Importance of melanin‐based colouration and environment in shaping intracellular glutathione levels in nestling and adult tawny owls Strix aluco

Autor: Guillaume Emaresi, Pierre Bize, Alexandre Roulin

Publikováno v: Journal of Avian Biology, Vol 2022, Iss 2, Pp n/a-n/a (2022)

Resources allocated in reproduction are traded off against those invested in self‐maintenance such as antioxidant response. Glutathione (GSH) is an intracellular antioxidant defence that scavenges reactive oxygen species, the deleterious byproducts

Sex- and melanin-specific variations in the oxidative status of tawny owls in response to manipulated reproductive effort

Autor: Isabelle Henry, Pierre Bize, Esther Gonzalez, Alexandre Roulin, Guillaume Emaresi

Publikováno v: Journal of Experimental Biology
The Journal of experimental biology, vol. 219, no. Pt 1, pp. 73-79

Oxidative stress, determined by the balance between the production of damaging reactive oxygen species (ROS) and antioxidant defences, is hypothesised to play an important role in shaping the cost of reproduction and life history trade-offs. To test

Landscape genetics of the Alpine newt ( Mesotriton alpestris ) inferred from a strip-based approach

Autor: Luca Fumagalli, Guillaume Emaresi, Jérôme Pellet, Alexandre H. Hirzel, Sylvain Dubey

Publikováno v: Conservation Genetics, vol. 12, no. 1, pp. 41-50

Habitat destruction and fragmentation are known to strongly affect dispersal by altering the quality of the environment between populations. As a consequence, lower landscape connectivity is expected to enhance extinction risks through a decrease in

Melanin-specific life-history strategies

Autor: Isabelle Henry, Julien Gasparini, Valentijn van den Brink, Guillaume Emaresi, Res Altwegg, Alexandre Roulin, Pierre Bize

Publikováno v: American Naturalist, vol. 183, no. 2, pp. 269-280
The American Naturalist

The maintenance of genetic variation is a long-standing issue because the adaptive value of life-history strategies associated with each genetic variant is usually unknown. However, evidence for the coexistence of alternative evolutionary fixed strat

Pleiotropy in the melanocortin system: expression levels of this system are associated with melanogenesis and pigmentation in the tawny owl (Strix aluco)

Autor: Hannes Richter, Céline Simon, Pierre Bize, Guillaume Emaresi, Alexandre Roulin, Anne-Lyse Ducrest

Publikováno v: Molecular ecology. 22(19)

The adaptive function of melanin-based coloration is a long-standing debate. A recent genetic model suggested that pleiotropy could account for covariations between pigmentation, behaviour, morphology, physiology and life history traits. We explored

Pale and dark reddish melanic tawny owls differentially regulate the level of blood circulating POMC prohormone in relation to environmental conditions

Autor: Guillaume Emaresi, Julien Gasparini, Romain Piault, Alexandre Roulin, Pierre Bize, Anne-Lyse Ducrest

Oecologia, 166(4), 913-921. SPRINGER

Knowledge of the hormonal pathway controlling genotype-specific norms of reaction would shed light on the ecological factors to which each genotype is adapted. Environmentally mediated changes in the sign and magnitude of covariations between heritab

Buccal swabs allow efficient and reliable microsatellite genotyping in amphibians

Conservation Genetics, 2007, 8 (2), pp.509-511. ⟨10.1007/s10592-006-9180-3⟩

Buccal swabs have recently been used as a minimally invasive sampling method in genetic studies of wild populations, including amphibian species. Yet it is not known to date what is the level of reliability for microsatellite genotypes obtained using

Low Y chromosome variation in Saudi-Arabian hamadryas baboons (Papio hamadryas hamadryas)

Autor: Guillaume Emaresi, Nicolas Perrin, Anabelle Reber, Robert L. Hammond, Lori Lawson Handley

Publikováno v: Heredity. 96(4)

It is important to characterise the amount of variation on the mammalian Y chromosome in order to assess its potential for use in evolutionary studies. We report very low levels of polymorphism on the Y chromosome of Saudi-Arabian hamadryas baboons,
