Sentence examples for absence data for from inspiring English sources

To generate absence data for each of the 2068 species with at least 2 specimens, we generated a random (from 1 to 54) number of informed pseudo-absence data by randomly sampling points from outside the species' range map.

This model can also be used to analyse DArT marker data sets due to the underlying assumptions for the restriction sites model, non-observable absence data for example, fitting the structure of DArT data.

Geographic data for specimens is generally less than optimal and is unevenly distributed across taxa, due to the bias of collecting activities toward particular species or locations, a historically insufficient prioritization of recording and maintaining of geographic data, lack of high quality absence data for species, and limited accessibility of stored data for some collections.

Species turnover in sequential frog vs. lizard communities was compared using the mean Jaccard's dissimilarity value between all chronosere pairs calculated from separate presence absence data for the two groups [ 36].

Spatial model outputs using observed presence and absence data for Aedes albopictus, an invasive species in (Southern) Europe, obtained through an international network of scientific collaborators, are then compared to potential distribution maps computed using a multicriteria decision analysis approach (MCDA) based on expert knowledge.
