Ecosystem engineers in rivers: An introduction to how and where organisms create positive biogeomorphic feedbacks [PDF]
, 2017 Ecosystem engineers substantially alter physical flow characteristics and shape a river's form and function. Because the recurrence interval of geomorphic processes and disturbances in rivers commonly match the temporal scale of plants’ life cycles or ...

Plant, Cell &Environment, EarlyView.ABSTRACT Extreme heat can push plants beyond their thermal safety margin (TSM) if maximum leaf temperature (Tleaf_max) exceeds leaf critical temperature (Tcrit). The TSM is potentially useful for assessing heat vulnerability across species but needs further validation, so we exposed 50 tree/shrub species in controlled glasshouses to a 6‐day heatwave ...

, 2014 The shade avoidance syndrome (SAS) is one of the best-studied forms of plant phenotypic plasticity. The suite of SAS responses enables plants to accurately match their phenotype to the light conditions determined by neighbouring plants, especially the ...

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 ...

Gap effects on leaf traits of tropical rainforest trees differing in juvenile light requirement
, 2014 The relationships of 16 leaf traits and their plasticity with the dependence of tree species on gaps for regeneration (gap association index; GAI) were examined in a Neotropical rainforest. Young saplings of 24 species with varying GAI were grown under a

The art of being flexible: how to escape from shade, salt and drought: The art of being flexible: how to excape from shade, salt and drought [PDF]
, 2014 Environmental stresses, such as shading of the shoot, drought, and soil salinity, threaten plant growth, yield, and survival. Plants can alleviate the impact of these stresses through various modes of phenotypic plasticity, such as shade avoidance and ...

Non-structural carbohydrates and leaf ecophysiology in tropical and temperate forests
, 2022 Increasing atmospheric CO2 concentration has led to an increment in forest biomass because of both an inhibition in photorespiration rates, and an increase in photosynthesis main substrate, atmospheric CO2.

Plant, Cell &Environment, EarlyView.ABSTRACT Drought‐induced tree mortality underscores the need for improved physiological models to predict tree responses to water stress. We employed a hysteresis modelling approach analyzing diel water absorption and desorption cycles to understand drought‐induced shifts in physiological thresholds.

Lack of Hydraulic Acclimation in Response to Multiple Droughts and Recovery
Plant, Cell &Environment, EarlyView.ABSTRACT Human‐caused climate change is expected to bring more frequent and extended droughts with shorter wet periods of relief in between for many regions of the world. Critical knowledge gaps remain around the extent to which tree species can acclimate physiologically to repeated droughts.
