Changes in Plant Rhizosphere Microbial Communities under Different Vegetation Restoration Patterns in Karst and Non-karst Ecosystems [PDF]

Scientific Reports, 2019
AbstractUnderstanding how patterns of recovery and geological conditions affect microbial communities is important for determining the stability of karst ecosystems. Here, we investigated the diversity and composition of microorganisms in karst and non-karst environments under natural restoration and artificial rehabilitation conditions.

Ecological and genomic variation in ectomycorrhizal fungal exploration types

New Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EMF) produce mycelia with variable extension and complexity, which can be classified according to soil ‘exploration types’ (ETs). ETs have received attention as one of the few mycorrhizal trait frameworks, but without an empirical classification of ET functional diversity and environmental preferences, understanding and ...

Long‐term effects of clear‐cutting forestry on ectomycorrhizal fungi in boreal forest

New Phytologist, EarlyView.
Summary Clear‐cutting is detrimental to ectomycorrhizal fungi in a short time perspective, but long‐term effects on species richness and community composition are uncertain. To evaluate ecological sustainability of rotation forestry, we examined to what extent communities similar to those in old forests develop within the time frame of a rotation ...

Intra‐annual transfer of hydrogen and oxygen isotopic signals from water and sugar precursors to tree rings: Processes and mechanisms

New Phytologist, EarlyView.
Intra‐annual radial growth of beech and spruce in 2021 and 2022. Summary The oxygen (δ18O) and hydrogen (δ2H) isotope compositions of leaf and xylem water shape tree‐ring isotope baselines, while the fraction of sugars undergoing isotopic modification downstream of leaves (fO, fH) determines the dominant hydrologic signal.

Temperate tree species show cross‐tolerance to heat, drought, and late spring‐frost stress

New Phytologist, EarlyView.
Significant cross‐tolerance of leaf traits to heat, drought and late spring‐frost were found. (a) Turgor loss point vs lethal spring‐frost temperature. (b) Heat thermal threshold temperature vs lethal spring‐frost temperature. (c) Heat thermal threshold temperature vs turgor loss point.

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

Plant, Cell &Environment, EarlyView.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...

Water Availability and Hydraulic Strategies Control Leaf Thermoregulation and Damage During Heat Stress and Recovery in Temperate Tree Species

Plant, Cell &Environment, EarlyView.
Abstract Heatwaves are intensifying worldwide, often coinciding with high vapour pressure deficit (VPD) and soil drought. Yet, how temperate tree species tolerate these combined stresses remains elusive. Using single‐tree gas‐exchange chambers, we examined the response of leaf gas exchange and thermoregulation of three broadleaved tree species to a ...

Characteristics and evolutionary process of low-mature paleo-subsurface rivers in carbonate sequences and controls on hydrocarbon accumulation in the northern Tarim Basin, NW China

Frontiers in Earth Science
Paleo-subsurface rivers can serve as high-quality reservoir spaces for hydrocarbon accumulation within the carbonate sequence stratigraphy. However, the characteristics and evolutionary process of the typical low-mature paleo-subsurface rivers are rarely
