Here, Bruno Walther and colleagues review examples of sampling bias and the use of extrapolation methods for circumventing it. They also discuss the confounding effects of phylogenetic association on estimates of species richness.</style></abstract><issue><style face="normal" font="default" size="100%">8</style></issue><accession-num><style face="normal" font="default" size="100%">37450</style></accession-num><notes><style face="normal" font="default" size="100%">[INCOMPLETE: Add alternate journal title] Methods to quantify species richness are considered which are not affected by the confounding effects of uneven sampling effort.
