Available in PDF, EPUB and Kindle. Book excerpt: We characterised the remarkable heterogeneity following the large, severe fires of 1988 in Yellowstone National Park (YNP), in the northern Rocky Mountains, Wyoming, USA, by focussing on spatial variation in post-fire structure, composition and ecosystem function at broad, meso, and fine scales. Ecological heterogeneity at multiple scales may enhance resilience to large, severe disturbances by providing structural, biological and functional redundancy. Post-fire heterogeneity in stand age, coarse wood abundance, microbial and understorey communities reflected interactions between existing pre-fire patterns and fire severity at different scales, suggesting that environmental context plays an important role in successional responses to large fires. In response to these post-fire patterns, heterogeneity in carbon (C) and nitrogen (N) storage, N mineralisation, decomposition, and prductivity was also evident at multiple scales and may confer resiliency to large fires. For example, at broad scales, C storage in YNP appears resistant to changes in age-class structure associated with large stand-replacing fires. In summary, the YNP landscape is recovering rapidly from the 1988 fires through natural mechanisms, owing to the abundance and spatial heterogeneity of post-fire residuals, but other systems with fewer biotic legacies may be less resilient to such large, severe fires.

Available in PDF, EPUB and Kindle. Book excerpt: Americans currently choose their president through the electoral college, an extraordinarily complex mechanism that may elect a candidate who does not receive the most votes. In this provocative book, George Edwards III argues that, contrary to what supporters of the electoral college claim, there is no real justification for a system that might violate majority rule. Drawing on systematic data, Edwards finds that the electoral college does not protect the interests of small states or racial minorities, does not provide presidents with effective coalitions for governing, and does little to protect the American polity from the alleged harms of direct election of the president. In fact, the electoral college distorts the presidential campaign so that candidates ignore most small states and some large ones and pay little attention to minorities, and it encourages third parties to run presidential candidates and discourages party competition in many states. Edwards demonstrates effectively that direct election of the president without a runoff maximizes political equality and eliminates the distortions in the political system caused by the electoral college.

Download or read book Forest Ecology written by Daniel M. Kashian and published by John Wiley & Sons. This book was released on 2023-01-16 with total page 788 pages. Available in PDF, EPUB and Kindle. Book excerpt: FOREST ECOLOGY Authoritative resource covering traditional plant ecology topics and contemporary components such as climate change, invasive species, ecosystem services, and more Forest Ecology provides comprehensive coverage of the field, focusing on traditional plant ecology topics of tree structure and growth, regeneration, effects of light and temperature on tree physiology, forest communities, succession, and diversity. The work also reviews abiotic factors of light, temperature, physiography (landforms and topography), soil, and disturbance (especially fire), and provides coverage of ecosystem-level topics including carbon storage and balance, nutrient cycling, and forest ecosystem productivity. The 5th edition of Forest Ecology retains the readability and accessibility of the previous editions and includes important additional topical material that has surfaced in the field. All topics are approached with a landscape ecosystem or geo-ecological view, which places biota (organisms and communities) in context as integral parts of whole ecosystems that also include air (atmosphere and climate), topography, soil, and water. As such, the book fills a niche utilized by no other forest ecology text on the market, helping students and researchers consider whole ecosystems at multiple scales. Sample topics covered in Forest Ecology include: Contemporary components of forest ecology, including climate change, invasive species, diversity, ecological forestry, landscape ecology, and ecosystem services. Characteristics of physiography important for forest ecosystems, including its effects on microclimate, disturbance, soil, and vegetation. Genetic diversity of woody plants and genecological differentiation of tree species, including the importance of hybridization, polyploidy, and epigenetics. Site quality estimation using tree height and ground flora, and multiple-factor approaches to forest site and ecosystem classification and mapping. Forest Ecology is a highly accessible text for students, but it also serves as an excellent reference for academics. In addition, practitioners of forest ecology can also harness the information within to gain better insight into the field for practical application of concepts.

