Investigation of Mountain Waves in the Mesosphere over the Andes Mountains
… (from about 87 km altitude), located in the Andes, with the purpose of investigating the atmospheric gravity waves generated when low level wind blows over the high mountains (referred to as Mountain Waves). These types of waves are a special case of atmospheric gravity waves, which carry …

Wind regime characterization, and short-term wind speed and power forecasting using multivariable LSTM and NARX networks in the Andes Mountains, Ecuador
En los últimos años, la investigación ha revelado que los diseños hidroeléctricos en Ecuador no han considerado adecuadamente la sensibilidad al cambio climático. Además, las condiciones climáticas determinan las variaciones en la generación de electricidad a partir de esta fuente de energía …

Spatial and non-spatial patterns of genetic diversity in Neotropical bats
… genetic diversity has been found in the Andes mountains and the Amazon Rainforest, yet it is an open question whether bat genetic diversity is also higher in these regions, or even if any abiotic factors are correlated with bat genetic diversity. Additionally, it is not known if any …

Image Classification using Gabor Filters and Machine Learning
… non-tree areas in aerial imagery of the eastern Andes mountains in Peru. Knowledge of this type of information has strong implications in the study of the effect of climate change on the environment and its conservation. Drawing from recent work on human iris pattern identification, we propose a …

A convergence of bodies in the Anthropocene: post-dictatorship memory in Patricio Guzmán’s triptych (2010-2020)
… Desert, the Patagonian waterways, and the Andes mountains). It argues that, when read together, the documentaries lend themselves to an interdisciplinary analysis of how we might remember state violence committed during the dictatorship of Augusto Pinochet in natural landscapes. It develops …

Climate change and disease at the human-wildlife interface
… the United States-Mexico border and in the Andes Mountains of Chile. The overall modeling efforts did, however, reveal a northward distributional shift of the rabies reservoir as a likely response to climate change. Together, studies contained in this thesis provide empirical, retrospective …

Old World Serpents and New World Dragons: The Evolutionary Dynamics of Pythons and Liolaemid Lizards
… centered on the importance of the uplift of the Andes mountains in generating biodiversity. I find that most lineages originated in Andean regions before dispersing into surrounding biomes. Combined with findings that speciation rates are correlated with rising altitudes, I postulate the Andes …

Triassic to Neogene Evolution of the Andean Retroarc: Neuquén Basin, Argentina
The Andes Mountains provide an ideal natural laboratory to analyze the relationship between the tectonic evolution of a subduction margin, retroarc shortening, basin morphology, and volcanic activity. Timing of initial shortening and foreland basin development in Argentina is diachronous along …

Dynamical Processes of Gravity Waves Propagation and Dissipation, and Statistical Characteristics of Their Momentum Flux in the Mesosphere and Lower Thermosphere
… of the Pacific Ocean, and the other above the Andes Mountains. The difference and similarity provide some clues to the effects of wave sources and background flow on the gravity wave climatology and intermittency in the mesopause region.</p> <p>Firstly, the long-term climatology of intrinsic …

The Impacts of Climate and Landscape Change on Catchment Scale Material Transport in High Mountain and Seasonally Cold Regions
… on catchment scale sediment flux in the high Andes Mountains of Argentina and Chile. In this region, high mountain glaciers buffer streamflow during drier times of the year and water sourced from the uplands is critical to serving the needs of millions of people living in downstream …
