Publications Mes premières implications dans l’étude des serpents débutent très tôt dans mon cursus Universitaire (1996, stage de DEUG). Dès mon entrée en DEA à Chizé (1998) j’ai pu commencer à me consacrer au travail de publication. Ma position d’auteur associé dans ces travaux publiés trouve ainsi son origine dans une participation active de ma part à la fois dans la récolte des données, les analyses statistiques et la rédaction. Par la suite, je me suis impliqué de façon plus personnalisée avec la publication de quatre articles dont je suis l’auteur principal. Liste des publications sur la thèmatique de thèse : 1. Lourdais O, Bonnet X, DeNardo D, Naulleau G. (2002) Does sex differences in reproductive eco-physiology translate in different demographic patterns ? Population Ecology, in press 2. Lourdais O, Bonnet X, Shine R & Taylor E. (2002) When does a reproducing female viper (Vipera aspis) "decide" on her litter size? Journal of Zoology, London in press 3. Lourdais O, Bonnet X, Shine R , DeNardo D, Naulleau G & Guillon M. (2002). Capital-breeding and reproductive effort in a variable environment: a longitudinal study of a viviparous snake. Journal of Animal Ecology 71 : 470-479. 4. Lourdais O, Bonnet X, Doughty P. (2002). Costs of anorexia during pregnancy in a viviparous snake (Vipera aspis). Journal of Experimental Zoology 292 : 487- 493. 6
5. Bonnet X, Lourdais O, Shine R. & Guy Naulleau. (2002). Reproduction in a typical capital breeder : costs, currencies and complications in the aspic viper Ecology 83 : 2124-2135. 6. Bonnet X., Naulleau G. & Lourdais O. (2002). The benefits of complementary techniques: using capture-recapture and physiological approaches to understand costs of reproduction in the asp viper. Biology of the Vipers, in press 7. Bonnet X., Shine R, Lourdais O & Naulleau G (2002) Measures of reproductive allometry are sensitive to sampling Bias. Functionnal Ecology, in press 8. Aubret F, Bonnet X, Shine R & Lourdais O. (2002) Fat is sexy for females but not males: the influence of body reserves on reproduction in snakes (Vipera aspis). Hormones and Behaviors 42 : 135-147. 9. Bonnet X., Naulleau G., Shine R. & Lourdais O. (2001). Short-term versus long- term effects of food intake on reproductive output in a viviparous snake (Vipera aspis). Oikos 92 : 297-308. 10. Bonnet X., Naulleau G., Shine R. & Lourdais O. (2000). What is the appropriate time scale for measuring costs of reproduction in a capital breeder? Evolutionary Ecology 13 : 485-497. 11. Bonnet X., Naulleau G., Shine R. & Lourdais O. (2000). Reproductive versus ecological advantages to larger body size in female Vipera aspis. Oikos 89 : 509- 518. 12. Naulleau G., Bonnet X., Vacher-Vallas M, Shine R. & Lourdais O. (1999). Does less-than-annual production of offspring by female vipers (Vipera aspis) mean less-than-annual mating? Journal of Herpetology 33 : 688-691. 7
