Climate impacts on the glaciers and wildlife of the Southern Patagonian Icefield, Chile
The primary goals of this project are to identify the dominant mechanism of tide-water glacier acceleration in the SPI, specifically Témpano and Bernardo Fjords (Figure 1), and to establish a working relationship with both local Chilean government (CONAF) and international (Round River Conservation Studies) organizations to continue this research theme into the future. This partnership will provide resources and logistical support as well as the opportunity to share equipment and data in the greater effort of understanding and conserving the SPI. In addition, we will have the opportunity to not only publish our findings in journals but also to share these findings with local communities and students (ages 8-21) through field trips, classroom visits and citizen-science efforts around the SPI. It is our hope that this interdisciplinary approach will help to inform and involve these communities to continue conservation and protection of national parks in Chile and build upon our research efforts in a collaborative nature.

Future of Periglacial Landscapes: Alpine Ecosystems and Deglaciation in the Tropical Andes and French Alps
First, this research permits to understand the future of proglacial landscapes at a local scale to enhance decision-making and land use management, generating scientific reports for municipalities, regional or national governments. Second, this proposal aims to develop applied solutions to respond to actual and future problems in mountain regions. Our grazing experiment in Peru tests a local solution that can be implemented at a larger scale and in other mountain systems to respond to regional problems. Third, our results from both continents will advance complementary studies worldwide in such regions as the Central and Southern Andes, the Arctic and Scandinavian Mountains, the Himalayan region, and Africa.
In addition, this research provides the groundwork to create awareness and promote international policies for the conservation of deglaciated landscapes. We aim to influence the broader community of international organizations that work on conservation (such as the IUCN, UNESCO, Mountain Research Initiative, ICIMOD, The Nature Conservancy, among others) in a call for the protection and restoration of proglacial landscapes. Up until now, there is no specific effort on this.

The effect of rock climbing on Mediterranean cliff vegetation: Implementation of an innovative and comprehensive methodology in a wide geographical range
This project proposed to evaluate the effects of rock climbing on plant biodiversity in different locations with Mediterranean environmental conditions, one of the most widely distributed biomes around the world, including California, central Chile, Western Cape (South Africa), south of Australia, and the Mediterranean Basin. We conducted field-samplings in different regions along Spain, south of France, and California. This project provides a starting point for the study of the long-term effects of rock climbing on plant communities, and it was a first step for evaluate, for the first time, the effects of rock climbing in a wide geographic range.

Reproductive consequences of climate change-driven alterations in co-flowering between two subalpine plant species
In the summer of 2018, Faust conducted a short-term field experiment to investigate the effects of climate-driven shifts in co-flowering between Linum lewisii and Potentilla pulcherrima. She hoped to answer these questions: Do climate-driven changes in co-flowering between Linum and Potentilla affect fruit and seed set in Linum? Do climate-driven changes in co-flowering affect interspecific competition for pollinator services between Linum and Potentilla? Read her report and find her answers here.

Histories of Arctic climate and environmental contaminants from a shallow ice core, Mt. Oxford, Ellesmere Island
This project involved the drilling of a new ice core on the plateau of Mt. Oxford, a peak on northern Ellesmere Island, to investigate Arctic Ocean sea-ice variability as well as climate and pollutant histories in this region of the Arctic. The records from this new ice core will be compared to records from other ice cores to offer new insights into the spatial variations in accumulation, moisture source, contamination, and marine aerosol deposition across the eastern Canadian high Arctic.

The Clark's Nutcracker Project: Engaging young adventurers in citizen science.
The whitebark pine is a high-elevation tree entirely dependent upon the Clark's nutcracker to disperse its seeds, and this tree species has suffered greatly from an invasive fungus and a native bark beetle. This research utilized the observation powers of young adventurers to collect data on whitebark pine and Clark's nutcrackers during wilderness expeditions across four remote mountain ranges in Wyoming and Montana.

The importance of within-patch heterogeneity for population dynamics of a high elevation pine.
With mountainous regions across the globe being strongly affected by climate change, it is important to develop reliable models for characterizing how mountain species are affected by environmental variation. This research used new and existing data for whitebark pine in the Elkhorn Mountains of Oregon to test whether within-population variation, such as elevation gradients, can change predictions for the persistence of this species.

Wilderness Rock Climbing Indicators and Climbing Management Implications in the National Park Service
What makes climbing in wilderness unique? How can climbing management practices honor local values and uphold wilderness ideals? McHugh’s study addresses the need to characterize the wilderness climbing resource in National Parks so that it may be appropriately monitored and managed. Deliverables of the research include, first; a critical review of literature, law, policy, and agency practices, and second; the development of tools to describe and define the wilderness climbing resource and a monitoring protocol to document change over time. Research is in-progress; a final report will be posted upon completion.

Biogeography of Snow Algae Communities in the Pacific Northwest
The pink or "watermelon" snow seen occasionally in alpine environments is indicative of the presence of snow algae, one of the many species inhabiting biodiverse alpine ecosystems. The algae's pigmentation increases snow melting, making research into the snow algae populations critical to climate change models. This researcher collected samples from Oregon and Washington for molecular analysis to better understand variability across snow algae communities in the Pacific Northwest. Read more here.

Assessing Risk of Glacial Outburst Flooding from the Imja Lake, Nepal
Located southeast of Mt. Everest, The Imja Lake is dammed by the terminal moraine of the Imja Glacier. As melt water from the glacier causes the Imja Lake to grow, the risk of catastrophic flooding to the down-stream communities grows. This study measured glacial dimensions, glacial retreat and lake depth over several years to model future glacial dynamics and the risk of outburst flooding. Read more here.

Surveying Adaptation and Recovery in Mountain Farming Communities in Nepal After the 2015 Earthquakes
Nepal is still recuperating from the series of earthquakes that occurred early in 2015. In this study, households in farming communities in the mountainous district of Dolakha are interviewed and surveyed. Results indicate that subsistence agricultural systems were heavily impacted in the earthquakes and that household perceptions of recovery are highly differentiated, despite largely uniform and widespread damages across study sites.
