不同生长基质对白云山国家森林公园苔藓谱系多样性的影响

Effects of different growth substrates on phylogenetic diversity of bryophytes in Baiyunshan National Forest Park

  • 摘要: 本研究分析了洛阳白云山国家森林公园1 hm2样地内腐木、岩石、树干和土壤等4种不同生长基质上苔藓植物的谱系多样性,探讨了地形与光照对不同基质苔藓植物谱系多样性的影响,以及不同生境苔藓植物谱系多样性变化的原因。结果显示:样地内土壤生苔藓植物的谱系多样性最高,而树附生苔藓植物的谱系多样性最低;腐木生苔藓植物谱系多样性与坡度、冠层覆盖度和平均叶倾角显著相关;土壤生苔藓植物谱系多样性与总透光比、冠层下散射辐射以及冠层下的总直接辐射相关性显著;岩石生苔藓植物谱系多样性仅与凹凸度显著相关;而树附生苔藓植物的谱系多样性与地形和光照均无显著相关性。同时,光照与地形通过复杂的互作共同影响苔藓植物的谱系多样性。

     

    Abstract: Phylogenetic diversity contains pedigree relationships and evolutionary information among species and can reveal evolutionary differences among species, which is of great significance for studies on bryophyte community diversity at the micro level. In this study, we explored phylogenetic diversity of bryophytes on four different growth substrates (rotten wood, rocks, tree trunks, and soil) in a 1 hm2 plot of Baiyun Mountain National Forest Park in Luoyang,Henan, China. We analyzed the effects of topography and light on bryophyte pedigree diversity in different substrates and explored the causes of bryophyte phylogenetic diversity variation in different habitats. Results showed that the phylogenetic diversity of soil bryophytes was the highest, while that of tree epiphytes was the lowest. The phylogenetic diversity of rotten wood bryophytes was significantly correlated with slope, canopy coverage, and average leaf inclination. The phylogenetic diversity of soil bryophytes was significantly correlated with total light transmittance, scattered radiation under the canopy, and total direct radiation under the canopy. The phylogenetic diversity of rock bryophytes was only correlated with unevenness. The phylogenetic diversity of epiphytic bryophytes showed no significant correlation with topography or light. At the same time, light and topography showed significant correlations, with both playing a role in bryophyte pedigree diversity through complex interactions. Studying the effects of different growth substrates on phylogenetic diversity can deepen our understanding of the relationship between bryophyte diversity and habitat from the perspective of phylogenetic relationships and provide a reference for future conservation of bryophyte diversity.
