Quantifying biodiversity: procedures and pitfalls in the measurement and comparison of species richness
Species richness is a fundamental measurement of community and regional diversity, and it underlies many ecological models and conservation strategies. In spite of its importance, ecologists have notExpand

Estimating terrestrial biodiversity through extrapolation.
Both the magnitude and the urgency of the task of assessing global biodiversity require that we make the most of what we know through the use of estimation and extrapolation. Likewise, futureExpand

A general binomial mixture model is proposed for the species accumulation function based on presence-absence (incidence) of species in a sample of quadrats or other sampling units. The model coversExpand

Models and estimators linking individual-based and sample-based rarefaction, extrapolation and comparison of assemblages
Aims In ecology and conservation biology, the number of species counted in a biodiversity study is a key metric but is usually a biased underestimate of total species richness because many rareExpand

A new statistical approach for assessing similarity of species composition with incidence and abundance data
The classic Jaccard and Sorensen indices of compositional similarity (and other indices that depend upon the same variables) are notoriously sensitive to sample size, especially for assemblages withExpand

Rarefaction and extrapolation with Hill numbers: a framework for sampling and estimation in species diversity studies
Quantifying and assessing changes in biological diversity are central aspects of many ecological studies, yet accurate methods of estimating biological diversity from sampling data have been elusive.Expand

Statistical methods for estimating species richness of woody regeneration in primary and secondary rain forests of northeastern Costa Rica
The study of plant communities requires a basic understanding of the abundance, distribution, and number of species present. Yet, in obtaining this information, scientists can rarely sample theExpand

Global Warming, Elevational Range Shifts, and Lowland Biotic Attrition in the Wet Tropics
Many studies suggest that global warming is driving species ranges poleward and toward higher elevations at temperate latitudes, but evidence for range shifts is scarce for the tropics, where theExpand

The Mid‐Domain Effect and Species Richness Patterns:What Have We Learned So Far?
If species' ranges are randomly shuffled within a bounded geographical domain free of environmental gradients, ranges overlap increasingly toward the center of the domain, creating a “mid‐domain”Expand

Nonbiological Gradients in Species Richness and a Spurious Rapoport Effect
G. C. Stevens showed that an equatorward increase in species richness is often paralleled by a decrease in the mean latitudinal range of species-a pattern he called Rapoport's rule. He reported aExpand
