摘要
粪生菌孢是沉积物孢粉分析中“非花粉型”的重要组成部分,主要被用来指示大型食草动物种群数量变化以及重建早期牧业活动强度变化等。通过系统总结国内外粪生菌孢现代过程与古生态应用的研究实例发现:在现代过程研究方面,国外研究重点主要集中在粪生菌孢多样性、影响因子以及其传播、搬运和沉积过程,并发现Sporormiella-type、Sordaria spp.和Podospora sp.对食草动物活动指示性最好,尤其是Sporormiella-type被广泛应用于不同的研究区域;国内研究主要在青藏高原东北部,发现粪生菌孢与放牧活动强度之间具有较好的相关性。在古生态应用研究方面,国外研究发现Sporormiella-type很好地指示了大型食草动物的灭绝和放牧活动强度的变化;国内研究发现了早中全新世人类狩猎活动对食草动物的抑制以及以下主要变化时段:约5.6 ka牧业活动开始、约4.0 ka以后增强、在历史时期显著增强等。在未来研究中,应加强粪生菌孢现代过程调查,更深入地理解粪生菌孢的产生、传播、沉积和保存过程及其机制,探讨粪生菌孢与食草动物数量、植被状态、沉积环境和搬运动力之间的关系,结合多指标和跨学科的证据,更好地解译沉积地层粪生菌孢记录的古生态意义。粪生菌孢将在探究中晚全新世牧业起源和传播过程、驱动机理及生态影响等方面发挥不可替代的作用。
Coprophilous fungal spores, “Non-Pollen Palynomorph” parts of pollen analysis, are mainly used to reconstruct past changes in the population sizes of herbivores and intensity of pastoral activities. By systematically summarizing research examples of modern processes and paleoecological applications of coprophilous fungal spores at home and abroad, this study identified that foreign research has focused on the diversity, influencing factors, and dissemination, transportation, and deposition processes of coprophilous fungal spores. Sporormiella-type, Sordaria spp., and Podospora sp. have emerged as reliable indicators of herbivore activity;in particular Sporormiella-type coprophilous fungal spores have found widespread applications in different study areas. A strong correlation between coprophilous fungal spores and grazing activity has been found in the northeastern Qinghai-Tibetan Plateau. International paleoecological studies have demonstrated that Sporormiella-type fungal spores effectively indicate the extinction of large herbivores and fluctuations in grazing intensity. Domestic studies have identified the suppression of human hunting activities by herbivores during the Early and Middle Holocene. Key transitional periods were identified, such as the beginning of grazing activity about 5.6 ka, an increase after approximately 4.0 ka, and a significant increase during the historical period. In future research, it will be necessary to enhance the modern processes of coprophilous fungal spores investigation to understand the production, transmission, deposition, and preservation of coprophilous fungal spores and the mechanisms involved. Additionally, to explore the relationship between coprophilous fungal spores and herbivore population sizes, vegetation status, sedimentary environment, and transport dynamics to provide valuable information for the accurate interpretation of fossil coprophilous fungal spore records of natural sedimentary strata by combining multiple indicators and employing interdisciplinary e
