Lirey Ramirez M. Sc.

My research is mainly focus in plant community ecology in tropical alpine environments particularly in vegetation structure in treeline ecotone and paramo ecosystem, positive and negative plant-plant interactions and ecophysiology responses of plant species to abiotic stress and biotic interactions.

My dissertation is focused on seedling dynamics in alpine and tropical treeline ecotones, including establishment patterns, microhabitat preferences, and physiological responses to abiotic stress.
