Ecosystem History and development The term "ecosystem" was introduced by Arthur Roy Clapham in early 1930s and became more widely known via the works of Arthur Tansley, a British ecologist.[fn 1][10] Tansley devised the concept to draw attention to the importance of transfers of materials between organisms and their environment.[11] He later refined the term, describing it as "The whole system, ... including not only the organism-complex, but also the whole complex of physical factors forming what we call the environment".[12] Tansley regarded ecosystems not simply as natural units, but as mental isolates.[12] Tansley later[13] defined the spatial extent of ecosystems using the term ecotope. G. Ecosystem processes Ecosystems are controlled both by external and internal factors. Unlike external factors, internal factors in ecosystems not only control ecosystem processes, but are also controlled by them. Primary production Energy flow Left: Energy flow diagram of a frog.

Smithsonian Institution Marine Science Network The Smithsonian Marine Science Network (MSN) was established in 1998. The MSN operates a unique array of laboratories and research vessels that spans the latitudinal gradient of the western Atlantic (Chesapeake Bay, Indian River Lagoon, Mesoamerican Barrier Reef and Panamanian Coast) and crosses the isthmus of Panama. The Network is dedicated to understanding the rich biodiversity and complex ecosystem dynamics that sustain coastal processes and productivity. MSN scientists study evolutionary, ecological, and environmental change in the ocean’s coastal zones, increasing scientific knowledge of these environments, and improving society’s appreciation of the ocean’s effect on our lives. Coastal environments are of immense economic and environmental importance and comprise 95% of the ocean’s fisheries. Overview of Marine Science Network Smithsonian Institution / Copyright / Privacy

Themeefy | Curate. Learn. Teach Teaching In The Cloud - Cognoscenti - WBUR Google’s online word processor has transformed the way teachers support students through the writing process. (alamosbasement/flickr) Any experienced English teacher knows the drill: on the dreaded due date, students bring printed copies of their essays to class, where we collect them, take them home, jot inscrutable comments in the margins, bring them back to class, return them, and then watch students promptly toss them in the recycling bin on the way out of the room. The whole cycle borders on farce. Students pretend to spend many hours writing their papers, teachers pretend to spend many hours grading them, and we all pretend like repeating this process over and over again leads to something we in education like to call “student growth.” But teachers can finally put an end to this exercise in futility, thanks to an unlikely hero sometimes condemned for its unrelenting pursuit of profit at the expense of the public good…Google.

Mathematics Illuminated | Unit 11 | 11.6 Ecosystems A food chain or food web is a graphic way of representing predator-prey and symbiotic relationships that exist in ecosystems. For most of this unit we have been focusing mainly on physical, human-made networks, such as our power grid, the Internet, and the nation's highway system. We have also looked briefly at intangible networks, such as webs of social connections. One common aspect of ecosystems is the food chain. A food chain provides a convenient way of obtaining a rough approximation of what happens in an ecosystem. Item 2919 /Neo Martinez, UNITED KINGDOM TROPHIC WEB (2005). Item 2920 / Neo Martinez, CARIBBEAN REEF TROPHIC WEB: IMAGE 1 (2005). Food webs are examples of directed graphs, because certain relationships are "one-way streets." Alternatively, remoras are fish that tend to attach themselves to sharks and feed off of scraps, bacteria, and feces. back to top Networks in nature are constantly changing. At each step in a food chain or web, a certain amount of energy is lost.

Why Records Management? | PRISM Information has always been an organization’s central resource. Without it, the modern organization simply could not function. Business records are operational—and sometimes strategic—assets. They have economic, legal, fiscal, risk-management, and competitive values. Narratives about such records management problems form the backbone of the field’s experience with organizations that lack records management. The creation, storage, retrieval, use, and destruction (or permanent archival retention) of information of all types and in all media is an increasingly difficult challenge for business and government organizations. Records are central to the work of all organized entities. Records management—also called “records and information management” or “recorded information management” (RIM)—is the systematic application of management principles—chiefly control—to the recorded information needed and used in the normal course of an organization’s business. Are Records Really Valuable? A. B.

What is Social Network Theory | LoveToKnow The question "what is social network theory?" is a misleading one. Technically, every interaction between more than two sources becomes a sort of social network - which is why social network analysis software can be used for everything from business organizations to contagious disease control. However, in recent years, with the development of Internet phenomena such as Facebook, social network theory (or SNT, as it is abbreviated) has become more and more focused on the many ways that people interrelate and communicate via the various social networking platforms. So What is Social Network Theory for the Internet? Basically there are two elements in any social network, online or offline: nodes and ties. The fact that these kinds of ties can vary in intensity and importance is just one of the many variables that can factor into social network theory.

Creative writing and kids: How to encourage it - chicagotribune.com June 14, 2011|By Wendy Donahue, Tribune Newspapers Parents nowadays worry more about the creative writing their kids do on Facebook than the kind in English assignments. But even for 140-character Tweets, encouraging children to put ideas into words is as vital as ever, says Pen Densham, screenwriter of films such as "Robin Hood: Prince of Thieves" and a teacher at the University of Southern California. He shares his views on the role creative writing can play for children today. Q: Is creative writing an endangered skill in this tech age? A: No. Q: How can parents encourage creative writing in their children? A: Each kid is like an uncut diamond. Q: Why should adults encourage creative writing?
