Patch occupancy in Coenonympha tullia (Muller, 1764) (Lepidoptera: Satyrinae): habitat quality matters as much as patch size and isolation

摘要: Patch occupancy by Coenonympha tullia has been surveyed in 166 sites Northumberland, UK. It was found 117 of them and absent 37. Weather conditions were too poor to determine its presence at a further 12 sites. Differences habitat quality among account for patch as successfully (R2 = 48%) isolation size jointly 46%). This finding relevance metapopulation studies it demonstrates that greater attention should be given differences patches beyond their distance from one another. Together, quality, 61% the variation C. discriminant analysis produces correct classification > 88% Habitat much same variance, result twelve excluded analysis, they do conjunction with isolation. suggests there is potential predicting changes site specific data face biotopes, such planned exploitation deterioration other causes including climate change management practices.
