Seeing fluorescent minerals up close for the first time is an exciting experience. The colors are so pure and the glow is so seemingly unnatural, that it is hard to believe they are natural rocks. Hundreds of glowing minerals are shown, including Aragonite, Celestine, Feldspar, Microcline, Picropharmacolite, Quartz, Spinel, Smithsonite, plus many more. But don't let the hard-to-pronounce names keep you away. Over 870 beautiful color photographs illustrate how fluorescent minerals look under UV light and in daylight, making this an invaluable field guide. Here are minerals from the United States, including mines in New Jersey, New York, Arizona, and California, as well as beautiful and unusual minerals from Canada, Mexico, Greenland, Italy, Sweden, and other places. Included are values, a comprehensive resources section, plus helpful advice on caring for, collecting, and displaying minerals. The field of collecting fluorescent minerals is relatively new and this is one of the most complete references available.

Stargazing from Game Reserves in Southern Africa o ers visitors to game and nature reserves an opportunity to discover the magni cence of the night skies without the distractions of city lights. However, the book has equal relevance for all skywatchers throughout southern Africa.

Readers are taken on a brief celestial ‘game drive’ and are then directed towards the ‘Big Five’ constellations of the night sky.  There are clear steps for navigating the skies, tracking the planets, and even spotting the moons of Jupiter.  This new edition features updated charts, colourful photos, illustrations and charts. Interesting fact boxes make for added interest and accessibility.

Written and revised by recognised authorities and expertly illustrated, the book also features useful tips and hints for star-watchers in any out-of-town location.

A thrilling face-to-face encounter with animals in their own environment – their elaborate displays, intimate lives, and extraordinary behaviour

Did you know that elephants give each other names, orangutans self-medicate, and rats giggle? Animal Behaviour is full of hundreds of stories that shed light on how animals navigate life in the wild.

Packed with vivid wildlife photography and action sequences, every aspect of animal life and behaviour is explored and explained – from courtship rituals and birth to hunting and death. An initial overview of animal anatomy and physiology reveals the science and biomechanics that underpin animal behaviour, while later chapters thematically break down the intricacies of animal feeding, development, communication, intelligence, learning, and other behavioural characteristics. Learn about play through river otters, see socialization among parrots at the riverbank, and catch prey with a fishing spider. Feature panels throughout the book explore the biology behind these traits, introduce case studies from the field, and highlight critical conservation issues facing these animals.

Animal Behaviour has been created in collaboration with internationally renowned zoologist and TV presenter Charlotte Uhlenbroek and a team of wildlife experts to ensure up-to-date and accurate information.

Skuif handel oor die evolusie van ons wêreld vanaf die begin van lewe tot in die toekoms. Die boek gee ’n ongelooflike oorsig van elke tydperk in die aarde se tektoniese geskiedenis. Hierdie verstommende visuele voorstelling van die aarde se geologiese geskiedenis beskryf die verskuiwing van landmassas en die ontwikkeling van die kontinente soos ons dit vandag ken.

Met pragtige wêreldkaarte en illustrasies wat die oorsprong van lewe uitbeeld en die aarde se moontlike toekoms vorspel, is Skuif die ideale gids tot ons planeet se geskiedenis. Martin Ince beskryf op toeganklike wyse wat die impak van geologiese veranderinge op die lewe op aarde is.

The written history and archaeological records of Central Scotland takes us back to Pictish times some 5,000 years ago. The geology of the area stretches back a further 400 million years. The oldest rocks are found near Lesmahagow and in the Pentland Hills. Known geologically as 'inliers'- small areas of rocks from an older age, surrounded by younger strata - these strata have yielded some of the oldest fish on earth and are highly prized for what they tell us about early life on the planet. Rocks of the Old Red Sandstone and the succeeding Carboniferous era underlie the rest of Central Scotland in almost equal measure. Explosive volcanic rocks, thick layers of lava, desert sandstones, limestones and productive coal measures make up this bedrock patchwork. Then, sometime later, a covering of ice, some two kilometres thick, blanketed the landscape. It sandpapered and burnished the bedrock into the familiar scenes we see today - our matchless Scottish landscape. The coal and iron ore which lay beneath the ground between Edinburgh and Glasgow provided the raw materials that drove the Industrial Revolution in Scotland, and the early focus on understanding the rocks beneath our feet was unsurprisingly initially concentrated on the most useful minerals resources.

Contains circular walks in the Cotswold countryside. Each one in this guide offers a chance to view the daily life of the riverbank animals, birds and fish. Another title from the Cotswold publisher, Reardon.

The south of Scotland has a long and turbulent geological past. Perhaps most notably, it marks the place where, 432 million years ago, an ocean, once as wide as the north Atlantic, was compressed by a convergence of ancient lands and then ceased to be. Deserts covered the land with thick layers of brick-red coloured rocks, known as the Old Red Sandstone, piled up and dumped by rivers and streams that crisscrossed the area. Around 432 million years ago, violent explosive volcanic activity gave rise to the prominent landscape features recognised today as the Eildon Hills. In later geological times, the area was blanketed with massive sand dunes, later compressed to create the building stones from which Dumfries, Glasgow and other towns and cities, were constructed. It is also the place where the modern science of geology was born. James Hutton, star of the Scottish Enlightenment, found inspiration from his study of the local rocks. Sites he described almost 250 years ago are still hailed as amongst the most historic and important rock exposures to be found anywhere in the world.
