• Biogeochemical Pathways

    Research in the LM documents how long-term biogeochemical dynamics respond to pulse and press disturbances, the effects of  hurricane and the effects of more extreme wetting and drying events on forest biogeochemistry.

  • Ecosystem Services

    Land use changes will fragment adjacent terrestrial plant communities, reducing biophysical connectivity and biodiversity. We predict the development of “urban syndromes” in linked aquatic and terrestrial ecosystems along the flanks of the LM and a reduction in critical ecosystem services.

  • Canopy Trimming Experiment

    The Canopy Trimming Experiment (CTE) is a long-term experiment designed for two purposes: 1) to decouple the effect of canopy disturbance..., and 2) to increase the frequency of simulated hurricane effects above background levels to once every six to ten years.

  • Luquillo Forest Dynamics Plot

    The LFDP has a history of land use disturbance and also hurricane damage, disturbance types that interact and influence the community dynamics and species composition in the LFDP.

  • Multiple Dimensions of Biodiversity

    Functional biodiversity is more tightly linked to environmental characteristics and responds more strongly to both press and pulse disturbances than do taxonomic and phylogenetic biodiversity.

  • Urban-Rural Boundary

    Changing land use affect ecosystem services in northeast Puerto Rico.

  • New Pathways

    Research at Luquillo LTER led to the discovery of DNRA and Feammox, novel pathways for nitrogen loss from terrestrial ecosystems.

Mission statement: Explore spatio-temporal variation in ecosystem structure and function in dynamic tropical landscapes

The goal of the Luquillo Long-Term Ecological Research Program (LUQ) program is to determine how changing climate and disturbance regimes interact to drive ecological change in natural and human modified landscapes in tropical montane ecosystems. This enhanced mechanistic understanding will supply critical information to manage and conserve ecosystems of the Luquillo Experimental Forest as well as other montane forest ecosystems undergoing similar changes. Read More

Research Highlight

This video presents the importance of the conservation of freshwater ecosystems, specially tropical streams and rivers. Alan Covich presents a summary of the roles of the organisms that inhabit the freshwater streams of Puerto Rico and their importance in the ecosystem health and and services. Also gives recommendations for the conservation and preservation of this valuable resource for the next generations. (Produced by Freshwaters Illustrated with NSF support)
