Into The Treeline

Alpine treelines mark the low-temperature limit of tree growth and occur in mountains world-wide. Presenting a companion to his book Alpine Plant Life, Christian Körner provides a global synthesis of the treeline phenomenon from sub-arctic to equatorial latitudes and a functional explanation based on the biology of trees. The comprehensive text approaches the subject in a multi-disciplinary way by exploring forest patterns at the edge of tree life, tree morphology, anatomy, climatology and, based on this, modelling treeline position, describing reproduction and population processes, development, phenology, evolutionary aspects, as well as summarizing evidence on the physiology of carbon, water and nutrient relations, and stress physiology. It closes with an account on treelines in the past (palaeo-ecology) and a section on global change effects on treelines, now and in the future. With more than 100 illustrations, many of them in colour, the book shows alpine treelines from around the globe and offers a wealth of scientific information in the form of diagrams and tables.

New Zealand's alpine environment is challenging, not only for the humans who explore it but for the plants and animals that inhabit it. The extremes of temperature, short summers and high rates of erosion make for an uncertain environment, and the flora and fauna have evolved and adapted to it in interesting ways. Above the Treeline: A nature guide to the New Zealand mountains is a guide to the natural history of these fascinating ecosystems. It is the first book to be published that brings together the range of flora and fauna that inhabit the alpine environment. As well as our unique alpine plants, which constitute the majority of the book, this guide includes birds; frogs and lizards; butterflies, moths, grasshoppers, beetles and other invertebrates; and mosses and lichens. An informative introduction is followed by descriptions of more than 850 species, illustrated by approximately 1000 colour photographs. Written by eminent botanist and conservationist Sir Alan Mark, . . .

This volume focuses on interaction between vegetation, relief, climate, soil and fauna in the treeline ecotone, and the effects of climate change and land use in North America and Europe.

The perfect hiker's companion for any naturalist interested in the lichens of the northeastern mountaintops

Presents full-color illustrated photographs that describes the botany, history, mythology, and folklore of some of the world's most unique trees including California's giant redwood.

Diana Beresford-Kroeger's startling insights into the hidden life of trees have sparked a quiet revolution. In this captivating account, she shows us how forests can not only heal us, but can also save the planet.

The story of Al Howie is a remarkable and at times unbelievable adventure into the heart of the longest races in the world with one of modern history's most eccentric ultra-marathon runners. If you ran 7295 kilometres across Canada in 72 days, wearing three-ounce racing flats, then two weeks later took on the longest certified race on Earth and broke the world record (which happened to be your own), what would you be? Likely an alien. If you won 24-hour races and three-, six-, and seven-day races several times a year in your mid-40s, and ran marathons just for training, what would they call you? Crazy for sure. If you were forever broke and shipped your clothes on buses in order to run free of baggage for thousands of kilometres just to get to races, you'd be institutionalized. And if you did all these things and were institutionalized for the last 15 years of your life, you would be Al Howie. Al Howie was an eccentric among the extreme runners in the ultra-marathon world, and his life was as enigmatic as his runs. Based on interviews with Howie himself during his final two years (he died in 2016), Jared Beasley's book takes the reader into the amazing and complex world of an astounding figure in modern sports history.

The alpine treeline ecotone (ATE) is an area of transition high on mountains where closed canopy forests from lower elevations give way to the open alpine tundra and rocky expanses above. Alpine tundra is an island biome and its ecotone with forest is subject to change, and like oceanic islands, alpine tundra is subject to invasion – or the upward advance of treeline. The invasion of tundra by trees will have consequences for the tundra biome as invasion does for other island flora and fauna. To examine the invasibility of tundra we take a plant’s-eye-view, wherein the local conditions become extremely important. Among these local conditions, we find geomorphology to be exceptionally important. We concentrate on aspects of microtopography (and microgeomorphology) and microclimate because these are the factors that matter: from the plant’s-eye-view, but we pay attention to multiple scales. At coarse scales, snow avalanches and debris flows are widespread and create “disturbance treelines whose elevation is well below those controlled by climate. At medium scales, turf-banked terraces create tread-and-riser topography that is a difficult landscape for a tree seedling to survive upon because of exposure to wind, dryness, and impenetrable surfaces. At fine scales, turf exfoliation of the fronts of turf-banked risers, and boulders, offer microsites where tree seedlings may find shelter and are able to gain a foothold in the alpine tundra; conversely, however, surfaces of needle-ice pans and frost heaving associated with miniature patterned ground production are associated with sites inimical to seedling establishment or survival. We explicitly consider how local scale processes propagate across scales into landscape patterns. The objective of this book is to examine the controls on change at alpine treeline. All the papers are focused on work done in Glacier National Park, Montana, USA. Although any one place is limiting, we are able to examine the alpine treeline here in some detail – and an advantage is that the treeline ecotone in Glacier National Park is quite variable in itself due to the underlying variability in geomorphology at multiple scales. This book will provide insights into an important ecological phenomenon with a distinctly geomorphic perspective. The editors collectively have over 100 years of experience in working in geomorphology, biogeography, and ecology. They also have each worked on research in Glacier National Park for several decades. The book will be a reference for a variety of professionals and students, both graduate and undergraduate, with interests in Physical Geography, Geomorphology, Ecology, and Environmental Science. Because of the importance of the alpine treeline ecotone for recreation and aesthetic interests in mountain environments, wildland and park managers will also use this book. * Subject matter: geomorphology at alpine treeline* Expertise of contributors: each editor brings over 25 years of experience in studies of ecotones and geomorphology, and collectively over 100 years of experience in Glacier National Park* Changing alpine treeline examines climate change

One educator's story detailing a cross-Canada run to inspire students and teachers to get outside and experience the benefits and beauty of nature. You'd think starting a non-profit organization aimed at getting young people to spend less time in front of screens and more time outside would be difficult enough. But with a decrepit support vehicle housing two dogs that despised each other, a good friend who left after five months, a lot of peanut butter, and a hope to inspire thousands of students, Colin Harris decided to start this journey by running 7600 kilometres, the equivalent of 181 marathons, across Canada. And to ensure this was a truly Canadian venture, he started in the bleak and snowy month of January. Take Me Outside is Colin's story of spending nine months running from St. John's, Newfoundland, to Victoria, British Columbia, visiting over 80 schools along the way to engage with 20,000 students about the importance of spending time outside learning, playing, and exploring in the Canadian landscape. With one of the biggest and best backyards in the world, people across Canada are spending the vast majority of their time inside. Yet, our identity as Canadians has always been rooted in our relationship with the outdoors. This wildly entertaining book not only recounts what it's like to run across the world's second-largest country but also implores readers of all ages to reignite their connection with the natural world.
