Conservation Biology As A Profession

MESELSON and STAHL – Evidence of semi-conservation replication for A-level Biology. DNA REPLICATION

The Society 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 philosophy, law, economics, humanities, arts, anthropology, and education. Within biology, conservation genetics and evolution are immense fields unto themselves, but these disciplines are of prime importance to the practice and profession of conservation biology.

Conservationists introduce bias when they support policies using qualitative description, such as habitat degradation, or healthyecosystems. Conservation biologists advocate for reasoned and sensible management of natural resources and do so with a disclosed combination of science, reason, logic, and values in their conservation management plans. This sort of advocacy is similar to the medical profession advocating for healthy lifestyle options, both are beneficial to human well-being yet remain scientific in their approach.

In Summary: Conservation Biology And Biodiversity

Biodiversity exists at multiple levels of organization and is measured in different ways depending on the goals of those taking the measurements. These measurements include numbers of species, genetic diversity, chemical diversity, and ecosystem diversity. The number of described species is estimated to be 1.5 million with about 17,000 new species being described each year. Estimates for the total number of species on Earth vary but are on the order of 10 million. Biodiversity is negatively correlated with latitude for most taxa, meaning that biodiversity is higher in the tropics. The mechanism for this pattern is not known with certainty, but several plausible hypotheses have been advanced.

Five mass extinctions with losses of more than 50 percent of extant species are observable in the fossil record. Biodiversity recovery times after mass extinctions vary, but have been up to 30 million years. Recent extinctions are recorded in written history and are the basis for one method of estimating contemporary extinction rates. The other method uses measures of habitat loss and species-area relationships. Estimates of contemporary extinction rates vary, but some rates are as high as 500 times the background rate, as determined from the fossil record, and are predicted to rise.

Biodiversity may provide important psychological benefits to humans. Additionally, there are moral arguments for the maintenance of biodiversity.

Conservation In Human Altered Landscapes

The solutions to the problems facing conservation biologists will not be found solely by adopting new paradigms such as ecosystem management or sustainable development. Blending the theories developed in conservation biology with these new paradigms will potentially allow for better management of species within their landscapes. However, conservation biologists will not automatically find the tools that they need from other disciplines. These new paradigms are currently struggling to develop tools that will be able to take theories and make them applicable to, for example, forest certification. Furthermore, conservation biologists have not developed structures similar to ecosystem management that would allow them to develop an adaptive management model . Without such a process or framework to effectively link policy to science and management, it is difficult to integrate scientific findings into management itself. As stated by Gordon in 1999, Often, policy is made with old science, while interest groups confront the manager of public resources with new science. One could speculate that old science is used because the tools have not been developed to implement or make the new science work at the ground level or in policy.

Major Advising Page Conservation Biology

Students majoring in Conservation Biology are highly encouraged to complement their coursework with out-of-classroom experiences such as study abroad. Studying abroad exposes the student to a wide array of opportunities that will strengthen their understanding of conservation issues throughout the world. In addition, the international experience gained from studying abroad is highly attractive to potential graduate programs and employers.

Fortunately, the flexibility of the Conservation Biology major makes study abroad a feasible and appealing option for students. Conservation Biology students can take advantage of this opportunity during nearly any semester if they plan well and early. The information included below is intended to help students make study abroad a reality as they meet with advisors and plan their experience.

Conservation Biology Supports All But One Of The Following Practices

Why Do Ecologists Study Habitats

The question is incomplete. Following are the options:

A) the preservation of natural habitats

B) the protection of endangered species

C) the management of available natural resources

D) the introduction of alien species to an area outside their normal range

Answer:

The practice which conservation biology doesn’t support is D) the introduction of alien species to an area outside their normal range

Explanation:

Conservation biology can be described as a branch of biology in which humans try their best to protect the biodiversity present on Earth. The management of species, their habitat, their ecosystems and natural resources all come under this field. Strategies to protect endangered species and increase their number is also the concern of conservation biology.

However, conservation biology has nothing to do aliens, hence option D is not a part of conservation biology.

Explain Why Conservation Biology And Biodiversity Are Important

In the 1980s, biologists working in Lake Victoria in Africa discovered one of the most extraordinary products of evolution on the planet. Located in the Great Rift Valley, Lake Victoria is a large lake about 68,900 km2 in area . Biologists were studying species of a family of fish called cichlids. They found that as they sampled for fish in different locations of the lake, they never stopped finding new species, and they identified nearly 500 evolved types of cichlids. But while studying these variations, they quickly discovered that the invasive Nile Perch was destroying the lakes cichlid population, bringing hundreds of cichlid species to extinction with devastating rapidity.

