概括

环境DNA (eDNA) 采样提供了入侵物种的早期检测. 一个结构化的决策框架显示,eDNA检测对鱼是可行的,但对植物却不是,这取决于入侵潜力和息地.

科学领域:

生态生态学生态生态学
环境科学环境科学
保护生物学保护生物学

背景情况:

环境DNA (eDNA) 采样是检测新引入物种的敏感工具.
将eDNA检测集成到早期检测快速响应 (EDRR) 程序中具有挑战性,因为积极的结果并不总是确认感染.

研究的目的:

通过结构化决策 (SDM) 框架,评估针对侵袭性水生植物的假设eDNA检测的响应行动.
将这些发现与对入侵贝进行的类似SDM研究进行比较,并为eDNA监测提供一个可概括的SDM框架.

主要方法:

应用了SDM框架来评估对缅因州塞巴戈湖侵入性水生植物eDNA检测的反应.
将结果与之前的SDM研究对犹他州乔丹内尔水库的入侵贝进行对比.
为eDNA EDRR场景开发了一个一般的SDM框架和启发式.

主要成果:

塞巴哥湖水生植物的eDNA检测无法采取行动,因为入侵潜力有限,现有有效缓解措施有效.
在Jordanelle水库中检测到的贝的eDNA是可以采取行动的,由于高入侵潜力,支持制工作.
SDM方法有效地突出了息地和物种属性如何影响eDNA检测的可操作性.

结论:

eDNA EDRR 程序的实用性取决于上下文,需要定制的决策框架.
SDM提供了一种可靠的方法来评估对不确定的eDNA检测的反应,特别是在时间限制下.
一个通用的SDM框架可以指导基于eDNA监测的各种入侵物种的快速反应策略.

Threats to Biodiversity

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

DNA Isolation

DNA Isolation

DNA isolation protocols can be fast and straightforward or complex and time-consuming depending on the type and quality of DNA required for further processing. For example, plasmid DNA extraction is a bit more complicated than genomic DNA extraction because of the need for an appropriate lysis method to separate plasmid DNA from gDNA during isolation. However, for specific applications, such as long-range DNA sequencing that require a good yield of high- quality DNA samples, we need to follow...
