HPO42-, H2PO4-, FeHPO4 (aq), MgHPO4 (aq), CaHPO4 (aq), MnHPO4 (aq), FeH2PO4+, CaH2PO4+, and CaPO4- were major compounds of P in the soil solution in the Pine Rockland. Prescribed fire significantly increased extractable concentrations of these P compounds after14 days, except for FeH2PO4+. Within a relatively low P availability, solubility of P in the soil solution was controlled by vivianite and MnHPO4, and undersaturated with Ca/Mg-P minerals. Changes of ionic activities in the soil solution following the fire shifted equilibrium of P between vivianite and MnHPO4.
At the heart of evolution lies a bewildering paradox. Natural selection favors above all the individual that leaves the most offspring—a superorganism of sorts that Jonathan Silvertown here calls the "Darwinian demon." But if such a demon existed, this highly successful organism would populate the entire world with its own kind, beating out other species and eventually extinguishing biodiversity as we know it. Why then, if evolution favors this demon, is the world filled with so many different life forms? What keeps this Darwinian demon in check? If humankind is now the greatest threat to biodiversity on the planet, have we become the Darwinian demon? Demons in Eden considers these questions using the latest scientific discoveries from the plant world. Readers join Silvertown as he explores the astonishing diversity of plant life in regions as spectacular as the verdant climes of Japan, the lush grounds of the Royal Botanical Gardens at Kew, the shallow wetlands and teeming freshwaters of Florida, the tropical rainforests of southeast Mexico, and the Canary Islands archipelago, whose evolutionary novelties—and exotic plant life—have earned it the sobriquet "the Galapagos of botany." Along the way, Silvertown looks closely at the evolution of plant diversity in these locales and explains why such variety persists in light of ecological patterns and evolutionary processes. In novel and useful ways, he also investigates the current state of plant diversity on the planet to show the ever-challenging threats posed by invasive species and humans. Bringing the secret life of plants into more colorful and vivid focus than ever before, Demons in Eden is an empathic and impassioned exploration of modern plant ecology that unlocks evolutionary mysteries of the natural world.
Between roughly 25 and 31 degrees north latitude, a combination of flat topography, poor soils, and limited surface water produce deserts nearly everywhere on earth. In Florida, however, these conditions support a lavish biota, more diverse than that of any other state east of the Mississippi. In this first comprehensive guide to the state's natural resources in sixty years, thirty top scholars describe the character, relationships, and importance of Florida's ecosystems, the organisms that inhabit them, the forces that maintain them, and the agents that threaten them. From pine flatwoods to coral reef, Ecosystems of Florida provides a detailed, comprehensive, authoritative account of the peninsular state's complex, fragile environments.
This book draws together the latest findings on the hydrological processes, community organization, and stress physiology of freshwater, tidally influenced land-margin forests of the southeastern United States. It describes the land use history that led to the restricted distribution of these wetlands, and provides descriptions of the hydrology, soils, biogeochemistry, and physiological ecology of these systems, highlighting the similarities shared among tidal freshwater forested wetlands.
Providing a synthesis of basic and applied research, The Everglades, Florida Bay, and Coral Reefs of the Florida Keys: An Ecosystem Sourcebook takes an encyclopedic look at how to study and manage ecosystems connected by surface and subsurface water movements. The book examines the South Florida hydroscape, a series of ecosystems linked by hydrolog
Forgotten Grasslands of the South is the study of one of the biologically richest and most endangered ecosystems in North America. In a seamless blend of science and personal observation, renowned ecologist Reed Noss explains the natural history of southern grasslands, their origin and history, and the physical determinants of grassland distribution, including ecology, soils, landform, and hydrology. In addition to offering fascinating new information about these little-studied ecosystems, Noss demonstrates how natural history is central to the practice of conservation. Although theory and experimentation have recently dominated the field of ecology, ecologists are coming to realize how these distinct approaches are not divergent but complementary, and that pursuing them together can bring greater knowledge and understanding of how the natural world works and how we can best conserve it. This long-awaited work sets a new standard for scientific literature and is essential reading for those who study and work to conserve the grasslands of the South as well as for everyone who is fascinated by the natural world.
Florida's climate has been and continues to be one of its most important assets. It has enabled the growth of many major industries, including tourism and agriculture, which now rank at the top of Florida's diverse economic activities. Our state's climate enables its native ecosystems to flourish and attract citizens from around the world. The dependencies of Florida's society and ecosystems on climate are widely recognized and generally taken for granted. However, we now know that climate around the world is changing. Questions arise about whether or not Florida's climate is changing, how rapidly these changes might occur, and how Florida may adapt to anticipated changes and help mitigate the rates of change. This book provides a thorough review of the current state of research on Florida's climate, including physical climate benchmarks; climate prediction, projection, and attribution; and the impacts of climate and climate change on the people and natural resources of Florida. The editors have gathered more than 90 researchers at universities across the state and beyond to address important topics such as sea level rise, water resources, and how climate affects various sectors, including energy, agriculture, forestry, tourism, and insurance. This volume offers accessible, accurate information for students, policymakers, and the general public. About the Editors: Eric P. Chassignet is a professor in the Department of Earth, Ocean and Atmospheric Science and director of the Center for Ocean-Atmospheric Prediction Studies at Florida State University. James W. Jones is a distinguished professor emeritus in the Department of Agricultural and Biological Engineering at the University of Florida.