Figure 1. Lake Victoria in Africa, shown in this satellite image, was the site of one of the most extraordinary evolutionary findings on the planet, as well as a casualty of devastating biodiversity loss.

Prospective Conservation Biology Students

Current and potential Conservation Biology students should be aware of course requirements and expectations when planning for study abroad. In particular, students are strongly encouraged to complete foundational coursework in math and chemistry, and the intro biology sequence during their first and second years.

You can study abroad at any point during your time at UW-Madison, but most students choose to study abroad during their junior or senior year. To gain background information about study abroad and the various programs available, attend the Study Abroad Fair on campus, visit the Program Search database on the International Academic Programs website, and/or schedule a meeting with an advisor at IAP. Once you have identified some potential programs, meet with the Conservation Biology advisor for consultation and planning. The earlier students begin this process and start planning in earnest, the better, as this will open up more possibilities.

Uncertainties In The Study Of Biodiversity

Practitioners have labeled conservation biology a crisis science, meaning that in a context of great uncertainty, as with certain branches of medicine, the risks of inaction are greater than those of action. The question, what proportion of the worlds biodiversity can be lost before the planets human life-support systems collapse, cannot be answered with certainty given the current state of scientific knowledge. Waiting for that question to be answered with scientific certainty is to risk, quite literally, the end of the world as we know it. Generally, it is this sort of unanswered empirical, scientific question that conservation biologists refer to when writing of uncertainty. But there are also more fundamental ontological and ideological sources of uncertainty in understanding biodiversity. These include questions regarding how species are inventoried and classified, how well scientific models reflect reality, and the anthropogenic sources of biodiversity.

What Is The Current Focus On Conservation Biologists Worldwide

Biology For NEET & AIIMS | Biodiversity and Conservation – Types of Diversities

There are multiple focuses but many relate to habitat destruction and loss.

Explanation:

Conservation biologists focus on a multitude of topics depending on the ecosystem they study and their individual interests and resources. Many are focusing on issues related to habitat loss and destruction, as this is the leading cause of species decline worldwide.

The reasons behind this habitat loss can vary immensely: climate change, conversion of land from natural area to agriculture, increasing urbanization, exploitation of the land for natural resources such as oil and timber, loss of suitable aquatic habitat due to pollution from industry, decreased streamflow due to shrinking glacial sources of input, etc.

No matter the reason, habitat loss remains the primary factor behind the decline and extinction of most species at present.

What Is Wildlife And Conservation Biology

The Wildlife and Conservation Biology program provides students with the multi-disciplinary background necessary to manage and conserve wildlife and their habitats against the backdrop of human population growth, development and climate change. Students in this degree program develop a broad foundation in the natural sciences and learn to manage a wide range of species.

The Impact Of Agriculture

Habitat loss from agricultural expansion is arguably the biggest current challenge to biodiversity conservation in Africa . At the root of this problem is the need to supply food and other resources to a growing human population. Exacerbating the situation, much of Sub-Saharan Africas arable land has already been degraded to such a degree that it cannot sustain viable food production anymore . Most of these losses are not due to natural factors, but to poor land management practices, such as overgrazing, continual ploughing of fields, and heavy use of fertilisers. These practices release nitrogen, carbon, and oxygen into the atmosphere and compromise the soils ability to hold water, leading to erosion, soil salinisation, desertification, and even climate change . This not only lead to collapsing ecosystem services, but also increased competition for space as even more land must be converted for agriculture, and to accommodate people and their activities. Such land conflicts are only going to become worse with climate change .

Biodiversity-friendly farming practices can also produce economic benefits and so, many government programmes are now promoting sustainable agricultural intensification.

If the discipline of conservation biology was founded with an emphasis on intrinsic value of biodiversity, today’s conservation has become focused on ecosystem services as the primary rationale to protect nature. ES are the benefits that nature provides to society, which include the provision of goods, raw materials, and energy feedstocks regulation of life support systems and cultural benefits of human relationships with natural environments . An assessment of ES can be used to measure the many ways in which ecosystems benefit people, can highlight how anthropogenic impacts on ecosystems may feedback onto various aspects of human well-being, and provide a richer basis for incorporating complex humannature relationships in policy and decision-making.

