, 2016 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 ...

Psychometric framework for coexistence with large carnivores
Conservation Biology, EarlyView.Abstract Human–carnivore coexistence is essential for biodiversity conservation, yet measuring the attitudes and behaviors that support it remains methodologically challenging. We developed psychometric scales to assess willingness to coexist with carnivores and the underlying beliefs of this coexistence through an iterative expert elicitation process ...

There Is Always a Bigger Fish. Determinants of Power Perceptions in Swiss Biodiversity Policy
Policy Studies Journal, EarlyView.ABSTRACT The Advocacy Coalition Framework (ACF) views power as crucial in policy processes, but the nature of coalition power, its determinants, and how to empirically measure it remain understudied. In this article, we use a mixed method approach and social network analysis to explore power relationships in the biodiversity policy subsystem in ...

Shuitu Baochi Xuebao, 2008 2003—2004年开展对9个有代表性的不同产量的苹果园秋季土壤的养分、微生物类群及土壤酶活性的研究,获得不同产量苹果园的土壤微生物生态状况。结果表明,各苹果园的土壤养分、微生物数量、多样性和酶活性均表现出较大差异。随土壤碱解氮、速效磷、速效钾、总碳含量的增加,产量水平呈增高趋势。高产园土壤微生物数量高,多数土壤酶活性强,微生物多样性好。土壤微生物中细菌数量、微生物多样性、蛋白酶、磷酸酶活性可作为评价果园土壤肥力的生物指标。果树产量与土壤微生物类群和数量具有显著正相关,与速效磷、速效钾 ...

Resource Substitution: Local Governments' Issue Attention and Policy Reinvention
Policy Studies Journal, EarlyView.ABSTRACT Research on policy reinvention, where a government modifies rather than replicates policy innovations introduced by other governments, has progressed significantly, but how it is influenced by the government's issue attention has not been thoroughly examined.
