藻类能量途径:北部泥炭地能量转移的新机制
微生物光自养生物(即藻类)对全球碳循环的重要性日益得到认可。在泥炭地等碳积累生态系统中尤其如此,这些生态系统的碳储存能力很大,但也容易受到气候变化的影响。泥炭地未来储存碳的潜力在很大程度上取决于微生物介导的碳循环的规模。气温升高促进了通过传统碎屑能量途径(即泥炭形成)储存的二氧化碳(CO2)的释放,但气候变化也促进了整个北方景观中水生栖息地的扩张,并增加了营养物质的可用性,从而促进了通过藻类能量途径的碳吸收。藻类为微生物循环和更高营养水平提供了一种不稳定的能量来源,使这种新的能量途径容易受到自上而下的调节。合成。我们综合了来自北部泥炭地的研究,展示了气候变化导致的近期环境条件如何通过调节泥炭表层微生物的组成来控制二氧化碳的排放。我们强调了诸如扩大水生栖息地面积和加强营养循环等有利于藻类介导的碳吸收的条件,并证明了藻类能量途径的存在或缺失如何决定泥炭地碳通量的方向。

期刊介绍: Journal of Ecology publishes original research papers on all aspects of the ecology of plants (including algae), in both aquatic and terrestrial ecosystems. We do not publish papers concerned solely with cultivated plants and agricultural ecosystems. Studies of plant communities, populations or individual species are accepted, as well as studies of the interactions between plants and animals, fungi or bacteria, providing they focus on the ecology of the plants. We aim to bring important work using any ecological approach (including molecular techniques) to a wide international audience and therefore only publish papers with strong and ecological messages that advance our understanding of ecological principles.
