2016/11/4
The oceans hold a vast reservoir—700 billion tons—of carbon, dissolved in seawater as organic matter, often surviving for thousands of years after being produced by ocean life. Yet, little is known ab...
As they grow, corals are bathed in a sea of marine microbes, such as bacteria, algae, and viruses. While these extremely abundant and tiny microorganisms influence coral communities in a variety of wa...

研究称大型海洋动物灭绝风险更高
大型海洋动物 灭绝 风险
2016/9/18
美国最新研究发现，在现代海洋中，大型海洋动物面临灭绝的风险比小型海洋动物更大。这很可能是人类捕鱼活动造成的。美国斯坦福大学等机构的研究人员聚焦软体动物和脊椎动物这两大类海洋动物，分析过去500年它们面临的灭绝风险程度与体重等生态特征之间的关联。结果显示，现代海洋中海洋动物的灭绝风险与较大体型之间存在强烈关联，大型海洋动物有选择性地成为灭绝目标。

水下显微镜可高分辨率拍摄海洋生物
海洋生物 水下显微镜
2016/7/18
美国加州大学圣迭戈分校的研究小组日前开发出一种新型水下显微镜，能够以高清晰度拍摄在自然环境中生活的海洋生物。该显微镜的分辨率可达微米级别，远超此前同类设备20到50微米的水平，有助于人们更好地了解海洋生态环境。
全球珊瑚礁鱼类生物量分布确认加强渔业管理有助珊瑚礁保护
全球珊瑚礁鱼类生物量分布 渔业管理 珊瑚礁保护
2016/7/5
英国《自然》杂志2016年6月16日发表的一篇生态学论文，确认了世界范围内鱼类生物量显著高于或者低于预期值的珊瑚礁。这些发现得益于一种综合考虑环境和社会经济学因素的新的跨学科方法，其研究结果可能有助于解决全球珊瑚礁退化问题。珊瑚礁可为许多动植物提供生活区域，同时很大程度地影响着周围环境的物理和生态条件。此次，澳大利亚詹姆斯库克大学约书亚·辛那和他的研究团队，利用从全球2512个珊瑚礁中收集的数据开...
