“…Coarse woody debris decomposition within forest gaps is influenced by a variety of environmental factors such as solar radiation, moisture, and temperature [104]; downed woody debris (DWD) produces microbial communities that contribute to biodiversity enhancement [105]; light and soil moisture content can increase soil microbial diversity [106,107]. Environmental factors such as microclimate, microtopography, and soil temperature and moisture are drivers of microbial community change and have a large impact on altering surface apoplastic decomposition and soil nutrient cycling [108,109].…”

Forest gaps, which are formed by small-scale disturbances that often occur in forest communities, are the most dominant form of disturbance in many types of forests around the world and play an essential role in the dynamics of forest regeneration, plant diversity conservation, nutrient cycling, and forest succession. Forest gaps are one of the vital directions in forest research. Dynamic disturbance and vegetation regeneration are important elements of forest gap research. The research on forest gaps has a history spanning over 70 years, but there is a lack of a systematic overview of the process. Therefore, this review outlines the spatial changes in the whole process of forest gap development by systematically analyzing the occurrence, basic characteristics, micro-environmental changes, and the effects of forest gap disturbance processes on understory animals, plants, soil microorganisms, and forest regeneration and succession. The results contribute to a better understanding of forest gaps and their impacts on forest regeneration and management. Based on this, we remapped the forest gap process during forest succession. We suggest directions and recommendations for improvements in response to the dilemmas and challenges facing the future of forest gaps.

“…Given that it provides a habitat and food supply for a variety of creatures [4] and is an active participant in the carbon (C) and nutrient cycles of forests [5,6], DWD has a major effect on the structure and function of forests. The production of DWD alters forest canopy openings [7], the formation of soil microclimates [8], and soil physicochemical properties [9], all of which affect the growth and activity of the soil microbial community [10]. Numerous studies suggest that soil quality and health improve with the decomposition of DWD [9,11].…”

Downed woody debris (DWD) can alter the chemical and biological properties of forest soils, and this process is affected by the degree of DWD decay. Our aim was to assess the effects of the entire decay process of DWD on the associated soil microbial communities. Here, we examined the differences in soil microbial community size and composition among five decay stages (DC Ⅰ–Ⅴ) of Masson pine (Pinus massoniana Lamb.) at two soil depths in a climate transitional forest and then linked these differences to soil chemical properties. The decay of DWD increased soil total PLFAs, and the complexity of soil microbial networks was highest in stage Ⅱ and then decreased with the decay stage. The relative abundance of fungi increased with the decay stage, while the relative abundance of gram-positive bacteria decreased with the decay stage. The microbial community composition at a soil depth of 0–10 cm was mainly driven by soil pH and organic C (SOC), and at a depth of 10–20 cm, soil pH was the primary determinant of microbial community composition. Our findings suggest that DWD decomposition reduces microbial physiological stress, promotes fungal growth, and stimulates microbial biomass, highlighting the positive impact of DWD on forest soils. Future research is needed to elucidate the universal effects of DWD decomposition on soil properties, especially focusing on the response of soil microbial processes to the decomposition time of DWD.
