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

open access: yesFunctional Ecology, EarlyView.
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 ...

Preservation of stable isotope niche dynamics in squamate museum specimens

open access: yesJournal of Animal Ecology, EarlyView.
This paper presents the first research on the effects of fluid specimen preservation in a community context, demonstrating the recovery of metrics of niche dynamics across a diverse array of squamate taxa. Abstract Natural history museums are invaluable resources for large‐scale ecological and evolutionary studies, but certain ecological traits can be ...

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

A global estimator of C and N isotope baselines for fresh waters

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Baselines are the pebbles in the shoes of isotope ecologists. The extreme variability of the isotope composition of resources at the base of food webs governs the spatial differences of consumers' isotope composition, so that isotope‐inferred trophic properties can be compared across ecosystems only after correction for baseline effects ...

Fats, Fire and Bronze Age Funerary Rites: Organic Residue Analysis of Wide Horizontal Rim Vessels From Burial Contexts in Northwest Portugal

open access: yesArchaeometry, EarlyView.
ABSTRACT This study presents the first GC‐MS–based analyses of wide horizontal rim vessels with well‐defined funerary contexts, from Middle Bronze Age Portugal (Quinta do Amorim 2 and Pego). Organic residues from two vessels revealed ruminant fats and plant oils, alongside molecular markers of heat exposure.

Fecal Steroids as Tracers of Human Population and Waste Management Practices at the Ancient Maya City of Ucanal, Guatemala

open access: yesArchaeometry, EarlyView.
ABSTRACT Geochemical data compiled from dried sediments from three water reservoirs at the ancient Maya city of Ucanal, Petén, Guatemala, reveal low to undetectable fecal biomarker concentrations. These low concentrations may be the result of the aerobic decay of sterols combined with well‐managed waste disposal practices.

The return of metabolism: biochemistry and physiology of glycolysis

open access: yesBiological Reviews, EarlyView.
ABSTRACT Glycolysis is a fundamental metabolic pathway central to the bioenergetics and physiology of virtually all living organisms. In this comprehensive review, we explore the intricate biochemical principles and evolutionary origins of glycolytic pathways, from the classical Embden–Meyerhof–Parnas (EMP) pathway in humans to various prokaryotic and ...

Clinical Applications of Phosphoproteomics: Illuminating Cancer Signaling and Enabling Rational Therapeutic Strategies

open access: yesCancer Science, EarlyView.
Mass spectrometry‐based phosphoproteomics for mechanistic dissection of cancer signaling pathways and uncovering therapeutic vulnerabilities. ABSTRACT Protein phosphorylation is a central post‐translational modification regulating cellular signaling, frequently dysregulated in cancer.
