1. The process of incorporating observations about a situation or phenomenon into a framework of prior knowledge, allowing one to propose possible explanations for it. This type of reasoning is necessary for the formulation of hypotheses using the scientific method. 2. Using specific observations or accepted scientific facts to develop tentative explanations for situations or phenomena. This process often involves the use of analogies in developing possible explanations, also known as hypotheses.

The final step in the scientific method. After the experiment is conducted, the expected result is compared to the observed result, and a determination is made that the research hypothesis is either valid or invalid. If deemed invalid, a new or alternate hypothesis must be developed, and the scientific research process (scientific method) starts anew.

1. The process of moving from general evidence, principles, or nonobservable explanations to specific observable actions, consequences, or conclusions. 2. In the scientific method, deductive reasoning is used to determine the specific observations, measurements, or other data that will either support or contradict the research hypothesis.

1. Variation in the physical characteristics of ecosystems across a landscape caused by variation in soil, slope, aspect, elevation, climate, and geology, and the accompanying variation in biotic communities. Also known as ecological or biological diversity.

1. The anticipated outcome of a scientific experiment according to the research hypothesis. 2. In the scientific method, the expected result is the outcome of the experiment if the research hypothesis is true.

The process used to test research hypotheses in the scientific method. In order to be useful in scientific inquiry, an experiment should be objective, with reliable and verifiable data. In addition, the results of the experiment must be reproducible by other scientists.

An explanation for natural or other phenomena, developed using abductive reasoning following observation (the scientific method). The hypothesis is tested through the use of designed experiments, and shown to be either valid or invalid. If the original research hypothesis is deemed invalid, a new hypothesis must be developed, often based on further ovservation as well as the results from the previous experiment(s).

The first step in the scientific method, observation is the act of examining, inspecting, or scrutinizing natural or other phenomena in such a manner that leads to the use of abductive reasoning to explain them.

The actual outcome of a designed experiment using the scientific method. This outcome is compared to the expected outcome as described in the research hypothesis, and a conclusion is made that the experimental data either supports or contradicts the hypothesis.

1. A unit of length or area equal to one linear rod or one square rod, commonly used in land surveys. The terms, rod, pole, and perch are equivalent and may be used interchangeably, although "rod" is the most common. One (1) pole is equal to 25 links, 16.5 feet, or 1/4 (0.25) chain. For conversions and examples, see Rod, pole, or perch equivalents and conversions and the various Converting rods, poles, or perches to... entries.
2. A roundwood product used primarily for structural support. Tree species used for poles are selected for resistance to weather, wear, and mechanical stress and include lodgepole pine, Douglas-fir, western hemlock, and a variety of southern pines.
3. Term applied to trees that have too small a diameter to be considered sawlogs, but are useful as structural supports, flagpoles, etc.
4. The end of an axis, as in poles of the earth or of cellular mitotic spindles in plants and animals.
5. Either of two opposing parts, forces, or situations, as in magnets, batteries, or opinions.

Definition:
1. Biology, Ecology, Forestry: A species of plant or animal existing in geographic or temporal isolation; plants or animals that exist in local areas smaller than their historic ranges, either from an earlier time period or as some of the last remaining examples of nearly extinct species.
2. Restoration: Isolated areas of ecosystems that have not been impacted by human activities and are still subject to a historic and natural disturbance regime.
3. Geology: Minerals, rocks, or other geologic structures or features that remain after the exterior material that previously covered or surrounded them is no longer there, as through erosion or chemical reaction.

The outcome of an experiment conducted using the scientific method. This observed result is compared to the expected result according to the research hypothesis, and a conclusion is made about whether the results support or contradict the hypothesis.

1. The series of rational steps that leads to the proof (or disproof) of a scientific or research hypothesis. The steps are observation, which leads to the formulation of a hypothesis through abductive reasoning, followed by tests or experiments to determine the validity of the hypothesis (deductive reasoning). The observed result of the experiment is compared to the expected result, and a conclusion is made supporting or contradicting the hypothesis. 2. The scientific method is the process by which scientific facts are discovered, proven, or learned.
