This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Although fire severity has been shown to be a key disturbance to stream-riparian ecosystems in temperate zones, the effects of fire-severity on stream-riparian structure and function in Mediterranean-type systems remains less well resolved. Mediterranean ecosystems of California are characterized by high interannual variability in precipitation and susceptibility to frequent high-intensity wildfires. From 2011 to 2014, I utilized a variety of experimental designs to investigate the influence of wildfire across 70 study reaches on stream-riparian ecosystems in Yosemite National Park (YNP), located in the central Sierra Nevada, California, USA. At 12 stream reaches paired by fire-severity, I measured riparian community composition and structure, stream geomorphology, density and community composition of benthic macroinvertebrates, and density, trophic position, mercury (Hg) body loading, and reliance on aquatically-derived energy of/by spiders of the family Tetragnathidae, a common riparian spider that relies heavily on emergent aquatic insect prey. In addition, along a gradient of drainage area in two rivers, I measured the relative effects of ecosystem size, flood magnitude, productivity, and wildfire on trophic position and reliance on aquatically-derived energy of/by benthic insect predators and tetragnathid spiders. Aquatic birds like the American dipper (Cinclus mexicanus) are considered landscape integrators and are constrained by different ecological processes than aquatic organisms, therefore assessment of the trophic dynamics of aquatic-obigate birds may illuminate divergent patterns related to both fire and food-web dynamics. I estimated reliance on aquatically-derived energy and trophic position of dippers in 27 mountain streams and estimated the relative explanatory power of ecosystem size, precipitation, and wildfire as predictors of dipper trophic dynamics. Taken together, the results of my study, combined with the long period of time since fire at some study reaches, indicate support for interactions between wildfire and climate across complex spatial and temporal scales as drivers of stream-riparian ecosystem responses to wildfire.

Available in PDF, EPUB and Kindle. Book excerpt: This long-anticipated reference and sourcebook for CaliforniaÕs remarkable ecological abundance provides an integrated assessment of each major ecosystem typeÑits distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of CaliforniaÕs ecological patterns and the history of the stateÕs various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the stateÕs ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of CaliforniaÕs environment and curious naturalists.

This book was released on 2020-10-01 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: California and other wildfire-prone western states have experienced a substantial increase in the number and intensity of wildfires in recent years. Wildlands and climate experts expect these trends to continue and quite likely to worsen in coming years. Wildfires and other disasters can be particularly devastating for vulnerable communities. Members of these communities tend to experience worse health outcomes from disasters, have fewer resources for responding and rebuilding, and receive less assistance from state, local, and federal agencies. Because burning wood releases particulate matter and other toxicants, the health effects of wildfires extend well beyond burns. In addition, deposition of toxicants in soil and water can result in chronic as well as acute exposures. On June 4-5, 2019, four different entities within the National Academies of Sciences, Engineering, and Medicine held a workshop titled Implications of the California Wildfires for Health, Communities, and Preparedness at the Betty Irene Moore School of Nursing at the University of California, Davis. The workshop explored the population health, environmental health, emergency preparedness, and health equity consequences of increasingly strong and numerous wildfires, particularly in California. This publication is a summary of the presentations and discussion of the workshop.
