Biodiversity is an expression of the presence of a wide variety of forms of expression, the number and nature of communion yangterlihat at different levels of living beings, namely tingkatekosistem, type and genetics. In assessing the potential of biodiversity, which is more often the center of attention is the diversity of species, because it is most easily observed, while the genetic diversity that is the preparation of these species are generally more difficult to identify. Biodiversity is the number of species present in an area. In another sense; biodiversity refers to diversity of all kinds of plants, animals and micro-organisms (microorganisms), as well as ecosystems and ecological processes in which they are a part (Act No. 5 of 1994 on Ratification UNCBD). Genetic diversity (in kind) cover the entire genetic information as a carrier of offspring traits of all living beings. Diversity of species related to the diversity of organisms or species that have a specific geneti...

Ecosystem is a higher level of organization of the community or a union of a community with its environment where there interrelationships. According to Susanto (2000) is a unit of ecosystem environment in which there are systematic functional relationships among living things and between the living and abiotic environmental components. Freshwater ecosystems is an ecosystem with its habitat is often flooded with fresh water rich in minerals with a pH of about 7, the water level conditions are not always fixed, sometimes up and down, even once can also dry out. To measure the levels of pollution of the waters can be done by measuring the abiotic factors or the presence of macrozoobenthos. The existence and abundance of macrozoobenthos in a body of water can be influenced by physical and chemical factors. The amount of oxygen levels   dissolved in a water then the water is a good habitat for biota living so high species diversity index value. The higher the index value diversity m...

A. Definition of Community Community is a collection of various populations who live at a time and specific regions that interact and influence each other. Community has a degree of integration is more complex when compared with individuals and populations. B. Community Name Name of the community should be able to provide information on the nature of the community. The most simple way, naming it by using words which may indicate how the form communities like grasslands, deserts, forests of teak. The best way to call the community is to take some clear and steady nature, whether living or not. This summary is based on the naming of the community can: 1. Establish or major structures like the kind of dominant form of life or other indicators such as the pine forest, forest agathis, teak forests, or forests Dipterocarphaceae, can also be based on the nature of the dominant vegetation such as forests sclerophyll 2. Based on the physical habitat of the community, such as commun...

HABITAT Habitat an organism is a living organism, or a place where one should go to find these organisms. The term habitat is widely used, not only in ecological but everywhere. But in general the term is defined as the life of a living being. Habitat namely resources and conditions that exist in an area that is occupied by a species impact. Habitat is an organism-specific: it connects the presence of species, populations, or idndividu (animal or plant) with an area of physical and biological characteristics. Habitat consists of more than just vegetation or the vegetation structure; a number of special resource needs of a species. Wherever an organism given the resources that affect the ability to survive, that's called habitat. Availability of habitat refers to the accessibility of the physical and biological components that are needed by animals, in contrast to the abundance of resources that only shows the quantity of each organism habitats that exist in these habitats...

Biodiversity is defined as the diversity of beings and things that related to the environment such creatures. Diversity includes two levels: 1.      Genetic diversity, a diversity that is the best, because this diversity can continue and be lowered. Genetic diversity is associated with distinctive ecological and evolutionary processes. 2.      Diversity of species, including flora and fauna. Diverse types of behavior, life strategies, shape, chain food, space and also the dependence between the type of one another. The existence of high diversity will produce a steady environmental stability. The diversity of species is also called the heterogeneity of types, is a unique characteristic to describe the community structure in the organization's life. A community is said to have high species diversity, if the abundance of each kind of high and low species diversity conversely if only tar-be some kind of abundance. Diversity index can be us...
