Book Synopsis When Do Propagules Matter? by : Jason Edward Willand
Download or read book When Do Propagules Matter? written by Jason Edward Willand and published by . This book was released on 2014 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological restoration aims to augment and steer the composition and contribution of propagules for community regeneration in degraded environments. Three studies were conducted to elucidate the role of regeneration dynamics and dominant species on community assembly during tallgrass prairie restoration. In the first study, patterns in the abundance, richness, and diversity of seed and bud banks were quantified across an 11-year chronosequence of restored prairies and in prairie remnants to elucidate the degree to which the germinable seed bank, emerged seedlings, belowground buds, and emerged ramets were related to community regeneration. There were no directional patterns in the abundance, richness, or diversity of the germinable seed bank across the chronosequence. Emerged seedling abundance of sown species decreased during restoration, whereas richness and diversity of all emerged seedlings and non-sown emerged seedling species decreased across the chronosequence. Conversely, abundance and richness of belowground buds increased with restoration age and belowground bud diversity of sown species increased across the chronosequence. Numbers of emerged ramets also increased across the chronosequence and was driven primarily by the number of graminoid ramets. There were no temporal changes in abundance and richness of sown and non-sown emerged ramets, but diversity of sown emerged ramets increased across the chronosequence. This study demonstrates that after initial seeding, plant community structure in restored prairies increasingly reflects the composition of the bud bank. In the second study, abundance and richness of ramets, emerged seedlings, seed rain, and the soil seed bank were measured in a restoration experiment consisting of a split plot design with population source of dominant grasses (cultivar vs. local ecotype) and sown subordinate species (three unique pools of non-dominant species) as the subplot factor, respectively. Different sown species pools were included to assess whether any observed differences in propagule abundance or richness between the dominant species sources was generalizable across varying interspecific interactions. Abundance of emerged ramets was similar between communities sown with cultivar and local ecotypes of the dominant grasses but differed among sown species pools in prairie restored with cultivars but not local ecotypes. Number of emerged seedlings also differed among species pools, but only in communities sown with local ecotypes of the dominant grasses. There was also higher seedling emergence in communities sown with local ecotypes relative to cultivars of the dominant grasses in one species pool. Richness of the seed rain was influenced by an interaction between dominant grass population source and sown species pool, resulting from (1) higher richness in prairie restored with local ecotypes than cultivars of the native grasses in one species pool and (2) differences in richness among species pools that occurred only in prairie restored with the local ecotype grass source. Abundance and richness of the seed bank was not affected dominant grass population source. This study addressed a poorly understood potential effect of using cultivars in ecological restoration, specifically on the abundance and supply of propagules for community assembly. These results suggest that if both local ecotype and cultivar sources are available for restoration, using local ecotypes could result in more seedling germination and richness in the seed rain. One of the central concepts of ecology is to understand the processes that influence species diversity, and how the resulting diversity affects ecosystem functioning. Diversity has been hypothesized to be responsible for long-term community stability, contrasted by the idea that dominant species regulate temporal stability (mass ratio hypothesis). In the third study, community metrics (total plant cover, forb cover, C4 grass cover, richness, and diversity) were measured in a restoration experiment consisting of a split plot design with sown dominant grasses (Andropogon gerardii, Schizachyrium scoparium, and Sorghastrum nutans) and subordinate species (three unique pools of non-dominant species) as the subplot factor, with treatment (control vs. suppression of dominant grasses) as the sub-subplot factor, respectively. Dominant grass suppression had little effect on forb cover, richness, and diversity, but influenced total and C4 grass cover. Propagule addition increased community richness and diversity in year of sowing and year after sowing, but contributed little to total cover. Dominant grass suppression had an effect on new species recruitment in one of two species pools, with suppression of all dominant grasses having the greatest influence on total cover and richness of new species. These results suggest that dominant species collectively are responsible for modulating stable species composition during community assembly and can act as a biotic filter to the recruitment of new species, but diverse subordinate species assemblages are more important for temporal stability.

Book Synopsis Experimental Techniques in Plant Disease Epidemiology by : Jürgen Kranz
Download or read book Experimental Techniques in Plant Disease Epidemiology written by Jürgen Kranz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most books on epidemiology have treated the subject from a statistical, mathematical or computer applicational point of view. However, experiments must be performed first to provide the data for models which in turn can then be proven by further experimentation. This mutual interplay of theory and empirics gives epidemiology its scientific thrust and charm. This book provides a choice of methods for varying applications and objectives, covering all important aspects for the designing of experiments. Furthermore, the reader is supplied with solutions to his experimental problems and many "tricks of the trade". The newcomer to the field will also profit by this methodology guide.

