AI Article Synopsis

  • Stream water samples were collected monthly from March to October 2006 in Liangshui Nature Reserve to study hydrochemical characteristics across different forest types.
  • Major cations found were ranked as Ca2+ > Na+ > K+ > Mg2+, while anions followed the order HCO3(-) > SO4(2-) > NO3(-) > Cl(-).
  • The spruce-fir forest had higher average contents of Na+, Ca2+, Mg2+, Fe2+, and Fe3+, while K+ was highest in the larch plantation, which also showed the highest average monthly anion content.

Article Abstract

Stream water samples under the Korean pine broad-leaved forest, spruce-fir forest, and larch plantation in Liangshui Nature Reserve of Xiaoxing' an Mountains were collected monthly from March to October 2006 to study the dynamic changes of their hydrochemical characteristics. The results indicated that the content of major cations in the streams was in the sequence of Ca2+ > Na+ > K+ > Mg2+, and that of anions was HCO3(-) > SO4(2-) > NO3(-) > Cl(-). The average content of Na+, Ca2+, Mg2+, Fe2+ and Fe3+ was in the order of spruce-fir forest > larch plantation > Korean pine broad-leaved forest, while that of K+ was in the order of larch plantation > spruce-fir forest > Korean pine broad-leaved forest. The average monthly content of anions in stream water was the highest under larch plantation.

We elucidated the changes of soil microbial biomass and community structure in soil profiles under four typical land use types (farmland, grassland, secondary forest and plantation)and across five soil layers (0-10, 10-20, 20-30, 30-40, 40-50 cm) in the northern mountainous region of Hebei Province. We measured soil microbial biomass by phospholipid fatty acid (PLFA) method, and investigated the effects of land use and soil depth on soil microbial biomass and community structure by variance analysis, correlation analysis and redundancy analysis. The results showed that soil water content, bulk density, and organic carbon content of farmland differed significantly from other land use types.

Article Synopsis
  • Soil microorganisms, particularly fungi, are crucial in nutrient cycling within ecosystems, but their distribution across soil depth is not well understood.
  • In this study, soil samples from various depths in Larix principis-rupprechtii plantations were analyzed using high-throughput sequencing to assess fungal composition and diversity.
  • Findings revealed that fungal diversity decreases with soil depth, with environmental factors like nitrogen and phosphorus significantly influencing community structure and interactions being more complex in deeper soil layers.

Attenuated asymmetry of above- versus belowground stoichiometry to a decadal nitrogen addition during stand development.

Ecology

December 2024

State Key Laboratory of Herbage Improvement and Grassland Agro-Ecosystems, College of Pastoral Agriculture Science and Technology, Lanzhou University, Lanzhou, China.

Deciphering the linkage between ecological stoichiometry and ecosystem functioning under anthropogenic nitrogen (N) deposition is critical for understanding the impact of afforestation on terrestrial carbon (C) sequestration. However, the specific changes in above- versus belowground stoichiometric asymmetry with stand age in response to long-term N addition remain poorly understood. In this study, we investigated changes in stoichiometry following a decadal addition of three levels of N (control, no N addition; low N addition, 20 kg N ha year; high N addition, 50 kg N ha year) in young, intermediate, and mature stands in three temperate larch plantations (Larix principis-rupprechtii) in North China.

As an important branch characteristic factor, the quantity of branches could influence crown structure, tree growth, and wood quality. Taking plantation in Dagujia Forest Farm, Qingyuan County, Liao-ning Province as the research object, we developed a mixed effect prediction model of the first-order branches quantity of including sprouting branches based on the negative binomial distribution model, and a mixed effect prediction model of the first-order branches density of including sprouting branches based on the negative exponential model. The results showed that the mixed effect model considering sample level as the random effect effectively decreased the heteroscedasticity and autocorrelation.

This study was conducted in Liupanshan Forest Ecological Positioning Station of the National Forestry and Grassland Administration. We monitored sap flow of plantation in the Xiangshui River sub-basin throughout the 2019 growing season (from May 17 to October 12), as well as the meteorological conditions and soil environment (soil temperature and soil water content), to analyze the comprehensive environmental responses of sap flow in under different weather conditions. The results showed that sap flow rate increased and then decreased on the daily scale, with the highest rate on sunny days, followed by overcast days and then rainy days.
