The IceShark, an effective method for sampling plankton under sea ice
Abstract Seasonal sea ice plays a crucial role in shaping coastal ecosystem dynamics throughout the circumpolar region. Of particular interest to oceanographers is the ice‐ocean interface which functions as a multidimensional habitat, supporting both sympagic algae and pelagic phytoplankton in the under‐ice surface waters.

Environmental Impacts—Freshwater Biogeochemistry [PDF]
Climate change effects on freshwater biogeochemistry and riverine loads of biogenic elements to the Baltic Sea are not straight forward and are difficult to distinguish from other human drivers such as atmospheric deposition, forest and wetland management , eutrophication and hydrological alterations. Eutrophication is by far the most well-known factor

Abstract Accurate quantification of particulate phosphorus is critical for understanding biogeochemical processes in aquatic systems. Extra high‐temperature dry combustion at 800°C improves phosphorus recovery by ~ 11% compared to lower‐temperature methods.

Metabolic Network Analysis Reveals Human Impact on Urban Nitrogen Cycles
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.

Understanding community assembly for wild species in anthropogenic settings has become increasingly important as biodiversity and ecosystem services are threatened by development pressures. Urban hardscape habitats such as parking lots are widespread, extreme, terrestrial anthropogenic environments that influence plant community assembly by way of ...

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

Abstract Different aspects of ecological systems, biotic or abiotic, often fluctuate in coordinated patterns over space and time. Such high concordance between ecological processes is often referred to as ecological synchrony. Human activities, including and beyond climate change, have the potential to alter ecological synchrony by disrupting or ...
