Wildlife Letters, EarlyView.Common cuckoo nestlings from different populations show varying degrees of mimicry of warbler begging calls, with the Yongnianwa population being the most accurate and the Zhalong population the least. Overall, these cuckoos employ a dual strategy: they conservatively mimic the high‐frequency components of host calls while adaptively adjusting their ...

QSAR studies on indazolyl urea TRPV1 channel antagonists(吲唑脲类辣椒素受体通道拮抗剂的定量构效关系)
Zhejiang Daxue xuebao. Lixue ban, 2010 研究了吲唑脲类辣椒素受体(TRPV1)通道拮抗剂的定量构效关系(QSAR).首先,采用1H-吲唑异构形式,对27个TRPV1通道拮抗剂分子进行了HF/6-31G*水平上的结构优化,在优化结构上进行了5类拓扑指数和分子静电势及其导出参数的计算.运用多元线性回归方法对这些化合物的生物活性与其分子结构参数进行了关联.对所有化合物采用另一异构形式重复上述过程,以探讨互变异构对QSAR建模的影响.结果表明：互变异构对QSAR结果具有一定的影响,采用1H-吲唑异构形式得到的模型,在质量上均高于采用2H-吲唑异构体 ...

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 ...

Methodology to identify ecologically matching areas and its applications in conservation planning
Conservation Biology, EarlyView.Abstract Identifying ecologically matching areas is both challenging and critical for understanding spatial patterns of biodiversity and advancing conservation planning. However, existing approaches often lack spatial flexibility, overlook shape and size constraints, or rely on limited environmental parameters, reducing their effectiveness in real ...

Integrating biodiversity protection into emergency management
Conservation Biology, EarlyView.Abstract Megafires have emerged as a considerable threat to biodiversity conservation worldwide. The biodiversity‐focused response and recovery actions that occurred during Australia's 2019/2020 Black Summer bushfires demonstrate that it is possible to protect biodiversity alongside human life and property during disasters.

Zhejiang Daxue xuebao. Lixue ban, 2005 利用多元线性回归和偏最小二乘分析方法，研究分子表面静电势参数，VolSurf参数与双十四酰基磷脂酰基胆碱(DMPC)-水分配系数之间的定量结构-性质关系(QSPR)，均得到较好的结果.分子表面静电势参数分析表明化合物分子表面上负的静电势越分散，越倾向于分配在水相中；与水分子的作用越强，越有利于分配在水相中.此外，具有较大体积和偶极密度的分子倾向于分配在弱极性相中.VolSurf参数分析表明大体积的分子易于分配在DMPC中;分子表面亲水区域较大的分子则倾向于分配在水相中 ...
