Fungal Diversity in Fire-Affected Pine Forest Soils at the Upper Tree Line

Forests, Journal Year: 2024, Volume and Issue: 15(11), P. 2012 - 2012

Published: Nov. 15, 2024

Forest fires represent a significant ecological disturbance in ecosystems that increasingly affects Pinus heldreichii H. Christ forests at the upper tree line Montenegro, due to climate change and anthropogenic factors. Soil samples were collected from five high-altitude sites Kuči Mountains, including three post-fire (2-, 4-, 6-years post-fire) two unburned control sites. High-throughput sequencing soil chemical analyses conducted assess fungal diversity, community composition, nutrient properties. The results showed diversity was significantly higher soils compared soils, with most prominent changes ectomycorrhizal fungi, which are crucial for pine regeneration. composition differed markedly between sites, specific taxa such as Hygrocybe conica (Schaeff.)

Despite this, richness did not over time or post-fire), suggesting slow recovery of communities In addition shifts biodiversity, exhibited levels available phosphorus, likely conversion organic phosphorus into soluble forms during combustion. However, matter content remained unchanged. This study provided important insights long-term impacts forest on underlined importance preserving areas maintain biodiversity support natural regeneration, well potential need active restoration strategies fire-affected regions.

Tree species identity affects soil P bioavailability by altering labile organic P after tree mixing in subtropical China

European Journal of Soil Science, Journal Year: 2024, Volume and Issue: 75(5)

Abstract Converting monocultures to mixed plantations has been emphasized improve ecosystem productivity and services. However, the impact of tree species identity on phosphorus (P) bioavailability in acidic soils subtropical China, where P is relatively scarce, not fully understood. This study explored changes soil biologically‐based fractions effect mineral microbial properties transformation after mixing five broadleaved trees ( Bretschneidera sinensis, Manglietia conifera, Cercidiphyllum japonicum, Michelia maudiae Camellia oleifera ) individually with coniferous Pinus massoniana ). The results showed that most significantly increased pH citric acid decreased exchangeable Fe 3+ Al activation oxides compared monospecific plantations, which reduced precipitation adsorption. Mixed planting phosphatase activity altered community composition P‐mobilizing bacteria carrying phoD pqqC genes, contributed organic mineralization inorganic (Pi) desorption. biomass relative rate turnover. Labile (Enzyme‐P) was a potentially significant source soluble Pi (CaCl 2 ‐P) among fractions, plus P. Overall, introducing species, especially (e.g. japonicum , high litter quality belowground secretions acid, phosphatase), solubilization recalcitrant (HCl‐P), desorption chemisorbed (Citrate‐P) accumulation Enzyme‐P, thereby increasing available pools. Redundancy analysis demonstrated were mainly driven by phosphatases, cations, floor fresh lignin/N acid. Altogether, we highlight importance choosing mixtures have synergistic or complementary effects when constructing order alleviate limitations.
