The last month has seen a fantastic diversity of images added to our site, including the evocative work of Sandra Bartocha and Werner Bollmann, capturing the light of the Nordic world, Laurie Campbell's Scottish wildilfe and plants, poisonous sea snakes and tree kangaroos from Jurgen Freund, Cyril Ruoso's Namib Desert wild horses, and bold invertebrates from Emmanuele Biggi, Edwiin Giesbers and Robert Thompson, Staffan Widstrand's coverage from New Guinea, Eladio Fernandez's material from Cuba and Haiti, Phil Savoie's Costa Rican wildlife, and a strong range of environmental subjects from specialist Ashley Cooper, plus an engaging set of images on the Thames "swan-upping" tradition.
