    Abstract: The goal of this book is to convey the rich perspectives, principles, and enchantment of ecology to a broad audience of students and lifelong learners. The book is based on the belief that the science of ecology is best understood by examining familiar ecosystems from the natural world and weaving fresh insights and ecological concepts into an ecosystems framework to reveal the patterns, processes, and interactions that are the foundation of sustainable living systems in our biosphere. In the spirit of that teaching philosophy, the core of this book focuses on specific ecosystems that are familiar to most of us (e.g., forests, wetlands, streams, lakes, and the like). Taken as a whole, the chapters of this text are intended to provide a conceptual framework and an intellectual pathway for understanding and interpreting the ecology of the biosphere using elements of population, community, ecosystem, and landscape ecology. Equipped with this toolkit of ecological literacy, readers and students will hopefully be better prepared to make personal, business, and civic or governmental decisions that are consistent with a healthy and sustainable Earth.

    Notes: Summary Studies were conducted with coniferous forest floor microcosms to examine the potential influence of acid precipitation, temperature changes, and plant uptake upon the chemistry of soil leachate solutions. The experimental design included two temperatures and three different simulated throughfall chemistry treatments. When the acidity of throughfall inputs to the microscosms increased, the forest floors exhibited increased leaching losses of calcium, magensium, potassium, and ammonium. The fact that aluminum losses did not incrase correspondingly suggested that there may be a kinetic lag in the mobilization and leaching of aluminum. When microcosms were exposed to warmer temperatures, percolates showed increased leaching losses of calcium, potassium, ammonium, sulfate, nitrate, and organic anions. Forest floor microcosms exposed to simulated average field conditions behaved very much like field plots under the same environmental conditions; however, there were predictable differences in leaching losses between laboratory and field systems for those ions which are strongly controlled by plant uptake. In general, the exclusion of plant uptake from microcosms resulted in increased leaching of potassium, nitrate, ammonium. and sulfate relative to field plots.

    Notes: Summary This comparative soil microcosm study examined the effects of precipitation acidity on decomposition processes in three contrasting eastern North American forest soils: a Becket series Haplorthod, an Unadilla series Dystrochrept, and an Adams series Haplorthod. Results from all three soils showed that soil respiration is quantitatively unaffected by differences in precipitation acidity over the range of pH 5.7 to 3.5 (annual loading rates of 36 to 5,520 eq H+ · ha−1). Soil respiration did vary as a function of edaphic differences between soils. Data from all three soils also indicated that precipitation acidity (at pH≧3.5 and lime potential ≧1.11) had no consistent quantitative effect upon total dissolved organic carbon leaching. Again, differences in DOC flux were related to inter-soil edaphic variations. Carbon turnover budgets for the three soils indicated that 54–68% of the forest floor carbon loss occurred through respiration, while DOC leaching accounted for the remaining 32–46% of carbon loss. Finally, results from all three soils showed that increased inputs of strong acids to the forest floor caused distinct decreases in the hydrophobic acid (fulvic acid) content of leachate dissolved organic carbon.
