DOWNLOAD EBOOKThe present catalog provides a compilation of all supra- and (infra-) specific taxa of extant and fossil Valvatidae (Ectobranchia), a group of freshwater operculate snails (Gastropoda, Heterobranchia). Taxa initially described in this family and bsequently classified in other families (in particular Hydrobiidae and Planorbidae, but among others also larval shells of trichopteran insects) as well as names due to errors or misspellings are likewise included. For each taxon the full original reference and the ype locality (and type horizon in fossils) is provided. Remarks on nomenclatorical problems and possible solutions are added if necessary. As a novelty the extensive reference list is as far as possible directly linked to the internet source (digital view or pdf-download) of the respective papers to facilitate future taxonomic research.

DOWNLOAD EBOOKInvertebrate animals make up the greater part of the world's biological diversity and are present in all habitats, where they perform essential ecological functions. Their survival is fundamental to the maintenance of life as we know it. Large numbers of invertebrate species are under severe threat of extinction in Europe, or are already extinct due to the extreme transformations that European habitats have suffered due to human activities. The European Strategy for the conservation of invertebrates, adopted by the Council of Europe (Bern Convention) in 2006, addresses the loss of invertebrate biodiversity and promotes their conservation and the services they provide in terrestrial and non-marine aquatic environments. The Strategy offers appropriate guidance to European governments, other decision-makers, land managers, scientists and teachers that have potential influence on invertebrate conservation.

DOWNLOAD EBOOKFunctional ecology is the branch of ecology that focuses on various functions that species play in the community or ecosystem in which they occur. This accessible guide offers the main concepts and tools in trait-based ecology, and their tricks, covering different trophic levels and organism types. It is designed for students, researchers and practitioners who wish to get a handy synthesis of existing concepts, tools and trends in trait-based ecology, and wish to apply it to their own field of interest. Where relevant, exercises specifically designed to be run in R are included, along with accompanying on-line resources including solutions for exercises and R functions, and updates reflecting current developments in this fast-changing field. Based on more than a decade of teaching experience, the authors developed and improved the way theoretical aspects and analytical tools of trait-based ecology are introduced and explained to readers.

DOWNLOAD EBOOKWritten for academic researchers and graduate students in entomology, this is the first comprehensive analysis of Sciomyzid flies. Sciomyzid flies are important as prime candidates for the biological control of snails and slugs that help transmit diseases such as schistosomiasis or are important agricultural pests. They also serve as a paradigm for the study of the evolution of feeding behavior in predatory insects. Starting with analyses of malacophagy in general and then in Diptera specifically, all important aspects of the Sciomyzidae are discussed, including behavior, ecology, life cycles, morphology, and identification. New behavioral and morphological classifications and hypotheses are proposed on the basis of unpublished information and a complete analysis of the extensive literature. Also included are keys to adults, larvae and puparia and a checklist of world species, with information on geographical range and the location of type specimens. The accompanying DVD includes Clifford O. Berg's classic film on the biology of Sciomyzidae and biological control of snails.

DOWNLOAD EBOOKConstructional morphology explains features of organisms from a constructional and functional point of view. By means of physical analysis it explains the operational aspects of organic structures - how they can perform the activities organisms are expected to fulfil in order to survive in their environment. Constructional morphology also explains options and constraints during the evolution determined by internal constructional needs, ontogenetic demands, inherited organizational preconditions and environmental clues.

DOWNLOAD EBOOKUsing original Victorian prints, by collectable artist George Sowerby, marine biologist and author Paul Chambers has produced the first comprehensive guide to shells for over a century. The original prints are intricately detailed (much better than photographs which lack the exact detail of these drawings) and are a selling point in themselves but will be complemented by informative but accessible text, including families and to show what's edible, dangerous or belongs to mollusc families and in what part of the country they can be discovered. A delightful study by the leading expert and a must for anyone interested in learning more about shells - or who just enjoys beachcombing with the family.
