项目摘要
In recent years, evidence has grown that the migratory behaviour of many bird species is changing in response to changing environmental conditions. In particular, non-migratory individuals have been reported in previously wholly migratory populations. These rapid changes in migratory behaviour provide an opportunity to understand the ontogeny of migratory behaviour and identify the mechanisms through which complex and highly evolved behaviours respond to changing environmental conditions. Changes in environmental conditions and in resource availability can alter the selection pressures operating on migratory behaviour, and individual strategies may differ according to the conditions individuals will experience. Long-lived birds may experience considerable changes in environment and resource availability during their life-time, hence it would be advantageous for individuals to be flexible and adopt the migratory strategy that best takes advantage of changing environmental conditions. This has rarely been observed and individuals tend to be consistent in the migratory strategy they adopt in early life. This project will examine the environmental conditions that determine the establishment of different individual migratory strategies. Individual level data is difficult to obtain since the environmental data is not available at the scale individuals experience it. This project will involve tracking white storks (large, long-lived birds) and simultaneously monitoring the environmental conditions which individual birds experience. Our current GPS/GSM loggers can record accelerometer and temperature data but new sensors are needed to monitor other environmental parameters that may affect dispersal and movement (wind speed, direction, humidity). We will monitor how changes in environmental conditions will affect the movement, migratory behaviour and mortality of resident and migratory white storks. Methods:This project will benefit from the experience of previous work done with tracking white storks in Portugal and Spain and will be linked to an existing NERC POC for the development of new tracking devices to monitor the movement behavior of animals.White storks are a good study system because they are large long-lived species likely to have adaptable behaviour because they experience variation in environmental conditions through their lives. We will track the movement of 40 juveniles and 20 adults and their movement in response to changes in environmental conditions. The birds will be trapped at the nest, their fitness, sex and age will be recorded. Movement characteristics (speed, direction, flight type and distance moved) will be related to the data obtained by the environmental sensors on the tracking devices and to ground cover on the locations where birds land.Objectives:- Identify the environmental determinants of dispersal and migratory behaviour, controlling for individual fitness, age and sex;- Incorporate new sensors in existing dataloggers and create new prototypes that simultaneous monitor bird movement (GPS), behavior (accelerometer) and environmental parameters (e.g. temperature, wind speed, barometer)- Determine the influence of environmental parameters in the demography of white storks including migration and over-winter survival, arrival date, nest-site selection, and breeding success.
近年来,越来越多的证据表明,许多鸟类的迁徙行为正在随着环境条件的变化而改变。特别是,据报告,在以前完全移徙的人口中也有非移徙者。迁徙行为的这些迅速变化为了解迁徙行为的个体发生和确定复杂和高度进化的行为对不断变化的环境条件作出反应的机制提供了机会。环境条件和资源可得性的变化可以改变对移徙行为起作用的选择压力,而个人的战略可能因个人将经历的条件而异。长寿鸟类在其一生中可能会经历环境和资源可用性的巨大变化,因此,个体灵活并采取最佳利用变化的环境条件的迁移策略将是有利的。这种情况很少被观察到,个人在早年采取的移徙战略往往是一致的。该项目将研究决定制定不同的个人移徙战略的环境条件。由于无法获得个体经历的环境数据,因此难以获得个体水平的数据,该项目将涉及跟踪白色鹳(大型长寿鸟类),同时监测个体鸟类经历的环境条件。我们目前的GPS/GSM记录仪可以记录加速度计和温度数据,但需要新的传感器来监测可能影响扩散和移动的其他环境参数(风速,方向,湿度)。我们将监测环境条件的变化将如何影响定居和迁徙白色鹳的运动、迁徙行为和死亡率。方法:该项目将受益于以前的工作经验,跟踪白色鹳在葡萄牙和西班牙,并将与现有的NERC POC的新的跟踪设备的发展,以监测动物的运动behaviors.白色鹳是一个很好的研究系统,因为他们是大的长寿物种可能有适应性的行为,因为他们经历的变化,在环境条件下,通过他们的生活。我们将跟踪40名青少年和20名成年人的运动,以及他们对环境条件变化的反应。这些鸟将被困在巢中,它们的健康,性别和年龄将被记录。移动特性(速度、方向、飞行类型和移动的距离)将与跟踪设备上的环境传感器获得的数据和鸟类着陆地点的地面覆盖物相关。目标:-确定扩散和迁移行为的环境决定因素,控制个体健康、年龄和性别;- 在现有数据记录器中集成新传感器并创建可同时监测鸟类运动(GPS)的新原型,行为(加速计)和环境参数(如温度、风速、气压计)-确定环境参数对白色白鹳种群的影响,包括迁徙和越冬存活、到达日期、巢址选择和繁殖成功率。
