Changes in leaf litter decomposition of primary Korean pine forests after degradation succession into secondary broad-leaved forests
<p>Forest degradation succession often leads to changes in forest ecosystem functioning. Exactly how the decomposition of leaf litter is affected in a disturbed forest remains unknown. Therefore, in our study, we selected a primary Korean pine forest (PK) and a secondary broad-leaved forest (SF) affected by clear-cutting degradation, both in Northeast China. The aim was to explore the response to changes in the leaf litter decomposition converting PK to SF. The mixed litters of PK and SF were decomposed in situ (one year). The proportion of remaining litter mass, main chemistry, and soil biotic and abiotic factors were assessed during decomposition and then we made an in-depth analysis of the changes in the leaf litter decomposition. According to our results, leaf litter decomposition rate was significantly higher in the PK than that in the SF. Overall, the remaining percent mass of leaf litter's main chemical quality in SF was higher than in PK, indicating that leaf litter chemical turnover in PK was relatively faster. PK had a significantly higher amount of total phospholipid fatty acids (PLFAs) than SF during decomposition. Based on multivariate regression trees, the forest type influenced the soil habitat factors related to leaf litter decomposition more than decomposition time. Structural equation modeling revealed that litter N was strongly and positively affecting litter decomposition, and the changes in actinomycetes PLFA biomass played a more important role among all the functional groups. Selected soil abiotic factors were indirectly driving litter decomposition through coupling with actinomycetes. This study provides evidence for the complex interactions between leaf litter substrate and soil physical-chemical properties in affecting litter decomposition via soil microorganisms.</p>

Influence of soil type and vertical zonation on soil fungal communities associated with natural jack pine forests
<p>Natural jack pine forests established on sandy eskers and clayey soils represent a unique habitat in the boreal forest in northeastern Canada and are generally associated with well-differentiated soil horizons, but little is known regarding their soil fungal diversity and how soil type and vertical zonation would shape their communities. To address this question, we characterized soil fungal communities from litter, organic and mineral horizons in 18 natural jack pine forests in esker and clayey soils using ITS2 rDNA metabarcoding. Ectomycorrhizal fungi dominated the organic and mineral horizons in esker soils, while saprotrophic fungi were dominant in clayey soils. The dominance of ectomycorrhizal fungi coincided with higher C accumulation within the organic horizon in esker soils. The nutrient-poor and more acidic esker sites harbored less diverse ectomycorrhizal and saprotrophic communities than clayey soils. Several stress-tolerant and melanin-rich fungal taxa were indicators of esker soils. However, fungal communities were more distinct between horizons than soil types and soil type effects differed along the soil profile. Our findings highlight the need to fill knowledge gaps in soil fungal diversity associated with jack pine forests and pave the way for adapted and multi-resource forest management in esker forest ecosystems considering their underground fungal specificities.</p>
