Functional trait response to aridity based on leaf trait network analysis in the Hexi Corridor, China [PDF]

BMC Plant Biology
Background Aridity acts as a strong environmental filter for plants and is predicted to intensify in the future, resulting in changes to leaf functional traits.

Belowground soil and vegetation components change across the aridity threshold in grasslands

Environmental Research Letters, 2023
Grassland ecosystem functions are affected by global climate change and increasing aridity. Belowground components of soil and vegetation, such as specific root length, belowground biomass and soil organic carbon are important for maintaining these ...

Sexual Reproduction Is Not Responsible for Caragana Shrub Encroachment in Grasslands

Agronomy, 2023
Shrubs tended to increase their abundance as climatic aridity and grazing intensity increased in the Inner Mongolian grassland. Increasing shrub abundance was believed to be due to enhanced reproduction.

Asymmetric response of above- and below ground biomass of C3- and C4-dominated grasslands to aridity

Journal of Water and Climate Change, 2023
Assessing the dynamics of grassland functioning is critical for gaining an understanding of their feedback on rising aridity. In attempting to understand the response of grassland ecosystem functioning to aridity, the (i) relationships between biomass ...

Soil pqqC-harboring bacterial community response to increasing aridity in semi-arid grassland ecosystems: Diversity, co-occurrence network, and assembly process

Frontiers in Microbiology, 2022
Aridity is increasing in several regions because of global climate change, which strongly affects the soil microbial community. The soil pqqC-harboring bacterial community plays a vital role in soil P cycling and P availability.

Aridity Threshold Induces Abrupt Change of Soil Abundant and Rare Bacterial Biogeography in Dryland Ecosystems

mSystems, 2022
Aridity, which is increasing worldwide due to climate change, affects the biodiversity and functions of dryland ecosystems. Whether aridification leads to gradual (or abrupt) and systemic (or specific) changes in the biogeography of abundant and rare ...

Spatiotemporal changes in aridity of Pakistan during 1901–2016 [PDF]

Hydrology and Earth System Sciences, 2019
The changing characteristics of aridity over a larger spatiotemporal scale have gained interest in recent years due to climate change. The long-term (1901–2016) changes in spatiotemporal patterns of annual and seasonal aridity during two major crop ...

Evaluation of Grid-Based Aridity Indices in Classifying Aridity Zones in Iraq [PDF]

Nature Environment and Pollution Technology
In this study, the aridity index (AI) based on gridded climate data was validated for defining aridity and classifying aridity zones in Iraq through comparison with the results obtained by the station-based aridity index. Gauge-based gridded climate data

Aridity drives clinal patterns in leaf traits and responsiveness to precipitation in a broadly distributed Australian tree species

Plant-Environment Interactions, 2023
Aridity shapes species distributions and plant growth and function worldwide. Yet, plant traits often show complex relationships with aridity, challenging our understanding of aridity as a driver of evolutionary adaptation.

Assessment of spatial distribution of aridity indices in Raya valley, northern Ethiopia

Applied Water Science, 2018
Aridity is a risk with the threat of desertification because of erratic precipitation and prolonged droughts. Aridity indices are often used for the climate-based land classification and monitoring droughts.
