This book focuses on recent advances in our understanding of the signal transduction pathway of ethylene, its interaction with other hormones and its roles in biological processes.
The book addresses this critical need by providing a straightforward and easy to read primer to key elements of at-risk butterfly conservation programs including captive husbandry, organism reintroduction, habitat restoration, population monitoring, recovery planning and cooperative programs.
True bugs (Heteroptera) are a diverse and complex group of plant-feeding and predatory insects important to food production, human health, the global economy and the environment.
Stem cells have the ability to differentiate into all types of cells within the body, thus have great therapeutic potential for regenerative medicine to treat complicated disorders, like Parkinson's disease and spinal cord injury.
This volume contains the Proceedings of the 4th International Conference on Ticks and Tick-borne Pathogens (TTP-4), held in Banff, Alberta, Canada, from 21 to 26 July 2002.
The book is a new compendium in which leading termite scientists review the advances of the last 30 years in our understanding of phylogeny, fossil records, relationships with cockroaches, social evolution, nesting, behaviour, mutualisms with archaea, protists, bacteria and fungi, nutrition, energy metabolism,population and community ecology, soil conditioning, greenhouse gas production and pest status.
Ecology and Morphology of Copepods is organized under the following general topics: Behavior, Feeding, Genetics, Horizontal Variations, Morphology, Phylogeny, Reproduction, Seasonal Changes, Vertical Distribution, plus two special sessions on copepods of the genus Acartia and cyclopid/mosquito interactions.
Ostracoda (Crustacea) are potentially excellent model organisms for evolutionary studies, because they combine an extensive fossil record with a wide recent distribution and therefore allow studies on both patterns and processes leading to extant diversity.
This book is a collection of papers given by invited speakers at a Symposium on 'Feedback and Motor Control', held at the University of Glasgow from July 10th to 13th 1984, which was attended by over 200 scientists from 20 countries.
1 Modern biologists describe protozoa as microscopic eukaryotic organ- isms with a capacity for establishing themselves in almost every con- ceivable habitat provided it contains moisture in some form.
Recent studies on diverse aspects of the biology of clitellate works (oligochaetes and leeches) are found in the Proceedings of the most recent International Symposium on Aquatic Oligochaete Biology - from development to population dynamics and from ultrastructure to evolution.
The arthropods contain more species than any other animal group, but the evolutionary pathways which led to their current diversity are still an issue of controversy.
This book contains 36 of the papers presented at the meetings covering the many aspects of oligochaete biology from ecological through evolutionary studies, divided into the following sections: Systematics and Evolution Taxonomy and Geographic Distribution Distribution, Abundance and Habitat Types Ultrastructure Pollution Studies Population Dynamics The volume highlights the single largest contribution of Soviet oligochaete biology presented in English since 1980.
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.
Metastatic dissemination of cancer is a main cause of cancer related deaths, therefore biological mechanisms implicated in metastatic process presents an essential object of cancer research.
With the discovery of stem cells capable of multiplying indefinitely in culture and differentiating into many other cell types in appropriate conditions, new hopes were born in repair and replacement of damaged cells and tissues.
Three major aspects that distinguish this book are that (1) it contains the most detailed analysis of the sexual reproduction (oogenesis, fertilization and embryonic incubation) in a particular phylum of the aquatic invertebrates (Bryozoa) ever made; this analysis is based on an exhaustive review of the literature on that topic published over the last 260 years, as well as extensive original histological, anatomical and morphological data obtained during studies of both extant and extinct species; (2) this broad analysis has made it possible to reconstruct the major patterns, stages and trends in the evolution of sexual reproduction in various bryozoan clades, showing numerous examples of parallelisms during transitions from broadcasting to embryonic incubation, from planktotrophic to non-feeding larvae and from lecithotrophy to placentation; corresponding shifts in oogenesis, fertilization and embryonic development are discussed in detail; and (3) the key evolutionary novelties acquired by Bryozoa are compared with similar innovations that have evolved in other groups of marine invertebrates, showing the general trends in the evolution of their sexual reproduction.
This volume, The Science of Algal Fuels (volume 25 of COLE), contains 26 chapters dealing with biofuels contributed by experts from numerous countries and covers several aspects of algal products, one being "e;oilgae from algae,"e; mainly oils and fuels for engines.
This book provides an introductory overview to the social debate over enhancement technologies with an overview of the transhumanists' call to bypass human nature and conservationists' argument in defense of it.
NMR spectroscopy has undergone a revolution in recent years with the advent of several new methods overcoming the problems of sensitivity and resolution.
Angiogenesis and lymphangiogenesis have become attractive targets for drug therapy because of their key roles in a broad spectrum of pathological disease states ranging from macular degeneration to tumor growth and metastasis.
As a result of the European Commission's concern for the status of continental waters, and as a clear reflection of the notion of water as heritage to be conserved, in the year 2000 the Water Framework Directive (2000/60/CE) was enacted, its goal being to establish a framework to protect water and the different aquatic ecosystems by requiring the Member States to achieve a good ecological status in all their waters by 2015.
The book introduces basic entomology, emphasising perspectives on insect diversity important in conservation assessment and setting priorities for management, as a foundation for managers and others without entomological training or background.
Fisheries genetics researchers will find invaluable the thirty-eight peer-reviewed contributions in this book, presented at the 20th Lowell Wakefield Fisheries Symposium "e;Genetics of Subpolar Fish and Invertebrates,"e; held in May 2002 in Juneau, Alaska.
Over the last few years, bacterial adhesion has become a more and more important and active scientific area, but the field lacks communication and scientific exchange between medical and microbiology researchers who work with the relevant biological systems, and biochemists, structural biologists and physicists, who know and understand the physical methods best suited to investigate the phenomenon at the molecular level.
