Article
Evalynn M. Trumbo, Auteur ; Michael P. Ward, Auteur ; John N. Macey, Auteur ; Nathan A. Grigsby, Auteur ; Jeffrey D. Brawn, AuteurRecently fledged birds often experience low survival as they undergo rapid changes in their behavior, (e.g., habitat use, mobility, and foraging rate). For species of conservation concern, information about the post-fledging period can be critic[...]
Article
Henry S. Pollock, Auteur ; Todd M. Jones, Auteur ; Corey E. Tarwater, Auteur ; Elise T. Nishikawa, Auteur ; Jeffrey D. Brawn, AuteurEcological disturbance is an important factor that influences the abundance and distribution of species. Treefalls are a prominent source of disturbance in tropical forests, but robust characterization of community change after treefalls require[...]

Glen C. Sanderson, Auteur ; William L. Anderson, Auteur ; George L. Foley, Auteur ; Karen L. Duncan, Auteur ; Loretta M. Skowron, Auteur ; Jeffrey D. Brawn, Auteur ; James W. Seets, AuteurIn a 150-day study, we tested for chronic toxicity and effects on reproduction of bismuth/tin (Bi/Sn) alloy shot dosed in game-farm mallards (Anas platyrhynchos). Histopathology of livers, kidneys, gonads, hearts, and lungs showed no significant[...]
Article
Henry S. Pollock, Auteur ; Zachary A. Cheviron, Auteur ; T. J. Agin, Auteur ; Jeffrey D. Brawn, AuteurLocal abiotic conditions (microclimates) vary spatially and selection of favorable microclimates within a habitat can influence an animal's energy budgets, behavior, and ultimately, fitness. Insectivorous birds that inhabit the understory of tro[...]

Article
Corey E. Tarwater, Auteur ; Jeffrey D. Brawn, AuteurHow environmental conditions affect the timing and extent of parental care is a fundamental question in comparative studies of life histories. The post-fledging period is deemed critical for offspring fitness, yet few studies have examined this [...]
Article
Scott R. Loss, Auteur ; Marilyn O. Ruiz, Auteur ; Jeffrey D. Brawn, AuteurMaintaining biodiversity in urbanizing landscapes has become a top conservation priority. We examined variation in bird communities across a diverse array of urban and suburban neighborhoods in the Chicago, Illinois, metropolitan region. Rather [...]
Article
Jeffrey D. Brawn, Auteur ; GEORGE Angehr, Auteur ; Nicole Davros, Auteur ; W. Douglas Robinson, Auteur ; Jennifer N. Styrsky, Auteur ; Corey E. Tarwater, AuteurSurvival of offspring is a key fitness component and, for birds, the threat of predation on nests is especially influential. Data on rates of nest success from tropical regions are comparatively few, conservation-relevant, and essential for asse[...]
Article
Michael R. Cottam, Auteur ; Scott K. Robinson, Auteur ; Edward J. Heske, Auteur ; Jeffrey D. Brawn, Auteur ; Kevin C. Rowe, AuteurHabitat fragmentation fundamentally affects trophic interactions and ecosystem function. Understanding how the landscape matrix modulates such interactions can improve our understanding of fragmentation ecology. Studies of breeding birds provide[...]
Article
Todd M. Jones, Auteur ; Michael P. Ward, Auteur ; Thomas J. Benson, Auteur ; Jeffrey D. Brawn, AuteurPhenotypic traits developed in one life-history stage can carryover and affect survival in subsequent stages. For songbirds, carryover effects from the pre- to post-fledging period may be crucial for survival but are poorly understood. We assess[...]
