Effects of environmental factors on the phenotypic traits and seed element accumulation of wild Elymus nutans in Tibet

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Jan. 13, 2025

Soil nutrients and meteorological conditions are pivotal environmental factors influencing plant growth development. This study systematically analyzes how soil influence the phenotypic seed production of wild Elymus nutans in Tibet. These critical ecological determinants, this research seeks to unveil complex diverse adaptation mechanisms species. The encompasses ten counties within Tibet Autonomous Region, with sampling points distributed across seven distinct environments. By evaluating root nutrient levels, collecting data, analyzing characteristics elemental composition at various points, assesses adaptability under conditions. Cluster analysis categorized 25 samples into four groups, each exhibiting significant differences height leaf length. Correlation revealed a negative correlation between point elevation NH₄⁺, total phosphorus, available phosphorus content, while positive was observed pH levels. Meteorological variables—including temperature, humidity, precipitation—significantly influenced phenotypes seeds. ammonium nitrogen, vital for nutans, their deficiency has impact on overall growth. Environments characterized by high altitude, aridity, intense radiation constrain Climatic altering environment, where quality plays role determining interact collectively ecosystem.

Unraveling the Impact of Diverse Vegetative Covers on Soil Carbon Fractions

Sustainability, Journal Year: 2025, Volume and Issue: 17(3), P. 1080 - 1080

Published: Jan. 28, 2025

Evaluating SOC lability is crucial for sustainable agriculture policies and environmental quality. This study assessed the impact of well-stocked forest cover on pools compared to shrubby soil. Geo-referenced soils under Red pine (Pinus brutia), Black nigra), Cedar (Cedrus libani), Fir (Abies cilicia), Juniper (Juniperus excelsa), Oak (Quercus L.), Carob (Ceratonia siliqua), degraded shrubs were collected from a depth 0 30 cm in Seyhan River Basin, Mediterranean Turkey. The analysis soil organic carbon (SOC), AC (active carbon), PC (passive carbon) analyzed understand management across diverse vegetation types. forests have highest (27.98 g/kg) (27.35 g/kg), followed by (SOC: 27.64 g/kg, PC: 27.05 26.44 25.85 g/kg). Shrubby areas lowest (4.06 (3.61 had CLI (1.16), suggesting relatively higher proportion labile than other forests. CPI indicates greater storage capacity (1.09) shrublands (0.18), with also having CMI (0.83). findings emphasize critical role forests, especially sequestration climate change mitigation within Basin

Warmer Climate Reduces the Carbon Storage, Stability and Saturation Levels in Forest Soils

Earth s Future, Journal Year: 2025, Volume and Issue: 13(2)

Published: Jan. 30, 2025

Abstract Forest soils store about one‐fifth of the global terrestrial biosphere carbon stock. However, our understanding how soil geochemical, plant and microbial factors regulate forest organic (SOC) storage, stability, saturation levels remains limited. Here, we conducted a sampling campaign across 5000‐km natural transect in China, measuring climate, geochemical SOC fractions with varying stability. Additionally, compiled data set major biomes. Our field survey synthesis consistently demonstrate that warmer climates not only reduce content labile particle matter (POM), but also decrease typically stable mineral‐associated (MAOM), leading to significant decline total storage. promote crystallization Fe/Al oxides, which decreases formation efficiency oxide associated complexes. Consequently, mineralogical level declines from boreal forests (37%) tropical (25%). findings underscore that, beyond well‐established climate impacts, properties play pivotal role shaping composition latitudes. This highlights colder regions harbor larger more pools, ongoing warming shift could potentially lead storage its capacity mitigate change.

Historical Variation in Carbon Fractions in Permafrost Peatland and Its Effects on Peatland Carbon Pool

Land Degradation and Development, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 4, 2025

ABSTRACT Permafrost peatlands store high amount of soil carbon. These developed on permafrost layers, which are being endangered increasingly by climate change and wildfires. However, limited data exist the variation in carbon fractions their effects stability peatland pools, despite that widely used other ecosystems. Here, we considered peat soils consist undecomposed plant litter separated these into five fractions: macro residue (MPRC), coarse particulate organic (cPOC), free (fPOC), occluded (oPOC), mineral‐associated (MAOC). We analyzed historical over past 700 years pool Hongtu (HT, northern Great Khingan Mountains, China). Our results showed MPRC comprised 66.7% ± 7.6% pool, whereas oPOC MAOC accounted for less than 1%. Notably, fPOC, represented 15.6% 6.5% total carbon, had a aromatic content. It may serve as an important stable fraction pool. Over years, decrease proportion increase proportions cPOC fPOC have resulted significant increases both content aromaticity. Warm/dry conditions high‐intensity fires reduced accumulation rates (ARs) while increasing those cPOC. The HT availability mineral elements ARs approximately 0.01 g m −2 yr −1 . This was strongly influenced regional dust deposition. Cold climates intense caused deposition, also increased ARs.
