Integrated transcriptome and metabolome analysis reveals molecular responses of spider to single and combined high temperature and drought stress.

High temperature and drought are abiotic stresses restricting many arthropods' survival and growth. Wolf spiders are poikilothermic arthropods that are vital in managing insects and pests. Nonetheless, investigating changes in spiders under temperature and drought stress are limited, especially at the molecular and gene expression levels.

Warming Shapes and -Type Denitrifier Communities and Stimulates NO Emission in Acidic Paddy Soil.

Warming strongly stimulates soil nitrous oxide (NO) emission, contributing to the global warming trend. Submerged paddy soils exhibit huge NO emission potential; however, the NO emission pathway and underlying mechanisms for warming are not clearly understood. We conducted an incubation experiment using N to investigate the dynamics of NO emission at controlled temperatures (5, 15, 25, and 35°C) in 125% water-filled pore space.

[NO Consumption Ability of Submerged Paddy Soil and the Regulatory Mechanism].

A large number of researches showed that the NO negative emissions from flooding paddy fields, peatlands and other wetlands ecosystem were frequent and considerable, which is of great significance on alleviating the greenhouse gas effect. However, there are few reports about the transformation and microbial mechanism of NO between atmosphere and paddy soil. The slurry of surface paddy soil (0-5 cm) was incubated in laboratory conditions, and the effect of enhanced NO concentrations in headspace on the NO consumption capacity of submerged paddy soil and the response of gene abundance were explored.

[Concentrations of different carbon and nitrogen fractions in rhizosphere and non-rhizosphere soils of typical plant species in mountainous area of southern Ningxia, Northwest China].

Taking the rhizosphere and non-rhizosphere soils of five typical plants Agropyron cristatum, Artemisia frigida, Pseudoraphis bungeana, Thymus mongolicus, and Artemisia sacrorum in a mountainous area of southern Ningxia as test objects, this paper studied their C and N forms contents. The C and N forms contents in the rhizosphere and non-rhizosphere soils differed with plant species. In the rhizosphere soil of A.
