Leaf C:P ratio as a universal indicator of photosynthesis in subtropical woody species: Stoichiometric thresholds and metabolic trade‐offs

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric ratios of carbon (C), nitrogen (N) and phosphorus (P) serve as important indicators for assessing nutrient balance in forest ecosystems, but their relationships with photosynthetic dynamics require deeper characterization.

Growth dynamics of two bean varieties (Phaseolus vulgaris L.). l. Growth analysis by fixed periods Dinámica de crecimiento de dos variedades de frijol (phaseolus vulgaris L.) l. análisis de crecimiento por periodos fijos

open access: yesAgronomía Colombiana, 1993
Inthe vegetative phase of growth in bean (Phaseolus vulgaris L.), the dry matter gain depends on the physiological behavior and growth habit of the bean plant. The Growth process in relation to growth type were evaluated in the present study. The purpose

Facilitation influences when trees grow, but not growth rate in a dry temperate forest

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Accurately predicting the role of forests in the global carbon cycle requires a detailed understanding of the factors mediating the timing and magnitude of radial stem growth. While weather conditions and topo‐edaphic factors play a critical role in mediating short‐term

Soil legacy effects on a temperate tree species depend on the mycorrhizal types and phylogenetic distance of the conditioning trees

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Associations of trees with arbuscular mycorrhizal (AM) and ectomycorrhizal (EcM) fungi often shape distinct microbial communities in soils. Whether this distinction can create different soil legacies and to what extent such legacies are correlated to phylogenetic ...

Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

open access: yesJournal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

ESTIMATIVA DA ÁREA FOLIAR DE JUAZEIRO POR DIMENSÕES LINEARES DO LIMBO FOLIAR

open access: yesRevista Verde de Agroecologia e Desenvolvimento Sustentável, 2008
Com o objetivo de obter equações que, através de parâmetros lineares dimensionais das folhas, permitisse a estimativa da área foliar de juazeiro, estudaram-se relações entre a área foliar real e parâmetros dimensionais do limbo foliar, como o comprimento

Offspring performance does not explain oviposition preference in the leafminer Stigmella sorbi (Lepidoptera: Nepticulidae): a tri‐trophic perspective

open access: yesInsect Science, EarlyView.
We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.

Robust estimation of key leaf traits from reflectance spectroscopy of herbarium specimens

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Community‐wide efforts to digitize herbarium specimens have facilitated novel uses of specimen data across scales. However, the need for destructive sampling has prevented large‐scale examination of foliar functional traits. We demonstrate that nondestructive reflectance spectra are an effective tool for estimating leaf traits from herbarium ...

Determinação da área foliar de macadâmia a partir de dimensões lineares do limbo foliar

open access: yesAgro@mbiente On-line, 2016
A mensuração da área foliar é requerida em vários estudos agronômicos por ser uma das principais medidas para avaliar o crescimento das plantas. Nesse sentido, objetivou-se com o presente trabalho determinar os modelos estatísticos que melhor descrevem a
