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

21st Century Libraries The internet has given students an incredibly vast world of up-to-the-minute resources, including nearly limitless outlets for research and investigation. But many students turn immediately to the untamed internet when faced with a research assignment, often overlooking the value in a virtual library solution. Virtual library collections, or databases, give students access to trusted content and research tools with links to authoritative information that has been vetted by subject-matter experts. Today’s 21st-century school libraries make use of virtual collections while also giving students ample opportunities for enhancing their digital literacy, research, and collaboration skills which are essential in a globally connected world. With the generous support of Questia School, the editors of eSchool News have compiled this collection of stories from our archives, along with other relevant information from around the web, to help you transform your school libraries for the 21st century.

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.

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.
