Packed with outstanding photographs, this practical, compact yet comprehensive reference is the definitive guide to all 139 amphibian species found in the Western Palearctic and adjacent regions. From familiar frogs and toads to striking salamanders and newts, the detailed text describes each species' appearance, habitat and behaviour, and includes useful information on their classifications, ecology and life cycles. Grouped by families for ease of use, every account includes an accurate distribution map and colour photographs annotated with crucial details to help swiftly identify species in the field. Written by field biologist Christophe Dufresnes, this is the ultimate photographic guide for amateurs and expert herpetologists alike.
Amphibians of Europe, North Africa and the Middle East
This photographic field guide is a practical, compact and yet exhaustive reference covering all European amphibian species, from familiar frogs and toads, to exotic salamanders and caecilians. Amphibians of Britain and Europe covers all 127 species found in the region, from familiar frogs and toads, to exotic salamanders and caecilians. Each species account describes their appearance, habitat and behavior, and includes accurate and up-to-date distribution maps, and photos that emphasize key identification features, assisting rapid identification in the field. Introductory sections describe the general biology of amphibians, their classification, ecology, life-history cycles, diversity and conservation. The species are then described in sections organized by family, with each account covering points of interest such as behavior, subspecies, eggs and tadpoles, and dimorphism, all in rich photographic detail.
A Wildlife Guide to Georgia
Considered by many to be one of the most interesting, varied and biodiverse destinations in the Western Palearctic, Georgia has a great deal to offer for the naturalist-traveller. This guidebook is the first of its kind for the area, not only giving information on where to go birding, but also covering mammals, reptiles, butterflies, dragonflies, flora and numerous other items of note. Since the Rose Revolution in 2003, Georgia has gained popularity among western travellers. With the Caucasus being one of the richest wildlife hotspots in the world, featuring a high degree of endemism – not to mention the hospitable people, dramatic landscapes and last but not least the wonderful cuisine – it makes an excellent travel destination. This book is the practical guide for any nature enthusiast considering a visit to Georgia – from the serious birder to the butterfly fanatic, to the traveller with a general interest in the natural world. Packed with photographs and tips, it also contains many practical maps and suggested routes. An indispensable companion for any journey to the region.
The Evolution of Sex Determination
Sexual reproduction is a fundamental aspect of life. It is defined by the occurrence of meiosis and the fusion of two gametes of different sexes or mating types. Sex-determination mechanisms are responsible for the sexual fate and development of sexual characteristics in an organism, be it a unicellular alga, a plant, or an animal. In many cases, sex determination is genetic: males and females have different alleles or different genes that specify their sexual morphology. In animals, this is often accompanied by chromosomal differences. In other cases, sex may be determined by environmental (e.g. temperature) or social variables (e.g. the size of an organism relative to other members of its ...
Wölfe in der Schweiz
Vor mehr als 25 Jahren sind die ersten Wölfe nach langer Abwesenheit wieder in der Schweiz gesichtet worden. Die Irritationen in der Berglandwirtschaft waren gross. Und bis heute wird kontrovers diskutiert, ob der Wolf oder auch andere Raubtiere hier wieder ein Existenzrecht haben sollen. Umso mehr, als sich mittlerweile über hundert Tiere, teils in Rudeln, in verschiedenen Teilen des Landes etabliert haben und immer öfter auch im Mittelland und im Jura gesichtet werden. Der Wolf polarisiert. Die Autoren haben sich mit Wildhütern, Behörden, Fachstellen und Nutztierhaltern ausgetauscht. Ihr Buch lotet die vielschichtigen, sich verändernden und oft verborgenen Beziehungen zwischen Menschen und wilden Tieren aus. Es erkundet nicht die wildtierbiologischen Aspekte des Wolfs, sondern beleuchtet Fakten und Emotionen. Damit trägt es zum besseren Verständnis der Konflikte rund um das Nebeneinander von Mensch, Nutztier und Wolf bei.
Amphibians of North Africa
Amphibians of North Africa is a comprehensive compilation of available data on the amphibians and reptiles found in various ecosystems across North West Africa and parts of the Mediterranean region. It is essential to identifying and understanding the ecological role of regional herpetofauna and its conservational importance. It examines the biological origins and diversity of amphibians in North Africa, along with their diverse ecosystems, including deserts, grasslands and subtropical forests. The book features detailed descriptions of the adult and larvae stages of species, such as the North African fire salamander, the common painted frog, Brongersma's toad and the Mediterranean tree frog. This book is a vital resource for herpetology and ecology students and researchers, helping them identify, understand and conserve these amphibians and reptiles in their various habitats across the North African and Mediterranean regions.
Fundamental Aspects of Turbulent Flows in Climate Dynamics
"This book collects the text of the lectures given at the Les Houches Summer School on "Fundamental aspects of turbulent flows in climate dynamics", held in August 2017. Leading scientists in the fields of climate dynamics, atmosphere and ocean dynamics, geophysical fluid dynamics, physics and non-linear sciences present their views on this fast growing and interdisciplinary field of research, by venturing upon fundamental problems of atmospheric convection, clouds, large scale circulation, and predictability. Climate is controlled by turbulent flows. Turbulent motions are responsible for the bulk of the transport of energy, momentum, and water vapor in the atmosphere, which determine the di...
Field Guide to the Amphibians and Reptiles of Britain and Europe
Illustrated with over 370 colour artworks and over 200 colour photographs.
The Hawkmoths of the Western Palaearctic
A detailed study of 57 sphingid species occurring in Europe (Ireland to the Urals), North Africa and the Middle East, placing particular emphasis on ecological factors governing population and distribution. The colour plates depict adults of all species, larvae of 40 species and 5 subspecies, and 13 types of habitat. A major work, of interest to lepidopterists and conservationists.
