Tree‐ring structure determines the temporal coordination between xylem growth and the gain in hydraulic conductivity in the outermost ring

New Phytologist, EarlyView.
Summary The study of seasonal xylem hydraulics has predominantly focused on embolism‐induced losses, whereas growth‐driven increases in hydraulic capacity have received little attention. We assessed the intra‐annual dynamics of xylem formation and gain of conductivity in the current‐year ring of three species with contrasting tree‐ring structure ...

Hydrothermal change regulates spring phenology of different life forms of plants

Global Ecology and Conservation
Plant spring phenology is influenced by multiple climatic variables. Climate warming has significantly advanced spring phenophases over recent decades. However, the differences in responses to climatic variables among various life forms of plants remain ...

Changes in reflectance anisotropy of wheat crop during different phenophases

International Agrophysics, 2017
Abstract The canopy structure of wheat changes significantly with growth stages and leads to changes in reflectance anisotropy. Bidirectional reflectance distribution function characterises the reflectance anisotropy of the targets, which can be approximated.

Ecological divergence in the silver moss Bryum argenteum: developmental, ontogenetic and life‐history trait variations across contrasting tropical ecosystems

Plant Biology, EarlyView.
Ecotypes of the cosmopolitan moss Bryum argenteum differ markedly in growth, reproductive timing, and allocation across contrasting tropical ecosystems. These patterns reveal strong environment‐ and sex‐dependent life‐history strategies, highlighting the species as a model for studying ecological divergence in bryophytes.

Seasonal diet variation, preferences and availability of resources consumed by Sturnira lilium (É. Geoffroy St.-Hilaire, 1810) (Chiroptera: Phyllostomidae) in Brazilian seasonal deciduous forest

Anais da Academia Brasileira de Ciências, 2021
Sturnira lilium is a frugivorous bat that is known for its high consumption of Solanaceae fruits. We captured S. lilium, using mistnets, to study its diet and diet seasonal variation in a seasonal deciduous forest in southern Brazil. We also investigated

Parameterization of an ecosystem light-use-efficiency model for predicting savanna GPP using MODIS EVI [PDF]

, 2014
© 2014 Elsevier Inc. Accurate estimation of carbon fluxes across space and time is of great importance for quantifying global carbon balances. Current production efficiency models for calculation of gross primary production (GPP) depend on estimates of ...

American beech leaf‐litter leachate chemistry: Effects of geography and phenophase

Journal of Plant Nutrition and Soil Science, 2018
AbstractThe decomposition of broadleaved tree leaves can contribute a substantial amount of energy to forested watersheds via dissolved organic matter (DOM), nutrients, and biological activity. Less is known about how these inputs may vary within a single tree species that is known to have two genetically distinct and geographically separate ...

Internal physiological drivers of leaf development in trees: Understanding the relationship between non‐structural carbohydrates and leaf phenology

Functional Ecology, Volume 40, Issue 5, Page 1151-1164, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology is crucial for understanding plant growth and climate feedback. It affects canopy structure, surface albedo, and carbon and water fluxes. While the influence of environmental factors on phenology is well‐documented, the role of plant intrinsic factors ...

Variations in C:N:P Stoichiometry and Non-Structural Carbohydrates in Different Parts of Pomelo (Citrus maxima) Flowers at Three Phenophases

Horticulturae
Carbon (C), nitrogen (N) and phosphorus (P), and non-structural carbohydrates (NSCs) are basic nutrients and energy sources for flower development. In this study, the morphological traits, C, N, P, and NSC concentrations, and C:N:P ratios in pistil ...
