Abstract
Effects of species’ traits and data characteristics on distribution models of threatened invertebrates.— The lack
of information about the distribution of threatened species inhibits the development of strategies for their conservation.
This is a particularly important problem when considering invertebrates. Here we evaluate the effects of
species’ traits and data characteristics on the accuracy of species distribution models (SDM) of 20 threatened
Iberian invertebrates. We found that the accuracy of the predictions was mostly affected by the characteristics
of the data. Species whose distributions were most accurately modelled were those with a greater sample size
or smaller relative occurrence area (ROA). Species in habitats that were difficult to detect using GIS data, such
as riparian species, tended to be more difficult to predict
