TL;DR: Cost-efficient ecological and natural resource surveys need: (1) flexible, logistically simple, and statistically sound sampling methods, and (2) sensitive, computationallysimple, and ecologically robust data analysis methods.

TL;DR: A Monte Carlo method for determining the statistical significance of scale—dependent discontinuities is described and a nonparametric, scale—independent method is proposed that is more appropriate for locating statistically significant discontinUities that separate different, relatively homogeneous groups of varying size along a series.

TL;DR: In this paper, the authors studied distribution patterns of vascular plant species and environmental variables along a permanent transect traversing a closed-drainage watershed in the northern Chihuahuan Desert of south-central New Mexico, USA.

TL;DR: In this article, two nonparametric methods for determining the statistical significance of discontinuities detected by split moving-window boundary analysis (SMW) are presented. And they are used to locate boundaries between vegetation samples collected at systematic intervals across a desert landscape in southern New Mexico.

TL;DR: In this article, spatial patterns of vegetation on an ephemeral lake bed (playa) in the northern Chihuahuan desert were closely correlated with elevation, and the complete turnover in species composition across this transect, with an elevation change of only 85 cm, indicates that environmental gradients resulting from flooding and soil development are steep.
