Lucy J. Ryan, Auteur ; Jonathan A. Green, Auteur ; Stephen G. Dodd, AuteurCapsule Inter-annual survival rates of juvenile Dunlin Calidris alpina increased with wet weather conditions but decreased with the density of conspecifics in winter, ranging from 0.34 to 0.62 in the best model. Adult inter-annual survival remai[...]

Craig R. White, Auteur ; David Boertmann, Auteur ; David Grémillet, Auteur ; Patrick J. Butler, Auteur ; Jonathan A. Green, Auteur ; Graham R. Martin, AuteurArctic seas have warmed and sea ice has retreated. This has resulted in range contraction and population declines in some species, but it could potentially be a boon for others. Great Cormorants Phalacrocorax carbo have a partially wettable plum[...]
