Conservation biology is the management of nature and of Earth 's biodiversity with the aim of protecting speciestheir habitatsand ecosystems from excessive rates of extinction and the erosion of biotic interactions. The conservation ethic principles of conservation biology pdf download based on the findings of conservation biology. Wilcox and Michael E. The meeting was prompted by the concern over tropical deforestationprinciples of conservation biology pdf download, disappearing species, eroding genetic diversity within species.
The inherent multidisciplinary basis for conservation biology has led to new subdisciplines including conservation social science, conservation behavior and conservation physiology. The rapid decline of established biological systems around the world means that conservation biology is often referred to as a "Discipline with a deadline".
Conservation biologists research and educate on the trends and process of biodiversity lossspecies extinctionsand the negative effect these are having on our capabilities to sustain the well-being of human society.
Conservation biologists work in the field and office, in government, universities, non-profit organizations and industry. The topics of their research are diverse, because this is an interdisciplinary network with professional alliances in the biological as well as social sciences. Those dedicated to the cause and profession advocate for a global response to the current biodiversity crisis based on moralsethicsand scientific reason.
Organizations and citizens are responding to the biodiversity crisis through conservation action plans that direct research, monitoring, and education programs that engage concerns at local through global scales. Conscious efforts to conserve and protect global biodiversity are a recent phenomenon. Resource ethics grew out of necessity through direct relations with nature. Regulation or communal restraint became necessary to prevent selfish motives from taking more than could be locally principles of conservation biology pdf download, therefore compromising the long-term supply for the rest of the community.
From this principle, conservation biologists can trace communal resource based ethics throughout cultures as a solution to communal resource conflict. These rules were guided by clan elders who knew lifelong details of each river and stream they managed. The Mauryan emperor Ashoka around B. Conservation ethics are also found in early religious and philosophical writings.
Wilderness was denigrated while agricultural development was praised. Natural history was a major preoccupation in the 18th century, with grand expeditions and the opening of popular public displays in Europe and North America. By there were natural history museums in Germanyin Great Britainprinciples of conservation biology pdf download, in the United Statesand in France. Before Charles Darwin set sail on HMS Beaglemost people in the world, including Darwin, believed in special creation and that all species were unchanged.
He proposed in his 44 volume natural history book that species evolve due to environmental influences. Erasmus Darwin noted that some species have vestigial structures which are anatomical structures that have no apparent function in the species currently but would have been useful for the species' ancestors.
By the early 19th century biogeography was ignited through the efforts of Alexander von HumboldtCharles Lyell and Charles Darwin. The modern roots of conservation biology can be found in the late 18th-century Enlightenment period particularly in England and Scotland. Scientific conservation principles were first practically applied to the forests of British India.
The conservation ethic that began to evolve included three core principles: that human activity damaged the environmentthat there was a civic duty to maintain the environment for future generations, and that scientific, empirically based methods should be applied to ensure this duty was carried out, principles of conservation biology pdf download.
Sir James Ranald Martin was prominent in promoting this ideology, publishing many medico-topographical reports that demonstrated the scale of damage wrought through large-scale deforestation and desiccation, and lobbying extensively for the institutionalization of forest conservation activities in British India through the establishment of Forest Departments. The Madras Board of Revenue started local conservation efforts inheaded by Alexander Gibsona professional botanist who systematically adopted a forest conservation program based on scientific principles.
This was the first case of state conservation management of forests in the world. The term conservation came into widespread use in the late 19th century and referred to the management, mainly for economic reasons, of such natural resources as timberfish, game, topsoilpasturelandand minerals. In addition it referred to the preservation of forests forestrywildlife wildlife refugeparkland, wildernessand watersheds.
This period also saw the passage of the first conservation legislation and the establishment of the first nature conservation societies. The Sea Birds Preservation Act of was passed in Britain as the first nature protection law in the world [38] after extensive lobbying from the Association for the Protection of Seabirds [39] and the respected ornithologist Alfred Newton.
