Spatial pattern of nesting trees in the (a) Chamela, (b) Careyes, and (c) Cuixmala areas in the Chamela—Cuixmala Biosphere Reserve from 1995 to 2007. Ripley's K function is presented after linearization, L (r), over distance by a solid line; confidence envelopes are indicated by dashed lines. Values above the upper envelope indicate a clustered spatial distribution. Values below the lower envelope indicate an overdispersed spatial distribution.
