BIOEXPO at UPRB
Our students presented two studies: one related to the presence of microplastics in the convict cichlid Amatitlania nigrofasciata, and a second study where students analyzed the fish community in the Guaynabo River.

Research Symposium at UPR-RUM 2024
Our students presented two interesting researchs: one related with the suitability of basaltic substrate for the sea urchin Echinometra lucunter, while another project focused on a demographic competition analysis of two species of freshwater snails.
Freshwater fish community in an anthropogenic gradient
In this project, an ecological study at the community level is conducted on two rivers in the southwest area of Puerto Rico, using data collected by NEON. Temporal and spatial changes in fish communities are analyzed under different environmental conditions.
Sea urchin: Artificial vs Natural Habitat
In this project, students analyzes the morphometry and demographic aspects of two populations of the Red Sea urchin Echinometra lucunter. One of these populations is in its natural habitat of limestone rocks, while the other is in an artificial environment created by humans, consisting of basaltic rocks.
Competition between two freshwater gastropods
In this experimental study, the abundance and dimensions of two introduced freshwater snails (Planobella duryi and Physella acuta) in rivers of Puerto Rico is investigated. The abundance and size structure of each species were analyzed separately, along with the competitive effect between them over a period of 10 wee
Diet analysis of the freshwater african catfish
In 2019, the exotic freshwater fish Clarias gariepinus was reported for the first time in Puerto Rico. Our current objective is to study its diet preferences, aiming to comprehend the potential impact of this species on our native freshwater ecosystems.
