2016 SoE Marine Chapter - Case Study - Plankton and climate change

The Marine chapter of the 2016 State of the Environment (SoE) report incorporates multiple expert templates developed from streams of marine data. This metadata record describes the Case Study "Plankton and climate change". The full Case Study, including figures and tables (where provided), is attached to this record. Where available, the Data Stream(s) used to generate this Case Study are accessible through the "On-line Resources" section of this record.

DESCRIPTION OF THE FOCUS OF THE CASE STUDY
Plankton is the foundation of the marine food web and supports nearly all life in our oceans. Plankton species are sensitive indicators of ecosystem health and climate change because they are abundant, short-lived, not harvested, and sensitive to changes in temperature, acidity and nutrients.

ISSUES OF IMPORTANCE
On local scales plankton are sensitive to eutrophication, over regional scales to invasive species and fisheries, and over large continental scales to climate change. There is growing evidence from Australia that plankton communities are being altered by climate change and this is likely resonate up food webs to higher trophic levels.

DATA STREAM(S) USED IN CASE STUDY
IMOS plankton data – both from the National Reference Stations and the Australian Continuous Plankton Recorder survey.

### 案例研究聚焦内容
浮游生物是海洋食物网的基础，支撑着海洋中几乎所有生命活动。浮游生物类群作为生态系统健康与气候变化的敏感指示物，具有分布广泛、生命周期短促、未被捕捞且对温度、酸度及营养盐变化响应敏锐的特性。

### 重要关切议题
在局地尺度上，浮游生物对富营养化敏感；区域尺度上，其受入侵物种与渔业活动影响显著；而在大型陆架尺度上，气候变化则是主要胁迫因子。澳大利亚已有越来越多的研究证据表明，浮游生物群落正受到气候变化的干扰，并极有可能通过食物网传递至更高营养级，引发连锁生态效应。
