Research on their natural history and ecology was published in three scientific journals.

After eight decades without scientific publications on their natural history and limited studies on their ecology, researchers confirmed the presence of 49 species belonging to the order Odonata in Puerto Rico.

They also found that the canalization of rivers and streams can affect the abundance of these organisms in urban habitats, and identified that three Caribbean endemic species are abundant in two streams of El Yunque National Forest.

It is envisioned as a safe alternative for researching the ecology and biology of these amphibians.

While studying a fungus that is rapaciously threatening amphibian populations around the world, Puerto Rican scientist Janelle A. Peña found a technique for direct developmental frog tagging in juvenile stages, which presents less risk to the organisms, is an economical option for researchers, and proved to be efficient with individuals up to 10 millimeters in diameter.

Researchers at the University of Puerto Rico (UPR) studied mummified fecal remains (coprolites) of two extinct pre-Columbian cultures that inhabited the island and, when compared with samples from native communities that still exist and urban communities in other parts of the world, found that the diversity of microscopic fungi (mycobiome) in the intestines of the first settlers was lower than in the current ones.

Although it has been scientifically recognized that the Puerto Rican bee is highly valued for its docility and resistance to diseases and pests that attack this species in other countries, Puerto Rico has not developed a beekeeping market that could not only contribute economically to the government, but also help in the pollination process in local and international agricultural sectors.
