Are There Keystone Species in Information Ecologies That Might Affect Knowledge Management Processes

Words: 1504 Length: 5 Pages Document Type: Essay Paper #: 61951133

Keystone Species

In mid-1800's, telegraphy was invented. This invention was revolutionary because it decreased all the hurdles in communication of information. This type of invention or any innovations that connects two or more people and acts as a survival tool for a particular group i.e. ethnic or technological group is known as Keystone specie. Even though Specie is a term mostly used for living organisms, here in a larger context keystone specie is referred to as "a system of people, practices, values, and technologies" that is essential for the survival of anything. (Johnson, 2010)

The keystone species concept has been a mainstay of the ecological and conservation biology literature since its introduction by UW zoology professor Robert T. Paine in 1969. His seminal paper extended the conclusions of a field experiment published three years earlier. The research resulting in the keystone species concept was done on Makah Tribal lands on…… [Read More]

Georgia's Environment

The ecologies and environment: From the Atlantic Ocean to the Appalachian Plateau, Georgia is a very diverse state in terms of its ecology and geography. The state is the largest east of the Mississippi River, and its elevation ranges from sea level to more than 4,700 feet. The New Georgia Encyclopedia reports that there are five distinct "physiographic provinces" in Georgia: the Blue Ridge, the Piedmont, the Appalachian Plateau, the Ridge and Valley, and the Atlantic Coastal Plain. In the extreme northwestern part of the state, the Appalachian Plateau has historically been a region where mining has taken place. That Appalachian Plateau actually connects some parts of Georgia with Tennessee and eastern Alabama.

The cities in Georgia are located in the Piedmont region, which is highly industrialized, and includes the sprawling megalopolis of Atlanta. The "fall line" in Georgia is the place where the coastal plain meets the…… [Read More]

Indeed the Ethiopian Wolf, otherwise known as canine simensis, is currently in endangered status according to the IUCN. This paper will discuss the ecological factors, animal behavior factors and the overall current status of the Ethiopian Wolf. While the Ethiopian Wolf is not yet extinct, it is certainly endangered at this time.

Questions Answered

When it comes to the ecology and behavior relating to the Ethiopian Wolf, there are a few factors that were described by Tallents et al. (2012) treatise on the subject. The author gave a few points in her work. First, she notes that human encroachment on Ethiopian Wolf territory increases a rather large amount for each single human that enters it. Indeed, she notes that each person leads to 1.18 kilometers less room for the Ethiopian Wolf…… [Read More]

Hawkens 1992 Tells Us That

Words: 790 Length: 2 Pages Document Type: Essay Paper #: 600651

Part 2.

Hawkens (1992) states that corporations can function in whichever way they wish. hey are like an organism that can function by destructing the environment, but, made with interchangeable parts, they can be also useful to the environment if taught how. Rather, therefore, then demanding that corporations cease to exist, we should encourage them to reorganize their parts and become more socially responsible. he way to do this is by adopting some of the following principles:

Firstly, by reducing absolute consumption of energy and natural resources in the North by 80% during the next century. Businesses can do this in a painless way.

he next step, Hawkens recommends is to provide secure, stable, and meaningful employment for people everywhere. Businesses need employees. Gainfully employing helps the world become a happier place.

Businesses need to be self-actuating. What this means is that we want to flourish and prosper and we…… [Read More]

This last part of Hawken's book is generally prescriptive giving us ways of how we can make businesses more socially responsible. Realizing that we are part of an integrated whole, makes us realize our responsibility in helping businesses practice the concept of industrial ecology.

Wildlife Ecology and Conservation

There should be a balance between books and journal/periodicals dealing with the subject of Wildlife, Ecology and Conservation that appeal to an interested audience, but in different styles. These are divided into: 1) Scholarly or Academic Journals, 2) Periodicals, ) Books.

Ecology and Society -- This journal is a broader topic journal that deals with integrative science, ecology and sustainability. It focuses on land and water ecology, opportunities for sustainable development, and exploration of multi-disciplinary opportunities in the sciences surrounding fish, wildlife, and flora. This would be useful to the center because it provides a wider background of material, while still remaining scientific.

The Delta is also a habitat for many species of fish, birds, mammals, and plants, and it supports agricultural and recreational activities while also being the focal point for water distribution throughout the State.

