Special Issue Information

Dear Colleagues,

Forest ecosystems play a critical role in mitigating climate change by sequestering atmospheric CO2 through photosynthesis and storing carbon in biomass and soil, and nitrogen cycling, a key driver of forest productivity, significantly influences carbon sequestration and ecosystem resilience. However, climate change—characterized by rising temperatures, shifting precipitation patterns, and more frequent extreme weather events—poses significant challenges to forest carbon and nitrogen budgets. Simultaneously, forest management practices, such as harvesting, thinning, afforestation, and fire management, profoundly influence these budgets by altering biomass accumulation, soil processes, and nutrient availability. Despite their importance, the combined effects of climate change and forest management on carbon and nitrogen budgets remain insufficiently explored across spatial and temporal scales. 

This Special Issue seeks to advance our understanding of the synergistic impacts of climate change and forest management on forest carbon and nitrogen budgets. By fostering interdisciplinary research, we aim to inform sustainable forest management strategies in a rapidly changing world. Consequently, the scope of this Special Issue includes both natural and managed forest ecosystems across temperate, boreal, and tropical biomes. 

We invite submissions of original research articles, reviews, and meta-analyses that examine the effects of climate change and forest management on forest carbon and nitrogen dynamics. Contributions should be scientifically robust, innovative, and relevant to the journal’s readership.

Abstract
Understory vegetation (shrubs and herbs) mediates belowground biogeochemical processes in forests through litter inputs, root exudation, and microenvironmental regulation; however, the magnitude of these regulatory effects remains poorly quantified.

Understory vegetation (shrubs and herbs) mediates belowground biogeochemical processes in forests through litter inputs, root exudation, and microenvironmental regulation; however, the magnitude of these regulatory effects remains poorly quantified. Here, we conducted a 10-year small-scale understory vegetation manipulation experiment in a coniferous–broadleaf mixed forest in central China, aiming to systematically assess the impacts of understory vegetation on soil carbon (C), nitrogen (N), and phosphorus (P) dynamics. Two experimental treatments were established: (1) the “None” treatment (removal of both understory vegetation and litter) and (2) the “Understory” treatment (litter removal while retaining understory vegetation). Results indicated that compared with the “None” treatment, the “Understory” treatment did not significantly alter the concentrations or stocks of soil organic C (SOC) and total N (p > 0.05), suggesting a weak responsiveness of SOC and total N to understory vegetation presence. In contrast, understory vegetation exerted a significant positive effect on soil P fractions: total P concentration and stock increased by 3.97% and 2.68%, organic P by 6.65% and 5.32%, and available P by 46.38% and 43.96%, respectively (p < 0.05). These results demonstrate that understory vegetation exerts a more pronounced regulatory effect on soil P dynamics than on C and N dynamics. In conclusion, understory vegetation plays a pivotal role in promoting soil P sequestration and improving P availability in coniferous–broadleaf mixed forest ecosystems. We recommend retaining understory vegetation in forest management practices to sustain soil P availability and mitigate widespread P limitation in such ecosystems. Full article

Soil water availability and nitrogen (N) deposition critically influence biogenic volatile organic compound (BVOC) emissions, thereby affecting atmospheric chemistry. However, their differential short- and long-term effects remain unclear. Here, Ormosia pinnata and Pinus massoniana seedlings were exposed to three water regimes (moderate drought, MD; normal irrigation, NI; near-saturated irrigation, NSI) and two nitrogen (N0; 0 kg N ha−1 yr−1; N80; 80 kg N ha−1 yr−1) treatments for 20 months. Branch-level BVOC emissions and leaf physiological and biochemical traits were examined after 8 months (short term) and 16 months (long term). In the short term, P. massoniana predominantly emitted α-pinene, β-pinene, and γ-terpinene, whereas O. pinnata emitted isoprene (ISO). After prolonged exposure, ISO became the dominant in both species. Short-term MD and NSI conditions stimulated ISO emissions in O. pinnata, with N80 addition further amplifying this effect. In contrast, long-term treatments tended to suppress ISO emissions in O. pinnata, particularly under N80. Short-term water treatments had no significant effect on monoterpene (MT) emissions in P. massoniana. Under long-term water treatments, N80 suppressed ISO emissions; nevertheless, ISO emission rates (ISOrate) progressively increased with increasing soil water availability. Although leaf intercellular CO2 concentration (Ci), stomatal conductance (gs), and photosynthesis-related enzymes exhibited partial correlations with BVOC emissions, an overall decoupling between leaf traits and emission patterns was evident. Our findings demonstrate the significant changes in both BVOC composition and emission magnitudes under the joint effects of water availability and nitrogen deposition, providing important implications for improving regional air quality modeling and BVOC emission predictions.
