“…Abscisic acid enhances the leaf fall (Yang et al, 2003). Most studies on litter production in tropical forests show a strong association between seasonal litter production and dry season as the peak litter production (Seta & Zerihun, 2018;Gi-weta, 2020;Primo et al, 2021). The litter season pattern generally depends on factors related to leaf shedding (Lian & Zhang, 1998).…”

“…Therefore, apart in tion, such as species abundance and diversity, litter production provides key information about the functioning of a balanced ecosystem (Petraglia et al, 2019). Litter production patterns between ecosystems vary depending on altitude, latitude, soil fertility, standing structure, climate, and tree species composition (Apriyanto et al, 2021;Primo et al, 2021). Apart from these factors, land management of various types of human activities also provides dynamics to litter production and decomposition patterns.…”

Litter is a fragment of aboveground carbon stocks, a vital bridge to the belowground carbon cycle. Land conversion to agricultural purposes will affect litter production. This study aimed to compare the litter production of natural forests with cocoa-based agroforestry systems (AFS) in West Sumatra. Litter production was measured in five different types of ecosystems, namely natural forest (NF), cocoa-rubber-based AFS (CR), multistrata cocoa-based AFS (CM), cocoa-coconut-based AFS (CC), and cocoa monoculture (M). This study is quantitative research with the collection method. The difference in litter production between the five ecosystems observed was tested using ANOVA parametric statistical method. Litter was collected monthly for one year in which litter traps were evenly distributed in each research plot. Ecosystems of NF and M produced the highest annual litter (6.04 Mg ha-1 and 4.65 Mg ha-1 respectively), while CR produced the lowest one (2.52 Mg ha-1). Although this study did not perform comprehensive modeling of decomposition dynamics, the measurement of annual litter production can provide a further understanding of the dynamics of ecosystem carbon, especially in cocoa-based agroforestry.

Combretum leprosum is a plant species with wide distribution in Brazil known as “mofumbo”, standing out in studies associated with its pharmacological and ethnobotanical activity. The medicinal applications of the species are widely reported in the literature, using the bark, leaves and flowers as healing agents. Given the economic, pharmacological and ecological importance, this work aimed to present a systematic review of production, conservation status and knowledge about the species in different fields of knowledge. The literature review was based on seven categories, characterized according to the study area: biological and/or pharmacological activity (32 articles), importance of conservation status (29), botanical aspects (18), phytochemistry (9), geographic distribution (8), foraging (5) and ethnobotanical uses (2). Most of the works address biological and/or pharmacological activity of the species, and its application is focused on antitumor action, treatment against Chagas disease, antinociceptive behavior, antibacterial, antioxidant, anti-inflammatory and antiproliferative action. Among the compounds isolated from C. leprosum with different applications, 3β-6β-16β-trihydroxylup-20(29)-ene stands out, a lupane triterpene isolated from different parts of the plant, associated with different medicinal and therapeutic applications. The species was highlighted in works associated with environmental regeneration, being resistant to different phytophysiognomies and showing tolerance to environments contaminated by heavy metals, being able to represent an important species in reforestation programs and recovery of degraded environments. However, even with the growing number of studies associated with C. leprosum in recent years, the species does not have an assessment regarding its degree of threat, demonstrating the need for research associated with the species and the possible impacts that its representatives may suffer, helping in sustainable development and conservation programs.

Seasonal variation in inorganic N-pool and Net N-mineralization rate was investigated in relation to site characteristics in sub-tropical Sal forest in Central Himalaya, India. Two sites, viz. Fatehpur (FP) located at a latitude of 29°19'23.69''N and longitude of 79°18'05.34''E at 430 m asl and Ranibagh (RB) at a latitude of 29°17'10.03''N and longitude of 79°32'49.19''E at 580m asl were established. Ammonification, nitrification and Nmineralization rates were significantly (p<0.05) affected by site, season, soil depth and their interactions. Total inorganic -N and N-mineralization rates were significantly higher in FP site as compared to RB site. Higher mineralization rates were reported during the summer (7.30±0.17 μg g-1 month-1 and 6.17±0.27 μg g-1 month-1 in FP and RB site, respectively) and lowest rates during the winter season (2.10±0.17 μg g-1 month-1 ) in FP and (1.78±0.18 μg g-1 month-1 in RB site). The variability in mineralization rates may be due to the ecological differences among the sites. Seasons and soil nitrogen content showed positive correlation with Nmineralization rates while site, clay content and C/N ratio showed negative correlation. The soil Nmineralization affects the N release and availability of inorganic-N for supporting the plant growth, thus regulates the N- cycling in forest ecosystems.
