Long-term bird population studies in the United States
Autor: Raymond J. O'Connor
Publikováno v: Ibis. 133:36-48
Long-term population studies of birds in the United States have been less species-oriented and more concept-oriented than in Britain. The demographics of North American species do not differ grossly from those of species elsewhere in the world, but p

DIFFERENTIAL GROWTH AND BODY COMPOSITION IN ALTRICIAL PASSERINES
Autor: Raymond J. O'Connor
Publikováno v: Ibis. 119:147-166
SUMMARY The differential development of various body organs and of fat, water, and other constituents was studied in three species with altricial nestlings—Blue Tit, House Martin and House Sparrow. In all species resources available at each stage o

Effect of dispersal at range edges on the structure of species ranges
Autor: Volker Bahn, Raymond J. O'Connor, William B. Krohn
Publikováno v: Oikos. 115:89-96
Range edges are of particular interest to ecology because they hold key insights into the limits of the realized niche and associated population dynamics. A recent feature of Oikos summarized the state of the art on range edge ecology. While the typi

How Well do Consistently Monitored Breeding Bird Survey Routes Represent the Environments of the Conterminous United States?
Autor: Joshua J. Lawler, Raymond J. O'Connor
Publikováno v: The Condor. 106:801-814
We investigated the degree to which consistently monitored Breeding Bird Survey (BBS) routes represented environmental conditions across the United States. Using 388 models of individual species distributions, we identified eight environmental variab

The effects of habitat resolution on models of avian diversity and distributions: a comparison of two land-cover classifications
Autor: Denis White, Raymond J. O'Connor, Joshua J. Lawler, Carolyn T. Hunsaker, Thomas R. Loveland, K. Bruce Jones
Publikováno v: Landscape Ecology. 19:517-532
Quantifying patterns is a key element of landscape analysis. One aspect of this quantification of particular importance to landscape ecologists is the classification of continuous variables to produce categorical variables such as land-cover type or