Available in PDF, EPUB and Kindle. Book excerpt: Andrea Bottani Massimiliano Carrara Pierdaniele Giaretta What do we do when we do metaphysics? The aim of this introduction is to give a provisional answer to this question, and then to explain the subtitle of the volume. It is easy to observe that when we do meta physics we engage in a linguistic activity, mainly consisting of uttering declarative sentences that are not very clear to most people. That is true, but, of course, it is not very informative. What do we speak of when we do metaphysics? A traditional answer could be: we speak of what things really are, so suggesting that things can appear in a way that is different from the way they really are. So understood, meta physics is about the sense, or the senses, of "real being". A question that immediately arises is whether the sense of being is unique or is different for different types of things. Another question is whether it is possible that something could appear to be, but really not be. Modem analytic metaphysicians usually answer that the sense of being is unique, while acknowledging that there are different kinds of things, and that to say that something could appear to be but really not be is a plain contradiction, unless what is understood is that it could appear to us that there is something having such and such features, but viii Individuals, Essence, and Identity really there is no such a thing.

Book Synopsis How Things Might Have Been by : Penelope Mackie
Download or read book How Things Might Have Been written by Penelope Mackie and published by Oxford University Press. This book was released on 2006-04-27 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: How are we to distinguish between the essential and accidental properties of things such as individual people, cats, trees, and tables? Almost everyone agrees that such individuals could have been different, in certain respects, from the way that they actually are. But what are the respects in which they could not have been different: which of their properties are essential to their being the individuals that they are? And why? Following the revival of interest among analytic philosophers in essentialism and de re modality generated by the work of Kripke and others in the 1970s, these questions have been the subject of intense, yet still unresolved, debate. In this book, Penelope Mackie challenges most of the answers that have been given to these questions. Via a critical examination of rival theories, she arrives at what she calls 'minimalist essentialism', an unorthodox theory according to which ordinary individuals have relatively few interesting essential properties, and intuitions that appear to support stronger versions of essentialism are interpreted as consistent with the theory. The topics discussed include the rivalry between the interpretation of de re modality in terms of 'identity across possible worlds' and its interpretation in terms of David Lewis's counterpart theory, some notorious modal puzzles generated by the theory that individuals exist with different properties in different possible worlds, the notion of an individual essence, Kripke's 'necessity of origin' thesis, and the widely held view that there are sortal properties that are essential properties of the things to which they belong. The book also includes a discussion of the relation between essentialism about individuals and essentialism about natural kinds, and a critical examination of the connection between semantics and natural kind essentialism.

Download or read book Postharvest Pathogens and Disease Management written by P. Narayanasamy and published by John Wiley & Sons. This book was released on 2005-12-07 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: POSTHARVEST PATHOGENS AND DISEASE MANAGEMENT Postharvest diseases caused by microbial pathogens account for millions of dollars in losses of both durable and perishable produce products every year. Moreover, with consumers increasingly demanding minimally processed vegetables and fruits--which can be invaded by human pathogens--there is an imperative need for suitable protective measures to provide pathogen-free commodities that are free from, or contain only acceptable levels of, chemical residues. Providing details of both conventional and modern molecular techniques applicable for the detection, identification, and differentiation of field and storage microbial pathogens, Postharvest Pathogens and Disease Management: * Discusses diseases of both durables and perishables during transit and storage * Provides a basic understanding of the effects of handling and storage practices as well as field conditions and product susceptibility on the development of postharvest diseases * Reveals, as a cautionary note, the potential hazards of mycotoxins with carcinogenic properties that can contaminate fruits and vegetables * Contains detailed information derived from elucidative evidence and disease data in order to explain the infection process and subsequent stages of disease development * Helps readers to avoid conditions that favor disease incidence and spread * Includes real life examples of disease management strategies to help readers develop effective disease management systems suitable for different ecosystems * Emphasizes the importance of integrating several different effective methods in tandem, including the development of cultivars with resistance to postharvest diseases; the selection of suitable analytical methods; and the effective use of biocontrol agents and chemicals * Presents protocols for numerous techniques and basic methods, making the book a distinctive and highly useful teaching and research tool Postharvest Pathogens and Disease Management offers readers insight into the principles and methods of avoiding and managing postharvest diseases of fruit and vegetable products in an efficient, economical, and environmentally feasible manner, allowing producers to sell safer, higher-quality produce to the public and prevent the losses associated with postharvest disease.
