Adaptation to altitude in Heliconius butterflies
… traits, and genomics underlying adaptation to altitude in the Heliconius butterfly genus. Firstly, using a collection of over 3500 wings I discovered that wing morphology varies predictably across elevations, with species and populations in the highlands having rounder wings than those in the …

Human health impacts of high altitude emissions
… surface emissions, and the contribution of high altitude emissions to these issues is rarely examined. In this thesis, potential links are investigated between high altitude emissions and damages or benefits to human health via photochemical effects. Changes in population exposure to fine …

Limb scatter measurements of high altitude cloud distributions
… lower stratosphere. Cirrus clouds occur at high altitude around the tropopause level and, despite their thin appearance and low optical thickness, they contribute to the radiative balance of the atmosphere. The processes in this region of the atmosphere have become increasingly important for a …

Landscape genomics of tropical high altitude plant species
Changes to species distributions involve demographic processes that occur over generations and affect allele frequencies within populations, leading to patterns of genetic restructuring. The specific genetic structuring patterns that will be observed as a consequence depend on explicit geographical …

Aircraft cruise phase altitude optimization considering contrail avoidance
… of wind-optimal flight at optimal cruise altitude. In comparison, a complementary lateral optimization method reduced 13.3% from the same baseline. Furthermore, flight level optimization shows to be more fuel efficient by reducing the climate impact of contrails by as much as 94% from the …

Adaptive lung growth following exposure to simulated high altitude
Altered oxygen balance in the body at high altitude and in some physiological and pathological conditions may induce adaptive changes in the body which may be organ specific. Because gas exchange is the primary function of the lungs, they may undergo structural changes to adapt to the imbalance of …

Dietary Effects on Pulmonary Function at 3780 Meters Altitude
<p>Diet is known to affect acclimatization to altitude through the effect of carbohydrate on the respiratory exchange ratio. During the first three days following ascent to high altitude, spirometric indices including the forced vital capacity (FVC) and forced expiratory volume in one second (FEVp) …

Model-agnostic Methodology for High-Altitude Balloon Mission Planning
High-altitude balloons (HABs) are increasingly used for atmospheric science, technology validation, Earth observation, and resilient communications. There is a need for modeling HABs in multi-domain missions, and a key challenge for incorporating them is their flight trajectory dependence on …
