Download or read book Population Characteristics and Trophic Interactions Between Pacific Mole Crabs and Redtail Surfperch on Northern California Sandy Beaches written by Michelle L. Succow and published by . This book was released on 2017 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: A network of marine protected areas (MPAs) was established to protect northern California coastal habitats in December 2012. Populations of two indicator species, Amphistichus rhodoterus (redtail surfperch) and Emerita analoga (pacific mole crabs) were characterized within MPAs and reference sites to provide baseline ecological information for this region. Data were gathered using a series of simple field surveys (hook and line fishing surveys for A. rhodoterus along with core and transect surveys for E. analoga). Relative abundance, lengths, and sex ratios of A. rhodoterus did not differ between MPAs and their respective reference sites, whereas condition (overall health) increased in a north to south trend. Although based on a limited number of tag returns, movement of A. rhodoterus within northern California appears to be relatively local. Relative swash zone abundance of E. analoga did not differ between the MPA studied and its respective reference sites. Abundance and biomass of small-sized (10 mm) E. analoga greatly increased during the summer months, likely due to recruitment to northern California beaches. A similar trend occurred for medium and large-sized crabs during spring months, likely due to the timing of reproduction in this region. Both species serve as good indicator species for the northern California region. However, future monitoring for E. analoga should be based on timing of reproduction and recruitment.

Download or read book Coastal Watershed Management written by A. Fares and published by WIT Press. This book was released on 2008-05-23 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal watersheds differ from others by their unique features, including proximity to the ocean, weather and rainfall patterns, subsurface features, and land covers. Land use changes and competing needs for valuable water and land resources are especially more distinctive to such watersheds. This book covers recent research relevant to coastal watersheds. It addresses the impact of a stream’s chemical, biological, and sediment pollutants on the quality of the receiving waters, such as estuaries, bays, and near-shore waters. The contents of the book can be divided into three sections; a) overview of hydrological modelling, b) water quality assessment, and c) watershed management. This book differs from other hydrology books by dealing with coastal watersheds which are characterized by their unique features: including weather and rainfall patterns, subsurface characteristics, and land use and cover. In addition to academia, the book should be of interest to organizations concerned with watershed management, such as local and federal governments and environmental groups. Overall, the book is expected to satisfy a great need toward understanding and managing critical areas in many parts of the world.
