Abstract
A common problem in applied ecology is to determine whether the diversity o f a biological community declines along a gradient. This note describes a s tatistical test for such a decline. The test is based on a combination of n onlinear optimization and a parametric bootstrap, An illustration involving late Cretaceous dinosaur diversity is presented.
