项目摘要
Breeding areas for resident and migrant birds in North America are becoming increasingly fragmented by human use and birds must also cope with changing climate. Climate warming is predicted to be most intense at high latitudes, hence, boreal birds may be most affected. Since forest microclimate is affected by patch size and surrounding forest cover, harsher weather conditions and lower amounts insect food in smaller patches may reduce survival of winter residents. However, in spring, fragments may warm up earlier, have earlier plant and insect phenology and more insects, hence medium sized patches may be of high quality in spring and summer. These interactions between fragmentation, weather and microclimate and phenology and the impacts of these on population persistence in fragmented landscapes have not been well studied. The main objectives of this proposal are to: 1. Determine the influence of patch size and surrounding forest cover on micro-climate, plant phenology, insect phenology and abundance in winter and summer. 2. Relate these factors to winter survival and body condition and to breeding season food conditions and reproductive success of resident birds (chickadees, nuthatches, woodpeckers). 3. Relate these factors to arrival times, territory choice and reproductive success of migrants. 4. Determine the relationship of spring temperature and extreme weather events on sex and age ratios of migrant birds arriving at banding stations in the northern parts of the breeding range.
由于人类活动的影响,北美留鸟和候鸟的繁殖地变得越来越分散,鸟类也必须应对气候变化。据预测,气候变暖在高纬度地区最为强烈,因此北方鸟类可能受到最大的影响。由于森林小气候受斑块大小和周围森林覆盖的影响,恶劣的天气条件和较小斑块中较低数量的昆虫食物可能会减少冬季居民的生存。然而,在春季,碎片可能会更早变暖,植物和昆虫物候期更早,昆虫更多,因此,中等大小的斑块在春季和夏季可能是高质量的。破碎化,天气和小气候和物候之间的相互作用,以及这些对破碎化景观中种群持续性的影响尚未得到很好的研究。确定斑块大小和周围森林覆盖对小气候、植物物候、昆虫物候和冬夏丰富度的影响。2.将这些因素与冬季生存和身体状况以及繁殖季节食物条件和常驻鸟类(山雀,nuthatches,啄木鸟)的繁殖成功联系起来。3.将这些因素与移徙者的抵达时间、领土选择和生殖成功联系起来。4.确定春季温度和极端天气事件对到达繁殖范围北方部分环志站的候鸟性别和年龄比的关系。
