Collembola distribution is very broad because it can be found in a wide variety of habitats such as polar regions, deserts, sub-tropical and tropical regions (Greenslade 1996). BUAHPOKER.COM AGEN POKER DOMINO ONLINE UANG ASLI INDONESIA TERPERCAYA TANPA ROBOT Distribution of Collembola can with the help of soil particles and organic matter, can also with the help of wind or water. Family Hypogastruridae can be found both in the tropics and subtropics. Chrematocephalus genus, species C. celebensis has a cosmopolitan distribution, covering Japan, China, Sri Lanka, Indonesia, Papua, New Britain, and Australia (Suhardjono 1992). However, there are some species that are endemic terrestrial Collembola, even known to have a high level of endemism (Hopkin 1997). Examples Xenylla Handschin orientalis found only on the island of Java (Suhardjono 1992). Endemism can occur either because of natural selection, such as the existence of a natural barrier in the form of sea, soil properties, and how the spread (Suhardjono 1992).
2.1.6. Role Collembola to act as predatory nematodes and diatomaceous group (Suhardjono 1992). Collembola role in the food cycle as decomposer of organic matter or detritivor (Greenslade 1996; Hopkin 1997; Triplehorn & Johnson 2005) .. In the Collembola grown on soil mycorrhizal fungi and the control of disease in some plants. In the majority of the population of certain Collembola, funeral mycorrhizal root symbionts can stimulate growth and increase crop's growth. Collembola are important in stimulating or suppress microbial symbiosis around the roots of plants (Hopkin 1997).
2.1.7. Diversity Collembola have high species diversity resulting in differences in the classification of Collembola. Some experts classify as an order of the class Collembola Hexapoda or Insecta (Triplehorn & Johnson, 2005). Meanwhile, another group of experts classify taxon Collembola as a separate class from the class of insects (Suhardjono 1992, Hopkins 1997; Greenslade 1996). Determination of morphological characters between Collembola and insects indicate a difference in principle can separate from the class Insecta Collembola. These characters are the differences in leg segments, thorax, and abdomen. Additionally Collembola have ventral tube, LIGADAUN.COM AGEN TARUHAN BOLA PIALA DUNIA 2014 CASINO TANGKAS POKER ONLINE TERBAIK TERBESAR DAN TERPERCAYA furkula, tenaculum, and just have oseli (Suhardjono 1992).
According to Greenslade (1996) Collembola divided into three sub-orders, namely Arthropleona, Symphypleona, and Neelipleona. Arthropleona suborder includes species that have an elongated body, the boundary between the thorax and abdomen clear. While the sub-order spherical Neelipleona Symphypleona and the boundary between the body segments is less clear.
