Overview

An AssertedDistribution is the Source-backed assertion that a taxon (OTU) is present in some *spatial area*. It requires a Citation indicating where/who made the assertion. In TaxonWorks the areas are drawn from GeographicAreas and Gazetteers.

AssertedDistributions can be asserts that the source indicates that a taxon is NOT present in an area. This is a “positive negative” in , i.e. the Source can be thought of recording evidence that a taxon is not present. TaxonWorks does not differentiate between types of negative evidence.