One of the first conservation societies was the Royal Society for the Protection of Birdsprinciples of conservation biology pdf download, founded in in Manchester [42] as a protest group campaigning against the use of great crested grebe and kittiwake skins and feathers in fur clothing. This meeting led to the formation of the Society for the Promotion of Nature Reserves, which later became the Wildlife Trusts. In the United Statesthe Forest Reserve Act of gave the President power to set aside forest reserves from the land in the public domain.
A series of national forests and preserves were established by Theodore Roosevelt from to In the 20th century, Canadian civil servants, including Charles Gordon Hewitt [48] and James Harkin spearheaded the movement toward wildlife conservation. In the midth century, efforts arose to target individual species for conservation, notably efforts in big cat conservation in South America led by the New York Zoological Society.
Notably the United Nations acted to conserve sites of outstanding cultural or natural importance to the common heritage of mankind. As ofa total of sites are listed: cultural, natural.
The first country to pursue aggressive biological conservation through national legislation was the United States, which passed back to back legislation in the Endangered Species Act [55] and National Environmental Policy Act[56] which together injected major funding and protection measures to large-scale habitat protection and threatened species research. Other conservation developments, however, have taken hold throughout the world. India, for example, passed the Wildlife Protection Act of Ina significant development was the emergence of the urban conservation movement.
A local organization was established in BirminghamUKa development followed in rapid succession in cities across the UK, then overseas. Although perceived as a grassroots movementits early development was driven by academic research into urban wildlife. Initially perceived as radical, the movement's view of conservation being inextricably linked with other human activity has now become mainstream in conservation thought.
Considerable research effort is now directed at urban conservation biology. The Society for Conservation Biology originated in Bymost of the countries of the world had become committed to the principles of conservation of biological diversity with the Convention on Biological Diversity ; [58] subsequently many countries began programmes of Biodiversity Action Plans to identify and conserve threatened species within their borders, as well as protect associated habitats.
The late s saw increasing professionalism in the sector, with the maturing of organisations such as the Institute of Ecology and Environmental Management and the Society for the Environment. Sinceprinciples of conservation biology pdf download, the concept of landscape scale conservation has risen to prominence, with less emphasis being given to single-species or even single-habitat focused actions.
Instead an ecosystem approach is advocated by most mainstream conservationists, although concerns have been expressed by those working to protect some high-profile species. Ecology has clarified the workings of the biosphere ; i. The burgeoning human population and principles of conservation biology pdf download agricultureindustryand the ensuing pollution, have demonstrated how easily ecological relationships can be disrupted.
Extinction rates are measured in a variety of ways. Conservation biologists measure and apply statistical measures of fossil records[1] [60] rates of habitat lossand a multitude of other variables such as loss principles of conservation biology pdf download biodiversity as a function of the rate of habitat loss and site occupancy [61] to obtain such estimates. The current background extinction rate is estimated to be one species every few years.
The measure of ongoing species loss is made more complex by the fact that most of the Earth's species have not been described or evaluated. Estimates vary greatly on how many species actually exist estimated range: 3,, [65] to how many have received a species binomial estimated range: 1.
Systematic conservation planning is an effective way to seek and identify efficient and effective types of reserve design to capture or sustain the highest priority biodiversity values and to work with communities in support of local ecosystems. Margules and Pressey identify six interlinked stages in the systematic planning approach: [68].
Conservation biologists regularly prepare detailed conservation plans for grant proposals or to effectively coordinate their plan of action and to identify best management practices e. Systematic strategies generally employ the services of Geographic Information Principles of conservation biology pdf download to assist in the decision making process.
Conservation physiology was defined by Steven J. Cooke and colleagues as: 'An integrative scientific discipline applying physiological concepts, tools, and knowledge to characterizing biological diversity and its ecological implications; understanding and predicting how organisms, populations, and ecosystems respond to environmental change and stressors; and solving conservation problems across the broad range of taxa i.
