Institut Pluridisciplinaire Hubert Curien, University of Strasbourg, Strasbourg, France
Front Zool 10:33. 2013..Here, we investigated those two points in erythrocytes of one common avian model: the zebra finch (Taeniopygia guttata)...

- Experimental evidence that adult antipredator behaviour is heritable and not influenced by behavioural copying in a wild birdPierre Bize
Department of Ecology and Evolution, University of Lausanne, 1015 Lausanne, Switzerland
Proc Biol Sci 279:1380-8. 2012..Those findings provide strong evidence that antipredator behaviour of adult Alpine swifts is shaped by genetics and/or pre-hatching maternal effects taking place at conception but not by behavioural copying...
- Sudden weather deterioration but not brood size affects baseline corticosterone levels in nestling Alpine swiftsPierre Bize
Department of Ecology and Evolution, University of Lausanne, Biophore, Lausanne, Switzerland
Horm Behav 58:591-8. 2010..Apparently, short-term elevations of baseline corticosterone have no negative effects on nestling immunocompetence...

- Pheomelanin-based coloration and the ability to cope with variation in food supply and parasitismRomain Piault
Department of Ecology and Evolution, Biophore, University of Lausanne, 1015 Lausanne, Switzerland
Am Nat 174:548-56. 2009..This suggests that dark and pale pheomelanic owls reflect alternative adaptations to food availability and parasites, factors known to vary in space and time...
- Pale and dark reddish melanic tawny owls differentially regulate the level of blood circulating POMC prohormone in relation to environmental conditionsAlexandre Roulin
Department of Ecology and Evolution, University of Lausanne, Lausanne, Switzerland
Oecologia 166:913-21. 2011..Our findings support the hypothesis that the widespread links between melanin-based colouration and fitness components may be mediated, at least in part, by the melanocortin system...
- Effects of brood size manipulation and common origin on phenotype and telomere length in nestling collared flycatchersMarie Voillemot
Department of Ecology and Evolution, Biophore, University of Lausanne, Lausanne, Switzerland
BMC Ecol 12:17. 2012..We experimentally transferred hatchlings among brood triplets to create reduced, control (i.e. unchanged final nestling number) and enlarged broods...
- Body girth as an alternative to body mass for establishing condition indexes in field studies: a validation in the king penguinVincent A Viblanc
Department of Ecology and Evolution, Biophore, University of Lausanne, CH 1015 Lausanne, Switzerland
Physiol Biochem Zool 85:533-42. 2012..Body girth may prove a useful proxy to body mass for estimating body condition in field investigations and could likely provide similar information in other penguins and large animals that may be complicated to weigh in the wild...
- Melanin-based coloration is a nondirectionally selected sex-specific signal of offspring development in the alpine swiftPierre Bize

1 Division of Environmental and Evolutionary Biology, Graham Kerr Building, Glasgow University, Glasgow G12 8QQ, United Kingdom
Am Nat 171:107-18. 2008..These findings highlight the fact that giving host immunocompetence primary consideration can result in a biased appraisal of host-parasite interactions...
- A UV signal of offspring condition mediates context-dependent parental favouritismPierre Bize
Division of Environmental and Evolutionary Biology, University of Glasgow, Graham Kerr Building, Glasgow G12 8QQ, UK
Proc Biol Sci 273:2063-8. 2006..e. large stature). These results emphasize that parents use UV signals of offspring condition to adjust their feeding strategies depending on the ecological context...
- Female-biased infection and transmission of the gastrointestinal nematode Trichuris arvicolae infecting the common vole, Microtus arvalisAndreas Sanchez
Department of Ecology and Evolution, University of Lausanne, Biophore, 1015 Lausanne, Switzerland
Int J Parasitol 41:1397-402. 2011..These findings indicate that in this female-biased infection system females play a more important role than males in driving the dynamics of parasite transmission...
- Adoption as an offspring strategy to reduce ectoparasite exposurePierre Bize
Institute of Zoology, Division of Evolutionary Ecology, University of Bern, Baltzerstrasse 6, 3012 Bern, Switzerland
Proc Biol Sci 270:S114-6. 2003..Our findings emphasize what we believe to be a novel role for parasites in the evolution of adoption and, by extension, in the emergence of social interactions...
