The research titled "Ecología funcional e impactos indirectos en 15 especies de tiburones presentes en la zona de Isla Fuerte en el Caribe Colombiano" investigates the role of functional diversity and indirect anthropogenic impacts on 15 shark species around Isla Fuerte in the Colombian Caribbean. Key aspects of the study include:<br>ObjectivesFunctional Diversity Analysis: Estimating functional diversity and redundancy among the shark assemblage to understand their roles within the ecosystem.Trophic Impacts: Evaluating indirect effects of fishing practices and their consequences on ecological balance and trophic cascades.Data Management: Developing plans for data sharing and further scientific publication.MethodologyStudy Area: Isla Fuerte's marine ecosystem, characterized by tropical dry forest climates and coral reef systems.Data Collection: Shark specimens were collected through artisanal fishing practices between 2004 and 2012, and stomach contents were analyzed to establish trophic levels.Traits Analysis: Functional traits such as body size, diet, activity period, swimming speed, and habitat position were examined.Indices Used: Metrics like Functional Richness (FRic), Functional Divergence (FDiv), Functional Evenness (FEve), and others were calculated using specialized R packages.Key FindingsFunctional Redundancy and Diversity: The shark assemblage had low functional richness but high functional divergence, indicating limited roles in the ecosystem but distinct ecological functions.Trophic Networks: Progressive declines in prey components (fish, crustaceans) due to overfishing could severely affect ecosystem stability.Vulnerability: The network's increasing vulnerability highlights the risks posed by anthropogenic pressures.ImplicationsThe study underscores the importance of integrating functional ecology into conservation strategies to maintain ecosystem stability. It highlights the need to address illegal and unsustainable fishing practices that threaten both shark populations and their critical roles as top predators. Further, it advocates for more detailed data collection and expanded research to strengthen these findings.This research provides a foundation for ongoing studies on the ecological significance of sharks and the cascading impacts of their decline due to human activities.
