Ecology

Ecology (from Greek: οἶκος, "house", or "environment"; -λογία, "study of") is the scientific analysis and study of interactions among organisms and their environment. It is an interdisciplinary field that includes biology, geography and Earth science. Ecology includes the study of interactions organisms have with each other, other organisms, and with abiotic components of their environment. Topics of interest to ecologists include the diversity, distribution, amount (biomass), and number (population) of particular organisms, as well as cooperation and competition between organisms, both within and among ecosystems. Ecosystems are composed of dynamically interacting parts including organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primary production, pedogenesis, nutrient cycling, and various niche construction activities, regulate the flux of energy and matter through an environment. These processes are sustained by organisms with specific life history traits, and the variety of organisms is called biodiversity. Biodiversity, which refers to the varieties of species, genes, and ecosystems, enhances certain ecosystem services.

Eco (video game)

Eco is a wire-frame 3D evolution life simulation game developed by Denton Designs for the Amiga and Atari ST. It was released in 1988 and published by Ocean Software.

The player initially uses mouse or joystick to control an insect, which must avoid predators, find some food, and then find another insect of the same species and mate with it. The player can then unlock one of several "genes", altering the value of which changes their creature. Some changes are only cosmetic and leave the creature in the same species; others can, for instance, make the initial insect a new species with wings and capable of flight. After unlocking multiple genes the player can become a fast dog-like quadruped, a bird, a scorpion or a humanoid. The game does not end until the player starves, is killed by another creature, or deliberately "evolves" into a plant.

Commerce

Commerce is the activity of buying and selling of goods and services, especially on a large scale or quantity. The system includes legal, economic, political, social, cultural and technological systems that are in operation in any country or internationally. Thus, commerce is a system or an environment that affects the business prospects of economies. It can also be defined as a component of business which includes all activities, functions and institutions involved in transferring goods from producers to consumers.

History

Some commentators trace the origins of commerce to the very start of communication in prehistoric times. Apart from traditional self-sufficiency, trading became a principal facility of prehistoric people, who bartered what they had for goods and services from each other. Historian Peter Watson dates the history of long-distance commerce from circa 150,000 years ago.

In historic times, the introduction of currency as a standardized money, facilitated a wider exchange of goods and services. Numismatists have collections of these monetary tokens, which include coins from some Ancient World large-scale societies, although initial usage involved unmarked lumps of precious metal.

Commerce (river)

The river Bolbec or Commerce is one of the rivers that flow from the plateau of the southern Pays de Caux in the Seine-Maritime département of Haute-Normandie into the Seine.
The river rises at Bolbec and passes Gruchet-le-Valasse, where its name changes to the Commerce. It then passes through Lillebonne and joins the Seine at Notre-Dame-de-Gravenchon.

Economy

The river hosted many watermills that powered machinery to process both cotton and flax. The area became so prosperous it was named the Golden Valley.

Notes

Commerce, Texas

Commerce is a Texas city located in Hunt County, Texas, United States, situated on the eastern edge of North Texas, in the heart of the Texas Blackland Prairies, and the northeastern part of the Dallas/Fort Worth Metroplex. The town is 60 miles (97 km) from Dallas, Texas, and 45 miles south of the Texas/Oklahoma border. Commerce is the second largest city in Hunt County with a population of 8,599 residents as of 2014. The rural city is home to Texas A&M University–Commerce, a major 4-year University of over 12,000 students that has been in the town since 1894. Commerce is one of the smallest college towns in Texas.

History

The town of Commerce was formed when two merchants named William Jernigan and Josiah Jackson established a trading post and mercantile store located where the present day downtown area is. The rural area just to the northeast of the area was an open prairie area originally known as Cow Hill. The town was established in 1872 and named Commerce due to the thriving economic activity, and cotton fields and ideal farm and ranch lands between the Middle and South Sulphur rivers on the rich, black gumbo prairie in northeast Hunt County. The town incorporated in 1885. Two years later, a railroad was built through Commerce to transport merchandise from Fort Worth, and nine years later, William L. Mayo, a college educator, moved East Texas Normal College from the Northeast Texas town of Cooper to Commerce after the original school in Cooper was destroyed in a fire. Mayo continued as president of the college, now known as Texas A&M University–Commerce, until his death in 1917 and is buried on the campus grounds.
