The graptolites constitute one of the geologically most useful taxonomic groups of fossils for dating rock successions, understanding paleobiogeography and reconstructing plate tectonic configurations in the Lower Palaeozoic. Graptolites were largely planktic, marine organisms, and as one of the first groups that explored the expanses of the world’s oceans are vital for understanding Palaeozoic ecology. They are the best and often the only fossil group for dating Lower Palaeozoic rock successions precisely. Thousands of taxa have been described from all over the planet and are used for a wide variety of geological and palaeontological (biological) research topics. The recent recognition of the modern pterobranch Rhabdopleura as a living benthic graptolite enables a much better understanding and interpretation of the fossil Graptolithina. In the decades since the latest edition of the Graptolite Treatise, the enormous increase of knowledge on this group of organisms has never been synthesised in a compelling and coherent way, and information is scattered in scientific publications and difficult to sort through. This volume provides an up-to-date insight into research on graptolites. Such research has advanced considerably with the use of new methods of investigation and documentation. SEM investigation and research on ultrastructure of the tubaria has made it possible to compare extant and extinct taxa in much more detail. Cladistic interpretation of graptolite taxonomy and evolution has advanced the understanding of this group of organisms considerably in the last two decades, and has highlighted their importance in our understanding of evolutionary processes. This book will show graptolites, including their modern, living relatives, in a quite new and fascinating light, and will demonstrate the impact that the group has had on the evolution of the modern marine ecosystem. This book is aimed not only at earth scientists but also at biologists, ecologists and oceanographers. It is a readable and comprehensible volume for students at the MSc level, while remaining accessible to undergraduates and non-specialists seeking up-to-date information about this fascinating topic in palaeobiology.

Winner of The Royal Society of Literature Jerwood Award for Non-Fiction in 2011 and the Authors' Foundation Roger Deakin Award in 2011A stunning debut in the tradition of Robert Macfarlane and Helen MacdonaldOf all the birds of the British Isles, the raptor reigns supreme, sparking the imagination like no other. In this magnificent hymn to these beautiful animals, James Macdonald Lockhart explores all fifteen breeding birds of prey on these shores – from the hen harrier swimming over the land in the dregs of a May gale on Orkney, to the ghostly sparrowhawk displaying in the fields around his home in Warwickshire. This is a book that will change how we think of our own skies.

Rok 2017. W Ukladzie Slonecznym po raz pierwszy pojawia sie okret Skunow. Ludzkosc nadaje mu nazwe Oumuamua. Dwa lata pozniej obiekt znika w tajemniczej anomalii, znajdujacej sie pomiedzy Marsem i Jowiszem. Wkrotce przybywaja nastepne okrety obcych. Wyslane ich tropem ziemskie sondy badawcze odkrywaja w tym rejonie przejscie, prowadzace do odleglego o dziesiec lat swietlnym ukladu gwiezdnego Epsilon Eridani, zamieszkalego przez rase Skun. Rok 2045. Do ukladu Epsilon Eridani wlatuja pierwsze ziemskie okrety kolonizacyjne. Rok 2205. Dominium Skun jest juz tylko wspomnieniem. Zdziesiatkowani obcy ukrywaja sie w pasie planetoid na obrzezach ukladu, skad przypuszczaja atak na kolonistow. W kierunku jedynej w ukladzie planety i jej ksiezyca wyrusza gigantycznych rozmiarow okret wojenny Skunow. Strzegaca planety Flota ludzi jest rozproszona, w ukladzie znajduje sie jedynie niewielki zespol uderzeniowy, zlozony z krazownika i kilku okretow eskorty. Czy pojedynczy okret potrafi powstrzymac przewazajace sily wroga? Czy ludzkosc bedzie w stanie uchronic nowa domene przed zaglada? Jak wiele ludzie sa w stanie poswiecic, by tego dokonac?
