Insects on Nettles PDF Author: B. N. K. Davis
Publisher: Pelagic Publishing Limited
ISBN: 9780855462833
Category : Nature
Languages : en
Pages : 0

Book Description
Stinging nettles harbour a characteristic community of insects that are widespread, abundant, and rewarding to study. This book describes the natural history of the insects in that community, and describes the way they coexist using different parts of a stinging nettle plant. It discusses the feeding habits of herbivores and predatory insects, and the parasites that feed on them, as well as the seasonal distribution of the life cycles of the different members of the community. For a nettle-dwelling insect species, a nettle patch is an island in a sea of unsuitable habitat, and this book discusses the relationship between the size and isolation of the nettle patch and the nature of its community. Keys are provided for identification, and many of the commoner species are illustrated in colour. Techniques are described for investigating insect fauna. A three page addendum draws attention to the changes in the nettle community that may be expected to result from global warming.

Book Description
"It's up to every single one of us to do our bit for wildlife, however small our gardens, and The Butterfly Brothers know just how that can be achieved." Alan Titchmarsh Join the rewilding movement and share your outdoor space with nature. We all have the potential to make the world a little greener. Wild Your Garden, written by Jim and Joel Ashton (aka "The Butterfly Brothers"), shows you how to create a garden that can help boost local biodiversity. Transform a paved-over yard into a lush oasis, create refuges to welcome and support native species, or turn a high-maintenance lawn into a nectar-rich mini-meadow to attract bees and butterflies. You don't need specialist knowledge or acres of land. If you have any outdoor space, you can make a difference to local wildlife, and reduce your carbon footprint, too. "Wildlife gardening is one of the most important things you can do as an individual for increasing biodiversity and mitigating the effects of climate change. From digging a pond to planting a native hedge, the Butterfly Brothers can help you every step of the way." Kate Bradbury

A Natural History of Nettles

A Natural History of Nettles PDF Author: Dr. Keith G R Wheeler
Publisher: Trafford Publishing
ISBN: 1466981024
Category : Gardening
Languages : en
Pages : 316

Book Description
The first book ever on the much maligned nettles of the world presents a story of these followers of mankind and his cattle throughout history. This study centres on the most abundant and sub-cosmopolitan common stinging nettle (Urtica dioica), but also deals with other nettles throughout the world. Tropical tormentors rich in species include the notorious nettle trees with their formidable stings which fascinated the Europeans after their discovery by botanists on the round-the-world trips of exploration in the 17-19th centuries. Many people on their travels will have met the nettle trees of the Indo-Malay region and other stinging nettles in North and South America, India, etc., which sting and have beautiful flowers but are called nettles; these are also dealt with. The first microscopists and their descriptions of the beautiful stinging hair; the uncovering of the mechanism of its action and the more recent elucidation of the toxins causing the characteristic symptoms is a fascinating one and takes up 3 chapters. The book includes the 100 major scientific works published on the common stinging nettle and never brought to the notice of the general public before. The author spent six years studying the ecology of the nettle patch, its invertebrate herbivores (mainly insects) and vertebrate herbivores (cattle, deer, etc.,) and their interactions with other plants: its secret life is recorded in line drawings and photographs (1000+ individual items). It was not possible to publish these in colour but they are in full colour on a CD-ROM (300 dpi) at the back of the book. Covered also are nettle folklore, fibre use in World War I & II, as a food, fodder, herbal medicine, growth as a competitor plant, habitats, sex (unique exploding stamens), breeding systems, variation, evolution etc.!! Some the world's most beautiful butterflies would not exist without nettles.

Nature Obscura

Nature Obscura PDF Author: Kelly Brenner
Publisher: Mountaineers Books
ISBN: 1680512080
Category : Nature
Languages : en
Pages : 229

Book Description
With wonder and a sense of humor, Nature Obscura author Kelly Brenner aims to help us rediscover our connection to the natural world that is just outside our front door--we just need to know where to look. Through explorations of a rich and varied urban landscape, Brenner reveals the complex micro-habitats and surprising nature found in the middle of a city. In her hometown of Seattle, which has plowed down hills, cut through the land to connect fresh- and saltwater, and paved over much of the rest, she exposes a diverse range of strange and unknown creatures. From shore to wetland, forest to neighborhood park, and graveyard to backyard, Brenner uncovers how our land alterations have impacted nature, for good and bad, through the wildlife and plants that live alongside us, often unseen. These stories meld together, in the same way our ecosystems, species, and human history are interconnected across the urban environment.

