Artificial rainfall patterns alter non‐structural carbohydrate allocation to modulate growth and eco‐stoichiometry in Cyphomandra betacea seedlings

Plant Biology, Volume 28, Issue 2, Page 487-497, March 2026.
Changes in rainfall patterns severely affect plant growth. Cyphomandra betacea seedlings adapt to such changes by adjusting inter‐organ biomass allocation, dynamically regulating stoichiometric characteristics, and non‐structural carbohydrate allocation.

Ribcage Morphology in Native South American Populations From Different Altitudes: Insights From a Global Comparative Framework

American Journal of Human Biology, Volume 38, Issue 2, February 2026.
ABSTRACT Objectives Altitude shapes human morphology as highland populations must cope with cold and hypoxic environments. Although Andean highlanders have been proposed to exhibit larger and deeper ribcages, this idea is mainly based on research using disarticulated skeletal elements or non‐South American controls. The objective of this research is to

The Impact of High‐Intensity Exercise in Normobaric Hypoxia on Right Ventricular Function in Trained and Untrained Men—An Echocardiographic Study

Comprehensive Physiology, Volume 16, Issue 1, February 2026.
A single bout of high‐intensity exercise to volitional exhaustion under acute normobaric hypoxia (~3000 m a.s.l.; FiO2 = 14.4%) does not induce greater alterations in right ventricular systolic function compared to normoxia in either trained or untrained healthy men.

The Genetic and Morphological Basis of Local Adaptation to Elevational Extremes in an Alpine Finch

Ecology and Evolution, Volume 16, Issue 2, February 2026.
We investigated morphological and genetic variation in the Sierra Nevada Gray‐crowned Rosy Finch to identify traits important for local adaptation in alpine environments. By combining trait measurements with genome‐wide analyses, we uncovered loci linked to thermoregulation, altitude adaptation, and cold tolerance.
