The Periphyton Analysis Laboratory (PAL) is a recharge center operated by Evelyn Gaiser's algae laboratory at FIU. The PAL offers specialized analysis and identification of microalgae from a wide range of aquatic ecosystems, focusing on substratum-attached algae (periphyton) but supporting analyses of phytoplankton as well. Gaiser has 30 years of experience working with algae and is an accomplished diatom taxonomist. Her lab focuses on studies of algae as sentinels of environmental changes occurring at local and global scales. The PAL provides support for the quantification, identification and enumeration of algae from lakes, rivers and wetlands around the world, using contemporary nomenclature and methods.

Activities in the laboratory include:

  • Guidance of sampling and collections management protocols
  • Sampling and collecting algae
  • Assistance and training in algal identification for grants, contracts and workshops
  • Processing of algal samples to quantify abundance and composition
  • Interpretation of results
