Download or read book Rare Coastal Dune Lakes written by Ginger Jackson Sinton. This book was released on 2013-05-10. Available in PDF, EPUB and Kindle. Book excerpt: Northwest Florida is home to fifteen rare coastal dune lakes that share an intermittent connection with the Gulf of Mexico. This full-color, 112-page photo book reveals the beauty and rarity of the lakes and the surrounding emerald coast communities along the Scenic Highway 30A area. The dune lakes are mostly freshwater lakes with occasional saltwater exchange from the gulf, creating biologically diverse ecosystems. Natural habitats for a huge variety of flora and fauna, coastal dune lakes are brackish, dynamic, geological treasures in South Walton County, Florida. Author/photographer Ginger Jackson Sinton explores the beauty of the lakes and the diversity of the ecosystems surrounding them. With an eye for nature and the environment, she weaves personal anecdotes through the photo guidebook. The ?Sense of Home? in the subtitle is twofold: the dune lakes habitats of native plants and animals and her own fondness for the colorful locale along the gulf coast.

Book excerpt: ABSTRACT: The coastal dune lakes of northwest Florida are globally rare ecosystems with intermittent connections to the Gulf of Mexico that result in mix of freshwater and estuarine characteristics. They are managed as freshwater lakes, but most lakes are not protected by numeric nutrient criteria. This study examined 13 coastal dune lakes in Walton County, Florida, through multivariate analyses of water quality data using principal component analysis, cluster analysis, and hypothesis testing with a similarity profile. A classification analysis revealed three lake classes: fresh, mixed, and estuarine. A temporal analysis revealed that the lakes did not change class over ten years, with the two exceptions likely the result of physical changes to the Gulf outlets of those lakes. Climatic variation was evident in all lakes, which affected outlet connection type and frequency, and suggested that phytoplankton biomass accumulation was limited by water residence time. Lake morphology, geographic orientation, and density stratification appeared to cause frequent bottom hypoxia in two of the lakes. A comparative analysis showed that the coastal dune lakes are more similar to the regional estuary, Choctawhatchee Bay, than to a regional freshwater lake. Existing water quality data were used to develop proposed numeric nutrient criteria.

Download or read book Characterization of Fish Communities in the Northwest Florida Coastal Dune Lakes Using Environmental Dna Metabarcoding written by Nichelle Marie VanTassel. This book was released on 2018. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Coastal Dune Lakes (CDL) are rare aquatic habitats worldwide. Northwest Florida Coastal Dune Lakes (NWFLCDL) are even more rare and unique habitats due to their characteristic intermittent connection to the Gulf of Mexico. These intermittent connections can cause temporary estuarine environments. While there are policies in place to help protect and preserve the lakes and their surrounding area, little is known about the fish communities of NWFCDL. As traditional sampling to monitor fish communities can be costly and timeintensive, this project aimed to characterize and monitor the fish communities of the NWFLCDL using environmental DNA from water samples and metabarcoding. Metabarcoding involves using generalist molecular markers to describe diversity within a specific taxonomic group. Seventy-two samples across 19 lakes were sequenced using Illumina HiSeq. Bar charts were used to display composition of operational taxonomic units (OTUs) spatially and temporally. Nutrient (phosphorus, nitrogen, chlorophyll concentration) and water quality data (specific conductance, temperature, dissolved oxygen, pH, turbidity, salinity) from previous studies and measurements taken in the field were used to describe how abiotic factors relate to the fish communities in the NWFLCDL. This project provides a baseline of information necessary to stress the importance of preserving unique habitats.
