High Altitude Illness [PDF]

Journal of the Royal Army Medical Corps, 2005
Introduction The aims of this article are to outline the physiology of high altitude, the treatment of altitude illness and to describe opportunities for further education in mountain medicine. Human difficulty with the rarefied air at high altitudes has been recognised since ancient times.

Evaluating patterns of plant phenological progression and pronghorn movement behaviors across diverse landscapes Évaluation des modèles de progression phénologique des plantes et des comportements de mouvement des antilopes d'Amérique dans divers paysages

Wildlife Monographs, Volume 218, Issue 1, September 2025.
We found variable spatial and temporal patterns and predictability of plant phenological progression across 8 pronghorn ranges in Montana. We sampled potential exposure to phenology values for migrants and residents along spring movement paths and summer ranges and found that within herds and years the resident and migrant movement strategies conferred

Wood density variation across an Andes‐to‐Amazon elevational gradient

Journal of Ecology, Volume 113, Issue 9, Page 2370-2385, September 2025.
We study how wood density varies along a 3500‐m elevational gradient, spanning from the Andean tree line to the Amazon basin. Our results reveal that wood density decreases from low to mid‐elevations, then increases toward the tree line. These patterns underscore the influence of species composition, life forms such as tree ferns, and local ...

The duration of high spring light for understorey plants: Contrasting responses to spatial and temporal temperature variation

Journal of Ecology, Volume 113, Issue 9, Page 2526-2538, September 2025.
Over 7 years, warmer springs were associated with earlier leaf‐out of two temperate forest understorey herbs and of the trees above them, but the effect was stronger for the herbs. This suggests that climate warming will prolong the relatively brief period of high light available to understorey plants in spring, which is a key determinant of their ...

Efecto de la temperatura de la Rizosfera sobre la distribución de la materia seca en uchuva (Physalis peruviana L.) Effect of rizosphere temperature on the dry matter distribution in cape gooseberry (Physalis peruviana L.)

Agronomía Colombiana, 1998
En el hábitat natural de la uchuva en Colombia (de 1.600 a 2.800 msnm) la temperatura edáfica varía de acuerdo con los<br />factores climatológicos determinados por la altitud y por el manejo que se le de al suelo y al cultivo.

Mammal Species Composition and Activity Patterns Shift While Richness Remains Constant Across Elevational Gradients in Western Sarawak, Borneo

Biotropica, Volume 57, Issue 5, September 2025.
We examined how mid‐ to large‐bodied mammal communities vary along elevational gradients in northwestern Borneo using camera trap data from six protected areas. Although species richness remained constant across elevations, species composition and activity patterns shifted, with some taxa more common at low or high elevations. These findings underscore
