Matthieu Guillemain, Auteur ; Jocelyn Champagnon, Auteur ; Gregoire Massez, Auteur ; Claire Agnès Pernollet, Auteur ; Thierry George, Auteur ; Andre Momerency, Auteur ; Géraldine Simon, AuteurDans Wildfowl (65 2015)Earlier studies from central and northern Europe have found a shortening of the ring recovery distance in Mallard Anas platyrhynchos, which was generally attributed to climate change leading to a northwards shift of the wintering range. Here we [...]

Matthieu Guillemain, Auteur ; Olivier Devineau, Auteur ; Michel Gauthier-Clerc, Auteur ; Richard Hearn, Auteur ; Roy King, Auteur ; Géraldine Simon, Auteur ; Mark Grantham, AuteurAlthough knowledge of ring recovery rate is of crucial importance to establish demographic parameters, such as survival probability, this information is generally unknown for the dabbling ducks. The almost single existing value from the North Am[...]

Matthieu Guillemain, Auteur ; Johan Elmberg, Auteur ; Michel Gauthier-Clerc, Auteur ; Gregoire Massez, Auteur ; Richard Hearn, Auteur ; Jocelyn Champagnon, Auteur ; Géraldine Simon, AuteurAnimal populations are exposed to large-scale anthropogenic impact from e.g. climate change, habitat alteration and supplemental stocking. All of these may affect body condition in wintering dabbling ducks, which in turn may affect an individual[...]
Article
Matthieu Guillemain, Auteur ; Olivier Devineau, Auteur ; Géraldine Simon, Auteur ; Michel Gauthier-Clerc, AuteurRallidae are common and widespread, yet relatively poorly studied. We analysed the ringing data from more than 8,000 Common Coot Fulica atra, accumulated between 1950 and 1982 in Camargue, southern France, in terms of the dynamics of their biome[...]
Article
Matthieu Guillemain, Auteur ; Richard Hearn, Auteur ; Roy King, Auteur ; Michel Gauthier-Clerc, Auteur ; Géraldine Simon, Auteur ; Alain Caizergues, AuteurThe "body size hypothesis" predicts that if individuals of a population migrate different distances from the breeding to the wintering grounds, the distance should be related to the differential ability to cope with adverse conditions, with larg[...]
Article
Matthieu Guillemain, Auteur ; Andy J. Green, Auteur ; Géraldine Simon, Auteur ; Michel Gauthier-Clerc, AuteurFew studies have considered how body condition changes over time in individual birds, and most of these concerned long-lived breeding birds. We used a large database of Common Teal Anas crecca ringed and recaptured while wintering in the Camargu[...]
Article
Matthieu Guillemain, Auteur ; Olivier Devineau, Auteur ; Jean-Dominique Lebreton, Auteur ; Jean-Yves Mondain-Monval, Auteur ; Alan R. Johnson, Auteur ; Géraldine Simon, AuteurThe negative consequences of lead shot ingestion have been demonstrated in captive birds, and the prevalence of embedded shot has been measured in wild waterfowl several times. However, the long-term consequences of these two indirect outcomes o[...]
Article
Clément Calenge, Auteur ; Matthieu Guillemain, Auteur ; Michel Gauthier-Clerc, Auteur ; Géraldine Simon, AuteurWe use a new method called "product kernel estimator" to explore the spatial and temporal distribution of 9,114 recoveries of Teal (Anas crecca) ringed in Camargue, southern France, and recovered over the whole of Europe. This method allows expl[...]
