摘要

泥炭地储存了大量的碳(C),这一功能可能受到气候变化的威胁。由维管束垫植物组成的泥炭地广泛分布于安第斯山脉北部和中部高地(páramo、湿润和干燥的 puna),但人们对它们的碳动态却知之甚少。为了了解泥炭地碳动态的主要驱动因素之间的相互作用,并推断整个安第斯地区的地理模式,我们探讨了以下问题:地形、水文、温度、过去的气候变异和植被如何影响这些泥炭地的碳动态?我们总结了有关热带和亚热带安第斯山脉垫泥炭地发展的空间观测模式和时间推断模式的现有信息。在此基础上,我们认识到以下新出现的模式,这些模式都需要在针对碳积累的空间和时间模式的进一步研究中进行检验:(1)气候干燥的泥炭地和集水面积较大的泥炭地比潮湿的普纳和帕拉莫泥炭地以及集水面积较小的泥炭地接受更多的沉积物输入。这导致泥炭地层中夹杂着矿物层,并通过引发植被变化影响碳积累。(2) 水位高且恒定有利于碳积累。与帕拉莫相比,干湿普纳地区的季节性水位波动较大,导致普纳地区的碳损失更为频繁。(3) 较高的温度有利于在高水位和恒定水位条件下的碳增加,但也会增加在低水位和波动水位条件下的碳损失。(4) 碳积累在全新世一直变化不定,但一些泥炭地的碳积累率近期有所上升。(5) 植被通过物种生产力和分解率的差异影响碳动态。由于全球气候变化的表现形式(季节性、永久冻土行为、温度、降水机制)预计会存在区域差异,因此,目前,páramo地区的垫状泥炭地预计大多会继续作为碳汇,而干旱的puna地区的泥炭地则更有可能因日益干旱化而变成碳源。

Carbon dynamics in high-Andean tropical cushion peatlands: A review of geographic patterns and potential drivers

Peatlands store large amounts of carbon (C), a function potentially threatened by climate change. Peatlands composed of vascular cushion plants are widespread in the northern and central high Andes (páramo, wet and dry puna), but their C dynamics are hardly known. To understand the interplay of the main drivers of peatland C dynamics and to infer geographic patterns across the Andean regions, we addressed the following question: How do topography, hydrology, temperature, past climate variability, and vegetation influence the C dynamics of these peatlands? We summarize the available information on observed spatial and inferred temporal patterns of cushion peatland development in the tropical and subtropical Andes. Based on this, we recognize the following emerging patterns, which all need testing in further studies addressing spatial and temporal patterns of C accumulation: (1) Peatlands in dry climates and those in larger catchments receive higher sediment inputs than peatlands from wet puna and páramo and in small catchments. This results in peat stratigraphies intercalated with mineral layers and affects C accumulation by triggering vegetation changes. (2) High and constant water tables favor C accumulation. Seasonal water level fluctuations are higher in wet and dry puna, in comparison with páramo, leading to more frequent episodes of C loss in puna. (3) Higher temperatures favor C gain under high and constant water availability but also increase C loss under low and fluctuating water levels. (4) C accumulation has been variable through the Holocene, but several peatlands show a recent increase in C accumulation rates. (5) Vegetation affects C dynamics through species-specific differences in productivity and decomposition rate. Because of predicted regional differences in global climate change manifestations (seasonality, permafrost behavior, temperature, precipitation regimes), cushion peatlands from the páramo are expected to mostly continue as C sinks for now, whereas those of the dry puna are more likely to turn to C sources as a consequence of increasing aridification.

期刊介绍: The vision for Ecological Monographs is that it should be the place for publishing integrative, synthetic papers that elaborate new directions for the field of ecology. Original Research Papers published in Ecological Monographs will continue to document complex observational, experimental, or theoretical studies that by their very integrated nature defy dissolution into shorter publications focused on a single topic or message. Reviews will be comprehensive and synthetic papers that establish new benchmarks in the field, define directions for future research, contribute to fundamental understanding of ecological principles, and derive principles for ecological management in its broadest sense (including, but not limited to: conservation, mitigation, restoration, and pro-active protection of the environment). Reviews should reflect the full development of a topic and encompass relevant natural history, observational and experimental data, analyses, models, and theory. Reviews published in Ecological Monographs should further blur the boundaries between “basic” and “applied” ecology. Concepts and Synthesis papers will conceptually advance the field of ecology. These papers are expected to go well beyond works being reviewed and include discussion of new directions, new syntheses, and resolutions of old questions. In this world of rapid scientific advancement and never-ending environmental change, there needs to be room for the thoughtful integration of scientific ideas, data, and concepts that feeds the mind and guides the development of the maturing science of ecology. Ecological Monographs provides that room, with an expansive view to a sustainable future.
