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.

Book Synopsis Marine Metagenomics by : Takashi Gojobori

Download or read book Marine Metagenomics written by Takashi Gojobori. This book was released on 2019-07-24. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the state-of-art marine metagenome research and explains the method of marine metagenomic analysis in an easy-to-understand manner. Changes in the marine environment due to global warming and pollution have become a major global problem. Maintaining a healthy marine ecosystem requires advanced environmental monitoring and assessment systems. As such, the book presents a novel metagenomic monitoring method, which has been developed for comprehensive analyses of the DNA of microorganisms living in seawater to further our understanding of the dynamics of the marine environment. The book can be used as a primer for new researchers and as a manual on experimental methods.

Available in PDF, EPUB and Kindle. Book excerpt: Coastal and estuarine environments at the interface of terrestrial and marine areas are among the most productive in the world. However, since the beginning of the industrial era, these ecosystems have been subjected to strong anthropogenic pressures intensified from the second half of the 20th century, when there was a marked acceleration in the warming (climate change) of the continents, particularly at high latitudes. Coastal ecosystems are highly vulnerable to alteration of their physical, chemical and biological characteristics (marine intrusion, acidification of marine environments, changes in ecosystems, evolution and artificialization of the coastline, etc.).In contact with heavily populated areas, these environments are often the receptacle of a lot of chemical and biological pollution sources that significantly diminish their resilience. In this context of accelerated evolution and degradation of these areas important for food security of many populations around the world, it is necessary to better identify the factors of pressure and understand, at different scales of observation, their effects and impacts on the biodiversity and on the socio-eco-systems, in order to determine the degree of vulnerability of these coastal ecosystems and the risks they face. A transdisciplinary and integrated approach is required to prevent risks. Within this framework, operational coastal oceanography occupies an important place but also the implementation of a true socio-eco-system approach in order to set up an environmentally friendly development.

Book Synopsis Biological Invasions in Marine Ecosystems by : Gil Rilov

Download or read book Biological Invasions in Marine Ecosystems written by Gil Rilov. This book was released on 2008-11-12. Available in PDF, EPUB and Kindle. Book excerpt: Biological invasions are considered to be one of the greatest threats to the integrity of most ecosystems on earth. This volume explores the current state of marine bioinvasions, which have been growing at an exponential rate over recent decades. Focusing on the ecological aspects of biological invasions, it elucidates the different stages of an invasion process, starting with uptake and transport, through inoculation, establishment and finally integration into new ecosystems. Basic ecological concepts - all in the context of bioinvasions - are covered, such as propagule pressure, species interactions, phenotypic plasticity, and the importance of biodiversity. The authors approach bioinvasions as hazards to the integrity of natural communities, but also as a tool for better understanding fundamental ecological processes. Important aspects of managing marine bioinvasions are also discussed, as are many informative case studies from around the world.
