Arctic and boreal carbon
This chapter summarizes the current knowledge in high-latitude (mostly permafrost) carbon storage and dynamics. Arctic and boreal regions contain large carbon stock, especially in permafrost soils. The factors that control carbon storage have been changing rapidly over the last several decades. As a result, this large carbon pool is highly vulnerable for carbon loss in a future warming climate.

Hypotheses from recent assessments of climate impacts to biodiversity and ecosystems in the United States
Climate change poses multiple threats to biodiversity, and has already caused demonstrable impacts. We summarize key results from a recent national assessment of observed climate change impacts to terrestrial, marine, and freshwater ecosystems in the United States, and place results in the context of commonly articulated hypotheses about ecosystem response to climate change for global implications

Sediment transport and deposition
Sediment transport and deposition (sedimentation) occurs from natural and anthropogenic sources in rivers, lakes, and reservoirs. Substantial changes in sediment transport (such as a major increase or decrease in sediment supply) can impact aquatic ecosystems that depend on a particular sediment quantity and particle size, for example, through altering stream-channel geomorphology or fish habitat.

Chiroptera
With over 1300 species identified, bats represent almost one quarter of the world’s mammals (Fenton and Simmons 2014), bats provide important environmental services such as insect pest suppression, seed dispersal, and pollination and inhabit a wide variety of ecological niches on all continents except Antarctica. Over 150 species are listed as endangered or vulnerable to extinction, primarily due

Fish Lake limnology and watershed aqueous geochemistry, Fish Lake Plateau, Utah
Fish Lake is located at 2696 m elevation on the Fish Lake Plateau with a bedrock geology of Oligocene to Pliocene age volcanics and Cretaceous to Eocene age sedimentary rocks. Lake bathymetry indicates a maximum depth of ~27 m and volume of 2.31 x 108 m3. The lake is dimictic with summer water column temperature declines of 13˚C between 7 to 15 m depth, whereas in spring and fall water column is i

Floristic quality index and forested floristic quality index: Assessment tools for restoration projects and monitoring sites in coastal Louisiana
The Floristic Quality Index (FQI) has been used in many areas throughout the United State to assess the integrity of plant communities and restoration projects. Here, we summarize two tools that have been developed for monitoring sites in coastal Louisiana wetlands. The FQI was modified for herbaceous data collected in coastal Louisiana monitoring sites. A second FQI, the Forested Floristic Qualit

Geology and geologic history: Overview of the geology of the San Francisco Bay region
The geology of San Francisco and the surrounding northern and central California area has played a pivotal role in the development of our understanding of Earth processes, especially the process of tectonic accretion at a continental margin and the development of transform plate margins. The Franciscan Complex, which underlies most (or perhaps all) of the City and County of San Francisco, is wide

Farmer-managed restoration of agroforestry parklands in Niger
Land rehabilitation enables sustainable intensification of agriculture and more resilient food
production systems. Despite severe development challenges, Niger is the site of successful,
farmer-managed efforts to counteract the global trend in land degradation that was supported
by policy change. The vast majority of Niger’s land is located in the Sahara. Following a series of
severe droughts duri
