On the Limits of Alpine Plants: A Systematic Review of the Factors Behind Species' Elevational Range Limits [PDF]
Ecology and Evolution, Volume 16, Issue 3, March 2026.This systematic review of 107 studies on the factors behind the elevational range limits of alpine vascular plants shows a persistent emphasis on upper limits and abiotic factors, especially temperature, while work at lower limits is more evenly distributed across water availability, plant–plant interactions, and selection/local adaptation.

Altitude sickness and altitude adaptation [PDF]
Acta Physiologica, 2017 For as long as humanity can recall, it has probably been a dream of mankind to conquer mountainous heights and the mysterious deep. Loss of innocence is a common theme across ancient religions. Ancient Hindu legend has an interesting variation on the story: When Brahma realized that man did not deserve divinity, he decided to take it from them and hide

The American Mathematical Monthly, 2023 A long-standing, unanswered question regarding Euclid's Elements concerns the absence of a theorem for the concurrence of the altitudes of a triangle, and the possible reasons for this omission. In the centuries following Euclid, a remarkable number of proofs have been put forward; this suggests a search for the most elementary and direct proof.
