“…6). A study also revealed higher decomposition rates of Anadenanthera peregrina in the rainy season, which was attributed to enhanced vegetative growth and the nutrient resorption (Valente et al 2023). Moreover, a meta-analysis found a significant % reduction in litter decomposition by 43% depending on drought type and intensity, decomposer community, climate conditions, and litter quality (Ferreira et al 2023).…”

Litter traits and site conditions alter nutrient inputs from deciduous and evergreen forests by influencing litter decomposition processes. Here, we investigated the leaf and stem mass loss rate (MLR) of a deciduous (Tectona philippinensis) and an evergreen (Parashorea malaanonan) tree species and the factors influencing it through an intersite experiment and litterbag method in secondary forests in Lobo, Batangas and Mount Makiling Forest Reserve (MMFR). Variations in initial litter quality (leaf area, specific leaf area (SLA), leaf thickness, vein density), and site factors (light intensity and temperature) were assessed. P. malaanonan has a lower SLA and vein density than T. philippinensis. The leaf and stem MLR were significantly higher in the mixed litter (44.09–57.83%) than that of a single-species litter of either T. philippinensis (28.16–41.83%) or P. malaanonan (33.60–47.66%). The leaf MLR of T. philippinensis was greater when placed in Lobo (where the litter originated) than at a different site (i.e., MMFR). Moreover, leaf litter decomposition was faster in T. philippinensis than in P. malaanonan, particularly during the rainy season. Overall, the study showed that litter decomposition in deciduous and evergreen differed across sites due to variations in litter quality and environmental variables. Keywords: decomposability traits, home-field advantage (HFA), intersite experiment, litter quality, mass loss rate

“…In Brazil, bauxite deposits are typically found over tropical forests in the Amazon and Atlantic Forest regions, as well as on lands already converted for human use, such as pastures and coffee plantations (Cosimo et al, 2021;Komlóssy et al, 2022). Hence, mining activities cause negative impacts on ecosystem functioning due to vegetation cover removal, decreased biodiversity, and changes in soil properties (Borges et al, 2019;Cavalcante et al, 2023;Valente et al, 2023).…”

“…In this context, the construction of mining-associated infrastructures also causes impacts due to soil stabilization actions and the heavy traffic of vehicles (IAI & Wagner, 2016). These impacts lead to the compaction of the soil's surface layer, reduced water infiltration into the soil, and damage to the litter layer, soil seed bank, consequently affecting the natural regeneration of the forest (Bizuti et al, 2022;Economou-Eliopoulos et al, 2022;Valente et al, 2023).…”

The soil seed bank is one of the most important ecological indicators to evaluate and monitor the ecological restoration process of plant communities. We aimed to analyze the influence of two different ecological restoration techniques on the diversity and floristic composition of the soil seed bank and of standing vegetation, in two 4‐year‐old areas under forest restoration around bauxite mining, Southeast Brazil. A total of 30 soil samples were collected in each area (SPN—forest restoration by seedling planting in rows and nucleation techniques between planting rows and SP—forest restoration by seedling planting in rows). The samples were transported to a shade house and evaluated for 6 months, where germinated individuals were counted and identified weekly. A floristic census of shrub/tree species was conducted to assess the diversity of standing vegetation. The results indicated that the soil seed banks of the two areas are floristically similar (predominance of pioneer, herbaceous, and native origin species). The two restoration techniques did not differ in their effects on the species composition of the soil seed bank, mainly due to the restoration age. However, when analyzing the standing vegetation, 38 species were recorded in SPN, while only 20 species were in SP. This result demonstrates that nucleation techniques contributed to the increase in species diversity in SPN. We conclude that combining seedling planting in rows with nucleation techniques (topsoil transposition, direct seeding, and artificial perches) can enhance species diversity in standing vegetation, improve forest functionality, and consequently enhance the potential for forest restoration.

“…The quantity of C stored in the soil is influenced by the equilibrium between the C inputs, such as litterfall and rhizodeposition, and C losses, primarily through decomposition of soil organic matter (SOM) [ 6 , 7 , 8 , 9 , 10 ]. Soil organic carbon (SOC) refers to C stored in the soil in the form of organic matter (OM).…”

This study investigates the soil organic carbon (SOC) and whole tree biomass carbon (C), soil bulk density (BD) as well as changes in these parameters in afforested areas in Latvia. The study covered 24 research sites in afforested areas—juvenile forest stands dominated by Scots pine, Norway spruce and Silver birch. The initial measurements were conducted in 2012 and repeated in 2021. The results show that afforestation mostly leads to a general decrease in soil BD and SOC stock in 0–40 cm soil layer and an increase in C stock in tree biomass across afforested areas with various tree species, soil types, and former land uses. The physical and chemical properties of the soil could explain the differences in changes in soil BD and SOC caused by afforestation, as well as the impact of past land use may have persisted. When comparing the changes in SOC stock with the increase in C stock in tree biomass due to afforestation, taking into account the decrease in soil BD and the resulting elevation of soil surface level, the afforested areas at juvenile development stage can be considered a net C sink.
