Sea Urchins


Book Description

Sea Urchins: Biology and Ecology, Fourth Edition, Volume 43 expands its coverage to include the entire class of Echinoidea, making this new edition an authoritative reference of the entire class of species. This is a valuable resource that will help readers gain a deep understanding of the basic characteristics of sea urchins, the basis of the great variation that exists in sea urchins, and how sea urchins are important components of marine ecosystems. Updated coverage includes sections on reproduction, metabolism, endocrinology, larval ecology, growth, digestion, carotenoids and disease.







Natural History Guide to the Northwestern Gulf of California and Adjacent Desert


Book Description

This field guide can be used both by students and the general public. Many of the illustrations reflect what a person would see in the real world (e.g. a jackrabbit in the distance instead of close up or silhouettes of birds in flight). The manuscript is divided into the following areas: a. an introduction the Northern Gulf of California with a brief discussion of the local environments, their geology and climate, b) a systematic overview and survey of the diversity of animal and plant groups that are discussed in the book, and c) the guide to the common animal and plant species with the focus on habitats.




The Edge of the Sea of Cortez


Book Description

"The Sea of Cortez, also known as the Gulf of California, is framed by the Mexican mainland states of Sonora and Sinaloa and the peninsula states of Northern and Southern Baja California. Once called the Vermillion Sea, its long, narrow shape results in tidal extremes that provide a unique home for a rich diversity of marine life. Its beautiful water sustains those who live along its shores, entices tourists from all over the world, and beckons marine scientists to discover its secrets."--BOOK JACKET.










Late Cenozoic Drainage History of the Southwestern Great Basin and Lower Colorado River Region


Book Description

Papers in this title were selected from presentations from an April 2005 workshop sponsored by the U.S. Geological Survey Earth Surface Dynamics Program, the U.S. Geological Survey National Cooperative Geologic Mapping Program, and the Smithsonian Institution. Papers are divided into two broad topics of the configuration, areal extent, and temporal development of the chain of interconnected lakes that emptied into Death Valley during periods of the Pleistocene, and the late Cenozoic history of drainage integration in the lower Colorado River region. Papers are occasionally illustrated in both color and black-and-white; the publication contains no index.




Biodiversity and the Management of the Madrean Archipelago


Book Description

This conference brought together scientists and managers from government, universities, and private organizations to examine the biological diversity and management challenges of the unique "sky island" ecosystems of the mountains of the southwestern U.S. and northwestern Mexico. Session topics included: floristic resources, plant ecology, vertebrates, invertebrates, hydrology and riparian systems, aquatic resources, fire, conservation and management, human uses through time, and visions for the future. Illustrated.







Geologic Excursions in Southwestern North America


Book Description

"Over the course of his 43-year career, James C. Knox conducted seminal research on the geomorphology of the Driftless Area of southwestern Wisconsin. His research covered wide-ranging topics such as long-term land-scape evolution in the Driftless Area; responses of floods to climate change since the last glaciation; processes and timing of floodplain sediment deposition on both small streams and on the Mississippi River; impacts of European settlement on the landscape; and responses of stream systems to land-use changes. This volume pre-sents the state of knowledge of the physical geography and geology of this unglaciated region in the otherwise-glaciated Midwest with contributions written by Knox prior to his passing in 2012 and by numerous of his for-mer colleagues and graduate students"--
