My research focuses on understanding the impacts of climate change on plant-microbe interactions, particularly in the context of wild tropical forests and agricultural systems. As climate change disrupts ecosystems, my work aims to shed light on the role of plant-fungal symbioses in maintaining ecosystem health, agricultural productivity, and resilience. This research is vital for ensuring sustainable food systems, biodiversity conservation, and ecosystem service provision in the face of environmental challenges.

Key Areas of Study:

 

Hurricane Disturbance and Fungal Symbionts in Tropical Forests:
Tropical forests are essential biodiversity hotspots, but climate change-induced disturbances, such as hurricanes, pose significant threats to these ecosystems. My research in Puerto Rico has focused on how hurricane damage impacts the diversity and composition of fungal symbionts associated with the roots and leaves of tropical forest trees. Using fieldwork, next-generation sequencing, and statistical analysis, I found that severe damage to forests leads to a decrease in symbiont biodiversity, suggesting that such disruptions could affect forest resilience and health.

Fungal Symbionts and Agricultural Systems:
Agricultural systems are directly impacted by climate change, and pathogen pressures threatening crop production. In collaboration with researchers in Arizona, I explored how fungal symbionts could protect cultivated plants, specifically lettuce (Lactuca sativa), from heat stress and disease caused by the pathogen Fusarium oxysporum f. sp. lactucae (FOL). Through a series of greenhouse and in vitro experiments, I identified fungal endophytes that not only inhibited FOL but also enhanced heat tolerance in lettuce. One particular endophyte showed promising results for future crop improvement, making it a focus for further research in enhancing crop resilience.

 

 

 

Agricultural Extension and Pest Management in Puerto Rico:
As Puerto Rico faces increased vulnerability to climate change, including more frequent hurricanes and rising pest pressures, it is essential to strengthen the adaptive capacity of local farmers. I conducted a survey to assess the needs and knowledge of Puerto Rican farmers regarding pest and pathogen management. Using this data, I developed educational resources, including a plant pathology lesson plan, to help farmers better manage crop health and improve resilience to climate change. This initiative aims to empower farmers, increase educational accessibility, and enhance the capacity of agricultural extension programs in Puerto Rico.

Research Significance:
My research contributes to understanding how climate change affects both wild ecosystems and agricultural systems, focusing on the critical role of plant-microbe interactions. By exploring how disturbances like hurricanes impact microbial communities, identifying beneficial symbiotic fungi for crops, and providing farmers with valuable educational tools, my work aims to foster adaptive strategies for both ecosystem conservation and sustainable agriculture.
