In Southern California, however, many areas have a mix of salt and fresh water\u2014such as estuaries, lagoons, and wetlands\u2014and very little is known about the type and distribution of toxin-producing algae in these areas. This uncertainty makes it difficult to understand or predict the algal threats posed to animal and human health in Southern California. University of Southern California (USC) Sea Grant funded a study to isolate, culture, and identify the toxin-producing algae in these fresh-salt ecosystems, providing a greater understanding of the presence of algae-produced toxins at \u2018hot spots\u2019 in the region.<\/span><\/p>\n\n\n\n<\/div>\n      \n      \n    <\/div>\n  \n  \n  \n\n  <\/div><\/div>\n\n\n\n\n  \n    \n\n\n\n\n\n\n<div\n  class=\"cc--component-container cc--rich-text \"\n\n  \n  \n  \n  \n  \n  \n  >\n  <div class=\"c--component c--rich-text\"\n    \n      >\n\n    \n      \n<div class=\"f--field f--wysiwyg\">\n\n    \n  <h3><b>Key Results<\/b><span style=\"font-weight: 400;\">:<\/span><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Surprisingly, Cyanobacteria\u2014a primitive life form that can also photosynthesize\u2014 not algae, make up a large number of potentially toxic species from over 50 locations along the Southern California coast\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">This is the first study ever to document the simultaneous presence of multiple algal &amp; cyanobacterial toxin contamination in estuarine ecosystems on the West Coast<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3><b>Project Impacts &amp; Application:<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The team established a culture collection of cyanobacterial species, providing a long-lasting community resource for further research<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Created publicly accessible maps on the presence of cyanobacteria and cyanotoxins in a variety of water bodies in Southern California<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Results were presented to the California State Water Control Board<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Dr. Caron participated in an expert workgroup to develop a Framework for Monitoring and Assessment of California Freshwater Harmful Algal Blooms<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3><b>Principal Investigators<\/b><span style=\"font-weight: 400;\">:<\/span><\/h3>\n<ul>\n<li><span style=\"font-weight: 400;\">David A.
