Vegetation fine-tunes aridity thresholds in soil biodiversity and function worldwide
AimsPlant-soil interactions regulate the response of terrestrial ecosystem to climate change. Recent work suggests that aridity thresholds control...

Aridity-driven divergence in soil microbial necromass carbon in alpine grasslands of the Tibetan Plateau
Soil microbial necromass carbon (MNC) contributes to the long-term stability of soil organic carbon (SOC). However, the response of MNC across...

Hydraulic vulnerability difference between branches and roots increases with environmental aridity
The vulnerability of plant xylem to embolism can be described as the water potential at which xylem conductivity is lost by 50% ( P 50 ). According to...

Hotspots of biogeochemical activity linked to aridity and plant traits across global drylands
Perennial plants create productive and biodiverse hotspots, known as fertile islands, beneath their canopies. These hotspots largely determine the...
-
Divergent responses of nitrogen availability to aridity in drylands
PurposeDrylands are generally drought-stressed and have low soil fertility. While negative effects of drought on vegetation productivity are...

Scaling up tree growth to assess forest resilience under increasing aridity: the case of Iberian dry-edge pine forests
ContextMediterranean managed dry-edge pine forests maintain biodiversity and supply key ecosystem services but are threatened by climate change and...
-
Moisture thresholds for ignition vary between types of eucalypt forests across an aridity gradient
ContextQuantifying spatial and temporal variations in landscape flammability is important for implementing ecologically desirable prescribed burns...
-
Belowground plant traits and their ecosystem functions along aridity gradients in grasslands
Ecosystem responses to environmental change are usually studied solely using aboveground (usually leaf) traits. However, belowground plant traits,...
-
Recent evolution of flowering time across multiple European plant species correlates with changes in aridity
Ongoing global warming and increasing drought frequencies impact plant populations and potentially drive rapid evolutionary adaptations. Historical...

Relationships Between Soil Microbial Diversities Across an Aridity Gradient in Temperate Grasslands
Soil microbes assemble in highly complex and diverse microbial communities, and microbial diversity patterns and their drivers have been studied...

Environment-dependent and intraspecific variations in leaf and size traits of a native wild olive (Olea europaea L.) along an aridity gradient in Morocco: a functional perspective
Understanding plant adaptive strategies to aridity is crucial for ecological research, particularly in the current context of climate change and...

Aridity-driven changes in structural and physiological characteristics of Buffel grass (Cenchrus ciliaris L.) from different ecozones of Punjab Pakistan
Cenchrus ciliaris L. is a perennial grass that can grow in a diverse range of habitats including challenging deserts. The purpose of the study was to...

Aridity, but not disturbance, reduces the specialization and modularity of plant–insect herbivore interaction networks in Caatinga dry forest
AbstractPlant–herbivore networks comprise over 40% of the global biodiversity and are negatively impacted by habitat loss and fragmentation. However,...

Contrasting responses of plant above and belowground biomass carbon pools to extreme drought in six grasslands spanning an aridity gradient
Background and aimAs global climate change intensifies, the frequency and duration of extreme droughts are predicted to increase, resulting in...
-
Habitat aridity as a determinant of the trade-off between water conservation and evaporative heat loss in bats
The maintenance of water balance in arid environments might represent a formidable challenge for Chiroptera, since they have high surface-to-volume...

Phenotypic differentiation and diversifying selection in populations of Eruca sativa along an aridity gradient
BackgroundThe aridity gradient in the eastern Mediterranean offers an opportunity to investigate intra-specific genetic differentiation and local...
-
Widespread synchronous decline of Mediterranean-type forest driven by accelerated aridity
Large-scale, abrupt ecosystem change in direct response to climate extremes is a critical but poorly documented phenomenon
1 . Yet, recent increases in...

Effects of grazing on plant communities and successional processes vary along an aridity gradient at a northern temperate grassland
The intermountain grasslands of North America reach their most northern geographic extent in interior British Columbia’s Cariboo-Chilcotin region....
-
Chemosynthetic and photosynthetic bacteria contribute differentially to primary production across a steep desert aridity gradient
Desert soils harbour diverse communities of aerobic bacteria despite lacking substantial organic carbon inputs from vegetation. A major question is...

Increasing relative abundance of C4 plants mitigates a dryness-stress effect on gross primary productivity along an aridity gradient in grassland ecosystems
PurposeImpacts of dryness stress (i.e., low soil moisture [ SM ] and high vapor pressure deficit [ VPD ]) on gross primary production ( GPP ) have...
