Ecological homogenization of soil properties in the American residential macrosystem

Ecosphere, 2022
The conversion of native ecosystems to residential ecosystems dominated by lawns has been a prevailing land‐use change in the United States over the past 70 years.

Combining the Underwater Vision Profiler 6 with sediment traps to measure in situ velocity of marine particles

Limnology and Oceanography: Methods, EarlyView.
Abstract Particles sinking from the surface to the deep ocean play a key role in the biological carbon pump, whose efficiency depends partly on sinking velocities. Over the last decade, in situ imaging has enabled critical advances in our understanding of particle dynamics in the ocean.

The Differential Responses of Coastal Diatoms to Ocean Acidification and Warming: A Comparison Between Thalassiosira sp. and Nitzschia closterium f.minutissima

Frontiers in Microbiology, 2022
Marine diatoms are one of the marine phytoplankton functional groups, with high species diversity, playing important roles in the marine food web and carbon sequestration.

Dissolved organic carbon uptake in streams: A review and assessment of reach‐scale measurements [PDF]

, 2016
Quantifying the role that freshwater ecosystems play in the global carbon cycle requires accurate measurement and scaling of dissolved organic carbon (DOC) removal in river networks.

Microbially driven organic carbon cycling at the land−sea interface: Advances and an integrated study framework

mLife, EarlyView.
Abstract The land−sea interface is a vital component of global biogeochemical cycles, where microorganisms drive the cycling of carbon, nitrogen, and sulfur. This review synthesizes the research progress from representative land−sea interfaces to elucidate how the microbial community structure and metabolic function influence the mobilization ...

Metabolic Network Analysis Reveals Human Impact on Urban Nitrogen Cycles

Land
Human interactions have led to the emergence of a higher complexity of urban metabolic networks; hence, traditional natural- or agriculture-oriented biogeochemical models might not be transferred well to urban environments.

Co- variation in soil biodiversity and biogeochemistry in northern and southern Victoria Land, Antarctica [PDF]

, 2006
Data from six sites in Victoria Land (72–77°S) investigating co-variation in soil communities (microbial and invertebrate) with biogeochemical properties showthe influence of soil properties on habitat suitability varied among local landscapes as well as

Impacts of reindeer grazing on phosphorus sorption and nutrient availability in a tundra site

Oikos, EarlyView.
Reindeer Rangifer tarandus, a large circumpolar herbivore, can influence whether nitrogen (N) or phosphorus (P) is the primary limiting nutrient in tundra plant communities. Specifically, findings from a site in northern Scandinavia suggest that under conditions where reindeer grazing stimulates inorganic N availability, grazing may drive ecosystems ...

Continental scale variability in ecosystem processes: Models, data, and the role of disturbance [PDF]

, 1997
Management of ecosystems at large regional or continental scales and determination of the vulnerability of ecosystems to large-scale changes in climate or atmospheric chemistry require understanding how ecosystem processes are governed at large spatial ...
