Ecosystems Ecosystems The plants and animals that are found in a particular location are referred to as an ecosystem. These plants and animals depend on each other to survive. In a delicate balance, these lifeforms help to sustain one another in regular patterns. Disruptions to an ecosystem can be disastrous to all organisms within the ecosystem. As an example, consider what happens when a new plant or animal is introduced into an ecosystem where it did not before exist. Throughout the history of the Earth, the delicate balance found within ecosystems has been disrupted by natural disasters such as fires, floods, storms, volcano eruptions, and so forth.
Internet E-MAIL (ELECTRONIC MAIL) Every person has an e-mail address which takes the form of his or her name, the @ (at), and a domain name, such as jsmith@mammoth.com. The domain name contains the name of the person’s service provider or organization or provider and often its country, each separated by a dot. The domain name mammoth.com stands for Mammoth Corporation, which is a commercial organization (com). E-mail offers you more than a quick and easy way to send people written messages.

Consumer-resource systems Figure 1. Consumer categories based on material eaten (plant: green shades are live, brown shades are dead; animal: red shades are live, purple shades are dead; or particulate: grey shades) and feeding strategy (gatherer: lighter shade of each color; miner: darker shade of each color). Consumer-resource interactions are the core motif of ecological food chains or food webs,[1] and are an umbrella term for a variety of more specialized types of biological species interactions including prey-predator (see predation), host-parasite (see parasitism), plant-herbivore and victim-exploiter systems. Classification of consumer types[edit] A fully inclusive nomenclature is shown in Figure 1. Words for miners are of Greek etymology and words for gatherers are of Latin etymology.

Internet U.S. Army soldiers "surfing the Internet" at Forward Operating Base Yusifiyah, Iraq The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to link several billion devices worldwide. It is a network of networks[1] that consists of millions of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), the infrastructure to support email, and peer-to-peer networks for file sharing and telephony. Most traditional communications media, including telephony and television, are being reshaped or redefined by the Internet, giving birth to new services such as voice over Internet Protocol (VoIP) and Internet Protocol television (IPTV).

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. Densham, who dropped out of high school at 15, recently wrote a how-to book on screenwriting called "Riding the Alligator" (Michael Wiese Productions, $24.95). 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? A: It is important to embrace creativity for personal growth, not for an end result. Q: Can Facebook provide a real creative outlet?
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.

Smithsonian Civil War Studies: Article - A Pathway To Freedom: Maryland's Underground Railroad A Pathway To Freedom: Maryland's Underground Railroad The Smithsonian Associates Civil War E-Mail Newsletter, Volume 8, Number 6 Because of its location just below the Mason-Dixon Line, Maryland occupied a pivotal place in a secret network of trails and sanctuaries known as the Underground Railroad. This was the last "station" that separated North from South - and freedom from bondage - for countless slaves secreted across back roads and waterways. Harriet Tubman completed the daring journey repeatedly during the 1800s, having escaped from a plantation in Dorchester County to become the railroad's most famous "conductor." In and around Cambridge, visitors can see the small church where Tubman worshipped, as well as a humble marker noting her approximate birthplace. Farther south, the Hollywood-based Sotterley Plantation has a rare slave cabin and outbuildings beside the Patuxent River.

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. Until now, we have neglected a particular group of networks that are more fundamental and important than any of those created by people: ecosystems. 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." back to top Networks in nature are constantly changing. Next: Resources
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
