无人机遥感调查黄河源玛多县岩羊数量及分布

本研究于2017年利用无人机航拍调查对黄河源玛多县县域内的岩羊种群数量进行了估算,并对其分布规律进行了研究。无人机航拍共获取影像23784张,有效面积326.6 km~2,通过目视解译,获取样带内的岩羊种群数量为203只,种群密度为0.6215只/km~2。通过推算,得到玛多县岩羊种群数量为8968只。对玛多县岩羊分布位置与环境因子的分析结果显示:岩羊偏好于选择海拔为4100～4200 m、距公路大于3 km、距悬崖峭壁200 m以内的区域活动。本研究利用无人机航拍样带调查估算黄河源玛多县岩羊种群数量与密度,并结合ArcGIS软件对其生境进行分析,将3S技术与野生动物调查相结合,为青藏高原地区大型野生动物相关研究提供了新思路。

Paying for information: partial loads in central place foragers

Information about food sources can be crucial to the success of a foraging animal. We predict that this will influence foraging decisions by group-living foragers, which may sacrifice short-term foraging efficiency to collect information more frequently. This result emerges from a model of a central-place forager that can potentially receive information on newly available superior food sources at the central place. Such foragers are expected to return early from food sources, even with just partial loads, if information about the presence of sufficiently valuable food sources is likely to become available. Returning with an incomplete load implies that the forager is at that point not achieving the maximum possible food delivery rate. However, such partial loading can be more than compensated for by an earlier exploitation of a superior food source. Our model does not assume cooperative foraging and could thus be used to investigate this effect for any social central-place forager. We illustrate the approach using numerical calculations for honeybees and leafcutter ants, which do forage cooperatively. For these examples, however, our results indicate that reducing load confers minimal benefits in terms of receiving information. Moreover, the hypothesis that foragers reduce load to give information more quickly (rather than to receive it) fits empirical data from social insects better. Thus, we can conclude that in these two cases of social-insect foraging, efficient distribution of information by successful foragers may be more important than efficient collection of information by unsuccessful ones.     

Green payments and dual policy goals

We use a mechanism design framework to analyze the optimal design of green payment policies with the dual goals of conservation and income support for small farms. Each farm is characterized by two dimensions of attributes: farms size and conservation efficiency. The policymaker may not be able to use the attributes as an explicit criterion for payments. We characterize optimal policy when conservation efficiency is unobservable to policymakers, and when farm size is also unobservable. An income support goal is shown to reduce the conservation distortion caused by asymmetric information. The cost of optimal green payment mechanisms is shown to depend crucially on whether large or small farms have greater conservation efficiency.
