Precipitation legacies reshape clonal demography associated with early productivity recovery in a semi-arid typical steppe

Ecological Indicators
Altered precipitation can leave persistent legacies after climatic anomalies cease, yet whether these legacies are retained in plant regenerative organs and linked to subsequent productivity recovery remains unclear.

Increased light-use efficiency sustains net primary productivity of shaded coffee plants in agroforestry system

, 2017
In agroforestry systems, shade trees strongly affect the physiology of the undergrown crop. However, a major paradigm is that the reduction in absorbed photosynthetically active radiation is, to a certain extent, compensated by an increase in light-use ...

Canopy‐scale VPD reduction in a mature forest alters stomatal response to soil drought in Pinus sylvestris L.

New Phytologist, EarlyView.
In a mature Scots pine forest (Pfynwald, Switzerland), canopy vapor pressure deficit (VPD)a was reduced with a misting system (a) and combined with a throughfall‐exclusion roof that imposed soil drought (b). Under the roofs (c), trees at ambient VPD closed their stomata steeply as predawn water potential (ΨPD) fell, reaching closure around −1.2 MPa ...

Drought affects Fe deficiency‐induced responses in a purple durum wheat (Triticum turgidum subsp. durum) genotype

Plant Biology, EarlyView.
Combined Fe deficiency and drought in durum wheat trigger interactive responses: drought suppressed root Fe uptake regardless of Fe availability, and both stresses altered phytosiderophore release, ABA level and Fe transporter gene expression, revealing a trade‐off between water and Fe. Abstract Iron (Fe) is essential for plants and humans, with over 2

Time‐series multi‐omics analysis of micronutrient stress in Sorghum bicolor reveals iron and zinc crosstalk and regulatory network conservation

Plant Biology, EarlyView.
Overlap between Fe and Zn responsive gene regulatory networks (GRNs) were found, indicative of micronutrient crosstalk, and conservation of root and leaf GRNs and genes suggests strong constraint on homeostasis networks in plants. Abstract Micronutrient stress impacts growth, biomass production, and grain yield in crops.

Impacts of reclamation approaches on plant establishment in an arid environment during copper mine revegetation

Restoration Ecology, EarlyView.
Abstract Introduction Revegetation using native vegetation is a commonly used technique to reclaim landscapes degraded by mining activities. Revegetation efforts in the arid Southwestern United States face physical, geochemical, hydrological, and biological challenges unique to drylands.

Long‐term effects of annual mowing on plant diversity, community composition, and temporal stability in wet grasslands

Restoration Ecology, EarlyView.
Abstract Introduction Wet grasslands and fens are biodiversity‐rich ecosystems whose structure and functioning are shaped by disturbance, productivity, and hydrological conditions. Their persistence depends on management. Although mowing is widely used to maintain these habitats, its long‐term effects on species diversity and community composition ...

Nurse structures effectively improve the performance of restoration plantings: a systematic review

Restoration Ecology, EarlyView.
Abstract Introduction Tree planting for ecosystem restoration often occurs on disturbed, degraded, or former agricultural sites, where seedlings face harsh conditions like sun exposure, drought, wind, frost, and browsing, which can lead to poor performance.
