The Science Issue and Relevance: Coastal wetlands are some of the most productive and valuable habitats in the world. Louisiana contains 40% of the United States’ coastal wetlands, which provide critical habitat for waterfowl and fisheries, as well as many other benefits, such as storm surge protection for coastal communities. In terms of ecosystem services, biological resource production, and infrastructure investments, the value of Louisiana’s coastal wetlands exceeds $100 billion. Thus, stakeholders are gravely concerned about sea-level rise which is causing coastal marsh habitat to convert to open water and resulting in the highest rates of wetland loss in the world, with nearly 1.2 million acres lost since...

Recently intensifying drought conditions have caused increased stress to non-native tamarisk vegetation across riparian areas of the San Carlos Apache Tribe (hereafter Tribe) and the Upper Gila River watershed in Arizona and New Mexico. This also increases wildfire risk in the area, making the removal of tamarisk vegetation a primary restoration and climate adaptation objective for the Tribe. The research from this project can improve the Tribe’s capacity to map tamarisk and other riparian vegetation, in addition to monitoring the relative condition and water stress of the vegetation in a timely manner. Specifically, the project will help identify where tamarisk is on the reservation and inform restoration actions...

Many amphibian species are highly susceptible to changes in precipitation timing and volume because of their reliance on intermittently flooded surface water pools, which are primarily filled through snowmelt and precipitation runoff. ​With increasing evapotranspiration (i.e. transfer of water from land to the atmosphere) due to climate change, the timing and availability of water in key amphibian reproductive habitats will likely be altered. This project will assess the future risk to amphibian populations in the Midwest, identifying present and future richness hotspots and those wetland species and populations most at risk of habitat loss due to climate change. The research team will model landscape level changes...

Salmon runs are an important time when salmon migrate from the ocean to freshwater, swimming upriver to reach spawning beds. These annual events provide an important food source for both predators and for local communities. However, Recent declines in salmon runs have caused hardship in subsistence fishing communities throughout Alaska, particularly in the Yukon River Basin. To adapt to a changing climate, fishing communities, natural resource managers, and scientists need to measure and understand climate impacts onto salmon runs in this region. To monitor changes in salmon populations and manage fisheries, the Alaska Department of Fish and Game (ADFG), U.S. Fish and Wildlife Service (USFWS), and Tanana Chiefs...

California black oak (Quercus kelloggii) groves are a fundamental part of the landscape in Yosemite Valley and the tree is a cultural keystone species for associated Tribal Nations. For centuries, tribal members have planted, tended, burned, and gathered around black oak. Before Euro-American settlers, the tribes actively maintained a sacred, reciprocal relationship with these groves that promoted seedling recruitment, acorn production, pest reduction, and longevity. After Park creation, cultural practices were largely prohibited to the detriment of black oak and tribal health. This project will reinstate tribal members as stewards of black oak through tending and knowledge transmission. Tribal members, with...

Indirect interactions between different prey species modulated by shared predators (e.g. Arctic fox) are believed to have important impacts on the structure and/or dynamics of some communities. Yet, our understanding of these types of interactions are still fragmentary. To fill this information gap, the joint circumpolar project on indirect trophic interactions was established in 2016. This project built upon ongoing projects exploring related questions in Canada (Marie-Andrée Giroux, Nicolas Lecomte, Joel Bety) and Greenland (Olivier Gilg, Niels M. Schmidt), while taking advantage of existing networks (ASDN in North America and “Interactions” program in Greenland and Eurasia). The aim of this project was to promote...

In 2020, Governor Edwards of Louisiana issued two executive orders: establishing the Climate Initiatives Task Force to develop the state’s first ever Climate Action Plan to reach net zero greenhouse gas emissions by 2050 and to enhance coastal resilience in the state. Louisiana’s coastal wetlands and natural lands are of vital importance not just for hurricane protection, health and wellbeing, and natural resources, but also for carbon sequestration (i.e. capturing and storage of carbon from the atmosphere). Enhancing natural carbon sinks (i.e. ecosystem that stores more carbon than it releases) to offset greenhouse gas emissions is a critical step for Louisiana to achieve its net zero goals. Coastal wetlands have...
