DOWNLOAD EBOOKThis book spells out the theoretical structure, methodology and philosophy of the science of autecology. The autecological approach focuses on the interactions of individual organisms (and their species-specific adaptations) with the spatio-temporal dynamics of their environment as a basis for interpreting patterns of diversity and abundance in nat

DOWNLOAD EBOOKThis complete introduction to a growing field describes the methods available for analysis of the biological, chemical and physical data collected for autecological studies. It describes and analyzes a range of techniques, from improved in situ techniques to genetic engineering procedures and computer analysis, and discusses potential research in multi-species associations and soil, marine and freshwater habitats.

DOWNLOAD EBOOKThis book is intended as a resource for students and researchers interested in developmental biology and physiology and specifically addresses the larval stages of fish. Fish larvae (and fish embryos) are not small juveniles or adults. Rather they are transitionary organisms that bridge the critical gap between the singlecelled egg and sexually immature juvenile. Fish larvae represent the stage of the life cycle that is used for differentiation, feeding and distribution. The book aims at providing a single-volume treatise that explains how fish larvae develop and differentiate, how they regulate salt, water and acid-base balance, how they transport and exchange gases, acquire and utilise energy, how they sense their environment, and move in their aquatic medium, how they control and defend themselves, and finally how they grow up.

DOWNLOAD EBOOKIt is clear that nature is undergoing rapid changes as a result of human activities such as industry, agriculture, travel, fisheries and urbanisation. What effects do these activities have? Are they disturbing equilibria in ecological populations and communities, thus upsetting the balance of nature, or are they enhancing naturally occurring disequilibria, perhaps with even worse consequences? It is often argued that large-scale fluctuations in climate and sea-levels have occurred over and over again in the geological past, long before human activities could possibly have had any impact, and that human effects are very small compared to those that occur naturally. Should we conclude that human activity cannot significantly affect the environment, or are these naturally occurring fluctuations actually being dangerously enhanced by humans? This book examines these questions, first by providing evidence for equilibrium and non-equilibrium conditions in relatively undisturbed ecosystems, and second by examining human-induced effects.

DOWNLOAD EBOOKThis publication summarizes the autecological characteristics of 35 vegetation species and provides information on how they respond to various silvicultural treatments now in use on forest lands. Information used in this report was gathered in an extensive search of ecological, silvicultural, and botanical literature, most of which originates in western Canada or western US. Information is given on description, distribution and abundance, habitat, growth and development, reproduction, pests, effects on crop trees, response to disturbance or management, and wildlife and range of each species, listed alphabetically by scientific name.

DOWNLOAD EBOOKThis manual contains information on seven commercially important tree species and on 44 plant species that may compete with these crop tree species in northeastern Ontario. The introduction provides background information for the species comparison tables and species summaries that follow, and explains the format of the manual. The tables give information on each species' autecology in the context of the Forest Ecosystem Classification (FEC) system for northeastern Ontario. In addition, each potential competitor is evaluated with respect to their competitive effects and mechanisms, their response to disturbance and silvicultural treatments, and their potential value for wildlife. The crop tree species are evaluated with respect to their response to competition and their ability to respond to release. Line diagrams are included to aid in field recognition. The appendix contains a glossary and a key to FEC names and descriptions.