Book Synopsis Monitoring Forest Regrowth Following Large Scale Fire Using Satellite Data by : Shannon Franks
Download or read book Monitoring Forest Regrowth Following Large Scale Fire Using Satellite Data written by Shannon Franks and published by . This book was released on 2013 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monitoring forest regrowth following major fires is important for understanding controls on forest regeneration and succession and detecting change in postfire plant communities. In this study we examined the extent to which forest regrowth following the 1988 Yellowstone National Park fires can be characterized by optical remote sensing data, and the spatial patterns associated with regrowth. Using a near-annual time series of Landsat satellite imagery, several satellite-based metrics were compared with field-based data of burn extent and post-fire stand structure and function. While there was little correlation between lodgepole pine density and our satellite metrics, single year regressions produced results over 80% and trend analysis of multiyear sites were able to explain 60 to 70% of the variability found between the ground collected data and the satellite metrics.

Book Synopsis Twenty-four Years After the Yellowstone Fires by : Monica Goigel Turner

Available in PDF, EPUB and Kindle. Book excerpt: Disturbance and succession have long been of interest in ecology, but how landscape patterns of ecosystem structure and function evolve following large disturbances is poorly understood. After nearly 25 years, lodgepole pine ( Pinus contorta var. latifolia) forests that regenerated after the 1988 Yellowstone Fires (Wyoming, USA) offer a prime opportunity to track the fate of disturbance-created heterogeneity in stand structure and function in a wilderness setting. In 2012, we resampled 72 permanent plots to ask (1) How have postfire stand structure and function changed between 11 and 24 yr postfire, and what variables explain these patterns and changes? (2) How has landscape-level (among-stand) variability in postfire stand structure and function changed between 11 and 24 yr postfire? We expected to see evidence of convergence beginning to emerge, but also that initial postfire stem density would still determine trajectories of biomass accumulation. After 24 yr, postfire lodgepole pine density remained very high (mean = 21,738 stems/ha, range = 0-344,067 stems/ha). Stem density increased in most plots between 11 and 24 yr postfire, but declined sharply where 11-yr-postfire stem density was >72,000 stems/ha. Stems were small in high-density stands, but stand-level lodgepole pine leaf area, foliage biomass, and live aboveground biomass increased over time and with increasing stem density. After 24 yr, mean annual lodgepole pine aboveground net primary production ( ANPP) was high (mean = 5 Mg?ha?1?yr?1, range = 0-16.5 Mg?ha?1?yr?1). Among stands, lodgepole pine ANPP increased with stem density, which explained 69% of the variation; another 8% of the variation was explained by environmental covariates. Early patterns of postfire lodgepole pine regeneration, which were contingent on prefire serotiny and fire severity, remained the dominant driver of stand structure and function. We observed mechanisms that would lead to convergence in stem density (structure) over time, but it was landscape variation in functional variables that declined substantially. Stand structure and function have not converged across the burned landscape, but our evidence suggests function will converge sooner than structure.

Available in PDF, EPUB and Kindle. Book excerpt: The earth's landscapes are being increasingly impacted by the activities of man. Unfortunately, we do not have a full understanding of the consequences of these disturbances on the earth's productive capacity. This problem was addressed by a group of French and U.S. ecologists who are specialists at levels of integration extending from genetics to the biosphere at a meeting at Stanford, California, sponsored by the National Science Foundation and the Centre National de la Recherche Scientifique. With a few important exceptions it was found at this meeting that most man-induced disturbances of ecosystems can be viewed as large scale patterns of disturbances that have occurred, generally on a small scale, in ecosystems through evolutionary time. Man has induced dramatic large-scale changes in the environment which must be viewed at the biosphere level. Acid deposition and CO increase are two 2 examples of the consequences of man's increased utilization of fossil fuels. It is a matter of considerable concern that we cannot yet fully predict the ecological consequences of these environmental changes. Such problems must be addressed at the international level, yet substantive mechanisms to do this are not available.
