Arid and semi-arid regions account for about 40% of the world's land surface area, are most sensitive areas to climate change, leading a dramatic expansion arid in recent decades. Ephemeral plants crucial herbs this area very but it is still unclear which factors can determine distribution ephemeral how responds future change across globe.Understanding impact on plant sustainable biodiversity conservation.This study explored potential three types (cold desert, hot deciduous forest) global scale using MaxEnt software. We used species occurrence data 30 environmental scientific collections.Our results showed that (1) average value under receiver operating curve (AUC) each was higher than 0.95, indicating model's simulation accuracy good; (2) distributions cold desert forest were mainly determined by soil pH annual mean temperature; key factor determines precipitation driest month; (3) increased one-third scenarios; suitable Anastatica hierochuntica decreased more half scenarios, Trigonella arabica scenarios. In forests, Crocus alatavicus nearly nine-tenths Gagea filiformis 75% scenarios.The different ecosystems closely related their specific adaptation strategies. These contribute comprehensive understanding pattern some ecosystems.

Abstract Background Rodents play an important role in the life cycle of ixodid and argasid ticks, particularly as hosts larvae nymphs. The great gerbil ( Rhombomys opimus ), preferred prey item several carnivores (e.g. red fox marbled polecat), is dominant rodent species Gurbantunggut Desert northwestern China. aim this study was to investigate tick associated with different habitat gerbils, including wildlife livestock. Methods During 2018–2023, ticks were removed from 326 two foxes Vulpes vulpes three polecats Vormela peregusna 35 pastured sheep Ovis aries one long-eared desert hedgehog Hemiechinus auritus ) Desert. Ticks identified according standard morphological keys. Then, they further analyzed by molecular phylogenic methods based on mitochondrial markers, 16S rDNA cytochrome c oxidase subunit I COI genes. Results A total 889 collected, representing five species.

Shallow groundwater is an important water source for Haloxylon ammodendron (H. ammodendron). The accurate estimation of evapotranspiration (ETg) from great significance the cycle and maintenance ecological stability. Using a combination balance method level fluctuation (WTF), components (precipitation, soil moisture, depth, Bowen ratio meteorological data) in desert–oasis transition zone were continuously monitored 2015 to 2018 ETg was estimated results showed that closed degree specific energy after data screening higher, annual actual (ETa) value could be reliably calculated at 260.87 mm. As main contributor consumption growing season, latent heat accounted 70.16~91.86% balance. Precipitation had no significant impact on H. vegetation growth, precipitation season 59.44% ETa. depth study area decreased yearly growth vegetation. Although greater than 9 m, ETg, as part balance, found participate process brought about by due strong root system supporting capillary soil. ETa 244.32 mm, contribution rate high 74.78% or approximately 182.35 After verified using WTF, R 0.96, RMSE range 1.5931~4.5706, bias −0.15~0.11, IOA 0.95. accuracy model high, relatively accurate. can applied obtain estimations provide theoretical guidance scientific basis local resource management protection.

The desert ecosystem is an important ecological barrier to prevent desertification and maintain the stability of arid zone regional security. degree change species composition pioneer during early spring recovery community can be used as indicators ecology predict subsequent in spring. Rodents serve engineers through their behavior, they influence biological communities. In this study, we analyzed correlations between soil physicochemical properties, assembly, plant diversity microbial areas disturbed by gerbils (RD) those not (CK) with ephemeral plants comprehensively evaluated quality (SQI) sustainability (SI). results showed following: (1) nutrients within two different were significantly owing disturbance, biodiversity RD was greater than that CK, but there low homogeneity; (2) There significant differences different; (3) correlation analysis assembly niche width higher more affected deterministic factors, while CK opposite; (4) analytical SI SQI smaller CK. conclusion, disturbance rodents enhances detrimental long-term development Therefore, it explore rational use relationships "complement strengths weaknesses," provide a theoretical basis for future reasonable control areas, improve regions.

Microbial activity plays a crucial role in upholding the functional stability of vegetation–soil ecosystems. Nevertheless, there exists paucity studies concerning impact sand-fixing vegetation (Haloxylon ammodendron) on structure and attributes soil microbial communities. We employed Illumina high-throughput sequencing PICRUSt2 prediction technology to investigate characteristics bacterial community structure, diversity, metabolic functions an artificial H. ammodendron forest, RDA analysis Mantel test were used reveal main environmental factors affecting ecological The findings revealed significant increase principal nutrient contents (organic matter, total nitrogen, phosphorus) forest compared mobile dune soil, while reduction 17.17% surface water content was observed. exhibited enhancement diversity richness index bacteria. Specifically, Actinobacteria (24.94% ± 11.85%), Proteobacteria (29.99% 11.56%), Chloroflexi (11.14% 4.55%) emerged as dominant phyla, with displaying significantly higher abundance soil. analyses that predominant secondary bacteria carbohydrate metabolism, amino acid metabolism cofactors vitamins. Additionally, tertiary pathways greater relation enzyme function, nucleotide energy antibiotics. results demonstrated SOM, AK, pH collectively accounted for 82.4% cumulative contribution, influencing community. Moreover, function primarily relied five factors, namely TN, pH, EC. This study advances our understanding structural changes communities during reclamation sandy land through establishment forests.

Using fly ash as the main matrix for plant ecological restoration is effective constructing a sustainable and environment. The relevant properties of functional soil change due to different factors. Based on orthogonal experiment pot oat grass, was used material soil. Afterward, MX (large granules dispensing certain nutrients), SJJXWS (a water-retaining agent), AF nutrient conditioner) additives were added study physical, chemical, agronomic soil, such emergence rate weight plants. results showed high pH conductivity implying alkaline soils with salinity. contents organic matter available phosphorus potassium relatively high, indicating its content. Further analysis revealed that key factor affecting soil's electrical evaporation, thus, corresponding rate, weight, other related indicators. influence each indicators arranged in order conditioner). optimum additive ratio 0.45 t·hm-2 MX, 0.12 SJJXWS, 1.65 AF. this provide theoretical basis further development cycle purposes.
