Book excerpt: Excerpt from Germination, Survival and Early Growth of Conifer Seedlings in Two Habitat Types Seed germination and seedling survival in the field are as important to natural forest regeneration as are the production and dispersal of seeds. Many seeds are produced and dispersed, but most do not germinate or they fail to survive after germination. This severe seed and seedling mortality multiplies the number of seeds required to obtain natural regeneration. It also acts as a selective factor in determining the genetics of future stands. The relation of dispersed seed populations to established seedling populations is not well known for most high elevation forests in the Pacific Northwest. Production and dispersal of conifer seeds in the Abies amabilis forest zone described by Franklin and Dyrness (1973) have been well studied (carkin and others 1978; Franklin and others 1974; Franklin and Smith 1974a, 1974b), but little work has been done on the fate of those seeds. Sullivan (1978) compared forest regenera tion on clearcuts in several habitat types within the Abies amabilis zone and con cluded that regeneration differed significantly among habitat types, but he did not relate his observations and conclusions to the seed supply. Neither did Halverson and Emmingham who were unable to correlate forest regeneration in the Abies amabilis zone with habitat types, but found extremes in environment to be the most probable cause of regeneration failure. Seidel (1979a) surveyed mixed conifer regeneration on many clearcuts along the east side of the Cascade Range and in the Blue Mountains of Oregon. He measured the variation among plant community types and geographic locations, but did not relate established regeneration to amounts of seed or early seedling mortality and did not derive any ratios for seeds to established seedlings. Seidel (1979b) also studied regeneration after shelterwood cutting in a grand fir (abies grandis (dougl. Ex D. Don) Lindl.) Shasta red fir (abies magnifica var. Shastensis Lemm.) stand in central Oregon. The number of sound seeds collected in his seed traps can be compared to the number of seedlings that became established during the 5-year measurement period to derive seed-to-seedling ratios for four slash treatments under three overstory densities. Those ratios varied from about on bulldozed seedbeds under an overstory with basal area of square meters per hectare to about on undisturbed seedbeds under the same overstory.

Book Synopsis Seedling Ecology and Evolution by : Mary Allessio Leck
Download or read book Seedling Ecology and Evolution written by Mary Allessio Leck and published by Cambridge University Press. This book was released on 2008-09-18 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seedlings are highly sensitive to their environment. After seeds, they typically suffer the highest mortality of any life history stage. This book provides a comprehensive exploration of the seedling stage of the plant life cycle. It considers the importance of seedlings in plant communities; environmental factors with special impact on seedlings; the morphological and physiological diversity of seedlings including mycorrhizae; the relationship of the seedling with other life stages; seedling evolution; and seedlings in human altered ecosystems, including deserts, tropical rainforests, and habitat restoration projects. The diversity of seedlings is portrayed by including specialised groups like orchids, bromeliads, and parasitic and carnivorous plants. Discussions of physiology, morphology, evolution and ecology are brought together to focus on how and why seedlings are successful. This important text sets the stage for future research and is valuable to graduate students and researchers in plant ecology, botany, agriculture and conservation.

Download or read book Forest Succession written by D. C. West and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: Succession-nothing in plant, community, or ecosystem ecology has been so elaborated by terminology, so much reviewed, and yet so much the center of controversy. In a general sense, every ecologist uses the concept in teaching and research, but no two ecologists seem to have a unified concept of the details of succession. The word was used by Thoreau to describe, from a naturalist's point of view, the general changes observed during the transition of an old field to a forest. As data accumulated, a lengthy taxonomy of succession developed around early twentieth century ecologists such as Cooper, Clements, and Gleason. Now, nearer the end of the century, and after much discussion concerning the nature of vegetation communities, where do ecologists stand with respect to knowledge of ecological succession? The intent of this book is not to rehash classic philosophies of succession that have emerged through the past several decades of study, but to provide a forum for ecologists to present their current research and present-day interpretation of data. To this end, we brought together a group of scientists currently studying terrestrial plant succession, who represent research experience in a broad spectrum of different ecosystem types. The results of that meeting led to this book, which presents to the reader a unique summary of contemporary research on forest succession.

Book excerpt: "Southern forests provide innumerable benefits. Forest scientists, managers, owners, and users have in common the desire to improve the condition of these forests and the ecosystems they support. A first step is to understand the contributions science has made and continues to make to the care and management of forests. This book represents a celebration of past accomplishments, summarizes the current state of knowledge, and creates a vision for the future of southern forestry research and management. Chapters are organized into seven sections: "Looking Back," "Productivity," "Forest Health," "Water and Soils," "Socioeconomic," "Biodiversity," and "Climate Change." Each section is preceded by a brief introductory chapter. Authors were encouraged to focus on the most important aspects of their topics; citations are included to guide readers to further information."

Available in PDF, EPUB and Kindle. Book excerpt: THE EVOLUTIONARY STRATEGIES THAT SHAPE ECOSYSTEMS In 1837 a young Charles Darwin took his notebook, wrote “I think”, and then sketched a rudimentary, stick-like tree. Each branch of Darwin’s tree of life told a story of survival and adaptation – adaptation of animals and plants not just to the environment but also to life with other living things. However, more than 150 years since Darwin published his singular idea of natural selection, the science of ecology has yet to account for how contrasting evolutionary outcomes affect the ability of organisms to coexist in communities and to regulate ecosystem functioning. In this book Philip Grime and Simon Pierce explain how evidence from across the world is revealing that, beneath the wealth of apparently limitless and bewildering variation in detailed structure and functioning, the essential biology of all organisms is subject to the same set of basic interacting constraints on life-history and physiology. The inescapable resulting predicament during the evolution of every species is that, according to habitat, each must adopt a predictable compromise with regard to how they use the resources at their disposal in order to survive. The compromise involves the investment of resources in either the effort to acquire more resources, the tolerance of factors that reduce metabolic performance, or reproduction. This three-way trade-off is the irreducible core of the universal adaptive strategy theory which Grime and Pierce use to investigate how two environmental filters selecting, respectively, for convergence and divergence in organism function determine the identity of organisms in communities, and ultimately how different evolutionary strategies affect the functioning of ecosystems. This book refl ects an historic phase in which evolutionary processes are finally moving centre stage in the effort to unify ecological theory, and animal, plant and microbial ecology have begun to find a common theoretical framework.
