Specific leaf area: a predictive model using dried samples

, 2013
Specific leaf area (SLA; fresh-leaf area/dry mass) describes the amount of leaf area for light capture per unit of biomass invested. The standard protocol is simple; however, it requires recently collected sun-exposed leaves to determine fresh-leaf area,

CSRcalculator: A reproducible framework for understanding plant ecological strategies

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants respond to environmental change is essential for conserving biodiversity and managing ecosystems under climate change. We developed CSRcalculator, an open‐source platform that brings together major competitor, stress‐tolerator, ruderal (CSR) models to make ecological strategy classification accessible, reproducible and scalable.

Effects of Gibberrellic Acid and Salicylic Acid under Salinity on Na+ and K+ Absorbtion and Leaf Characteristic of Two Rapeseed Lines [PDF]

Ikufīziyuluzhī-i Giyāhān-i Zirā̒ī, 2014
This research was carried out on two canola cultivars (Hayola401 and RGS) at Research Laboratory of Islamic Azad University, Borujerd Branch. In this research the effects of GA3 (0.05 Mm), SA (5 M) and NaCl (75, 100 and 150 Mm) on Na+ and K+ changes in ...

Environmental and developmental controls on specific leaf area are little modified by leaf allometry

, 2008
Recent work shows that large leaves tend to require higher biomass investments per unit leaf area than small leaves. As a consequence, specific leaf area (SLA), which is a focus trait for a bulk of physiological and ecological research programs, is ...

Receptive Meaning‐Recall Knowledge of Derivational Morphology Among EFL Learners: A Case for L1‐Population‐Specific Assessment

TESOL Quarterly, EarlyView.
Abstract Vocabulary knowledge plays a crucial role in L2 proficiency, significantly impacting learners' reading comprehension. Although extensive research has explored whether knowledge of base words extends to recognition of derivational forms, results are inconsistent, especially among learners from non‐Indo‐European linguistic backgrounds.

Intraspecific variability rivals interspecific differences in root traits of temperate tree seedlings

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Global change and associated disturbances are increasing the risk of regeneration failure for tree species in temperate forests. Seedlings are particularly vulnerable to water stress due to their shallow root systems, making below‐ground plasticity a potentially key ...

A trait-based integration of competition and abiotic tolerance underlies plant success. [PDF]

New Phytol
Competitive effect and abiotic tolerance show positive associations with species' niche breadth and local dominance. Summary Understanding what determines species' ecological success is a central challenge in ecology. Competitive ability and abiotic tolerance are expected to be strong predictors of species success, yet theory predicts a trade‐off ...

Trait variation driven by tree size more than environment and shows limited translation to species vital rates

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Functional traits are expected to predict vital rates and performance outcomes because they mediate how organisms interact with the environment. However, trait‐based models often have poor predictive power for tree species survival and growth.

Intraspecific Variability in Leaf Functional Traits Reveals Divergent Resource-Use Strategies and Geographic Adaptation in Mediterranean Olive Cultivars from Worldwide Olive Germplasm Bank of Marrakech

Plants
Understanding intraspecific functional trait variability (ITV) is crucial for elucidating plant functional strategies under environmental change. This study investigates the functional responses of 129 Mediterranean olive (Olea europaea L.) cultivars ...
