Relationships between synoptic-scale transport and interannual variability of inorganic cations in surface snow at Summit, Greenland: 1992-1996 [PDF]
, 2001 To fully utilize the long-term chemical records retrieved from central Greenland ice cores, specific relationships between atmospheric circulation and the variability of chemical species in the records need to be better understood. This research examines

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security
Journal of the Science of Food and Agriculture, EarlyView.Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

Soil nitrogen fluxes and root uptake in the boreal forest [PDF]
, 2015 Nitrogen (N) is essential for growth and net primary production of plants. However, N acquisition by plants is influenced by movement of soil N compounds from bulk soil to plant roots and uptake of N by roots.

Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND The almond industry requires new strategies to improve almond kernel quality. The use of biostimulants such as potassium silicate (KSi) is an eco‐friendly and non‐polluting alternative. The aim of this work was to investigate the preharvest application of KSi solutions at 2 and 20 mmol L−1 to ‘Peraleja’ almond trees during two ...

EU Peatlands: Current Carbon Stocks and Trace Gas Fluxes [PDF]
, 2004 Peatlands in Europe has formed a significant sink for atmospheric CO2 since the last glacial maximum. Currently they are estimated to hold ca. 42 Gt carbon in the form of peat and are therefore a considerable component in the European carbon budget.

Predicting potential Arctic kelp distribution and lower‐depth biomass from seafloor irradiance
Limnology and Oceanography: Methods, EarlyView.Abstract Kelps have an extensive distribution in Arctic coastal waters. However, quantifying their role in the Arctic food web and carbon cycle is challenged by the scarcity of documented geographical distribution, standing stocks and production. Here we present a framework based on an empirical function to predict the potential kelp distribution and ...

The IceShark, an effective method for sampling plankton under sea ice
Limnology and Oceanography: Methods, EarlyView.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.
