Annelida, mainly consisting of marine Polychaeta and in faunal and partly parasitic Clitellata, is one the most significant metazoan taxa. Its more than 20.000 described species invade nearly all habitats and play a central role in marine benthic systems as well as in terrestrial soil communities. Annelids include all soft-bodied segmented worm-like organisms and have been recognized as a separate "phylum" for almost 200 years.

Recently, evidence has been accumulated which shows that some of the groups formerly regarded as independent "phyla" such as Pogonophora (now recognized as...

Numerous improvements in our understanding of the mechanisms that underlie neuropathic pain states have come from the development of animal models, most of which involve partial peripheral nerve injury. The animal models have shown that nerve injury initiates a cascade of events resulting in altered neurochemistry and molecular biology of the peripheral neurons, the dorsal root ganglion cell, and changes in neurotransmitter and receptor expression in the dorsal horn of the spinal cord. Moreover, nerve injury produces anatomical changes with functional consequences.

In this book the author explores the shifting philosophical boundaries of modern medical knowledge and practice occasioned by the crisis of quality-of-care, especially in terms of the various humanistic adjustments to the biomedical model. To that end he examines the metaphysical, epistemological, and ethical boundaries of these medical models. He begins with their metaphysics, analyzing the metaphysical positions and presuppositions and ontological commitments upon which medical knowledge and practice is founded. Next, he considers the epistemological issues that face these medical...

There is still a widespread belief that microscopic organisms, such as bacteria, fungi, protists, and small multicellulars, have a cosmopolitan distribution due to a presumed easy dispersal by wind and water. However, the contributions collected in this book - ranging from protists to rotifers and mosses - show that microorganisms have community structures and biogeographies similar to those found in animals and vascular plants, although the ranges of many can be wider and local endemism is rarer. Accordingly, the cosmopolitan distribution model of Finlay and Fenchel is to be replaced by...

In the field of molecular evolution, inferences about past evolutionary events are made using molecular data from currently living species. With the availability of genomic data from multiple related species, molecular evolution has become one of the most active and fastest growing fields of study in genomics and bioinformatics.

Most studies in molecular evolution rely heavily on statistical procedures based on stochastic process modelling and advanced computational methods including high-dimensional numerical optimization and Markov Chain Monte Carlo. This book provides an overview...

Electron tomography has become a standard technique with applications in cell biology, structural biology, and materials science. This definitive work provides a comprehensive treatment of the mathematical background and working methods of three-dimensional reconstruction from tilt series, with special emphasis on the problems presented by limitations of data collection in the transmission electron microscope. In addition to chapters that are applicable to 3D reconstruction in all fields of science, such as radiological imaging in medicine and electron tomography in materials science,...
