Optimizing biodiversity offsetting for habitat succession and colonization dynamics
Abstract Biodiversity offsetting aims to compensate for ecological losses from development through conservation and restoration. However, its long‐term outcomes under repeated impact–offset cycles remain uncertain. Using a conceptual forest succession model, we evaluated how offset outcomes are affected by interactions among compensation scale ...

【目的】为了探讨tau基因多态性与帕金森病的关系。【方法】本实验用PCR-片段长度多态性分析法检测了123例中国散发性帕金森病病人和114个正常对照的微管相关蛋白(tau)基因A0等位基因多态性。【结果】我们发现tau基因A0等位基因和A0/A0基因型在帕金森病组的出现率略高于对照组,分别为77.6%:74.1%和61%:57%,但无统计学意义。【结论】A0多态性与我国散发性帕金森病发病无关。

How endorser attributes influence conservation communication
Abstract Conservation communication often uses the celebrity endorsement strategy. However, robust evidence regarding its effectiveness is still limited. More importantly, practitioners do not have guidelines for selecting an ideal endorser because there is no clear consensus on what endorser attributes are most critical.

近年来,生物多样性监测网络的建设得到广泛重视,全球、地区或国家生物多样性观测网不断组建。生物多样性观测的理论框架得到发展,提出了生物多样性核心监测指标(Essential Biodiversity Variables,EBV)。鱼类多样性监测的理论框架包含于生物多样性核心监测指标之内,在遗传、物种、生态系统等多层次进行。基于鱼类监测提出的生物完整性指数(index of biotic integrity,IBI)强调不同物种的生态功能,可以综合反映群落结构和功能的变化,得到广泛应用 ...

目的探讨吉林地区汉族人群脂联素基因(apM1)多态性与与冠心病的关系。方法运用单核苷酸多态性分析技术在251例无亲缘关系的吉林地区汉族人群(正常对照人群131例,冠心病120例)中检测apM1基因2号外显子及3号外显子的多态性。结果吉林地区汉族人群中SNP45(T/G)和SNP331(T/C)多态性的基因型频率和等位基因频率在冠心病组和正常对照组间的分布存在显著性差异 ...

Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study
ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.

用RAPD技术对稀有Ju鲫近交10代及3个野生群体的遗传多样性和群体间差异进行了研究。无论从多态位点的比例,个体间的共带率还是多样性指数来看,近交10代的遗传多样性极低。在226个RAPD位点中,野生群体有近半数的位点是多态的,Shannon多样性指数在0.2911-0.3235间,表明自群本保持了较丰富遗传多样性。近交10代与野生群体间遗传差异十分明显。野生群体间在11 ...
