“…Planted forests typically adopt a rapid investment–return resource use strategy, enabling trees to grow at a faster rate [ 3 ]. Compared to natural forests, the resource use strategy of planted forests is generally more aggressive, largely due to differences in their growth environments, ecological dynamics, and evolutionary backgrounds [ 6 , 24 ]. Compared to natural forests, planted forests have lower species diversity, a simpler structural composition, and are more influenced by human activities and management.…”

Specific leaf area (SLA) and leaf dry matter content (LDMC) are key leaf functional traits commonly used to reflect tree resource utilization strategies and predict forest ecosystem responses to environmental changes. Previous research on tree resource utilization strategies (SLA and LDMC) primarily focused on the species level within limited spatial scales, making it crucial to quantify the spatial variability and driving factors of these strategies. Whether there are discrepancies in resource utilization strategies between trees in planted and natural forests, and the dominant factors and mechanisms influencing them, remain unclear. This study, based on field surveys and the literature from 2008 to 2020 covering 263 planted and 434 natural forests in China, using generalized additive models (GAMs) and structural equation models (SEMs), analyzes the spatial differences and dominant factors in tree resource utilization strategies between planted and natural forests. The results show that the SLA of planted forests is significantly higher than that of natural forests (p < 0.01), and LDMC is significantly lower (p < 0.0001), indicating a “faster investment–return” resource utilization strategy. As the mean annual high temperature (MAHT) and mean annual precipitation (MAP) steadily rise, trees have adapted their resource utilization strategies, transitioning from a “conservative” survival tactic to a “rapid investment–return” model. Compared to natural forests, planted forest trees exhibit stronger environmental plasticity and greater variability with forest age in their resource utilization strategies. Overall, forest age is the dominant factor influencing resource utilization strategies in both planted and natural forests, having a far greater direct impact than climatic factors (temperature, precipitation, and sunlight) and soil nutrient factors. Additionally, as forest age increases, both planted and natural forests show an increase in SLA and a decrease in LDMC, indicating a gradual shift towards more efficient resource utilization strategies.

“…However, its sequestering potential depends on several factors, such as climate, type of soil, crop and vegetation, and management practices (Meena et al, 2020). The carbon stored in soil organic matter (SOM) is affected by the addition of dead plant materials and loss of carbon through respiration, the microbial status process, and soil disturbance (natural and human disturbance) (Koné and Yao, 2021). The carbon capture process can be done by different plant organs: trunks, branches, leaves, flowers, fruits, and roots (Henry et al, 2020).…”

Nowadays, rapid increases in anthropogenic activities have resulted in increased greenhouse gases (GHGs; CO2, CH4, N2O) release in the atmosphere, resulting in increased global mean temperature, aberrant precipitation patterns, and several other climate changes that affect ecological and human lives on this planet. This article reviews the adaptation and mitigation of climate change by assessing carbon capture, storage, and utilization by fruit crops. Perennial plants in forests, fruit orchards, and grasslands are efficient sinks of atmospheric carbon, whereas field crops are a great source of GHG due to soil disturbance, emission of CH4 and/or N2O from burning straw, and field management involving direct (fuel) or indirect (chemicals) emissions from fossil fuels. Thus, there is a need to establish sustainable agricultural systems that can minimize emissions and are capable of sequestering carbon within the atmosphere. Fruit orchards and vineyards have great structural characteristics, such as long life cycle; permanent organs such as trunk, branches, and roots; null soil tillage (preserving soil organic matter); high quality and yield, which allow them to accumulate a significant amount of carbon. Hence, the fruit plants have significant potential to sequester carbon in the atmosphere. However, the efficiency of carbon sequestration by different fruit crops and their management systems may vary due to their growth and development patterns, physiological behavior, biomass accumulation, and environmental factors.

“…Indeed, numerous studies conducted in forest soil ecosystems have provided valuable insights into various microorganisms' genetic diversity and vital roles. These microorganisms include fungi [7,8], bacteria, and archaea [9][10][11], which play crucial roles in processes like nutrient cycling, organic matter decomposition, and soil fertility preservation [12][13][14]. Particularly, arbuscular mycorrhizal fungi are recognized for their roles in enhancing root development, stimulating nutrient cycling, improving soil structure, increasing plant resilience to stress, facilitating the uptake of less mobile ions, and promoting plant community diversity [15].…”

Archaea and bacteria communities play pivotal roles in tropical forest ecosystems’ functioning, especially nutrient cycling, plant phenology, and health. The objective of this study was to explore the diversity of archaeal and bacterial communities in forest soil ecosystem of Côte d’Ivoire and to identify abiotic factors that influence their composition. Using high-throughput amplicon sequencing targeting the V4V5 hypervariable region of the 16S ribosomal RNA gene, we analyzed 22 soil samples taken from the 2 main forest areas of Côte d’Ivoire, namely the semi-deciduous moist forest and the evergreen moist forest, both of which are located in the humid and sub-humid areas of the country. The analysis revealed that the biodiversity at the phyla level was congruent with previous studies. Richness and Shannon diversity indices revealed the dominance of bacteria over archaea in all studied soils. Moreover, the predominant bacterial community consisted of Proteobacteria (29.8%), Acidobacteria (15.5%), and Actinobacteria (14.2%), while the archaeal community was dominated by Thaumarchaeota (1.93%). However, at the genus level, patterns emerged. The most abundant and ubiquitous members at the genus level included Bradyrhizobium, Rhodoplanes, Bacillus (bacteria), and Nitrosophaera (archaea). While bacterial core microbiome members were found in almost all soils, Nitrososphaera genus were selective to sub-humid bioclimate and cropland land use. These patterns were correlated to the soils’ physicochemical characteristics, bioclimate, and land use. This study sheds light on the intricate relationships between abiotic factors and microbial communities in Côte d’Ivoire’s forest soils and helps to identify keys species for future soil management.
