Download or read book Positive Impact Forestry written by Thomas J. McEvoy and published by . This book was released on 2004-05 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Positive Impact Forestry is a primer for private woodland owners and their managers on managing their land and forests to protect both ecological and economic vitality. Moving beyond the concept of "low impact forestry," Thom McEvoy brings together the latest scientific understanding and insights to describe an approach to managing forests that meets the needs of landowners while at the same time maintaining the integrity of forest ecosystems. "Positive impact forestry" emphasizes forestry's potential to achieve sustainable benefits both now and into the future, with long-term investment superseding short-term gain, and the needs of families—especially future generations—exceeding those of individuals. Thom McEvoy offers a thorough discussion of silvicultural basics, synthesizing and explaining the current state of forestry science on topics such as forest soils, tree roots, form and function in trees, and the effects of different harvesting methods on trees, soil organisms, and sites. He also offers invaluable advice on financial, legal, and management issues, ranging from finding the right forestry professionals to managing for products other than timber to passing forest lands and management legacies on to future generations. Positive Impact Forestry helps readers understand the impacts of deliberate human activities on forests and offers viable strategies that provide benefits without damaging ecosystems. It speaks directly to private forest owners and their advisers and represents an innovative guide for anyone concerned with protecting forest ecosystems, timber production, land management, and the long-term health of forests. Named the "Best Forestry Book for 2004" by the National Woodlands Owners Association.
Download or read book Reproduction biology in grey wolves Canis lupus in Belarus Common beliefs versus reality written by Vadim Sidorovich and published by CHATYRY CHVERCI. This book was released on 2019-08-01 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: This scientific monograph gives a detailed information about reproduction biology in the grey wolf Canis lupus in Belarus. This topic includes the wolf breeding (mating and denning) behavior, fertility of the species and mortality of its pups. The initial material was not collected occasionally from wolf hunters and wolf pup searchers, but mainly gained by authors first-hand according to a well-set research design and long-term. By analyzing the gathered data, we became convinced that in the wolf reproduction biology there are more exceptions than rules. Therefore, the standard patterns of reproduction biology in wolves that are wide-spread in the published literature about the species we call as common beliefs that are given versus the wolf reality that we have found in Belarus. Concerning the non-standard features in the wolf reproduction biology, we revealed that multiple breeding in wolf pack is a common phenomenon, breeding of yearling females and wolf-dog hybridization were found to be irrespective the food base and strongly depending on the species population density i.e. they are reproduction regulations. Wolf pup mortality was investigated and the crucial role of deliberate predation of lynxes on wolf pups was revealed.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a solid scientific basis for researchers, practitioners and students interested in the application of genetic principles to tropical forest ecology and management. It presents a concise overview of genetic variation, evolutionary processes and the human impact on forest genetic resources in the tropics. In addition, modern tools to assess genetic diversity patterns and the dynamics of genetic structures are introduced to the non-specialist reader.
Download or read book Conifer Reproductive Biology written by Claire G. Williams and published by Springer Science & Business Media. This book was released on 2009-05-19 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: When it comes to reproduction, gymnosperms are deeply weird. Cycads and co- fers have drawn out reproduction: at least 13 genera take over a year from polli- tion to fertilization. Since they don’t apparently have any selection mechanism by which to discriminate among pollen tubes prior to fertilization, it is natural to w- der why such a delay in reproduction is necessary. Claire Williams’ book celebrates such oddities of conifer reproduction. She has written a book that turns the context of many of these reproductive quirks into deeper questions concerning evolution. The origins of some of these questions can be traced back Wilhelm Hofmeister’s 1851 book, which detailed the revolutionary idea of alternation of generations. This alternation between diploid and haploid generations was eventually to become one of the key unifying ideas in plant evolution. Dr. Williams points out that alter- tion of generations in conifers shows strong divergence in the evolution of male and female gametes, as well as in the synchronicity of male and female gamete development. How are these coordinated to achieve fertilization? Books on conifer reproduction are all too rare. The only major work in the last generation was Hardev Singh’s 1978 Embryology of Gymnosperms, a book that summarized the previous century’s work. Being a book primarily about embry- ogy, it stopped short of putting conifer reproduction in a genetic or evolutionary context.

Download or read book Sexual Reproduction of Tree Crops written by M. Sedgley and published by Academic Press. This book was released on 2013-10-22 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research into the reproductive biology of crop plants has expanded greatly in recent years and has lead to an increasing awareness of the importance of flowering, pollination, and fruit set in crop productivity. This book focuses specifically on tree cultivation. It deals with the basic biology of sexual reproduction and relates this to the practical aspects of tree crop breeding and orchard management for fruit and seed production, in both temperate and tropical species. It is aimed at both students and research scientists in horticulture, forestry, and pollination ecology as well as those working in tree breeding, tree cultivation, and orchard management. The conservation problems of rainforest regeneration in the tropics and subtropics and of changing land use priorities in Europe and North America also make this book of value to those concerned with tree species preservation and survival.
