J Fish Biol 82:1086-92. 2013..In a separate experiment, P. promelas maintained at three water temperatures (7, 23 and 32° C) for 31 days did not differ in liver acrolein, a biomarker of oxidative stress...

Acorn mast drives long-term dynamics of rodent and songbird populationsEthan D Clotfelter
Department of Biology, Amherst College, Amherst, MA 01002, USA
Oecologia 154:493-503. 2007..Our results improve our understanding of the complex ecological interactions in oak-dominated forests by illustrating the importance of abiotic and biotic factors at different trophic levels...
Serotonin decreases aggression via 5-HT1A receptors in the fighting fish Betta splendensEthan D Clotfelter
Department of Biology, Amherst College, Amherst, MA 01002, United States
Pharmacol Biochem Behav 87:222-31. 2007..These results suggest a complex role for serotonin in the expression of aggression in teleost fishes, and that B. splendens may be a useful model organism in pharmacological and toxicological studies...
Cerebral lateralization and its relationship to phylogeny and aggression in anabantoid fishesEthan D Clotfelter
Department of Biology, Amherst College, Amherst, MA 01002, USA
Brain Behav Evol 69:169-75. 2007..We also used the PGLS method to reconstruct ancestral values for individual lateralization in this group of fishes, from which we conclude that the ancestral condition was one of low variance in eye-use preference...
Behavioral changes in fish exposed to phytoestrogensEthan D Clotfelter
Department of Biology, Amherst College, Amherst, MA 01002, USA
Environ Pollut 144:833-9. 2006..This suggests that phytoestrogen contamination has the potential to significantly affect the behavior of free-living fishes...
Reproductive consequences of exposure to waterborne phytoestrogens in male fighting fish Betta splendensLouise M Stevenson
Department of Biology, Amherst College, Amherst, MA 01002, USA
Arch Environ Contam Toxicol 60:501-10. 2011..We conclude that sexually mature male B. splendens are relatively immune to reproductive impairments from short-term exposure to waterborne phytoestrogens...
Experimental cooling during incubation leads to reduced innate immunity and body condition in nestling tree swallowsDaniel R Ardia
Department of Biology, Franklin and Marshall College, Lancaster, PA 17604, USA
Proc Biol Sci 277:1881-8. 2010..Our results indicate that environmental conditions and trade-offs experienced during one stage of development can have important carry-over effects on later life-history stages...
Temperature and life history: experimental heating leads female tree swallows to modulate egg temperature and incubation behaviourDaniel R Ardia
Program in Organismic and Evolutionary Biology, University of Massachusetts, Amherst, MA 01003, USA
J Anim Ecol 78:4-13. 2009..These results indicate that studies investigating the role of energetics in driving reproductive investment in intermittent incubators should consider egg temperature and individual variation more explicitly...
Fighting fish (Betta splendens) bubble nests do not inhibit microbial growthAlexandria C Brown
Department of Biology, Amherst College, Amherst, Massachusetts, USA
J Exp Zool A Ecol Genet Physiol 317:481-7. 2012..Our results confirm earlier work citing the importance of male nest attendance, and suggest that the mechanism responsible for decreased survival in the absence of attending males is pathogenic microbes...
Experimental heating reveals nest temperature affects nestling condition in tree swallows (Tachycineta bicolor)Jonathan H Pérez
Department of Biology, Amherst College, Amherst, MA 01002, USA
Biol Lett 4:468-71. 2008..These results indicate that investment in one life-history stage can have multiple pathways of carry-over effects on future life-history stages...

Department of Biology, Amherst College, Amherst, Massachusetts 01002, USA
Physiol Biochem Zool 83:333-42. 2010..Our data also suggest that the developmental transition from the barred to gold morph is not accompanied by a decrease in innate immunity in this species...
