Peterson Identification System
The Peterson Identification System is a practical method for the field identification of animals, plants and other natural phenomena. It was devised by ornithologist Roger Tory Peterson in 1934 for the first of his series of ''Field Guide''s (See Peterson Field Guides.) Peterson devised his system "so that live birds could be identified readily at a distance by their 'field marks' without resorting to the bird-in-hand characters that the early collectors relied on. During the last half century the binocular and the spotting scope have replaced the shotgun." As such, it both reflected and contributed to awareness of the emerging early environmental movement. Another application of this system was made when Roger Tory Peterson was enlisted in the US Army Corps of Engineers from 1943 to 1945. “...plane identification—the aircraft spotting technique—was based on Roger’s bird identification method-the Peterson system.”.Devlin, John C. and Naismith, Grace (1977), “The World of ...

Animal Identification
Animal identification using a means of marking is a process done to identify and track specific animals. It is done for a variety of reasons including verification of ownership, biosecurity control, and tracking for research or agricultural purposes. History Individual identification of animals by means of body markings has been practiced for over 3,800 years, as stated in Code of Hammurabi. The first official identification systems are documented as far as the 18th century. In Uruguay for instance maintained at that time a register of hot brands. Methods Birds * Leg rings * Wing tags * Microchip implants (parrots) * Telemetry (falconry birds) Sheep * Freeze branding * Branding (hot-iron) * Collar * Earmarking * Ear tags (non-electronic) * Ear tags (electronic) * Semi-permanent paint Pigs * Collars (electronic and non-electronic) * Earmarking * Ear tags (non-electronic) * Ear tags (electronic) * Semi-permanent paint * Tattoo Horses * Collars (non-electronic) * Br ...

Ornithologist
Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them." Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across life forms, and the number of scientists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roger Tory Peterson
Roger Tory Peterson (August 28, 1908 – July 28, 1996) was an American naturalist, ornithologist, illustrator and educator, and one of the founding inspirations for the 20th-century environmental movement. Background Peterson was born in Jamestown, New York, a small, industrial city in southwestern New York, on August 28, 1908. His father, Charles Gustav Peterson, was an immigrant from Sweden who came to America as an infant. At the age of ten, Charles Peterson lost his father to appendicitis and was sent off to work in the mills. After leaving the mills, he earned his living as a traveling salesman. Roger's mother, Henrietta Badar, was an immigrant, at the age of four, of German and Polish extraction, who grew up in Rochester, New York. She went to a teachers' college, and was teaching in Elmira, New York, when she met Charles. The two married, and moved to Jamestown, where Charles took a job at a local furniture factory. Roger's middle name honors his Uncle Tory who was liv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Peterson Field Guides
The Peterson Field Guides (PFG) are a popular and influential series of American field guides intended to assist the layman in identification of birds, plants, insects and other natural phenomena. The series was created and edited by renowned ornithologist Roger Tory Peterson (1908–1996). His inaugural volume was the classic 1934 book ''A Field Guide to the Birds'', published (as were all subsequent volumes) by the Houghton Mifflin Company. The PFG series utilized what became known as the Peterson Identification System, a practical method for field identification which highlights readily noticed visual features rather than focusing on the technical features of interest to scientists. The series both reflected and contributed to awareness of the emerging environmental movement. Most books in this series use a section of plates of drawings (usually reduced from commissioned paintings) rather than photographs of the subject species, grouped at the center of the book. This allows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environmental Movement
The environmental movement (sometimes referred to as the ecology movement), also including conservation and green politics, is a diverse philosophical, social, and political movement for addressing environmental issues. Environmentalists advocate the just and sustainable management of resources and stewardship of the environment through changes in public policy and individual behaviour. In its recognition of humanity as a participant in (not enemy of) ecosystems, the movement is centered on ecology, health, and human rights. The environmental movement is an international movement, represented by a range of organizations, from enterprises to grassroots and varies from country to country. Due to its large membership, varying and strong beliefs, and occasionally speculative nature, the environmental movement is not always united in its goals. The movement also encompasses some other movements with a more specific focus, such as the climate movement. At its broadest, the mov ...

Amateur
An amateur () is generally considered a person who pursues an avocation independent from their source of income. Amateurs and their pursuits are also described as popular, informal, self-taught, user-generated, DIY, and hobbyist. History Historically, the amateur was considered to be the ideal balance between pure intent, open mind, and the interest or passion for a subject. That ideology spanned many different fields of interest. It may have its roots in the ancient Greek philosophy of amateur athletes competing in the Olympics. The ancient Greek citizens spent most of their time in other pursuits, but competed according to their natural talents and abilities. The "gentleman amateur" was a phenomenon among the gentry of Great Britain from the 17th century until the 20th century. With the start of the Age of Reason, with people thinking more about how the world works around them, (see science in the Age of Enlightenment), things like the cabinets of curiosities, and t ...

Laymen
In religious organizations, the laity () consists of all members who are not part of the clergy, usually including any non-ordained members of religious orders, e.g. a nun or a lay brother. In both religious and wider secular usage, a layperson (also layman or laywoman) is a person who is not qualified in a given profession or does not have specific knowledge of a certain subject. The phrase " layman's terms" is used to refer to plain language that is understandable to the everyday person, as opposed to specialised terminology understood only by a professional. Some Christian churches utilise lay preachers, who preach but are not clergy. The Church of Jesus Christ of Latter-day Saints uses the term ''lay priesthood'' to emphasise that its local congregational leaders are unpaid. Terms such as ''lay priest'', ''lay clergy'' and ''lay nun'' were once used in certain Buddhist cultures to indicate ordained persons who continued to live in the wider community instead of retiring to ...

Field Guide
A field guide is a book designed to help the reader identify wildlife (flora or fauna) or other objects of natural occurrence (e.g. rocks and minerals). It is generally designed to be brought into the " field" or local area where such objects exist to help distinguish between similar objects. Field guides are often designed to help users distinguish animals and plants that may be similar in appearance but are not necessarily closely related. It will typically include a description of the objects covered, together with paintings or photographs and an index. More serious and scientific field identification books, including those intended for students, will probably include identification keys to assist with identification, but the publicly accessible field guide is more often a browsable picture guide organized by family, colour, shape, location or other descriptors. History Popular interests in identifying things in nature probably were strongest in bird and plant guides. Perha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Literature
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life. Energy processing is also important to life as it allows organisms to move, grow, and reproduce. Finally, all organisms are able to regulate their own internal environments. Biologists are able to study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations.Based on definition from: Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. Like other scientists, biologists use the scientific m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