Biodiversity is defined at three levels: genetic diversity species diversity and ecosystem diversity . Biodiversity is invaluable to the process of evolution since it represents the pool of resources from which evolution can select it is the key to adaptation to changes, since the greater the biodiversity, the more resilient an ecosystem will be following natural disasters or human intrusions. This focus area provides a background in the biological principles that influence the diversity of life, especially those that create and those that reduce diversity.

What Is Conservation Biology

Whether or not there is a single thing that conservation biology as adiscipline purports to conserve, there are philosophical questions tobe raised regarding the discipline itself. Specifically, is it acollection of theories or models or something else? To explore thisquestion, we will consider central examples of conservationbiologys practice. We can then turn to how best to understandwhat conservation biology is. But first, it useful to consider whattheories and models are.

Models are a type of representation that involve abstractions andidealizations .Abstraction in a representation involves not including all of theproperties of the thing represented and idealization involvesdistorting those features that are represented. That is, models deleteand distort. Another important feature of models is that theyindirectly represent the world. According to many philosophers ofscience, models describe mathematical or abstract objects, and theseobjects are more or less similar to particular objects in the world, but see Hughes ). Theories assets of laws represent the world directly because their propositionalcontent is about natural systems. There are a number of differenttypes of models used which include physical, scale, computational, andmathematical models.

Conservation biologists use models all the time in almost every facetof their work. So we now consider several case studies of conservationbiology.

Broad Speculation On The Future Of Conservation Biology

Conservation biology has become a burgeoning discipline since it originated in the early 1980s. Theories from the fields of island biogeography, genetics, demography, and population ecology have been broadly applied to the design and management of reserves, captive breeding programs, and the classification of endangered species. Since 1980 we have witnessed the rapid expansion of a professional society and the emergence of active graduate programs.

Nonetheless, the course of development of the discipline has not altogether been smooth sailing lack of adequate funding remains a critical problem. The financial and institutional supports for conservation biology, in both its research and educational roles, need to be strengthened . Furthermore, while some advances have been made in the realm of interdisciplinary cooperation and communication between scientists and managers, significant progress is necessary before the original goals of conservation biology can be met.

What Is Conservation Management Biology

Conservation management may include the preservation, protection, or restoration of species populations, habitats, or ecosystems. These actions can help to reduce species extinctions, the erosion of biotic interactions and environmental degradation. Biological conservation may occur in situ or ex situ.

Smart Development Outside Conservation Areas

Infrastructure development poses a significant and escalating challenge to biodiversity conservation efforts. Dams and fences impede wildlife dispersal and migrations , power distribution lines and high-rise buildings pose a collision hazard to birds and bats , and city expansions compete with biodiversity for space. Expanding road networks are particularly harmful because roads open new areas for deforestation, urban sprawl, agricultural expansion, and unsustainable hunting . A recent review found that 75 % of Sub-Saharan Africas development corridorslarge-scale infrastructure developments meant to stimulate economic growthwould cut through sparsely-populated and low-quality agricultural, range, and forest lands . These developments not only threaten the wildlife living within those areas , but also the carbon-sequestering potential of large swathes of tropical forests . Most alarming, the corridors planners have shown very little regard for existing biodiversity conservation efforts, given that the proposed transportation network cuts directly through 408 existing protected areas, which includes 69 national parks, biosphere reserves, World Heritage Sites, and Ramsar wetlands . In contrast, only five of the 33 planned and active development corridors would cross areas of low conservation priority and with promising agricultural potential .

Conservation Biology Is Still Evolving

As a distinct scientific field, conservation biology is an integrated, multidisciplinary subject that developed in response to the challenge of preserving populations, species, ecosystems, and biological interactions. The main aim of conservation biology is to ensure the long-term preservation of biodiversity. To achieve its aim, conservation biology has set three goals:

  • To document Earthâs biological diversity.
  • To investigate how humans influence species, evolution, and ecosystem processes.
  • To investigate practical approaches to protect and restore biological communities, maintain genetic diversity, and prevent the extinction of species.

The first two goals describe typical scientific research investigating objective facts. The third goal, however, is a part of what makes conservation biology a normative discipline that is, conservation biology incorporates human values, not just facts, to understand and achieve its value-laden goals . In this sense, conservation biology is related to environmentalism, in which people aim to protect the natural environment for its own sake . However, conservation biology is at its core a scientific discipline it is founded on scientific principles. This is not to say you must be a scientist to practice conservation biology there are many people who are not scientists who apply the principles of conservation biology in their professional and personal lives.
