Modern Trends in Diatom Identification


Book Description

High-resolution images of phytoplankton cells such as diatoms or desmids, which are useful for monitoring water quality, can now be provided by digital microscopes, facilitating the automated analysis and identification of specimens. Conventional approaches are based on optical microscopy; however, manual image analysis is impractical due to the huge diversity of this group of microalgae and its great morphological plasticity. As such, there is a need for automated recognition techniques for diagnostic tools (e.g. environmental monitoring networks, early warning systems) to improve the management of water resources and decision-making processes. Describing the entire workflow of a bioindicator system, from capture, analysis and identification to the determination of quality indices, this book provides insights into the current state-of-the-art in automatic identification systems in microscopy.










Identifying Marine Phytoplankton


Book Description

Identifying Marine Phytoplankton is an accurate and authoritative guide to the identification of marine diatoms and dinoflagellates, meant to be used with tools as simple as a light microscope. The book compiles the latest taxonomic names, an extensive bibliography (referencing historical as well as up-to-date literature), synthesis and criteria in one indispensable source. Techniques for preparing samples and containing are included as well as hundreds of detailed, helpful information. Identifying Marine Phytoplankton is a combined paperback edition made available by popular demand of two influential books published earlier--Marine Phytoplankton and Identifying Marine Diatoms and Dinoflagellates. - Contains hundreds of illustrations showing critical characteristics necessary for proper identification, plus keys and other guides - Provides up-to-date taxonomic revisions - Includes species from around the world - Updates synthesis of modern and historical literature presented by active researchers in the field - Compiles literature from around the world into one handy source










A Pleistocene Diatom Assemblage from Ellesmere Island, Northwest Territories


Book Description

Diatom analysis of a Pleistocene sediment sample from Cape Storm, Ellesmere Island, dated at 35,000 to 43,000 radiocarbon years, resulted in the identification and ecological characterization of 136 taxa. The diatom thanatocoenosis represents a littoral constituent marked by the preponderance of benthic and epontic species and a neritic component manifested by meroplanktonic forms with cryophilic diatoms and stenothermal taxa. Floristic analysis indicates that deposition occurred in a shallow coastal marine environment having lowered salinities and cold water conditions influenced by ice.