The development of the Delta as it exists today started in late 1850 when the Swamp and Overflow Land Act transferred ownership of all swamp and overflow land, including Delta marshes, from the federal government to the State of California. In 1861, the State Legislature created the Board of Swamp and Overflowed Land Commissioners to manage reclamation projects, and in 1866, the authority of the Board was transferred to county boards of supervisors. The Delta now covers 738,000 acres interlaced with hundreds of miles of waterways, with much of the land below sea level, relying on more than 1,000 miles of levees for protection against flooding. 20

History of Landscape Patterns

Words: 643 Length: 2 Pages Document Type: Essay Paper #: 80446079

History Of Landscape Patterns

Although historical ecology remains a relatively recent conceptualization, it provides a useful framework in which to understand the relationship between the historic uses to which terrain has been placed and its modern applications (Balee, 1999). The research to date in this area has focused in part on the history of landscape patterns. For instance, Balee reports that, "The concept of landscape, above all, seems paramount in historical ecology. These usages, when comprehended technically, facilitate a more holistic (and therefore more accurate and empirically sound) analysis of human ecology" (1999, p. 1). This point is also made by Swetnam, Allen, and Betancourt (1999) who discuss historical ecology and the importance of knowing the history of a landscape when making contemporary management decisions concerning new applications. In this regard, Swetnam and his associates note that, "Applied historical ecology is the use of historical knowledge in the management of…… [Read More]

This entity follows the California Clean Air Act and the Federal Clean Air Act so that it is responsible for air monitoring, permitting, enforcement, long-range air quality planning, regulatory development, and education and public information activities with regard to air pollution.

A more recent concern has developed as the first cruise ship to enter Monterey ay since 1966 caused environmental groups to demand increased protection for marine sanctuaries and to increase regulation of the cruise ship industry. The water around Monterey ay has also been affected by sewage spills at local beaches, leading to viral and bacterial contamination. In 2000, four Monterey County beaches were closed because of sewage spills, and twenty-five warning advisories were issued. In 2001, there was one beach closure and eleven advisories. It has also been found that there is inadequate storm pipe maintenance in cities on the Monterey peninsula.

" The report claims that the soft shell clam and oyster fisheries "have collapsed" and the commercial harvest of striped bass is now restricted to protect the survival of that species (Virginia Environment). In the last 30 years, according to the Executive Summary of the Arlington "Urban Forest Master Plan" (UFMP) Arlington County has lost "a significant amount of acreage with heavy tree cover"; this has had "a dramatic effect on the overall canopy coverage." Of the 16,500 acres of forests more than 3,000 acres have been "converted from heavy tree cover of over 50% to low tree cover of less than 20%" (UFMP).

How might global warming affect local ecosystems in and around Arlington? The rising level of the Atlantic Ocean is considered a major risk in terms of global warming. Already the rising waters have submerged several islands in the Chesapeake Bay. "The region's coastal habitats and the…… [Read More]

Water as Landscape

Words: 581 Length: 2 Pages Document Type: Essay Paper #: 22199453

Landscape ecology conventionally has been constrained to the knowledge of earthly methods; nevertheless, the inquiries and approaches describing the science are similarly linked for oceanic and seaside structures. The author points out that the shared relationship among longitudinal design, and ecological processes and the overarching sense of proportion on this relationship was being explored in some marine, and coastal settings as the general rule of landscape ecology were changing throughout the last 20 years of the last century. It was clear that the author intent of this article was to highpoint a study regarding changing the tools of landscape ecology to answer questions that are ecological.

The article stressed that there was a risky strategy for many organisms that inhabited spatially extensive marine landscapes which were the larval dispersal. It was fascinating to learn that a lot of the present work has put a lot of emphasis on the biophysics…… [Read More]

Landscape Ecology:

eutral Landscape Models

The neutral landscape model is part of the study of landscape level patterns and processes. These patterns and processes are said to have suffered from lack of statistical design and replication.

The reason for this is because it is difficult to conduct experiments on such a large scale. According to the study referenced here, both the spatial extent as well as the inherent heterogeneity of landscape mosaics makes it a challenge to actually find comparison landscapes that can broaden the lack of such research.

The study also states that neutral landscape models (LMs) represent null hypotheses at the landscape scale. LMs are actually defined as a "special class of models" and are stated to be useful in a "discipline where replication and manipulation are logistically problematic."

The objective of utilizing LMs is in order to provide some sort of a benchmark, and to utilize…… [Read More]

Influence of Scale

Words: 666 Length: 2 Pages Document Type: Essay Paper #: 34193997

Scales are the topographical instruments used to divide objects or processes into levels of organization of space or time and to distinguish objects within, for instance, a biotic hierarchy. Scale is designed by using grain and extent. Grain refers to the spatial resolution within a particular data set e.g. The cell size for gridded maps whilst extant refers to the overall size of the map used to demonstrate temporarily and dimension of characteristic. A population, pattern, or process that is scale-dependent implies that the object under consideration is correlated with the scale, i.e. changes with the grain or extent of measurement. "Large scale' refers to extremely fine resolution (i.e. precision of measurement), whereas 'small scale' refers to the opposite.

Scales are both advantageous and disadvantageous when applied to ecology and to environmental concerns. On the one hand, ecological variables demonstrate numerous and multiple change and knowing where one environment or…… [Read More]
