Preliminary evaluation of establishment for bioscreening plant growth regulators(植物生长调节剂生物筛选方法的初步构建)
Zhejiang Daxue xuebao. Lixue ban, 2002 通过对13种植物生长调节剂的试验,建立了用于筛选植物生长调节剂的生物检测方法.该方法第1步采用萝卜、黄瓜、小麦、油菜4种幼苗生长法联合筛选,第2步采用萝卜子叶扩张法、黄瓜子叶生根法联合筛选,这样能保证有生长调节剂活性的化合物在普筛中不被漏筛,而且方法简便,测试周期短.

Conservation Biology, EarlyView.Abstract Modeling species distributions in dynamic pelagic environments remains challenging, particularly for wide‐ranging and highly mobile species when there is limited guidance on model performance. This limitation constrains the effective use of species distribution models (SDMs) in marine conservation, where robust and transferable predictions are

野生动物学报, 2007 野生动物所有权在野生动物保护事业中具有十分重要的地位,为此,我国先后制定了多部与野生动物所有权有关的法律法规,将野生动物所有权纳入法律调整的范围。但是受制定法律法规时各种条件的限制,目前我国野生动物所有权立法存在着一些不尽合理的地方,本文通过对我国野生动物所有权规范性法律文件的梳理,分析了立法方面存在的不足,并提出了立法建议。

Conservation Biology, EarlyView.Abstract Adaptive management of threatened species relies on having ex ante estimates of species’ responses to different interventions. Structured expert elicitation is often used to generate these estimates, but comparisons of these expert‐predicted outcomes with observed results are rare.

Structured decision‐making as a framework to incorporate social equity into conservation decisions
Conservation Biology, EarlyView.Abstract Many conservation challenges require negotiating trade‐offs between the needs of different actors. Global frameworks such as the Kunming–Montreal Global Biodiversity Framework explicitly call for diverse participation and social equity in conservation decision‐making.
