"Abstract Barks: Geometric Dog Artistry" is a distinctive coloring book that presents an artistic convergence of man's best friend with the intriguing world of geometric abstraction. This collection consists of 50 pages, each featuring a unique and stylized depiction of different dog breeds. These illustrations reimagine beloved canines as compositions of geometric shapes, lines, and forms, creating a modern and abstract representation of each breed. From the smooth curves of a Dachshund to the angular form of a Husky, every page offers a unique blend of canine features with abstract art. Ideal for dog lovers and those who appreciate contemporary design, this book invites you to color outside the lines of conventional pet portraits, providing a creative and abstract exploration of dogs through the lens of geometric artistry.
Bark Beetles: Biology and Ecology of Native and Invasive Species provides a thorough discussion of these economically important pests of coniferous and broadleaf trees and their importance in agriculture. It is the first book in the market solely dedicated to this important group of insects, and contains 15 chapters on natural history and ecology, morphology, taxonomy and phylogenetics, evolution and diversity, population dynamics, resistance, symbiotic associations, natural enemies, climate change, management strategies, economics, and politics, with some chapters exclusively devoted to some of the most economically important bark beetle genera, including Dendroctonus, Ips, Tomicus, Hypothenemus, and Scolytus. This text is ideal for entomology and forestry courses, and is aimed at scientists, faculty members, forest managers, practitioners of biological control of insect pests, mycologists interested in bark beetle-fungal associations, and students in the disciplines of entomology, ecology, and forestry. Provides the only synthesis of the literature on bark beetles Features chapters exclusively devoted to some of the most economically important bark beetle genera, such as Dendroctonus, Ips, Tomicus, Hypothenemus, and Scolytus Includes copious color illustrations and photographs that further enhance the content
"The compilation of papers in this proceedings is based on a symposium sponsored by the Insect and Diseases Working Group (D5) at the 2007 Society of American Foresters (SAF) convention in Portland, Oregon. The selection of topics parallels the research priorities of the Western Bark Beetle Research Group (WBBRG) (USDA Forest Service, Research and Development), which had been recently formed at the time of the symposium. Reflecting a unique partnership within the Forest Service, each paper was jointly prepared by a research scientist with the WBBRG and one or more entomologists with Forest Health Protection (USDA Forest Service, State and Private Forestry). Among these papers is a description of the currently elevated impacts of bark beetles in the Western United States; descriptions of the current state of knowledge of bark beetle response to vegetation management and also to climate change; discussions of the complex interactions of bark beetles and fire and of the complex ecological and socioeconomic impacts of infestations; an overview of the use of semiochemical (behavioral chemicals)-based technology for conifer protection; and a case study exemplifying efforts to assess risks posed by nonnative invasive bark beetles." --
What to do with bark is a major question facing the wood conversion industries. Optimum utilization of bark residues demands appreciation of the complexity of bark and the extreme variation in chemical and physical properties between barks of different wood species. This report discusses bark structure, past and present utilization, and methods of upgrading bark both physically and chemically for increased utilization. Pertinent literature citations and continuing bibliographic sources of information on bark are included. Appended directories indicate sources of technical assistance and utilization equipment.
