Book Description
ÿThe large genus Orthomorpha is rediagnosed and is shown to currently com-prise 51 identifiable species ranging from northern Myanmar and Thailand in the Northwest to Lombok Island, Indonesia in the Southeast. Of them, 20 species have been revised and/or abundantly illustrated, based on a res-tudy of mostly type material; further 12 species are described as new: O. atypica sp. n., O. communis sp. n., O. isarankurai sp. n., O. picturata sp. n., O. similanensis sp. n., O. suberecta sp. n., O. tuberculifera sp. n., O. subtuberculifera sp. n. and O. latiterga sp. n., all from Thailand, as well as O. elevata sp. n., O. spiniformis sp. n. and O. subelevata sp. n., from northern Malaysia. The type-species O. beaumontii (Le Guillou, 1841) is redescribed in due detail from male material as well, actually being a senior subjective synonym of O. spinala (Attems, 1932), syn. n. Two additional new synonymies are proposed: O. rotundicollis (Attems, 1937) = O. tuberculata (Attems, 1937), syn. n., and O. butteli Carl, 1922 = O. consocius Chamberlin, 1945, syn. n., the valid names to the left. All species have been keyed and all new and some especially widespread species have been mapped. Further six species, including two revised from type material, are still to be considered dubious, mostly because their paraterga appear to be too narrow to represent Orthomorpha species. A new genus, Orthomorphoides gen. n., diagnosed versus Orthomorpha through only moderately well developed paraterga, coupled with a poorly bi- or trifid gonopod tip, with at least some of its apical prongs being short spines, is erected for two species: O. setosus (Attems, 1937), the type-species, which is also revised from type material, and O. exaratus (Attems, 1953), both comb. n. ex Orthomorpha.

Book Description
"The Myriapoda” is the first comprehensive monograph ever on all aspects of myriapod biology, including external and internal morphology, physiology, reproduction, development, distribution, ecology, phylogeny and taxonomy. It is thus of major interest for all zoologists and soil biologists.

Book Description
Myriapods are the only major zoological group for which a modern encyclopedic treatment has never been produced. In particular, this was the single major gap in the largest zoological treatise of the XIX century (Grassé’s Traité de Zoologie), whose publication has recently been stopped. The two volumes of “The Myriapoda” fill that gap with an updated treatment in the English language. Volume II deals with the Diplopoda or millipedes. As in the previous volume, the treatment is articulated in chapters dealing with external and internal morphology, physiology, reproduction, development, distribution, ecology, phylogeny and taxonomy. All currently recognized suprageneric taxa and a very large selection of the genera are considered. All groups and features are extensively illustrated by line drawings and micrographs and living specimens of representative species of the main groups are presented in color photographs.

Book Description
This volume surveys advances in the study of adaptive radiation showing how molecular characters can be used to analyze the origin and pattern of diversification within a lineage in a non-circular fashion.

Book Description
This is the first comprehensive synopsis of the biodiversity of Diptera, with chapters on all regional faunas, Diptera as ecological indicators, statistical techniques for estimating species diversity based on the known fauna, molecular tools and trends in digital publication.

Book Description
"The author begins by defining phenotypic plasticity and detailing its history, including important experiments and methods of statistical and graphical analysis. He then provides extended examples and discussion of the molecular basis of plasticity, the plasticity of development, the ecology of plastic responses, and the role of costs and constraints in the evolution of plasticity. A brief epilogue looks at how plasticity studies shed light on the nature/nurture debate in the popular media.".
