Special Issue Information

Dear Colleagues,

Due to both anthropogenic and non-anthropogenic disturbance, tropical forests are being disturbed and converted to non-forest land uses. Functional diversity and ecosystem processes have undergone considerable alterations as a result, with repercussions for local, regional, and global biogeochemical cycles. Researchers have been working to understand how anthropogenic and non-anthropogenic interventions affect biodiversity, ecosystem structure, or biogeochemistry since the advent of land-use change, but it has only been more recently that they have started to investigate the additive or synergistic effects of land-use change and biodiversity loss on tropical ecosystem function. Deforestation and fragmentation, over-exploitation, invasive species and climate change are the main drivers of tropical forest biodiversity loss. Tropical deforestation has had great impacts on the global carbon cycle. Scientists came to the conclusion that anthropogenic land use and land cover changes (LULCCs) have substantial impacts on the loss of tropical forests, leading to a decrease of the forest carbon sink.

This Special Issue aims to collect relevant scientific contributions on the impacts of land use change and functional biodiversity loss on tropical ecosystem functions. In order to advance our general and theoretical understanding of how tropical land use change and functional biodiversity loss affect ecological processes and biogeochemical cycling, we want to find common trends and cross-cutting themes among various ecosystems and geographical locations. This could include research using remote sensing or field measurements using experimental, observational, or modeling techniques. Studies on direct and indirect influences of recent or past human disturbances on tropical ecosystems are invited. This includes direct human interventions such as selective logging, land clearing for farming and forestry, as well as indirect interventions like climate change, modifications on the troposphere’s chemistry (including atmospheric depositions), the introduction of invasive species, or changes to disturbance patterns. Studies that integrate biodiversity and ecosystem processes in order to understand how changes to biotic communities affect ecosystem functions are of particular interest.

Precise estimates of dendrometric and morphometric variables are indispensable for effective forest resource conservation and sustainable utilization. This study focuses on modeling the relationships between shape (morphometric), dimension (dendrometric) and density (N) to assess the sustainability of forest resources. It sheds light on the current state of site characteristics, reproduction, and the structure of Araucaria angustifolia trees at selected forest remnants across multiple sites in Santa Catarina, Southern Brazil. Individual trees and their dendrometric variables, such as the diameter at breast height (d), height (h), crown base height (cbh), annual periodic increment (API) in growth rings, and morphometric variables, including four radii of the crown in cardinal directions, were evaluated. These measurements allowed us to calculate various morphometric indices and crown efficiency, enabling the assessment of both vertical and horizontal structural conditions. Statistical analysis confirmed a positive relationship of the crown volume (cv) and crown surface area (csa) with the crown length (cl). Conversely, the crown efficiency, density, increment rate, and reproductive structure production declined. These morphometric relationships emphasize the complex dynamics within these forest ecosystems, irrespective of the chosen site, indicating that horizontal and vertical forest structures have stagnated and have been characterized by limited change in the last ten years. Such results raise concerns about sustainability, highlighting the need for proper conservation measures and sustainable forest management practices. Our findings underscore the need for substantial adjustments in the structure and dynamics of the forest, particularly on selected rural properties where this tree species is abundant, to ensure long-term sustainability.

Mangrove forests play an important role in coastal areas from an ecological perspective, being able to store large amounts of carbon through sequestration and inhibiting climate change processes by absorbing CO2 in the atmosphere. In recent years, there have been changes in the land cover of converted and degraded mangrove forests which have resulted in the release of carbon and an imbalance in soil structure, which in turn cause a flux of CO2 into the atmosphere. This research was conducted at the Karang Gading and Langkat Timur Laut Wildlife Reserve (KGLTLWR) in North Sumatra, Indonesia. The study focused on six different land covers, namely natural forests, restoration, mixed agriculture, paddy fields, oil palm plantation, and ponds. This study aimed to measure the total carbon stock of mangrove forests that have been converted to other land covers and estimate the level of CO2 flux in the area. A total of three transects and six plots for each land cover were used in this study; for tree biomass, a non-destructive method was used by recording every DBH > 5 cm, and for soil carbon, drilling was carried out, which was divided into five depths in each plot. CO2 flux was measured using an Eosense Eosgp CO2 sensor with the static closed chamber method. The highest carbon stock was found at 308.09 Mg ha−1 in natural forest, while the lowest 3.22 Mg ha−1 was found in mixed agriculture. The highest soil carbon was found at 423.59 MgC ha−1 in natural forest, while the lowest 50.44 MgC ha−1 was found in mixed agriculture dry land. The highest average CO2 flux value of 1362.24 mgCO2 m2 h−1 was found in mangrove restoration and the lowest in ponds was 123.03 mgCO2 m2 h−1. Overall, the research results inform how much carbon stock is lost when converted to other land covers so that it can be used as a reference for policy makers to provide future management of mangrove forests and develop mitigation measurements to reduce carbon emissions.
