Resumen de proyecto de investigación
Realizo investigación en ecología de comunidades con enfoque en interacciones entre especies. Me interesa entender por qué las interacciones entre especies cambian en el tiempo y en el espacio, cómo responden a disturbios antrópicos, y cómo dichos cambios en las interacciones afectan a las funciones ecosistémicas. También me interesa el uso de teoría de redes como herramienta para evaluar los cambios en los patrones de interacciones entre especies, así como para entender y predecir efectos directos e indirectos entre especies.
