This selection of reviews gives an up-to-date picture of memory research. Great progress has been made in identifying the memory trace at the molecular and cellular level and individual reviews address the major mechanisms by which changes in synaptic strength can persist. Exciting research at the systems level is also reviewed including the growing importance of changes in inhibitory interneurons and how they play a role in memory formation. Finally, reviews present cognitive and neurobiological models of human memory that explain, characterize and organize the act of memory within a coherent framework. - Provides an unique overview that covers all perspectives and methodological approaches to memory - Broad coverage of memory research from molecular to human studies in one source - Up-to-date reviews give the latest important ideas on memory formation
The First Edition of Ecology and Classification of North American Freshwater Invertebrates has been immensely popular with students and researchers interested in freshwater biology and ecology, limnology, environmental science, invertebrate zoology, and related fields. The First Edition has been widely used as a textbook and this Second Edition should continue to serve students in advanced classes. The Second Edition features expanded and updated chapters, especially with respect to the cited references and the classification of North American freshwater invertebrates. New chapters or substantially revised chapters include those on freshwater ecosystems, snails, aquatic spiders, aquatic inse...
This work covers the geographical distribution of Crustaceans with hypotheses on how the distribution took place, based on fossil and recent records.
This study represents the first scholarly attempt to consider the difficult allocation problems associated with management of natural resources and proposed changes in the natural environment. Originally published in 1973
This book gives a comparative treatment of topics accross lake, reservoir, and rive ecosystems. These analysis do indeed indicate differences among the properties of lakes, land-water interface regions, reservoirs, and rivers. Importantly, these analysis also indicate marked commonality in function.
This text, written by a leading researcher in the field, describes the origin and formation of lakes in order to give context to the question of how lacustrine deposits form. It explains the process of sedimentation in lakes and the chemistry of those deposits and describes how the age of lake deposits are determined. Additionally, this book shows how different groups of fossils are used in interpreting the paleontological record of lakes. In order to illustrate the more synthetic approaches to interpreting the history of lakes, the author also discusses such special topics as lake-level history, lake evolution, and the impact of environmental change on lakes.
To trace the effects of cultural eutrophication, one meter sediment cores were used to determine the history of calcareous and noncalcareous Wisconsin lakes. Cores were analyzed for carbon, phosphorus, calcium, magnesium, potassium, aluminum, iron, and manganese. Determinations of organic nitrogen, exchangeable ammonium and acid soluble phosphorus were made on selected sedimentary profiles. Recent sedimentation rates and identification of pre- and postcultural sediments were determined by ragweed pollen. Enrichment of phosphorus in postcultural Lake Mendota, Wisconsin, sediments are the effect of increased phosphorus supply from domestic sewage. Chemical stratigraphy of concentration-depth diagrams permit a qualitative evaluation of cultural activities. Potentialities and limitations of using recent lake sediments to evaluate eutrophication are discussed.
The Third International Symposium on Cladocera, papers from which make up this volume, covered recent findings on the behaviour, life history, population genetics, reproduction, chemical communication, predator-prey interactions, epibionts, taxonomy, phylogeny, palaeolimnology and biogeography of this animal group. The Cladocera occupy an intermediate position in lake ecosystems, both as plankton and benthic organisms. Their often high abundance and their function, as transfer organisms from algae and dead organic matter to macro-invertebrates and fish, make them one of the most important organisms to affect the biological processes in freshwater ecosystems. The Cladocera living among the plankton often have recognizable distribution patterns and migrations; their size and brief life cycles make them popular in laboratory experiments; their cyclic parthenogenesis makes them suitable for many aspects of population genetics; and they are present as microfossils in lake sediments. All these features confer a unique status on the Cladocera as model organisms in many aspects of modern systematics and ecology.
