Contribution of microcosm experiments to conservation science

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Microcosms, or miniature experimental systems, have been used to develop models and theories in ecology. However, their contribution to conservation science is unclear. We explored the application, design, and impact of microcosms in conservation science from 469 systematically identified articles published from 1986 to 2023.

成都市中小学保护教育现状调查

open access: yes野生动物学报, 2014
为探索成都动物园未来保护教育工作的发展方向和路线,在成都对4所中小学中年龄在6~14岁的339名学生进行了问卷调查。问卷调查了学生在保护教育态度、环境信息获得以及关注动物园等几个方面的情况。并提出发展当地环境保护教育的3点建议:(1)教育政策对于环境保护的引导,让保护教育成为素质教育的必修课;(2)保护教育专业队伍的建立与发展;(3)联合学校开发适应地方性特色的环境保护教育学校教材。

Applying Environmental Kuznets Curve to EIA on an Industrial Park Planning [PDF]

open access: yes, 2008
以可持续发展为目标的规划环评要求对规划区域的社会经济与环境状况的相关性进行分析。文章引进了环境库兹涅茨曲线(EKC),用于福建省某一石化工业基地的规划环评中的经济发展与环境保护协调性分析,研究了当地经济与工业废物排放的耦合程度,丰富了规划环评的方法。This paper introduces the Environmental Kuznets Curve as a tool to analyze the correlation between social economy and ...

Understandings and critiques of biocultural diversity conservation and future recommendations for conservation actors

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract As biocultural approaches to conservation gain traction (e.g., through international commitments to Indigenous Peoples and local communities) and external conservation actors increasingly seek to engage with on‐the‐ground holders of biocultural diversity, improved understanding is needed of what biocultural diversity means.

全国公众对蛇类资源保护态度的调查

open access: yes野生动物学报, 2006
中国野生动物保护协会于2002年5月至7月,提出了有关蛇类资源保护的10个问题,组织在全国35个大中城市开展了蛇类资源保护公众态度的问卷调查,调查结果表明:在华南等地吃蛇明显高于其它地区;营养、滋补是人们食用蛇类的主要动机;在目前的营养条件下没有必要吃蛇;多数公众对野外蛇的生存状况、人工养殖的情况不了解,对市场上蛇的来源不清楚;吃蛇或使用蛇产品会对生态环境造成破坏,适量用于医药、禁止食用是公众对蛇类保护的基本态度;应该保护蛇类是广大公众的主流民意;对《野生动物保护法》有较高的认知度 ...

面向业务感知的共享链路保护策略研究

open access: yesGuangtongxin yanjiu, 2021
针对传统弹性光网络采用专用路径1+1保护策略存在资源浪费的问题,文章提出了一种共享链路保护策略。在检测到链路故障后,柔性光转发器切换至共享保护链路,并根据业务的优先级和请求频率重排业务权重,依据业务权重提供差异化的路由和频谱分配。此外,文章提出一种以物理网络拓扑结构、业务需求集合和优质业务量占比为约束条件,以最小化频谱隙利用率为目标,具有业务区分的路由和频谱分配方法。理论分析和仿真结果表明,与传统的1+1保护方法相比,所提保护策略在降低网络拥塞率的同时,可以最多节省38%的频谱资源 ...

Ecotoxicological Effects of Lead and Copper on Seed Germination of Wheat [PDF]

open access: yes, 2009
通过种子萌发试验,研究了不同浓度的Pb2+和Cu2+对小麦种子萌发、幼苗生长以及对小麦α-淀粉酶活性的生态毒理效应。结果表明:Pb2+在低浓度下(5Mg·l-1)对小麦种子萌发过程中的各项指标皆为抑制作用;Pb2+、Cu2+胁迫对小麦α-淀粉酶活性存在低浓度激活和高浓度抑制的效应,且浓度越高,抑制作用越强;Cu2+对小麦种子萌发各项指标的抑制率大于Pb2+,Pb2+、Cu2+对小麦根生长的毒害作用大于对地上部的影响。By seed germination experiments, We studied ...

Mitigating light pollution impacts on arthropods based on light‐emitting diode properties

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Light pollution from artificial light at night (ALAN) is a significant environmental problem with far‐reaching consequences for ecological systems. Recent innovations in light‐emitting diode (LED) technology may offer sustainable outdoor lighting solutions, but scientific evidence is lacking. We investigated the effects of various LED lighting
