Palaeobatrachidae are an extinct family of frogs whose earliest members are recorded from the Middle Eocene (Geiseltal, Messel, Germany), almost 50 million years ago, although there are indications that they appeared as early as before the Cretaceous mass extinction event and survived almost to our times. Their last survivors are recorded from the Middle Pleistocene, less than 0.5 million years ago, such that they were contemporaries of Neanderthal man. Their last fossil evidence is from the regions that were adjacent to the Pleistocene continental glacier. Like today's pipid frogs (e.g. Xenopus), they were obligate water dwellers, not able to make long excursions onto dry land. Without exaggerating, they literally died out frozen in their ponds. Permanent life in water has a uniforming effect. This is why they all looked similar to one another, which is a source of difficulty for taxonomists. On the other hand, one cannot overlook features they have in common with pipids, restricted to the southern hemisphere. Palaeobatrachus and Xenopus are undoubtedly related, but when and why ancestors of Palaeobatrachus immigrated to the western part of northern Eurasia but not to its eastern part and not to North America remains a puzzling question. Thus, being acquainted with Palaeobatrachus means to be invited on an excursion not only into comparative anatomy, but also into paleogeography and many other fields of palaeontology. Last but not least, Palaeobatrachus was the first fossil frog scientifically described, as early as in 1831. Since that time, many excavation sites from which original material came have ceased to exist; thus there is no possibility that further material will be recovered. What is now deposited in scientific collections is the unique and limited source of data for future comparative studies. This is one of the main reasons why this rich illustrated review was published.

This field guide covers northern to central Tanzania, southern Kenya and parts of central Kenya. Most species are illustrated by live specimens; generally, adult males and females are depicted, along with selected nymphal stages. For species-rich genera, morphological details are provided, together with keys to genera and species as well as distribution maps for most taxa. The enclosed DVD features the songs of 185 species. More than 270 bushcricket species are treated, including raspy crickets (7 genera) and wetas (2 genera). The majority of the species shown are from the family Tettigoniidae, particularly from the subfamily Conocephalinae (including the tribes Agraeciini, Conocephalini and Copiphorini); in addition, the subfamilies Hetrodinae, Hexacentrinae, Meconematinae, Saginae, and Mecopodinae are represented as well. The subfamily Phaneropterinae is the most diverse in the area, with six genera in the tribe Acrometopini, plus representatives of the tribes Amblycoryphini, Catoptropterigini, Ducetiini, Holochlorini, Odonturini, Otiaphysini, Pardalotini, Phaneropterini, Terpnistrini and Tylopsidini. Genera of ungrouped Phaneropterinae in the area include Ectomoptera, Eulioptera, Euryastes, Lunidia, Materuana, Meruterrana, Oxyecous, Pseudopreussia, Sentia and Tropidonotacris. The subfamily Pseudophyllinae is also present with six genera (Acauloplax, Cymatomera, Cymatomerella, Pseudotomias, Stenampyx and Zabalius).

Messel - An Ancient Greenhouse Ecosystem is an exquisitely illustrated book by 28 internationally renowned specialists who present a synopsis of the current state of understanding of the climate and structure of the Eocene Messel ecosystem. The information is derived from studying the rocks, animal and plant fossils of the Messel pit. The Messel Pit represents an ancient maar lake situated in the archipelago that Europe was in the Eocene, close to present-day Frankfurt, Germany. This title is also available in a German language version. The exceptional state of preservation of Messel fossils has enabled researchers, in many cases for the first time, to identify minute functional details of the plants and animals of the Messel ecosystem about 48 Million years ago: plants, insects, birds, mammals (horses!), reptiles, amphibians and fishes. Introductory chapters treat Messel, its formation as a maar lake, the conditions of burial and preservation of the fossils, and history of work since discovery of the first fossil there in 1876. The Messel flora and individual fossils groups are discussed in detail in seven following chapters, discussing both paleontological and evolutionary details obtained from the Messel fossils and by comparison with other fossil locations. A final chapter summarizes all previous research and presents a synopsis of ecosystem conditions (climatic, environmental, biota, producers and consumers, occupation of ecospaces, niches) of the terrestrial and aquatic ecosystems at Messel, derived from studies of the Messel samples. This hitherto most comprehensive treatment of the fossil Messel ecosystem will make this book the standard reference work on Messel to scientists, while the lush illustrations of flora and fauna will captivate everyone from fossil enthusiasts to interested laypersons.

This publication presents the first summary of our knowledge of benthic dinoflagellate species. Dinoflagellates are important primary producers and symbionts, but, at the same time, also consumers and parasites. Species compositions of benthic habitats are quite distinct from those of planktonic habitats. Less than 10% of the approximately 2000 described extant dinoflagellate species appear to be benthic. They occur in different types of habitats (chapter II) and their morphology, their behavior, and some of their life cycles (chapter VI) seem to be well adapted to the benthic lifestyle. Information on their geographic distribution is still very limited and is compiled herein (chapter V). The study of harmful benthic dinoflagellates started in the late 1970s when it was suspected that a benthic species, later named Gambierdiscus toxicus, was responsible for ciguatera fish poisoning, a type of human poisoning linked to the consumption of certain species of tropical reef fish. As the number of ciguatera fish poisoning incidents increases, and the distribution of toxin producing benthic taxa seems to be expanding, detailed understanding of the species diversity and the ability to accurately identify them is becoming increasingly important (chapter VII). Dinoflagellate classification is currently undergoing changes and far from being settled, as new species and genera are discovered and systematic entities are rearranged. Many benthic dinoflagellate genera have unusual morphologies and appear to be only remotely related to known planktonic taxa, so that molecular phylogenetic analyses frequently show little statistical support for any relationship (chapter IV). Benthic species display unique thecal plate arrangements compared to planktonic species, e.g. Adenoides, Amphidiniella, Cabra, Planodinium, Sabulodinium, Rhinodinium (chapter III). Therefore, no classification on higher rank levels (e.g. family, order) was used throughout this book. Genera (and species within a genus) are presented in alphabetical order. The book presents the first comprehensive identification help for benthic dinoflagellates. At the same time it aims to lend support in order to improve monitoring efforts worldwide. About 190 species in 45 genera are presented in detail, illustrated with more than 200 color images, approximately 150 scanning electron micrographs, and more than 250 drawings.

This new book is a comprehensive description of human physical growth and development (Auxology) with contributions by 56 internationally reputed experts. The entire spectrum of basic and advanced information on growth tracking, growth prediction, short-term-, catch-up- and rapid growth, nutritional and social factors influencing human growth, and issues related to preventive health care, growth in ethnic minorities and migrants, and growth in developing countries is presented. The text is generously illustrated by 270 colour figures and 89 comprehensive tables. The text also introduces new mathematical approaches to growth modelling and provides practical information on how to use and interpret growth charts. Current national references for height, weight, body mass index (BMI) and head circumference for various countries (US, ARG, BRA, CAN, IND, BEL, GER, IT, NL, PL, SW, SWI, TUR, UK, WHO) are provided, as are growth references for twins, preterm infants and syndrome specific growth charts for clinical purposes. The book is of greatest interest to all pediatricians, to medical students and students of human biology, health workers, nutritionists, medical staff and professionals interested in child and adolescent growth and development.
