胶囊无线电跟踪和遥感显示沼泽山雀选择英国橡树栎robur树木在大的冬季home-range.Aims调查冬季栖息地选择沼泽山雀在英国的木材，测试的喜好，树种和林地structure.Methods十三沼泽山雀在冬季进行无线电跟踪，和家庭范围的推导。激光雷达和高光谱数据被用来比较整个活动范围和密集使用核心地区的植被结构和树种组成。瞬时取样观测为树种利用提供了进一步的信息。结果平均家域很大（39公顷，n = 13）。有没有显着差异，平均树高，郁闭度，林下高度，或灌木量之间的完整的家庭范围和核心领域的使用。核心地区包含了显着更大比例的英国橡树相对于可用性在整个家庭范围。瞬时采样证实，英国橡树使用显着超过其他trees.Conclusion选择英国橡树在冬季与以前的研究相比，繁殖领土，表明栖息地的使用季节性变化，并证明全年的栖息地选择研究的必要性。大的家庭范围有助于解释沼泽山雀的栖息地破碎化的敏感性。
Capsule Radio-tracking and remote sensing showed Marsh Tits selected for English Oak Quercus robur trees within large winter home-ranges.Aims To investigate winter habitat selection by Marsh Tits in a British wood, testing for preferences in tree species and woodland structure.Methods Thirteen Marsh Tits were radio-tracked during the winter, and home-ranges were derived. Lidar and hyperspectral data were used to compare the vegetation structure and tree species composition of entire home-ranges and the core areas of intensive use within. Instantaneous sampling observations provided further information for tree species utilization.Results The mean home-range was very large (39 ha, n = 13). There were no significant differences in mean tree height, canopy closure, understorey height, or shrub volume between full home-ranges and the core areas of use. Core areas contained a significantly greater proportion of English Oak relative to availability in the full home-ranges. Instantaneous sampling confirmed that English Oak was used significantly more than other trees.Conclusion Selection for English Oak during winter contrasted with previous studies of breeding territories, indicating that habitat usage varies seasonally and demonstrating the need for habitat selection studies throughout the year. Large home-ranges help to explain the Marsh Tit's sensitivity to habitat fragmentation.
