Effects of sedimentation and the herbicide diuron on crustose coralline algae (CCA)

Experiments were conducted to determine the effects of sedimentation and the herbicide diuron on crustose coralline algae (CCA). Three species of CCA were subjected to exposure to sediments and one species to sediments and diuron individually and in combination. This research aimed to observe altered photophysiology, bleaching and survival.

Three species of CCA were collected from midshelf reefs along the Innisfail coastline, H. reinboldii, Neogoniolithon fosliei and Porolithon onkodes. P. Onokodes was also collected from Davies reef for the combined sediment and diuron experiments.

Variations in sediment type included estuarine sediment collected from the Herbert River and offshore sediment Otter Reef:

本研究通过实验探究沉积作用与除草剂敌草隆（diuron）对结壳状珊瑚藻（crustose coralline algae，以下简称CCA）的影响。实验设置为选取3种CCA开展沉积物暴露实验，另选取1种CCA分别进行单独沉积物暴露、单独敌草隆暴露，以及二者联合暴露处理。本研究旨在观测受试藻种的光生理特性变化、白化现象与存活状况。

本次实验所用的3种结壳状珊瑚藻均采自因尼斯费尔（Innisfail）沿岸的陆架中部礁体，包括H. reinboldii、Neogoniolithon fosliei与Porolithon onkodes。

Porolithon onkodes（缩写P. onkodes）亦可采自戴维斯礁（Davies Reef），用于沉积物与敌草隆的联合暴露实验。

实验所用沉积物类型涵盖两类：采自赫伯特河（Herbert River）的河口沉积物，以及采自奥特礁（Otter Reef）的离岸沉积物：
