Bees are a fascinating and indispensable group of insects, but many species are in decline, and efforts to help determine distributions and changes in abundance have to date been compromised by a serious lack of identification resources. This eagerly anticipated new addition to the highly acclaimed British Wildlife Field Guides series will unravel the complexities of identification, and is designed to cater for people new to the bee world as well as to more experienced recorders who wish to identify every species accurately. It provides the latest information on the identification, ecology, status and distribution of all 275 species of bee in Britain, Ireland and the Channel Islands.- Written by Steven Falk, professional naturalist and conservationist with over forty years' experience of working with bees- Illustrated with over 1,000 colour and black & white artworks by Richard Lewington, one of Europe's leading insect artists- Stunning photographs of living insects as seen in the wild- 234 up-to-date distribution maps- Comprehensive introduction to bee classification, ecology, field techniques and recording, a full glossary, and information on how to separate the sexes and distinguish bees from other insects- Introductions to families and genera, describing key characters and life histories- Detailed species descriptions covering field and microscopic characters, similar species, variants, flight season, habitat, flowers visited, nesting habits, status & distribution, and parasites & associates- A series of innovative illustrated keys to genera and species, designed to guide the user step by step through the identification process

Achtergrondinformatie over 96 zeer diverse thema's, van klimaat tot menselijke geschiedenis, om het poollandschap te begrijpen. In de Arctis leven al vele duizenden jaren mensen, dieren, planten en microben. Ze hebben zich aangepast aan de extreme omstandigheden, het is hun thuis. Maar hun thuis heeft een dynamisch en kwetsbaar ecosysteem dat door klimaatverandering, die zich daar meer manifesteert dan elders, wordt bedreigd. De noordpool is geen geïsoleerd gebied, het is sterk verbonden met de rest van de wereld

Een meeslepende ontdekkingstocht langs de boomgrens waarin de effecten van klimaatverandering voelbaar worden. 'Onze bomen zijn aan het verdwijnen: een verschrikkelijk beeld. Dit boek is een evocatieve, wijze en krachtige ontdekkingstocht naar wat dat zal betekenen voor de mensheid.' - Jay Griffiths, auteur van 'A Sideways Look at Time' De afgelopen 50 jaar krimpen de noordelijke sneeuwbossen in een rap tempo. Hier worden de geologische effecten van klimaatverandering voor het eerst pijnlijk zichtbaar. Ben Rawlence neemt ons mee langs die cruciale grenslijn - van Noorwegen naar Siberië, van Alaska tot Groenland - en combineert een reisverhaal met journalistiek en wetenschap. Hij portretteert 6 boomsoorten, hun mysterieuze werking op de lucht waar wij afhankelijk van zijn, en schetst een verontrustend toekomstbeeld. Bron: Flaptekst, uitgeversinformatie.

Tweede, geheel herziene, druk, oktober 2017 Theunis Piersma is hoogleraar trekvogelecologie in Groningen en waddenonderzoeker bij het Koninklijk Nederlands Instituut voor Onderzoek der Zee (NIOZ) op Texel. Hij is een internationale autoriteit op het gebied van (trek)vogels. In zijn vrije tijd doet hij in zijn woonplaats, het Friese Gaast, onderzoek naar huiszwaluwen. Een dorpsgenoot vroeg hem eens: 'Waar blijven onze zwaluwen in de winter, Theunis?' Die vraag was aanleiding voor een zoektocht: hoe overleven huiszwaluwen en waar overwinteren ze? Piersma is een geboren verteller en verstaat de kunst om ingewikkelde, wetenschappelijke materie op een begrijpelijke en onderhoudende manier over te dragen. Een literair verslag van een persoonlijke zoektocht, een ode aan de huiszwaluw.

The Lion Man is counted among the most significant discoveries in prehistoric archeology. The statuette - made from mammoth ivory from the Lone Valley near Ulm - is the largest known sculpture of Ice Age art. At nearly 40,000 years old, it is one of the oldest pieces of figurative art made by mankind. New excavations in the Stadel cave led archeologists to the surprising re-discovery of the original finding place of the statuette from the 1939 excavation- They were also able to retrieve numerous additional fragments from the figure. As a result, it was possible to further reassemble the Lion Man in the course of a complex restoration project. The project culminated in a special exhibition at the Ulmer Museum, which focuses on the Paleolithic statuette. This present companion volume also serves as the most current and comprehensive guide to Ice Age art and culture of the Swabian Jura.

This is a revised and updated version of Rhona Black's successful and highly acclaimed textbook. Aimed at students approaching the subject for the first time, The Elements of Palaeontology achieves an approach simple enough for beginning students, yet with sufficient depth and breadth of coverage for those wishing to delve further into the early history of life. The author deals systematically with all the groups of fossilised organisms: invertebrates and vertebrates, microfossils, plants and trace fossils, describing their morphology and dealing briefly with the biological aspects of palaeontology. The relevant technical terms are clearly defined and a glossary is included for each of the main invertebrate groups. In this second edition, a chapter on trace fossils has been added, the chapter on microfossils expanded, and a section on pollens included with the plants. In each case the superb illustrations have been added to, with the inclusion of many new electron micrographs.

Rivers have played an extraordinarily important role in creating the world in which we live. They create landscapes and provide water to people, plants and animals, nourishing both town and country. The flow of rivers has enthused poets and painters, explorers and pilgrims. Rivers have acted as cradles for civilization and agents of disaster; a river may be a barrier or a highway, it can bear trade and sediment, culture and conflict. A river may inspire or it may terrify. This Very Short Introduction is a celebration of rivers in all their diversity. Nick Middleton covers a wide and eclectic range of river-based themes, from physical geography to mythology, to industrial history and literary criticism. Worshipped and revered, respected and feared, rivers reflect both the natural and social history of our planet. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

The 1960s revealed a new and revolutionary idea in geological thought: that the continents drift with respect to one another. After having been dismissed for decades as absurd, the concept gradually became part of geology's basic principles. We now know that the Earth's crust and upper mantle consist of a small number of rigid plates that move, and there are significant boundaries between pairs of plates, usually known as earthquake belts.

Plate tectonics now explains much of the structure and phenomena we see today: how oceans form, widen, and disappear; why earthquakes and volcanoes are found in distinct zones which follow plate boundaries; how the great mountain ranges of the world were built. The impact of plate tectonics is studied closely as these processes continue: the Himalaya continues to grow, the Atlantic is widening, and new oceans are forming. In this Very Short Introduction Peter Molnar provides a succinct and authoritative account of the nature and mechanisms of plate tectonics and its impact on our understanding of Earth.
