21世纪外来生物入侵物种造成的全球威胁以及国家的应对能力

Posted on 星期三, 24 八月 2016, 11:26

外来入侵物种威胁到了人类生产生活和全球生态安全。快速发展的全球化进程有利于外来入侵物种的传播和环境的改变,其中包括了气候变化有利于外来入侵物种的定殖。这里我们首次提供了全球化的、从21世纪全球化和环境变化的观点上对于来自外来入侵生物的威胁进行的空间分析,以及对于国家阻止和管理外来入侵生物的能力方面进行的评估。我们发现全球六分之一的地表对于外来生物入侵的抵抗力十分脆弱,这包括了发展中经济体和生物多样性热点地区。主要生物入侵的原因在不同的国家之间是不同的,高收入国家主要是由于进口尤其是进口植物和动物,低收入国家则主要是由于空中交通等因素。综合入侵和定殖的相关数据可以提升早期预警和铲除规划的效果。大多数国家是没有能力抵抗外来入侵物种的。尤其是,那些极端贫穷、高生物多样性以及低生物入侵历史的地区更是急需前瞻性的生物入侵防控策略。

面对和管理来自一种严重威胁环境和水体的外来入侵生物-水葫芦(凤眼莲,Eichhornia crassipes)现在和未来的有害生物风险

Posted on 星期二, 23 八月 2016, 15:11

理解和管理现在和未来气候条件下由水生植物造成的生物入侵的威胁是对于全球范围内生物安全和土地管理机构的极大的挑战。水葫芦(凤眼莲,Eichhornia crassipes)是世界上影响最坏的水生植物。现今严重威胁到水生生态系统,并且严重削弱了发达及发展中国家对于淡水供应和管理。

大部分国家缺少应对外来入侵生物的能力

Posted on 星期二, 23 八月 2016, 15:07

一项研究表明,世界上大部分国家缺乏应对外来入侵生物的有效措施。非本地生物的传播蔓延严重影响到了生产生活和生物多样性,并且这一态势由于全球贸易、旅行和气候变化变得更加糟糕。他们表明了地球土表面积的六分之一以上易受到有害生物的侵害。其中作者还表明了这是关于个体国家管理入侵生物和应对新传入入侵生物能力第一份相关报道。 获取更多

国际植保公约召开关于入侵性有害生物的研讨会,主题是:入侵模式与趋势动态、对全球的影响和可采取的对策

Posted on 星期二, 29 九月 2015, 18:36

2015年9月24日,国际植保公约在联合国粮农组织总部召开关于入侵性有害生物的研讨会,主题是:入侵模式与趋势动态、对全球的影响和可采取的对策。入侵生物专家小组主席皮耶罗杰诺韦西博士,受邀在研讨会上授课。国际植保公约秘书处夏敬源博士主持研讨会,来自但不局限于渔业司、水土司、食品安全司和森林司等不同的粮农组织部门的60多人参加了研讨会。尊敬的法国大使托马斯先生和中国常驻联合国粮农组织代表处的相关人员也参与了研讨会。

杰诺韦西博士在他的报告中介绍了基于最新科学研究成果的在全球层面的入侵性有害生物的入侵、定殖和传播的主要模式,从而说明了整个入侵性有害生物的全球趋势动态。研讨会清晰的揭示了入侵性有害生物是如何影响农业、畜牧业、渔业、森林、水土和人类赖以生存的环境的,例如入侵非洲和亚洲的入侵性有害生物-水葫芦,它们污染了水源、阻塞了水上交通、影响了渔业,减少了水源从而助长了疟疾的流行。其他的例子很多是关于入侵性有害生物对于全球生物多样性的影响的,如北美蚯蚓的入侵、剑叶花属冰草植物在欧洲的入侵、牧豆树属在非洲的入侵以及食肉动物对于岛屿的影响等。

所有的这些负面...

IYOBThe final and most controversial product adopted at the two-week long 10th Conference of Parties of the Convention on Biodiversity was the Nagoya Protocol on "Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization". The Nagoya Protocol sets terms on how countries will permit access to genetic resources, share the benefits arising from their use, and cooperate with one another in allegations of misuse. It will come into force 90 days af...
