Book Description
The Micropholcommatidae are a family of tiny, distinctive araneoid spiders, known from southern-temperate habitats throughout Australasia and Chile. The greatest abundance of individuals and the largest diversity of taxa occur in the cool-temperate rainforests of south-eastern Australia and New Zealand, where micropholcommatid spiders can be very common within moss and leaf litter microhabitats. Although poorly studied biologically and largely neglected taxonomically, the Micropholcommatidae are a diverse lineage, with a significantÿ The monograph in this volume presents a complete generic-level revision of the spider family Micropholcommatidae. The phylogenetic position and internal phylogeny of the family are tested with two separate morphological cladistic analyses, the results of which inform a comprehensive generic-level classification. In total, 26 new species, 12 new genera, one new tribe and two new subfamilies are described, taking the total documented micropholcommatid fauna to 58 species. The distribution and Gondwanan biogeography of the family are also discussed, and natural history information is provided where known. Most importantly, the results of this paper present a taxonomic framework and a phylogenetic foundation for all future research on the Micropholcommatidae; a template by which new species can be described and existing species can be identified, and a valuable dataset for exploring phylogenetic hypotheses.

Book Description
Compared to insects, fossil spiders have received only scant attention in the literature. Previously, the only works available were numerous scientific papers, many published in foreign languages. Most of these are basic descriptive taxonomic works, with very few considering broader biological concepts. Despite a significant increase in the discovery and description of fossil spiders within the last quarter Century this void remained unfilled. Thus, this short monograph aims to achieve several objectives. Firstly, to provide general and up to date background information on the overall importance and diversity of fossils spiders, including an indication of those groups for which the taxonomy is spurious and in need of reassessment. Secondly, to discuss the techniques available for working with fossil spiders and some of the problems encountered by palaeoarachnologists, including bias and limitations of the spider fossil record. Thirdly, the overall evolutionary history of spiders is summarized in the form of an evolutionary tree, which is subsequently used to address key issues of broad interest, such as origins, diversifications and extinctions, including the effects of mass extinctions and predator-prey co-radiations. Finally, the contribution that fossil data can make to understanding the past and present biogeography of the order is considered. This book should be of interest to both amateur and professional arachnologists and palaeontologists and will also serve as a general palaeontological reference work for neonologists studying extant spiders.

Book Description
This volume merges all geographical and paleogeographical data on all groups of the arachnofauna. The book features topics such as the ecological factors, climate and other barriers that influence the distribution of arachnida. It also elaborates on the characteristics of the distribution such as arachnida at high altitude (e.g. Himalaya), in caves, in polar regions and highlights differences between the arachnofauna of e.g. Mediterranean regions vs Central Europe, West African vs Indomalayan and more. Furthermore, amongst other topics the volume also includes chapters on the systems of arachnida, fossil orders, dispersal and dispersion, endemics and relicts, regional arachnogeography, cave and high altitude arachnida.

Book Description
Recently another book on insect physiology was published. It was restricted to a few focal points as are many of these new insect physiology books, but there was considerable depth in its specialized point of view. We were dis cussing the structure of this book and of insect physiology books, in general, when Prof. Remmert asked me " . . . and what about books on spider physio logy?" Silence. Then I started to explain "oh yes, there is a congress pro ceedings volume on this topic and there is a group with excellent publica tions on another topic . . . ", but I felt that this answer was weak. One can no longer buy the proceedings volume in a bookshop and to read a series of publications on a given topic one must search in a library for a dozen journals. Why is there not a single book on spider physiology comparable with the many books on insect physiology? Are spiders a scientific ivory tower, far from public interest and commercial importance? I do not think so, although spiders are one of the many "forgotten" animal groups which always grew in the shadow of the insects. There are research groups working on spider physiology, there are fascinating phenomena in this animal group and there are plenty of exciting results. Spiders may have been always underresearch ed, but research is progressing. In the last few years, new books have been published, e. g.

Book Description
Systematics underpins all of biology. Cladistics is a method of systematic classification that aims to reconstruct genealogies based on common ancestry, thus revealing the phylogenetic relationships between taxa. Its applications vary from linguistic analysis to the study of conservation and biodiversity, and it has become a method of choice for comparative studies in all fields of biology. For all students interested in the systematic relationships among organisms, this book provides an integrated, state-of-the-art account of the techniques and methods of modern cladistics, and how to put them into practice.

Book Description
In The Greenland Entomofauna an international team of 64 taxonomic specialists provide for the first time a richly illustrated guide to the identification of the ≈1200 species of Hexapods/Insects, Arachnids and Myriapods so far known to occur in the country. While the composition, origin and adaptations of the Greenland fauna has always been a challenge to biogeographers and ecologists/ecophysiologists, the provision of a tool for detailed identification of its constituent species is now particularly timely, since global climate change will expectedly have a particularly noticeable impact on biota at high latitudes. This obviously renders the feasibility of monitoring distributional range shifts of the principal components of this biota a matter of some urgency.