Physiology is considered in the broadest possible terms to include functional and mechanistic responses at all scales, and conservation includes the development and refinement of strategies to rebuild populations, restore ecosystems, inform conservation policy, generate decision-support tools, and manage natural resources. The Principles of conservation biology pdf download for Conservation Biology is a global community of conservation professionals dedicated to advancing the science and practice of conserving biodiversity.
Conservation biology as a discipline reaches beyond biology, into subjects such as philosophylaweconomicshumanitiesartsanthropologyand education. Conservationists introduce bias when they support policies using qualitative description, such as habitat degradationor healthy ecosystems. Conservation biologists advocate for reasoned and sensible management of natural resources and do so with a disclosed combination of sciencereasonlogicand values in their conservation management plans. There is a movement in conservation biology suggesting a new form of leadership is needed to mobilize conservation biology into a more effective discipline that is able to communicate the full scope of the problem to society at large.
The concept is based on a new philosophy or leadership theory steering away from historical notions of power, authority, and dominance. Adaptive conservation leadership is reflective and more equitable as it applies to any member of society who can mobilize others toward meaningful change using communication techniques that principles of conservation biology pdf download inspiring, purposeful, and collegial.
Adaptive conservation leadership and mentoring programs are being implemented by conservation biologists through organizations such as the Aldo Leopold Leadership Program.
Conservation may be classified as either in-situ conservationprinciples of conservation biology pdf download is protecting an endangered species in its natural habitator ex-situ conservationwhich occurs outside the natural habitat, principles of conservation biology pdf download.
Ex-situ conservation, on the other hand, involves protection outside of an organism's natural habitat, such as on reservations or in gene banks, in circumstances where viable populations may not be present in the natural habitat.
Also, non-interference may be used, which is termed a preservationist method. Preservationists advocate for giving areas of nature and species a protected existence that halts interference from the humans. Some preservationists emphasize the potential of biodiversity in a world without humans. Conservation biologists are interdisciplinary researchers that practice ethics in the biological and social sciences.
Chan states [73] that conservationists must advocate for biodiversity and can do so in a scientifically ethical manner by not promoting simultaneous advocacy against other competing values. A conservationist may be inspired by the resource conservation ethic[7] : 15 which seeks to identify what measures will deliver "the greatest good for the greatest number of people for the longest time.
Aldo Leopold was a classical thinker and writer on such conservation ethics whose philosophy, ethics and writings are still valued and revisited by modern conservation biologists. The International Union for the Conservation of Nature IUCN has organized a global assortment of scientists and research principles of conservation biology pdf download across the planet to monitor the changing state of nature in an effort to tackle the extinction crisis.
Concerns for biodiversity loss covers principles of conservation biology pdf download broader conservation mandate that looks at ecological processes, such as migration, and a holistic examination of biodiversity at levels beyond the species, including genetic, population and ecosystem diversity. While the conservation status of species is employed extensively in conservation management, [75] some scientists highlight that it is the common species that are the primary source of exploitation and habitat alteration by humanity, principles of conservation biology pdf download.
Moreover, common species are often undervalued despite their role as the primary source of ecosystem services. While most in the community of conservation science "stress the importance" of sustaining biodiversity[79] there is debate on how to prioritize genes, species, principles of conservation biology pdf download, or ecosystems, which are all components of biodiversity e.
Bowen, While the predominant approach to date has been to focus efforts on endangered species by conserving biodiversity hotspotssome scientists e. They reason it is better to understand the significance of the ecological roles of species.
Biodiversity hotspots and coldspots are a way of recognizing that the spatial concentration of genes, species, and ecosystems is not uniformly distributed on the Earth's surface. For example, "[ Those arguing in favor of setting priorities for coldspots point out that there are other measures to consider beyond biodiversity.
They point out that emphasizing hotspots downplays the importance of the social and ecological connections to vast areas of the Earth's ecosystems where biomassnot biodiversity, reigns supreme.
