On piecewise models and species-area patterns.

ABSTRACT:

Aim

Area thresholds, at which the form of the species-area relationship (SAR) changes abruptly, have played an important role in the theoretical framework of conservation biogeography and biodiversity research. The application of piecewise regressions has been advocated as a rigorous statistical technique to identify such thresholds within SARs, but a large variety of piecewise models remains untested. We explore the prevalence and number of thresholds in SARs and examine whether the currently widely used method for detecting the small island effect (SIE) is robust.

Location

Global.

Taxon

We consider all multicellular taxa based on the criteria of datasets selection.

Methods

We apply 15 regression models, including linear regression and piecewise regressions wi
