Aleipata Islands
The Aleipata Islands are a group of four uninhabited islands off the eastern end of Upolu Island, Samoa. The islands are eroded volcanic tuff rings, and consist of a small northern pair on Upolu's barrier reef, and a larger southern pair outside it. Collectively the islands have an area of about . Administratively, the islands are part of the Atua district. The islands are important for Samoa's biodiversity and are protected by the Aleipata Marine Protected Area. Geography From north to south, the islands consist of: *Namua (0.20 km2) *Fanuatapu (0.15 km2) * Nuʻutele (1.08 km2) * Nuʻulua (0.25 km2) Namua and Fanuatapu lie at the outer edge of the fringing reef of Upolu, at a distance of 0.7 km and 2.5 km, respectively, from Upolu Island itself. Nuʻutele and Nuʻulua are 4 to 6 km further south, outside the fringing reef, and lie 1.4 km 3.5 km off Cape Tapaga, which is the southeastern headland of Upolu. Only Namua is open for visit ...

Volcanoes Of Samoa
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide pa ...

Geography Of Samoa
The Samoan archipelago is a chain of 16 islands and numerous seamounts covering in the central South Pacific, south of the equator, about halfway between Hawaii and New Zealand, forming part of Polynesia and of the wider region of Oceania. The islands are Savaiʻi, Upolu, Tutuila, ’Uvea, Taʻū, Ofu, Olosega, Apolima, Manono, Nuʻutele, Niulakita, Nuʻulua, Namua, Fanuatapu, Rose Atoll, Nu'ulopa, as well as the submerged Vailuluʻu, Pasco banks, and Alexa Bank. Tectonics The Samoan archipelago has many features that are consistent with a plume-driven hotspot model, including the currently active submarine volcano Vailuluʻu that anchors the eastern extremity. However, the chain's proximity to the northern end of the Tonga trench, and the presence of voluminous young volcanism on what should be the oldest (~5 my) western island Savaiʻi has induced controversy regarding a simple plume/hotspot model. The Samoan archipelago was most likely created by the Pacific Te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samoan Islands
The Samoan Islands ( sm, Motu o Sāmoa) are an archipelago covering in the central South Pacific, forming part of Polynesia and of the wider region of Oceania. Administratively, the archipelago comprises all of the Independent State of Samoa and most of American Samoa (apart from Swains Island, which is geographically part of the Tokelau Islands). The land masses of the two Samoan jurisdictions are separated by of ocean at their closest points. The population of the Samoan Islands is approximately 250,000. The inhabitants have in common the Samoan language, a culture known as '' fa'a Samoa,'' and an indigenous form of governance called '' fa'amatai''. Samoans are one of the largest Polynesian populations in the world, and most are of exclusively Samoan ancestry. The oldest known evidence of human activity in the Samoan Islands dates to around 1050 BCE. It comes from a Lapita site at Mulifanua wharf on Upolu island.

Brodifacoum
Brodifacoum is a highly lethal 4-hydroxycoumarin vitamin K antagonist anticoagulant poison. In recent years, it has become one of the world's most widely used pesticides. It is typically used as a rodenticide, but is also used to control larger pests such as possum.Eason, C.T. and Wickstrom, M. ''Vertebrate pesticide toxicology manual'', New Zealand Department of Conservation Brodifacoum has an especially long half-life in the body, which ranges up to nine months, requiring prolonged treatment with antidotal vitamin K for both human and pet poisonings. It has one of the highest risks of secondary poisoning to both mammals and birds.Rodenticides: Topic Fact Sheet |
Polynesian Rat
The Polynesian rat, Pacific rat or little rat (''Rattus exulans''), known to the Māori as ''kiore'', is the third most widespread species of rat in the world behind the brown rat and black rat. The Polynesian rat originated in Southeast Asia, and like its relatives has become widespread, migrating to most of Polynesia, including New Zealand, Easter Island, and Hawaii. It shares high adaptability with other rat species extending to many environments, from grasslands to forests. It is also closely associated with humans, who provide easy access to food. It has become a major pest in most areas of its distribution. Description The Polynesian rat is similar in appearance to other rats, such as the black rat and the brown rat. It has large, round ears, a pointed snout, black/brown hair with a lighter belly, and comparatively small feet. It has a thin, long body, reaching up to in length from the nose to the base of the tail, making it slightly smaller than other human-associated r ...
