Patterns and causes of species richness: a general simulation model for macroecology (2009)

Gotelli, Nicholas J., Anderson, Marti J., Hector, T. Arita, Chao, Anne, Colwell, Robert K., Connolly, Sean R., ...

Understanding the causes of spatial variation in species richness is a major research focus of biogeography and macroecology. Gridded environmental data and species richness maps have been used in...

A new statistical approach for assessing similarity of species composition with incidence and abundance data

Interpolating, extrapolating, and comparing incidence-based species accumulation curves (2004)

Robert K. Colwell, Chang Xuan Mao, Jing Chang

Abstract. 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...

The Evolution of Ecology (1985)

COLWELL, ROBERT K.

In spite of an early history of interaction, progress in the fields of ecology and evolutionary biology during most of this century has been made largely in parallel, with little creative exchange...

Community Organization Among Neotropical Nectar-Feeding Birds (1978)

FEINSINGER, PETER, COLWELL, ROBERT K.

Assemblages of neotropical hummingbirds are organized according to parameters of available resources and morphological-behavioral attributes of particular hummingbird species. We distinguish five...

Predicting continental-scale patterns of bird species richness with spatially explicit models

Rahbek, Carsten, Gotelli, Nicholas J, Colwell, Robert K, Entsminger, Gary L, Graves, Gary R

The causes of global variation in species richness have been debated for nearly two centuries with no clear resolution in sight. Competing hypotheses have typically been evaluated with correlative...
