Māori People
The Māori (, ) are the indigenous Polynesian people of mainland New Zealand (). Māori originated with settlers from East Polynesia, who arrived in New Zealand in several waves of canoe voyages between roughly 1320 and 1350. Over several centuries in isolation, these settlers developed their own distinctive culture, whose language, mythology, crafts, and performing arts evolved independently from those of other eastern Polynesian cultures. Some early Māori moved to the Chatham Islands, where their descendants became New Zealand's other indigenous Polynesian ethnic group, the Moriori. Initial contact between Māori and Europeans, starting in the 18th century, ranged from beneficial trade to lethal violence; Māori actively adopted many technologies from the newcomers. With the signing of the Treaty of Waitangi in 1840, the two cultures coexisted for a generation. Rising tensions over disputed land sales led to conflict in the 1860s, and massive land confiscations, to whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rapa Fruit Dove
The Rapa fruit dove (''Ptilinopus huttoni'') is a species of bird in the family Columbidae, which includes pigeons and doves. It is endemic to the island of Rapa Iti in French Polynesia. The species was classified as Critically Endangered by the IUCN Red List in 2018 because of its small population and predicted continued decline. The Rapa fruit dove primarily feeds on fleshy fruit. Its natural habitat is subtropical or tropical moist lowland forests and it has an extent of 30 km2. It is threatened by habitat loss due to deforestation and invasive species. Effective land protection and management could increase the quality of habitat for the species. Additional research into population dynamics and the impact of threats to the species can give a better understanding of the conservation practices needed. Description and range The Rapa fruit dove is approximately 31 centimeters tall, making it a medium-sized dove. It is a colorful bird, with mostly green plumage, especially on ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horse Latitudes
The horse latitudes are the latitudes about 30 degrees north and south of the Equator. They are characterized by sunny skies, calm winds, and very little precipitation. They are also known as subtropical ridges, or highs. It is a high-pressure area at the divergence of trade winds and the westerlies. Origin of the term A likely and documented explanation is that the term is derived from the "dead horse" ritual of seamen (see Beating a dead horse). In this practice, the seaman paraded a straw-stuffed effigy of a horse around the deck before throwing it overboard. Seamen were paid partly in advance before a long voyage, and they frequently spent their pay all at once, resulting in a period of time without income. If they got advances from the ship's paymaster, they would incur debt. This period was called the "dead horse" time, and it usually lasted a month or two. The seaman's ceremony was to celebrate having worked off the "dead horse" debt. As west-bound shipping from Europe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humid Subtropical Climate
A humid subtropical climate is a zone of climate characterized by hot and humid summers, and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates. It is also known as warm temperate climate in some climate classifications. Under the Köppen climate classification, ''Cfa'' and ''Cwa'' climates are either described as humid subtropical climates or warm temperate climates. This climate features mean temperature in the coldest month between (or ) and and mean temperature in the warmest month or higher. However, while some climatologists have opted to describe this climate type as a "humid subtropical climate", Köppen himself never used this term. The humid subtropical climate classification was officially created under the Trewartha climate classification. In this classification, climates are termed humid subtropical when th ...

Trewartha Climate Classification
The Trewartha climate classification (TCC) or the Köppen–Trewartha climate classification (KTC) is a climate classification system first published by American geographer Glenn Thomas Trewartha in 1966. It is a modified version of the Köppen–Geiger system, created to answer some of its deficiencies. The Trewartha system attempts to redefine the middle latitudes to be closer to vegetation zoning and genetic climate systems. It was considered a more true or "real world" reflection of the global climate. The changes were seen as most effective on the large landmasses in Asia and North America, where many areas fall into a single group (''C'') in the Köppen–Geiger system. For example, under the standard Köppen system, Washington and Oregon are classed into the same climate zone (''Csb'') as parts of Southern California, even though the two regions have strikingly different weather and vegetation. Another example was classifying cities like London or Boston in the same cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Rainforest Climate
A tropical rainforest climate, humid tropical climate or equatorial climate is a tropical climate sub-type usually found within 10 to 15 degrees latitude of the equator. There are some other areas at higher latitudes, such as the coast of southeast Florida, USA, and Okinawa, Japan that fall into the tropical rainforest climate category. They experience high mean annual temperatures, small temperature ranges, and rain that falls throughout the year. Regions with this climate are typically designated ''Af'' by the Köppen climate classification. A tropical rainforest climate is typically hot, very humid, and wet. Description Tropical rain forests have a type of tropical climate in which there is no dry season—all months have an average precipitation value of at least . There are no distinct wet or dry seasons as rainfall is high throughout the months. One day in a tropical rainforest climate can be very similar to the next, while the change in temperature between day and night ...

Rapa Nui
Easter Island ( rap, Rapa Nui; es, Isla de Pascua) is an island and special territory of Chile in the southeastern Pacific Ocean, at the southeasternmost point of the Polynesian Triangle in Oceania. The island is most famous for its nearly 1,000 extant monumental statues, called ''moai'', which were created by the early Rapa Nui people. In 1995, UNESCO named Easter Island a World Heritage Site, with much of the island protected within Rapa Nui National Park. Experts disagree on when the island's Polynesian inhabitants first reached the island. While many in the research community cited evidence that they arrived around the year 800, there is compelling evidence presented in a 2007 study that places their arrival closer to 1200. The inhabitants created a thriving and industrious culture, as evidenced by the island's numerous enormous stone ''moai'' and other artifacts. However, land clearing for cultivation and the introduction of the Polynesian rat led to gradual deforest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thor Heyerdahl
Thor Heyerdahl KStJ (; 6 October 1914 – 18 April 2002) was a Norwegian adventurer and ethnographer with a background in zoology, botany and geography. Heyerdahl is notable for his ''Kon-Tiki'' expedition in 1947, in which he sailed 8,000 km (5,000 mi) across the Pacific Ocean in a hand-built raft from South America to the Tuamotu Islands. The expedition was designed to demonstrate that ancient people could have made long sea voyages, creating contacts between societies. This was linked to a diffusionist model of cultural development. Heyerdahl made other voyages to demonstrate the possibility of contact between widely separated ancient peoples, notably the ''Ra II'' expedition of 1970, when he sailed from the west coast of Africa to Barbados in a papyrus reed boat. He was appointed a government scholar in 1984. He died on 18 April 2002 in Colla Micheri, Italy, while visiting close family members. The Norwegian government gave him a state funeral in Oslo Cat ...
