Introduction
My main research topic is the ecology of VOCs emissions in the soil, and their biological and environmental effects. I am particularly interested in the responses of VOCs from forest soils to global change (drought and enhanced N) and I also study changes in root exudate profiles, due to environmental change, in the field. This work highlights how forests will respond to a changing world through the variation of VOCs and root exudates.

Biogenic volatile organic compounds (BVOCs) play critical roles in ecosystems at various scales, influencing above-and below-ground interactions and contributing to the atmospheric environment. Nonetheless, there is a lack of research on soil BVOC fluxes and their response to environmental changes. This study aimed to investigate the impact of drou...
Despite the vital role in carbon (C) sequestration and nutrient retention, variations and patterns in root C and nitrogen (N) stoichiometry of the first five root orders across woody plant species remains unclear. We compiled a dataset to explore variations and patterns of root C and N stoichiometry in the first five orders of 218 woody plant speci...
Litter humification is an essential process of soil carbon sequestration in forest ecosystems, but the relationship between soil fauna and humic substances has not been well understood. Therefore, a field litterbag experiment with manipulation of soil fauna was carried out in different soil frozen seasons over one year in cold forests. The foliar l...
Terrestrial vegetation is the largest contributor of isoprenoids (a group of biogenic volatile organic compounds (BVOCs)) to the atmosphere. BVOC emission data comes mostly from temperate regions, and less is known about BVOC emissions from tropical vegetation, even though it is estimated to be responsible for >70% of BVOC emissions. This review su...
Nitrogen (N) deposition poses a threat to terrestrial biodiversity and ecosystem functioning globally. However, little is known concerning how the structure and function of litter fauna communities will respond in this context. Here, a gradient of N deposition (0, 20, and 40 kg N ha−1 yr−1) was simulated in a subtropical forest of southwestern Chin...
Winter climate change has great potential to affect the functioning of terrestrial ecosystems. In particular, increased soil frost associated with reduced insulating snow cover may impact the soil nitrogen (N) dynamics in cold ecosystems, but little is known about the variability of these effects among the soil aggregates. A snow manipulation exper...

Background
Snow cover change has a great potential to impact soil nitrogen (N) pools and enzyme activities in boreal forests. Yet, the nature of this biochemical processes within soil aggregates is still limited. We conducted a snow manipulation experiment to investigate the effects of snow absence on N pools and enzyme activities within soil aggre...

Litter decomposition plays a critical role in regulating biogeochemical cycles in terrestrial ecosystems and is profoundly impacted by increasing atmospheric nitrogen (N) deposition. Here, a N manipulation experiment was conducted to explore the effects of N additions (0 kg N ha−1 yr−1, 20 kg N ha−1 yr−1 and 40 kg N ha−1 yr−1) on decay rates and nu...
Increased soil frost associated with winter climate change could have immediate and carry-over effects on biological processes in high-altitude forest soils, but the nature of these processes remain poorly understood. We conducted a snow-exclusion experiment to investigate the immediate and cross-seasonal effects of increased soil frost on soil CO2...
Partitioning the components of soil respiration is crucial to understand and model carbon cycling in forest ecosystems. In this study, total soil respiration (RS), autotrophic respiration (RA), heterotrophic respiration (RH), litter respiration (RL), litterfall input and environmental factors were synchronously monitored for 2 years in a subtropica...

Moss is an essential component in most forest ecosystems, and plays critical roles in material cycling and water retention. It is also an indicator of environmental change. An increasing numbers of studies have demonstrated that the growth and reproduction of mosses can be determined by light regime, substrate, and hydro-thermal dynamics. Theoretic...
Atmospheric nitrogen (N) deposition has become a global environment problem, which has a significant effect on the structure and function of terrestrial ecosystem. From August 2015 to July 2016, we investigated and analyzed the concentration of different forms of nitrogen in the precipitation in the forest ecosystem of Lingyan Mountain, Dujiangyan....
The soil samples from two layers-0-20 and 20-40 cm depth-were collected from the plantations of Cryptomeria fortunei, Michelia wilsonii, Phoebe zhennan, and Quercus acutissima in the Lingyan Mountain, Dujiangyan along the western edge of the Sichuan Basin. Six aggregate sizes were obtained by the dry sieve method. Soil organic carbon, nitrogen, and...
The objective of this study was to investigate the soil nitrogen components of four native artificial plantations at the western edge of the Sichuan Basin. Soil samples from two layers (0-20 cm and 20-40 cm) were collected from 4 plantations (Cryptomeria fortunei, Michelia wilsonii, Phoebe zhennan, and Quercus acutissima) during March, June, Septem...
