The settlement of the Queensland farm that tested positive for Panama Disease Tropical race 4 (TR4) will now proceed, following the confirmation that a suspect plant from a nearby property does not contain the disease. The planned buyout of the TR4 farm, owned by the Robson family, was temporarily suspended late last month after the suspect plant was reported to Biosecurity Queensland (BQ).

Alien fungus blights Hawaii's native trees

Posted on 星期二, 25 十月 2016, 08:20

An ecological disaster is unfolding on Hawaii's largest island. Rapid 'Ôhi'a Death, caused by an imported fungus, is causing Hawaii's iconic native 'ôhi'a tree to perish in droves. Some 20,000 hectares are now affected, according to a recent survey. Abundant across the archipelago, 'ôhi'a are the only native tree in Hawaii that colonizes lava flows, and they provide habitat for several rare species of native birds and insects. The outbreak exploded in 2014, in dense 'ôhi'a groves in Hilo F...

How a USDA worker became an action-adventure comic character

Posted on 星期一, 10 十月 2016, 10:23

Just how does a humble federal worker in Washington end up as a rugged explorer in a widely syndicated comic strip? Well, from a simple call about a forest fire, the creative sparks flew. James Allen is the newest cartoonist behind “Mark Trail,” the King Features adventure-soap strip whose title character has been battling wilderness scofflaws for seven decades. And last year, as research for a new comic narrative, he needed some official information.

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。

为什么非洲需要充分的植物监测能力

Posted on 星期三, 24 八月 2016, 11:10

面对毁灭性的作物病虫害,非洲需要大力提升其植物监测能力。非洲农业上番茄斑潜蝇(Tuta absoluta )的紧急情况再次引起了关于非洲保护其当地农业生产和加强国际贸易方面的能力方面问题的讨论。并不难以得出这样的结论,更大规模层次上做好对于病虫害的准备工作是比将其交给那些以此为生计并且面对这他们并不知道的病虫害的农民更为有效的。这样,加强我们国家或者相关区域的植物保护能力将是关键。
