J Comp Physiol B 178:829-35. 2008..In contrast, circulating carotenoids and body mass increased in both groups. These results suggest that stress hormones, such as corticosterone, may also act as modulators of oxidative stress in birds...
Long flights and age affect oxidative status of homing pigeons (Columba livia)David Costantini
Division of Neuroanatomy and Behaviour, Institute of Anatomy, University of Zurich, Winterthurerstrasse 190, CH 8057 Zurich, Switzerland
J Exp Biol 211:377-81. 2008..The results of the study suggest that long flights may cause oxidative stress, and that older individuals may experience higher physiological demands...
Aggressive and non-aggressive personalities differ in oxidative status in selected lines of mice (Mus musculus)David Costantini
Division of Neuroanatomy and Behaviour, Institute of Anatomy, University of Zurich, Winterthurerstrasse 190, 8057 Zurich, Switzerland
Biol Lett 4:119-22. 2008..This suggests that different animal personalities may be accompanied by differences in oxidative status, which may predict differences in longevity...
Male-biased predation of western green lizards by Eurasian kestrelsDavid Costantini
Dipartimento di Biologia Animale e dell Uomo, Universita La Sapienza, Viale dell Università 32, Rome, Italy
Naturwissenschaften 94:1015-20. 2007..Overall predation rates on lizards differed between habitats, depending on the year. We propose that the observed sex-biased predation is mainly due to sex differences in lizard behaviour...
Effects of carotenoid supplementation on colour expression, oxidative stress and body mass in rehabilitated captive adult kestrels (Falco tinnunculus)David Costantini
Dipartimento di Biologia Animale e dell Uomo, Universita La Sapienza, Viale dell Università 32, 00185, Rome, Italy
J Comp Physiol B 177:723-31. 2007..Our findings suggest that, above a certain physiological threshold, carotenoids can cause detrimental effects. This is relevant for the trade-off between expression of sexual signals and the costs of maintaining/producing them...
MF magnitude does not affect body condition, pro-oxidants and anti-oxidants in Eurasian kestrel (Falco tinnunculus) nestlingsDavid Costantini
Dipartimento di Biologia Animale e dell Uomo, Universita La Sapienza, Viale dell Università 32, 00185 Roma, Italy
Environ Res 104:361-6. 2007..Comparisons with values recorded in nestlings from non-exposed nests seem to confirm the absence of any effect of exposure to MFs produced by power lines on the variables considered...
Carotenoid availability does not limit the capability of nestling kestrels (Falco tinnunculus) to cope with oxidative stressDavid Costantini
Dipartimento di Biologia Animale e dell Uomo, Universita La Sapienza, Viale dell Università 32, 00185 Roma, Italy
J Exp Biol 210:1238-44. 2007..Our results show that (i) in general, younger nestlings actually have to cope with a high free radical production, and (ii) the ability of wild nestling kestrels to cope with oxidative stress is not affected by carotenoid availability...
Oxidative damage and anti-oxidant capacity in two migratory bird species at a stop-over siteDavid Costantini
Dipartimento di Biologia Animale e dell Uomo, Universita La Sapienza, Viale dell Università 32, 00185 Roma, Italy

J Comp Physiol B 176:329-37. 2006..These findings suggest that intrabrood sibling competition could play a role in determining oxidative stress, and that in carnivorous birds other antioxidant molecules could be more important than carotenoids to reduce oxidative stress...

PCBs in the eggs of Eurasian kestrels indicate exposure to local pollutionGiacomo Dell'omo
Ornis italica, Rome, Italy
