This study was therefore conducted to ascertain (i) the level of similarity between the periphyton diatom communities from karstic wetland sites in Belize, Mexico, Jamaica and comparable sites within the FCE, (ii) the relationship between periphyton biomass, TP levels and diatom community composition at these sites, and (iii) the feasibility of employing diatoms as indicators of water quality at these sites, using models relating diatom community composition to water quality from comparable sites within the FCE. Multiple wetland sites in Jamaica, the Yucatan region of Mexico and parts of Belize were visited between 2006 and 2008, during wet and dry seasons. At each site physico-chemical data were collected along with periphyton samples. The periphyton samples were processed in accordance with standard methods to obtain biomass, organic content and TP measures, and to identify and enumerate diatom and soft algae species. Various aspects of the diatom communities were then compared to previously compiled data on diatom communities from various parts of the FCE. SIMI analysis was used to determine the level of similarity between the systems and Non-Metric Multidimensional Scaling was used to identify relationships between diatom communities and water quality. Dataset Purpose This study was conducted and the data compiled to ascertain (i) the level of similarity between the periphyton diatom communities from karstic wetland sites in Belize, Mexico, Jamaica and comparable sites within the FCE, (ii) the relationship between periphyton biomass, TP levels and diatom community composition at these sites, and (iii) the feasibility of employing diatoms as indicators of water quality at these sites, using models relating diatom community composition to water quality from comparable sites within the FCE. Geographic Coverage Study Extent Description This study was conducted within multiple calcareous, shallow, short-hydroperiod, Eleocharis-dominated wetlands displaying similar characteristics in three countries. The areas visited included the New River Lagoon in Lamanai Outpost, Indian Church, Belize, the Slip River, Black River Morass, St. Elizabeth, Jamaica and the Sian Ka'an national Park, Quintana Roo, Mexico. Each wetland area was visited on two occasions intended to represent wet and dry seasons. The Mexico sites were visited in December 2006 ( which is typically a dry period but experienced high rainfall during 2006 and so served as a wet season sampling session) and March 2008 (which is typically a wet period but experienced low rainfall during 2008 and so served as a dry season sampling session). The Belize sites were visited in May 2007 (which served as a dry season sampling session and November 2007 (which served as a wet season sampling session). The Jamaica sites were visited in December 2007 (which served as a dry season sampling session) and March 2008 (which served as a wet season sampling session).

Description Eleocharis wetland areas were located within the region of interest and before sampling was conducted, water chemistry measurements, including pH, conductivity, salinity and temperature, were taken. At each Eleocharis wetland site, seven 1m2 areas were sampled using 1m2 throw traps. At each plot, a photograph was taken to record the surface view of the quadrat and the cover of periphyton on dominant substrates estimated. Periphyton was then cleared from plot, placed onto a seine net and sorted to remove animals, plants and marl. Periphyton only samples were then measured using perforated 2000 ml graduated cylinder which excluded water, and the periphyton biovolume was recorded. Submersed plants were then measured in the graduated cylinder to produce a total biovolume (Periphyton plus submersed plant) biovolume. A subsample of 120 ml (volume of urine cup) of periphyton only material was removed and placed in a sterile sample bag and placed in a cooler with ice for transport to the lab. When no observable periphyton mat was present, flocculent detritus was sampled non-quantitatively from the benthos and/or epiphytic fils were scraped from any macrophytes present. In the laboratory, each periphyton sample (in its sample bag) was weighed and a wet weight plus bag value recorded. The sample was then transferred to clean beaker, homogenized in a few ml distilled water (enough to fully moisten). The total volume of the homogenized sample was then measured in a graduated cylinder and this volume recorded as the Total Volume. The dried sample bag was then weighed and a bag weight recorded. From the homogenized Total volume, a 50 ml subsample was poured into a pre-weighed aluminum pan, dried in an oven for 24 hours and later removed and weighed to produce a Periphyton dry mass (DW). This sample was then placed in a muffle furnace for 3 hours and again weighed to produce an ash weight (AW). A 50 ml subsample was removed, placed in a labeled 120 ml cup and placed in an oven until dry. The dried contents were then ground and analyzed for nutrients (total phosphorus, total nitrogen, total carbon). A 1 ml subsample was removed and placed in a microvial for soft algae analysis. A 10 ml subsample was removed, put in vial and frozen until oxidized and analyzed for diatom analysis. A 1 ml subsample was removed and filtered through a GFF filter which was then analyzed for chlorophyll a.
