Abstract Forest ecosystems are an essential part of the global carbon cycle and constitute a large fraction of the storage of terrestrial carbon. However, climate change may induce shifts in temperature and precipitation. These changes in temperature and precipitation have pronounced consequences for forest growth and carbon sequestration potential...

Iron (Fe) is the fourth most abundant element on earth and represents an essential nutrient for life. As a fundamental mineral element for cell growth and development, iron is available for uptake as ferric ions, which are usually oxidized into complex oxyhydroxide polymers, insoluble under aerobic conditions. In these conditions, the bioavailabili...

... It does, however, react to oxidative and osmotic stress [96]. In a related study using same bacterial consortium with alfalfa (Medicago sativa L.) plant in combination with fertilizer to remediate an oily sludge: soil mixture 30:70 ratio, 63% TPHs were degraded with significant degradation (80%) of n-alkanes (nC13 to nC29) witnessed at day 3. Thus, the mixture has been proven to be efficient in hydrocarbon remediation [97]. Winter rye (Secale cereale L.) was used as the main phyto-remediating plant, while nitrogen fertilizer, alfalfa (Medicago sativa L.), and PGPR strain (Azospirillum brasilense SR80) were used as extra components, either independently or in numerous combinations, to stimulate phytoremediation of oil sludge contaminated soil in vegetative experiments. ...
... Research methods include the percentage of importance of omitted patches (PIOP) [23], the landscape mechanism model [24], the integrated valuation of ecosystem services and tradeoffs tools (InVEST) [25], morphological spatial pattern analysis (MSPA) [26], spatial priority [27] and minimum cumulative resistance (MCR) [28]. In certain areas, cross-ecosystem research has been carried out on mountains [29,30], urban agglomerations [31,32], watersheds [33,34], provincial areas [35,36], urban areas [37][38][39] and county areas [40,41] on the basis of landscape ecological construction theory centered on human social activities. Ecological planning theories focusing on maximizing multiple ecological values were adopted for research into land and marine planning [42,43], forest landscapes [44,45], ecosystem services change in an oasis [46], evaluation of ecologically sensitive areas [47], river bank buffering areas [48] and urban ecological landscapes [49][50][51]. ...
... PGPR may produce siderophores, which are substances characterized by a low molecular weight involved in the chelation process of iron (Fe 3+ ) [182]. When iron is limited in the environment, microbic siderophores allow for the reduction of iron to the soluble form Fe 2+ , which is then released into the plant cell [65,69,183]. PGPR also enhance plant growth by producing very efficient extracellular siderophores, which allow the control of several plant disease by depriving the pathogens of iron nutrition [104]. ...
... Growing at the foot of the snow mountains, the Fuji apple trees of Aksu are irrigating the melting-snow water all year long, and the diurnal temperature in this region is large and there is almost no precipitation all year round as well [16,23]. As a result, there is fructose condensed inside the apples which are commonly known as sugar-sweetened apples. ...
... Studies have indicated that Gaiella played an important role in nitrogen cycling in cultivated farm ecosystems . Bacillus is one of the most important PGPR that promotes plant growth and development by secreting phytohormones (Shahzad et al., 2021), improving nutrient absorption and utilization efficiency (Sun et al., 2021) and stress tolerance (Shahid et al., 2021). Park et al. (2013) showed that B. subtilis strain B4 increased IAA activity by increasing L-tryptophan metabolism to encourage cucumber growth. ...
... The genus Alcea L., a member of Malvaceae family, is perennial herb of Mediterranean with main centers of diversity in the Western Mediterranean Basin and the Middle East. According to RIEDL (1976), 39 species are found in Iran, however, the amount has since been shrunk to 34 because of rearranging taxonomies among them, 15 species are endemic (PAKRAVAN, 2008b;YIN et al., 2021;JIA et al., 2020). Alcea species are mainly yearly, biyearly or perennial, mainly tall-growing hemicryptophytes. ...
... We implemented morphological and molecular methods (inter simple sequence repeat (ISSR)) to decipher the genetic diversity of the H. helix populations in the current work. Plant molecular methods, including molecular markers, enhance our understanding of plant genetic diversity and plant identification (Mondini et al. 2009;Nadeem et al. 2018;Shakoor et al. 2021;Yin et al. 2021). Previously, Etminan et al. (2018) used molecular markers, such as ISSRs and start codon targeted (SCoT) to study the genetic variation within plant species and populations (Etminan et al. 2018). ...
... The study found that immobilizing cells boosted cell-tocell interaction with solubilized hydrocarbon droplets and resulted in fast hydrocarbon uptake. A study by Diaz and colleagues found that immobilizing cells of bacteria enhance crude oil biodegradation rate as that of free-living cells (Dıaz et al. 2002;Shahzad et al. 2020). ...
... The use of bacterial consortium in a combination of fertilizers can improve the oxidative status through improving the soil structure of the soils contaminated with oily sludge. Similar findings were reported by Xiao, Zhou, and Ma (2005), who found increased tolerance and accelerated growth of tall fescue under a hydrocarbon stress environment in soil with 50 mg g −1 of sludge inoculated with PGPR. They concluded that this might be due to the increased rate of degradation of some toxic hydrocarbons in hydrocarbon-contaminated soils because of inoculation of PGPR. ...
... This shows the importance of temperature and precipitation in Eurasia. Recent work has also highlighted the significance of temperature and precipitation to determine the biomass of tree species in Eurasia (Usoltsev et al., 2020a(Usoltsev et al., , 2020b. Responses of Pine trees (Fig. 2) followed the Liebig-Shelford trend because we noticed a decline in foliar biomass due to minimum precipitation. ...
