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...
Genetic structure of breeding and wintering populations of Swainson'S Warbler (2008)
Swainson's Warbler (Limnothlypis swainsonii) is a species of conservation concern because of its small wintering range in the Caribbean Basin, relatively low population densities, and habitat...
Wright, Timothy F., Schirtzinger, Erin E., Matsumoto, Tania, Eberhard, Jessica R., Graves, Gary R., Sanchez, Juan J., ...
The question of when modern birds (Neornithes) first diversified has generated much debate among avian systematists. Fossil evidence generally supports a Tertiary diversification, whereas estimates...
A hummingbird specimen from Ramsey Canyon, Huachuca Mountains, southeastern Arizona, represents a hybrid of Lampornis clemenciae (Blue-throated Hummingbird) × Calypte anna (Anna's Hummingbird). The...
A hummingbird specimen collected by W. W. Brown in 1917 in the Huachuca Mountains, southeastern Arizona, is a hybrid of Hylocharis leucotis (white-eared hummingbird) × Selasphorus platycercus...
The unique hummingbird specimen collected by J. W. Sefton, Jr., in 1932 in the Rincon Mountains, southeastern Arizona, is confirmed to be a hybrid, Calypte costae × Selasphorus platycercus. The...
AVIAN HEMATOZOA IN SOUTH AMERICA: A COMPARISON OF TEMPERATE AND TROPICAL ZONES (2006)
Kate L. Durrant, Jon S. Beadell, Farah Ishtiaq, Gary R. Graves, Storrs L. Olson, Eben Gering, ...
Venezuela: An Effects-Based Strategy for the 21st-Century (2006)
In the post 9/11 global security environment, it is evident that the United States is confronting numerous political, military and economic threats dispersed throughout the international community....
HABITAT CHARACTERISTICS IN THE CORE BREEDING RANGE OF THE SWAINSON'S WARBLER (2002)
I investigated the physiognomic and floristic characteristics of Swainson's Warbler (Limnothlypis swainsonii) territories at five localities within its core breeding range in Arkansas, Mississippi,...
A survey of duties and responsibilities of teacher aides in the senior high school. (1969)
Title on spine: Survey of teacher aide duties and responsibilities.
Multiscale assessment of patterns of avian species richness
Rahbek, Carsten, Graves, Gary R.
The search for a common cause of species richness gradients has spawned more than 100 explanatory hypotheses in just the past two decades. Despite recent conceptual advances, further refinement of...
Stable isotope signature of philopatry and dispersal in a migratory songbird
Graves, Gary R., Romanek, Christopher S., Rodriguez Navarro, Alejandro
Stable isotope analysis is widely promoted as a practical method for tracing the geographic origins of migratory birds. However, the extent to which geospatial patterns of isotope ratios in avian...
Source pool geometry and the assembly of continental avifaunas
Graves, Gary R., Rahbek, Carsten
Classical niche-assembly models propose that the composition of biotic communities in continental landscapes is determined chiefly by the autecology of species, interspecific competition, and the...

Global phylogeographic limits of Hawaii's avian malaria
Beadell, Jon S, Ishtiaq, Farah, Covas, Rita, Melo, Martim, Warren, Ben H, Atkinson, Carter T, ...
The introduction of avian malaria (Plasmodium relictum) to Hawaii has provided a model system for studying the influence of exotic disease on naive host populations. Little is known, however, about...
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...
Malarial parasites as geographical markers in migratory birds?
Fallon, Sylvia M, Fleischer, Robert C, Graves, Gary R
We tested the hypothesis that malarial parasites (Plasmodium and Haemoproteus) of black-throated blue warblers (Dendroica caerulescens) provide sufficient geographical signal to track population...
