Special Issue Information

Dear Colleagues,

Forest ecosystems perform a wide range of services, sustaining biodiversity and providing fiber and fuel. In addition, forests may also mitigate climate change through carbon sequestration and local precipitation regulation. Forest biomass is crucial for these processes. Accurately measuring and estimating forest biomass, as well as elucidating its response to climate change and human activities, are thus essential for both ecology and forest management development. However, due to the complexity and variability in forest communities’ composition and structure, the measurement and estimation of forest biomass, especially belowground biomass, faces great challenges. Therefore, investigating aboveground and belowground interactions and biomass in varying forest types is vital to improving our understanding of forests’ ecosystem services and functions and to determining optimal management policies.

In this Special Issue of Forests, we aim to present the latest advances in the field of aboveground and belowground interactions and biomass surveys in diverse areas, including original studies, synthesis, and perspectives. This Special Issue will place particular emphasis on investigating biomass (and the carbon therein), its turnover in forests, and exploring the responses of forest biomass/productivity to environmental factors. With this aim in mind, we invite the submission of papers detailing advances in techniques and methodologies with respect to forest biomass determination.

Potential topics include, but are not limited to:

  • Aboveground and belowground interactions in forests;
  • Biomass/carbon allocation between above-ground and below-ground;
  • Forest productivity and climate change;
  • Biomass/carbon turnover in forests;
  • Litter production and decomposition;
  • Biomass dynamics under forest management;
  • Techniques and methodologies for aboveground and belowground biomass determination.

Mangrove ecosystems are pivotal to the global carbon budget. However, there is still a dearth of research addressing the impact of regional mangrove land use and land cover change (LUCC) on carbon sequestration and its associated spatial distribution patterns. To investigate the impact of different development scenarios on the carbon storage capacity of mangrove ecosystems, we focused on Hainan Island. We used LUCC data from 2010 to 2020 from mangrove-inhabited regions. The Markov-PLUS model was applied to predict the spatiotemporal dynamics of mangrove coverage under the natural increase scenario (NIS) and the mangrove protection scenario (MPS) over the next 40 years. Carbon storage was estimated using the InVEST model based on field-measured carbon density data. The outcomes show the following: (1) The Markov-PLUS model, with an overall accuracy of 0.88 and a Kappa coefficient of 0.82, is suitable for predicting mangrove distribution patterns on Hainan Island. (2) Environmental factors were the main drivers of historical mangrove changes on Hainan Island, explaining 54% of the variance, with elevation, temperature, and precipitation each contributing over 13%. (3) From 2025 to 2065, the mangrove area on Hainan Island is projected to increase by approximately 12,505.68 ha, mainly through conversions from forest land (12.73% under NIS and 12.37% under MPS) and agricultural land (39.72% under NIS and 34.53% under MPS). (4) The carbon storage increment within Hainan Island’s mangroves is projected at 2.71 TgC over the whole island, with notable increases expected in the eastern, northern, and northwestern regions, and modest gains in other areas. In this study, we comprehensively investigated the spatiotemporal dynamics and future trends of carbon storage in the mangroves of Hainan Island, offering invaluable guidance for the long-term management of mangrove ecosystems and the realization of carbon neutrality goals by 2060.

To address the ecological challenges arising from pure forest plantations and the wood supply–demand imbalance, implementing sustainable forest management is paramount. Accordingly, we studied crop trees at three densities (100, 150, and 200 N/ha) in a subtropical Pinus massoniana plantation. Our study revealed that the dominant phyla and genera within the fungal community remained largely consistent, with Basidiomycota and Ascomycota occupying prominent positions. Notably, the β diversity of the fungal community exhibited significant changes. Ectomycorrhizal and saprophytic fungi emerged as crucial functional guilds, and crop-tree thinning contributed to increased complexity within the fungal network, with a prevalence of positive rather than negative correlations among genera. The significant roles played by Camphor plants and ferns were evident in the fungal networks. Additionally, under crop-tree thinning, plant diversity experienced a significant boost, fostering interactions with the fungal community. Herb diversity played a vital role in the fungal community, affecting it either directly or indirectly, by altering the content of total phosphorus or organic matter in the soil. This study underscores the relationship between undergrowth plants and soil fungal communities, offering a scientific basis for evaluating the sustainability of restoring inefficient forest-plantation ecosystems.

Plant–soil feedback (PSF) was initially developed in the field of agricultural practices. In recent years, PSF has been extended to various ecosystems. Root exudates, essential for the exchange of materials, energy, and information at the plant–soil interface, significantly influence PSF. However, how PSF is driven by root secretions and the role of these secretions in different PSF pathways still needs to be further explored, particularly in forest ecosystems. Soil nutrients, microbial communities, and nematodes are important research topics in the process of PSF driven by root exudates. Investigating these aspects driven by root exudates provides valuable insights into the complex interactions both above ground and below the surface. This research can offer theoretical support and guidance for building stable, healthy, and sustainable forest ecosystems in the future. Full article
