Satellite hindcasts of foliar traits reveal a subtle but consistent relaxation of conservativeness in a biodiverse mountain grassland over the last four decades

open access: yesEcography, EarlyView.
Projected warming and drying raise concerns about the resilience of stress‐adapted ecosystems, including the Brazilian Campo Rupestre, an exceptionally biodiverse mountaintop grassland mosaic on ancient, nutrient‐poor substrates. Here, we combine field‐based trait data and long‐term remote sensing to assess the functional structure and temporal ...

Vegetation on the move: elevational shifts and greening dynamics across the Himalayan alpine zone

open access: yesEcography, EarlyView.
This study investigates alpine ‘vegetation line' (the upper limit of continuous plant community) dynamics in the Himalayan alpine zone (HAZ) over a 24‐year timescale (1999–2022) using maximum NDVI products derived from Landsat series datasets, adjusted for sampling bias using phenological modelling.

Exercise‐specific plasma proteomic signatures in racehorses: Candidates for training adaptation and peak load monitoring

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Racehorses undergo profound physiological changes with training and competition, but current biomarkers inadequately capture the complex molecular dynamics of exercise. This study aimed to identify novel plasma biomarkers of training adaptation and peak load using high‐throughput proteomics.

Intraoperative Indocyanine Green Fluorescence Enables Primary Tumor Localization and Treatment De‐Escalation in SCCUP: A Case Report

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Unknown primary cancer in the head and neck presents a difficult surgical treatment dilemma. Patients with squamous cell carcinoma of unknown primary (SCCUP) typically present with an enlarging neck mass found on biopsy but with no indication of primary site on diagnostic exams such as flexible laryngoscopy, CT, MRI, and/or PET/CT ...

Head‐to‐head comparison of the diagnostic value of fecal and serum carcinoembryonic antigen for colorectal cancer detection

open access: yesInternational Journal of Cancer, EarlyView.
What's New? The diagnostic value of fecal versus serum carcinoembryonic antigen (CEA) for colorectal cancer detection remains unclear. This study provides a head‐to‐head comparison of serum and fecal CEA using matched samples from two large colorectal cancer screening studies and two fecal sample processing methods.

Evolutionary dynamics on a regular networked structured and unstructured multi‐population

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView., 2023
Abstract In this paper, we study collective decision‐making in a multi‐population framework, where groups of individuals represent whole populations that interact by means of a regular network. Each group consists of a number of players and every player can choose between two options.
