Support for a Photoprotective Function of Winter Leaf Reddening in Nitrogen-Deficient Individuals of Lonicera japonica

open access: yesMolecules, 2014
Plants growing in high-light environments during winter often exhibit leaf reddening due to synthesis of anthocyanin pigments, which are thought to alleviate photooxidative stress associated with low-temperature photoinhibition through light attenuation ...

The association of serum choline concentrations with the risk of cancers: a community-based nested case–control study

open access: yesScientific Reports, 2023
Few studies have been designed to investigate the effect of serum choline on the risk of incident cancer. This study aims to explore the association between serum choline and the risk of new-onset cancer.

Exposure to heat waves and drought improves subsequent leaf heat tolerance for five oak species in southern California

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Given the threats of climate change, we investigated the impact of high temperatures separately and in combination with reduced soil water on leaf heat tolerance for five oaks (Fagaceae) with overlapping ranges in southern California, USA: Quercus agrifolia and Q. chrysolepis (evergreen species), Q. douglasii and Q.

Multimodal models for skin cancer classification using clinical freetext and dermatoscopic images

open access: yesCommunications Medicine
Background Skin cancer is one of the most prevalent cancers globally, with early detection critical to ensure reduced mortality risk. To aid early detection, machine learning (ML) skin cancer detection models have been proposed, currently with a focus on

Turning a new leaf: PhenoVision provides leaf phenology data at the global scale

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Plant phenology dictates many aspects of community function and ecosystem dynamics. Yet, global phenology data are still limited, especially in areas lacking monitoring programs. Here we present a new data resource, PhenoVision–Leaf, which extends a computer vision pipeline utilizing iNaturalist digital image vouchers to produce global‐

Herbarium‐based measurements are reliable predictors of fresh plant traits in Neotropical Myrtaceae

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Herbarium specimens are increasingly used to extract morphological traits for ecological and evolutionary studies, yet the effects of tissue desiccation on trait measurements remain poorly understood. Here, we tested two hypotheses: (H1) whether higher tissue water content leads to greater measurement changes after herborization and ...

Environmental drivers on leaf phenology of ironstone outcrops species under seasonal climate

open access: yesAnais da Academia Brasileira de Ciências
Banded iron formations (BIF) have a particular vegetation type and provide a good model system for testing theories related to leaf phenology, due to unique stressful environmental conditions.

Differential Elevational Diversity Between Overstory and Understory in Tropical Forests

open access: yesBiological Diversity, EarlyView.
Tropical forest overstory and understory exhibit contrasting elevational α‐diversity patterns (unimodal vs. bimodal). Community differentiation is driven by species turnover of dominant rather than rare species, highlighting the need for vertically stratified conservation across the full elevational gradient.

Kin discrimination in plants: overview and implications for population and community ecology

open access: yesBiological Reviews, EarlyView.
ABSTRACT Following the discovery of identity discrimination, particularly self and kin discrimination amongst plant competitors, research on interplant interactions has advanced significantly within plant physiology and evolutionary ecology. This review synthesizes current knowledge on how both self and kin discrimination influence plant growth ...
