The fact that the local richness of communities is not strictly dependent on local conditions
but is also affected by regional richness was recently stressed (Cornell and Lawton 1992,
Cornell 1993, Schluter and Ricklefs 1993). According to Cornell and Lawton (1992) local
species richness (LSR) and regional species richness (RSR) are interrelated in various
ways. Graphically, two endpoints along a continuum can be distinguished: proportional
sampling (linear relationship between the two variables, Type I curve) and ceiling (local …
