Elevational variation in heart mass and suppression of hypoxia‐induced right ventricle hypertrophy in Andean leaf‐eared mice (Phyllotis)

The Journal of Physiology, EarlyView.
Abstract figure legend In lowland mammals that ascend to high elevation, hypoxia‐induced changes in the pulmonary circulation can give rise to hypoxic pulmonary hypertension (HPH) and associated right‐ventricle (RV) hypertrophy. Andean mice with broad elevational ranges have greater heart mass relative to body size at higher elevations, but they ...

Geomorphic Traces of Quaternary Climates in the Cordillera Central, Dominican Republic

Mountain Research and Development, 1997
The Cordillera Central in the Dominican Republic, island of Hispaniola, exceeds 3,000 m in height. Schubert and Medina (1982) identified possible relict glacial geomorphic features on air photographs. Modern mid-elevation lapse rates of -8.50C km-1 yield plausible paleo-snowlines below peak elevations with sea-surface temperature depressions between 2'

Assessing Wildfire Hazard for Powerline Expansion Under the Changing Climates in Alberta, Canada

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Escaped powerline‐caused fires (EPFs) are increasing in fire‐prone regions, including Alberta, Canada, underscoring growing tensions between expanding powerlines and managing wildfire risk. As fire‐conducive weather becomes more frequent, it remains unclear how future infrastructure can be planned to minimize wildfire risk.

Geochemistry of low‐temperature dolomite formation in coastal and continental saline to sabkha‐like environments

The Depositional Record, Volume 12, Issue 4, September 2026.
This study compares primary dolomite precipitation in modern and ancient environments, varying from coastal to transitional to continental saline environments. The microbially mediated dolomites are characterised by high Sr concentrations. Here, various geochemical proxies are studied and compared to previous findings.
