Solving Problems with Nature - Naturally. New Hampshire has weasels in abundance. In fact, there are six members of the mustelidae, or weasel family. They include (from smallest to largest): ermine (also known as the short-tailed weasel), long-tailed weasel, pine marten, mink, fisher and river otter.
Descriptive Cross-Sectional Study A descriptive cross-sectional study is a study in which the disease or condition and potentially related factors are measured at a specific point in time for a defined population. Cross-sectional studies can be thought of as a snapshot of the frequency and characteristics of a condition in a population at a particular point in time. This type of data can be used to assess the prevalence of conditions in a population.
