Reef, Western Australia—the location of this study. In order to better understand this species, scarring was observed on a subset of the population that aggregates in Ningaloo Reef. In addition, the scarring classification system was examined to determine if it is the most effective classification system. R. typus were observed, and photographed from April 9th-April 25th, 2014. These photos were then used for identification and scarring classification purposes. The analysis of the scars on ...
