Ecohydraulics
Author: Ian Maddock
Publisher: John Wiley & Sons
ISBN: 1118526740
Category : Technology & Engineering
Languages : en
Pages : 659
Book Description
Ecohydraulics: An Integrated Approachprovides a research level text which highlights recent developments of this emerging and expanding field. With a focus on interdisciplinary research the text examines:- the evolution and scope of ecohydraulics interactions between hydraulics, hydrology, fluvial geomorphology and aquatic ecology the application of habitat modelling in ecohydraulic studies state of the art methodological developments and approaches detailed case studies including fish passage design and the management of environmental flow regimes research needs and the future of ecohydraulics research The contributions offer broad geographic coverage to encapsulate the wide range of approaches, case studies and methods used to conduct ecohydraulics research. The book considers a range of spatial and temporal scales of relevance and aquatic organisms ranging from algae and macrophytes to macroinvertebrates and fish. River management and restoration are also considered in detail, making this volume of direct relevance to those concerned with cutting edge research and its application for water resource management. Aimed at academics and postgraduate researchers in departments of physical geography, earth sciences, environmental science, environmental management, civil engineering, biology, zoology, botany and ecology; Ecohydraulics: An Integrated Approach will be of direct relevance to academics, researchers and professionals working in environmental research organisations, national agencies and consultancies.

Frogs of the United States and Canada
Author: C. Kenneth Dodd Jr.
Publisher: JHU Press
ISBN: 1421444917
Category : Nature
Languages : en
Pages : 991
Book Description
"The premiere reference book on the 108 species of frogs inhabiting North America north of Mexico. An unparalleled synthesis of the biology and behavior of all native and nonindigenous species, this two-volume, extensively referenced resource has been called the most important book ever published on North American anura. Color photographs and range maps accompany species accounts detailing information on etymology, nomenclature, identification, distribution, fossil record, systematics and geographic variation, life history and ecology, behavior, population and community biology, and conservation. This new edition of the text contains the following updates: Literature citations have been added from 2012 to 2021, now spanning from 1709 to 2021. Distribution maps have been updated, recording the decreased ranges due to declining amphibian populations. Photographs have been revised to ensure the highest digital quality. Anaxyrus williamsi and Lithobates kauffeldi, newly described species, have been included. An account is also included for Gastrophryne mazatlanensis, now recognized as occurring within the United States. Generic keys have been added. A brief section on N.A. frogs in history and art have been added. Nomenclature has been updated (Incilius for Ollotis). Now the only up-to-date and comprehensive resource for those trying to protect amphibians in the US and Canada, as well as for researchers and wildlife managers who study biodiversity"--

Identification of Foothill Yellow-legged Frog Individuals Through Automated Pattern Recognition

Pages : 104
Book Description
Photographic identification of individuals using natural physical markings provides important information for studying wildlife population demographics. The Foothill Yellow-legged Frog (Rana boylii, FYLF) is a species with unique chin-spot patterns that researchers currently identify through manual comparison of photographs in search of matching markings. However, these commonly employed methods, which can involve manually comparing many hundreds of images, are both time consuming and potentially inaccurate. In this project, we address this problem by defining a process that automates the identification of FYLF individuals from images using MATLAB-based image processing and pattern recognition techniques. We tested the process using replica frogs with patterns based on actual FYLF chin-spot patterns. This method effectively found matches in frogs when the individual spots had complex shapes. However, the process less effectively recognized patterns that were based primarily on spot location. This project provides several valuable tools researchers can use to identify FYLF individuals and can be the foundation for a more optimal system.
