ABSTRACT We used a long‐term data set of black‐capped vireo (Vireo atricapilla) detection locations collected between May and June of 1990 through 2005 within the Wichita Mountains of Oklahoma, USA, to determine how presence‐only distribution m

The recent expansion of oil and gas extraction activity on the Great Plains, USA, has occurred with little understanding of potential effects of the activity on wildlife populations. We monitored the demography of breeding ferruginous hawks (Buteo re

Fecundity is fundamental to the fitness, population dynamics, conservation, and management of birds. For all the efforts made to measure fecundity or its surrogates over the past century of avian research, it is still mismeasured, misrepresented, and

After electrochemical or chemical oxidation of ferroceneboronic acid, the resulting ferriceniumboronic acid is found to react with tetrafluoborate to form ferricenyltrifluoborate. This reaction with a common electrolyte can be extended to other boron

Because of the difficulty of following female songbirds through an entire breeding season, field ornithologists are seldom able to directly measure seasonal fecundity (defined as number of offspring produced per female during an entire breeding seaso

Few studies have examined the potential consequences of cowbird (Molothrus spp.) parasitism on entire avian communities. Because cowbirds are host generalists, an obvious opportunity exists for such community-level effects. We developed a model to pr

The crystallographic data for several clathrochelate complexes of the form [M(NOX)3(BnBu)2] (where M = Co, Fe, Ru; NOX = 1,2-cyclohexanedione dioximato (C6H8N2O2); n-Bu = n-butyl) are presented. The data display an unexpected trend in distortio
