The North America Portal

North America is a continent in the Northern and Western Hemispheres. North America is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. The region includes the Bahamas, Bermuda, Canada, the Caribbean, Central America, Clipperton Island, Greenland, Mexico, Saint Pierre and Miquelon, the Turks and Caicos Islands, and the United States.

North America covers an area of about 24,709,000 square kilometres (9,540,000 square miles), representing approximately 16.5% of the Earth's land area and 4.8% of its total surface area. It is the third-largest continent by size after Asia and Africa, and the fourth-largest continent by population after Asia, Africa, and Europe. As of 2021, North America's population was estimated as over 592 million people in 23 independent states, or about 7.5% of the world's population. In human geography, the terms "North America" and "North American" can refer to Canada, the United States, Mexico, and Greenland or, alternatively, Canada, Greenland and the US (Mexico being classified as part of Latin America) or simply Canada and the US (Greenland being classified as either Arctic or European (due to its political status as a part of Denmark) and Mexico classified as Latin American).

It is unknown with certainty how and when first human populations first reached North America. People were known to live in the Americas at least 20,000 years ago, but various evidence points to possibly earlier dates. The Paleo-Indian period in North America followed the Last Glacial Period, and lasted until about 10,000 years ago when the Archaic period began. The classic stage followed the Archaic period, and lasted from approximately the 6th to 13th centuries. Beginning in 1000 AD, the Norse were the first Europeans to begin exploring and ultimately colonizing areas of North America.

In 1492, the exploratory voyages of Christopher Columbus led to a transatlantic exchange, including migrations of European settlers during the Age of Discovery and the early modern period. Present-day cultural and ethnic patterns reflect interactions between European colonists, indigenous peoples, enslaved Africans, immigrants from Europe, Asia, and descendants of these respective groups.

The Convention of 1832 was the first political gathering of colonists in Mexican Texas. Delegates sought reforms from the Mexican government and hoped to quell the widespread belief that settlers in Texas wished to secede from Mexico. The convention was the first in a series of unsuccessful attempts at political negotiation that eventually led to the Texas Revolution.

Under the 1824 Constitution of Mexico, Texas was denied independent statehood and merged into the new state Coahuila y Tejas. After growing suspicion that the United States government would attempt to seize Texas by force, in 1830 Mexican President Anastasio Bustamante enacted the Law of April 6, 1830 which restricted immigration and called for customs duty enforcement. Tensions erupted in June 1832, when Texas residents systematically expelled all Mexican troops from eastern Texas. (Full article...)

A daguerreotype of the United States Capitol in 1846, with the original green copper dome as designed by Charles Bulfinch. Over time, extensions to both the north and south wings, made to accommodate the addition of new states to the Union, made the dome aesthetically displeasing, and as a result, it was replaced by a white cast iron dome which was completed in 1866.

Raymond Robert Emery ( Nichols; September 28, 1982 – July 15, 2018) was a Canadian professional ice hockey goaltender who played in the National Hockey League (NHL) for eleven seasons, between 2003 and 2015. Emery was chosen 99th overall by the Ottawa Senators in the 2001 NHL Entry Draft. During the 2006–07 season, he gained the starting job and backstopped his team to the Stanley Cup Finals, the first appearance in the finals for the modern Senators' franchise. However in the subsequent season, he lost his place as the team's starting goaltender due to an injury. He won a Stanley Cup championship with the Chicago Blackhawks in 2013.

In 2013, Emery won the William M. Jennings Trophy along with teammate Corey Crawford, awarded to the goaltender or goaltenders who give up the fewest goals in the season. Emery was a two-time Bill Masterton Memorial Trophy finalist for his dedication and perseverance. His teammates and fans often referred to him as "Razor" or "Sugar Ray" for his aggressive playing style. (Full article...)

N. ensifer worker specimen

Novomessor ensifer is a species of ant endemic to Mexico. A member of the genus Novomessor in the subfamily Myrmicinae, it was first described by Swiss entomologist Auguste Forel in 1899. N. ensifer was originally a part of the genus Aphaenogaster until a recent phylogenetic study concluded that Novomessor was genetically distinct and should be separated. The ant is a medium-sized species, measuring 5.5 to 10 millimetres (0.2 to 0.4 in). The ant is ferruginous-colored in some certain parts of the body, and small workers (nanitics) in incipient colonies are noticeably different in color and body structure.

N. ensifer is active throughout the day, where they forage on the ground and sometimes on low herbs. Colonies are found under stones and other objects in tropical dry forests and pine-oak forests. These ants are solitary foragers and predominantly feed on insects such as wasps and moths. The only known predator of N. ensifer is the giant horned lizard (Phrynosoma asio). While nothing is known about its reproduction, nuptial flight may take place during spring or summer, where queens establish their nests under stones and other objects. (Full article...)
