Ecological data


  • As part of specific ecological studies, we had been collecting data on a variety of ecosystem processes, such as leaf litter decomposition, microbial respiration, and invertebrate and fish diversity.

Long-term data repository


  • All data is ultimately deposited in the databases of the Luquillo LTER program in Puerto Rico for long-term storage and access.    
  • Recent data and data that are in the process of publication might not be available at the LTER site.  Please contact us for further information (alonso.ramirez at ncsu.edu).
