- Reproductive effort reduces long-term immune function in breeding tree swallows (Tachycineta bicolor)Daniel R Ardia
Department of Ecology and Evolutionary Biology, Cornell University, Ithaca, NY 14853 2701, USA
Proc Biol Sci 270:1679-83. 2003..We also found that individual quality, measured by clutch initiation date, mediated the effects of brood manipulations, with higher-quality birds showing a greater ability to deal with increases in effort...
- Immunosenescence in some but not all immune components in a free-living vertebrate, the tree swallowMaria G Palacios
Department of Ecology, Evolution, and Organismal Biology, Iowa State University, Ames, IA 50011, USA
Proc Biol Sci 274:951-7. 2007..Future research should focus on the ecological implications of immunosenescence and the potential causes of variation in patterns among species...
- Temperature effects on food supply and chick mortality in tree swallows (Tachycineta bicolor)David W Winkler
Department of Ecology and Evolutionary Biology, Cornell University, Ithaca, NY, USA
Oecologia 173:129-38. 2013..Regardless, all analyses reveal that, in an age of generally warmer climates, the largest effect of weather on swallow fledgling production is from cold temperatures...

- Longer telomeres associated with higher survival in birdsMark F Haussmann
Department of Ecology, Evolution and Organismal Biology, Iowa State University, 339 Science II, Ames, IA 50011, USA
Biol Lett 1:212-4. 2005..The survival advantage in the long telomere group continues for at least three breeding seasons. It will be important to identify mechanisms that link telomere length with survival early in life...
- Cell-mediated immunosenescence in birdsMark F Haussmann
Department of Ecology, Evolution and Organismal Biology, Iowa State University, Ames, Iowa 50011, USA
Oecologia 145:270-5. 2005..This link between declining immune function and survival may reflect differences in resource partitioning between species, and suggests that selection may act on investment in immune function to influence maximum life span...
- Phylogeny of swallows (Aves: Hirundinidae) estimated from nuclear and mitochondrial DNA sequencesFrederick H Sheldon
Museum of Natural Science, 119 Foster Hall, Louisiana State University, Baton Rouge, Louisiana 70803, USA
Mol Phylogenet Evol 35:254-70. 2005..The final group of hirundinines, the basal relicts, consists of a sister pair, the Australian Cheramoeca and African Pseudhirundo. The African saw-wings (Psalidoprocne) are their likely sister group...

Department of Ecology, Evolution and Organismal Biology, Iowa State University, Ames, IA 50011, USA
Ann N Y Acad Sci 1019:186-90. 2004..In zebra finches, the age-related change in telomerase activity varied in different tissues. Telomerase activity increased late in life in skeletal muscle, liver, and gonad, but not in blood or bone marrow...
