Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Influence of reclamation on tide processes in Eastern China Seas [PDF]
, 2016 摘要 本研究基于区域海洋模式（RegionalOceanModelingSystem）建立了东中国海二维潮汐水动力模型。利用该模型结果讨论了渤、黄、东海的水动力特征及苏北沿岸围填海对其水动力环境的影响。最后对南黄海无潮点的移动与韩国西岸潮振幅的变化的关系进行了探讨。 水动力模型结果与中国沿岸验潮站观测数据比较显示，M2、S2、K1、O1四个主要分潮振幅和迟角的均方根误差分别为10cm和33.2°、6.2cm和34.5°、8.8cm和29.4°、6.0cm和40.6°。比较结果表明 ...

野生动物学报, 2023 自20世纪90年代，开始了中国中缅树鼩（Tupaia belangeri）的生理生态学研究。回顾30年来中国中缅树鼩生理生态学的研究与发展：起源和分类、能量代谢和产热特征、脂肪组织、形态学、组学、化学通讯和行为学等。在科学发展的新时期，除进一步加强有关中缅树鼩对极端环境的生理适应研究外，还需要借助多组学、遥感与红外技术等，加强对动物生理适应的分子水平的机理性探究。结合全球温室效应的环境背景，从地理分布北线、食性、肠道微生物多样性以及实验动物建模等方面对中缅树鼩未来的研究方向进行了展望。

Conservation Biology, EarlyView.Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...
