Aridity Threshold Induces Abrupt Change of Soil Abundant and Rare Bacterial Biogeography in Dryland Ecosystems [PDF]
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 ...

Aridity thresholds of soil microbial metabolic indices along a 3,200 km transect across arid and semi-arid regions in Northern China [PDF]
Soil microbial processes are crucial for understanding the ecological functions of arid and semi-arid lands which occupy approximately 40% of the global terrestrial ecosystems.

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

Unravelling depth-dependent pedoclimatic controls on measurable soil organic carbon fractions across climatic gradients in Australian agricultural soils [PDF]
Soil organic carbon (SOC) accumulation and persistence are predominantly governed by an intricate interplay among biomass inputs, microbial activity, and soil mineralogy, all of which are strongly modulated by climate-driven moisture availability ...

Ecological mechanisms underlying aridity thresholds in global drylands [PDF]
Abstract With ongoing climate change, the probability of crossing environmental thresholds promoting abrupt changes in ecosystem structure and functioning is higher than ever. In drylands (areas where it rains <65% of what could be potentially evaporated), recent research has shown how the crossing of three aridity thresholds [at aridity (1 ...

Global ecosystem thresholds driven by aridity [PDF]
Thresholds of aridity Increasing aridity due to climate change is expected to affect multiple ecosystem structural and functional attributes in global drylands, which cover ∼45% of the terrestrial globe. Berdugo et al.

Using Lancaster Index to Analyse of the Sand Dunes Activity in Arid lands and Sensitivity Analysis of the Factors Affecting it (Case Study: Buin-Zahra City) [PDF]
Wind erosion and sand dunes mobility has adverse environmental consequences. Identification of factors affecting sand dunes mobility and predicting their future status is essential to control the desertification process.

How does water yield respond to mountain pine beetle infestation in a semiarid forest? [PDF]
Mountain pine beetle (MPB) outbreaks in the western United States result in widespread tree mortality, transforming forest structure within watersheds. While there is evidence that these changes can alter the timing and quantity of streamflow, there is ...