The Sting of the Wild

The Sting of the Wild PDF Author: Justin O. Schmidt
Publisher: Johns Hopkins University Press
ISBN: 1421425645
Category : Science
Languages : en
Pages : 281

Book Description
The “King of Sting” describes his adventures with insects and the pain scale that’s made him a scientific celebrity. Silver, Science (Adult Non-Fiction) Foreword INDIES Award 2017 Entomologist Justin O. Schmidt is on a mission. Some say it’s a brave exploration, others shake their heads in disbelief. His goal? To compare the impacts of stinging insects on humans, mainly using himself as the test case. In The Sting of the Wild, the colorful Dr. Schmidt takes us on a journey inside the lives of stinging insects. He explains how and why they attack and reveals the powerful punch they can deliver with a small venom gland and a “sting,” the name for the apparatus that delivers the venom. We learn which insects are the worst to encounter and why some are barely worth considering. The Sting of the Wild includes the complete Schmidt Sting Pain Index, published here for the first time. In addition to a numerical ranking of the agony of each of the eighty-three stings he’s sampled so far, Schmidt describes them in prose worthy of a professional wine critic: “Looks deceive. Rich and full-bodied in appearance, but flavorless” and “Pure, intense, brilliant pain. Like walking over flaming charcoal with a three-inch nail embedded in your heel.” Schmidt explains that, for some insects, stinging is used for hunting: small wasps, for example, can paralyze huge caterpillars for long enough to lay eggs inside them, so that their larvae emerge within a living feast. Others are used to kill competing insects, even members of their own species. Humans usually experience stings as defensive maneuvers used by insects to protect their nest mates. With colorful descriptions of each venom’s sensation and a story that leaves you tingling with awe, The Sting of the Wild’s one-of-a-kind style will fire your imagination.

Publisher: Chronicle Books
ISBN: 1616896175
Category :
Languages : en
Pages : 226

Book Description
In this eloquent plea for compassion and respect for all species, journalist and gardener Nancy Lawson describes why and how to welcome wildlife to our backyards. Through engaging anecdotes and inspired advice, profiles of home gardeners throughout the country, and interviews with scientists and horticulturalists, Lawson applies the broader lessons of ecology to our own outdoor spaces. Detailed chapters address planting for wildlife by choosing native species; providing habitats that shelter baby animals, as well as birds, bees, and butterflies; creating safe zones in the garden; cohabiting with creatures often regarded as pests; letting nature be your garden designer; and encouraging natural processes and evolution in the garden. The Humane Gardener fills a unique niche in describing simple principles for both attracting wildlife and peacefully resolving conflicts with all the creatures that share our world.

Insect-Plant Biology

Insect-Plant Biology PDF Author: Louis M. Schoonhoven
Publisher: Oxford University Press
ISBN: 019852594X
Category : Science
Languages : en
Pages : 441

Book Description
"Half of all insect species are dependent on living plant tissues, consuming about 10% of plant annual production in natural habitats and an even greater percentage in agricultural systems, despite sophisticated control measures. Plants are generally remarkably well-protected against insect attack, with the result that most insects are highly specialized feeders. The mechanisms underlying plant resistance to invading herbivores on the one side, and insect food specialization on the other, are the main subjects of this book. For insects these include food-plant selection and the complex sensory processes involved, with their implications for learning and nutritional physiology, as well as the endocrinological aspects of life cycle synchronization with host plant phenology. In the case of plants exposed to insect herbivores, they include the activation of defence systems in order to minimize damage, as well as the emission of chemical signals that may attract natural enemies of the invading herbivores and may be exploited by neighbouring plants that mount defences as well." "Insect-Plant Biology discusses the operation of these mechanisms at the molecular and organismal levels, in the context of both ecological interactions and evolutionary relationships. In doing so, it uncovers the highly intricate antagonistic and mutualistic interactions that have evolved between plants and insects. The book concludes with a chapter on the application of our knowledge of insect-plant interactions to agricultural production." "This multidisciplinary approach will appeal to students in agricultural entomology, plant sciences, ecology, and indeed anyone interested in the principles underlying the relationships between the two largest groups of organisms on earth: plants and insects."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Pages : 100

Book Description
Plants from the genera Urtica, often better known as the stinging nettle, can be distinguished by their stinging hairs, and in some species, their serrated leaf edges. Historical records of the various uses of Urtica date back to at least the Bronze Age (3000-2000 BC). Nettles have traditionally been used as a nutritious food source particularly in
