Wetland

A wetland is a land area that is saturated with water, either permanently or seasonally, such that it takes on the characteristics of a distinct ecosystem. The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique hydric soil. Wetlands play a number of roles in the environment, principally water purification, flood control, carbon sink and shoreline stability. Wetlands are also considered the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal life. Wetlands occur naturally on every continent except Antarctica, the largest including the Amazon River basin, the West Siberian Plain, and the Pantanal in South America. The water found in wetlands can be freshwater, brackish, or saltwater. The main wetland types include swamps, marshes, bogs, and fens; and sub-types include mangrove, carr, pocosin, and varzea.

The UN Millennium Ecosystem Assessment determined that environmental degradation is more prominent within wetland systems than any other ecosystem on Earth. International conservation efforts are being used in conjunction with the development of rapid assessment tools to inform people about wetland issues.

Lucas M. Miller

Lucas Miltiades Miller (some sources report his first name as Lucius) (September 15, 1824 – December 4, 1902) was an American merchant, attorney and politician who served as a U.S. Representative from Wisconsin.

Biography

Born in Livadia, Greece, Miller was left an orphan at the age of four, when he was adopted by J.P. Miller, an American who served as a colonel in the Greek Army during the Greek revolution. He accompanied his foster father upon his return to the United States and settled in Montpelier, Vermont in 1828. He attended the common schools and studied law, being admitted to the bar in 1845.

He began a law practice in Oshkosh, Wisconsin, in 1846, while also owning a general merchandise business with Edward Eastman, a fellow emigrant from Vermont. He also engaged in agricultural pursuits and served as colonel of militia in the Mexican–American War.

He was nominated for the Wisconsin State Senate's Fourth District in 1849 as the candidate of the "Union Democratic Party" (soon to join with the Free Soil Party) faction of the Wisconsin Democratic Party; but lost to John A. Eastman, the Regular Democrat or "Hunker" Democratic candidate.

State park

State parks or provincial parks are parks or other protected areas managed at the sub-national level within those nations which use "state" or "province" as a political subdivision. State parks are typically established by a state to preserve a location on account of its natural beauty, historic interest, or recreational potential. There are state parks under the administration of the government of each U.S. state, and of some states of Mexico. The term is also used in Australia, though the distinction between state and national parks there is different. The Canadian equivalent term is provincial park. Similar systems of local government maintained parks exist in other countries, but the terminology varies.

State parks are thus similar to national parks, but under state rather than federal administration. Similarly, local government entities below state level may maintain parks, e.g., regional parks or county parks. In general, state parks are smaller than national parks, with a few exceptions such as the Adirondack Park in New York and Anza-Borrego Desert State Park in California.

Blue crane

The blue crane (Anthropoides paradiseus), also known as the Stanley crane and the paradise crane, is the national bird of South Africa.

Description

The blue crane is a tall, ground-dwelling bird, but is fairly small by the standards of the crane family. It is 100–120 cm (3 ft 3 in–3 ft 11 in) tall, with a wingspan of 180–200 cm (5 ft 11 in–6 ft 7 in) and weighs 3.6–6.2 kg (7.9–13.7 lb). Among standard measurements, the wing chord measures 51.4–59 cm (20.2–23.2 in), the exposed culmen measures 8–10 cm (3.1–3.9 in) and the tarsus measures 20.5–25.2 cm (8.1–9.9 in). This crane is pale blue-gray in colour becoming darker on the upper head, neck and nape. From the crown to the lores, the plumage is distinctly lighter, sometimes whitish. The bill is ochre to greyish, with a pink tinge. The long wingtip feathers which trail to the ground. The primaries are black to slate grey, with dark coverts and blackish on the secondaries. Unlike most cranes, it has a relatively large head and a proportionately thin neck. Juveniles are similar but slightly lighter, with tawny coloration on the head, and no long wing plumes.

Bill Nye

William Sanford "Bill" Nye (born November 27, 1955), popularly known as Bill Nye the Science Guy, is an American science educator, comedian, television presenter, actor, writer, scientist, and former mechanical engineer, best known as the host of the Disney/PBS children's science show Bill Nye the Science Guy (1993–1998) and for his many subsequent appearances in popular media as a science educator.

Early life and education

Nye was born on November 27, 1955, in Washington, D.C., to Jacqueline (née Jenkins; 1921–2000), a codebreaker during World War II, and Edwin Darby "Ned" Nye (1917–1997), also a World War II veteran, whose experience without electricity in a Japanese prisoner-of-war camp led him to become a sundial enthusiast. His maternal grandmother was French, from Dancevoir.

After attending Lafayette Elementary and Alice Deal Junior High in the city, he was accepted to the private Sidwell Friends School on a partial scholarship and graduated in 1973. He studied mechanical engineering at Cornell University (where he took an astronomy class taught by Carl Sagan) and graduated with a B.S. in mechanical engineering in 1977. Nye occasionally returns to Cornell as a guest-lecturer of introductory-level astronomy and human ecology classes.
