| mechanisms driving galling success in a fragmented landscape: synergy of habitat and top-down factors along temperate forest edges. | edge effects play key roles in the anthropogenic transformation of forested ecosystems and their biota, and are therefore a prime field of contemporary fragmentation research. we present the first empirical study to address edge effects on the population level of a widespread galling herbivore in a temperate deciduous forest. by analyzing edge effects on abundance and trophic interactions of beech gall midge (mikiola fagi htg.), we found 30% higher gall abundance in the edge habitat as well as l ... | 2016 | 27310599 |
