This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objectives of the present study were to 1) analyze genetic variability of Q. rubra populations from the mining region of Sudbury (Ontario) using RAPD marker system and 2) analyze the expression of nickel and copper resistance genes in Q. rubra populations. The level of polymorphic loci within populations was high ranging from 61 % to 72% despite a high level of gene flow (2.4) and the population differentiation (GST) value was low (0.17). All Q. rubra populations analyzed were genetically sustainable. Moreover, this study revealed that all populations were genetically closely related with genetic distance values varying from 0.17 to 0.35. A zinc finger protein of Arabidopsis thaliana (ZAT11) involved in nickel resistance was differentially expressed in samples analyzed. There was a 120x up-regulation of ZAT11 expression in samples from metal contaminated areas of Wahnapitae Dam compared to other sites. No association between soil metal levels and expression of ZAT11 was established.

Lind-Riehl and published by . This book was released on 2014 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest trees, like oaks, rely on high levels of genetic variation to adapt to varying environmental conditions. Thus, genetic variation and its distribution are important for the long-term survival and adaptability of oak populations. Climate change is projected to lead to increased drought and fire events as well as a northward migration of tree species, including oaks. Additionally, decline in oak regeneration has become increasingly concerning since it may lead to decreased gene flow and increased inbreeding levels. This will in turn lead to lowered levels of genetic diversity, negatively affecting the growth and survival of populations. At the same time, populations at the species' distribution edge, like those in this study, could possess important stores of genetic diversity and adaptive potential, while also being vulnerable to climatic or anthropogenic changes. A survey of the level and distribution of genetic variation and identification of potentially adaptive genes is needed since adaptive genetic variation is essential for their long-term survival.

Download or read book Regeneration of Red Oak Quercus Rubra L Using Shelterwood Systems written by Dan Dey and published by Sault Ste. Marie : Ontario Ministry of Natural Resources. This book was released on 1996 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this report is to review the scientific literature on red oak biology and silviculture as it pertains to the use of shelterwood systems in oak regeneration and management. Sections of the report describe oak ecophysiology and succession; growth characteristics; environmental requirements (light, water, nutrients, temperature) and response to stress (pests, competition); and oak regeneration ecology (acorn production and dispersal, seeding and germination requirements, artificial regeneration). The final section reviews oak management by shelterwood systems, including prescriptions for residual overstory, control of understory vegetation, stocking targets, and final overstory removal.

Download or read book Ecological Regions of North America written by and published by . This book was released on 1997 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.

Available in PDF, EPUB and Kindle. Book excerpt: In the course of evolution, a great variety of root systems have learned to overcome the many physical, biochemical and biological problems brought about by soil. This development has made them a fascinating object of scientific study. This volume gives an overview of how roots have adapted to the soil environment and which roles they play in the soil ecosystem. The text describes the form and function of roots, their temporal and spatial distribution, and their turnover rate in various ecosystems. Subsequently, a physiological background is provided for basic functions, such as carbon acquisition, water and solute movement, and for their responses to three major abiotic stresses, i.e. hard soil structure, drought and flooding. The volume concludes with the interactions of roots with other organisms of the complex soil ecosystem, including symbiosis, competition, and the function of roots as a food source.

Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the 2nd edition, there have been substantial developments in the field of litter decomposition. This fully revised and updated 3rd edition of Plant Litter reflects and discusses new findings and re-evaluates earlier ones in light of recent research and with regard to current areas of investigation. The availability of several long-term studies allows a more in-depth approach to decomposition patterns and to the later stages of decomposition, as well as to humus formation and accumulation. The latest information focuses on three fields: - the effects of manganese on decomposition and possibly on carbon sequestration, - new findings on decomposition dynamics, and - the new analytical technique using 13C-NMR.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides case studies and general views of the main processes involved in the ecosystem shifts occurring in the high mountains and analyses the implications for nature conservation. Case studies from the Pyrenees are preponderant, with a comprehensive set of mountain ranges surrounded by highly populated lowland areas also being considered. The introductory and closing chapters will summarise the main challenges that nature conservation may face in mountain areas under the environmental shifting conditions. Further chapters put forward approaches from environmental geography, functional ecology, biogeography, and paleoenvironmental reconstructions. Organisms from microbes to large carnivores, and ecosystems from lakes to forest will be considered. This interdisciplinary book will appeal to researchers in mountain ecosystems, students and nature professionals. This book is open access under a CC BY license.
