AI Article Synopsis

  • Understanding the concentrations and elemental ratios of suspended particles in the ocean is key to studying biogeochemical processes, including nutrient limitations for phytoplankton and the interactions between carbon and nitrogen or phosphorus cycles.
  • A global dataset has been compiled with 100,605 measurements of particulate organic carbon, nitrogen, and phosphorus from 70 ocean cruises and time-series, covering all major ocean regions and various depths.
  • The global median ratios for carbon to phosphorus (C:P), nitrogen to phosphorus (N:P), and carbon to nitrogen (C:N) are 163, 22, and 6.6, respectively, but there is significant variation based on regional differences, aiming to aid future ocean studies.

Article Abstract

Knowledge of concentrations and elemental ratios of suspended particles are important for understanding many biogeochemical processes in the ocean. These include patterns of phytoplankton nutrient limitation as well as linkages between the cycles of carbon and nitrogen or phosphorus. To further enable studies of ocean biogeochemistry, we here present a global dataset consisting of 100,605 total measurements of particulate organic carbon, nitrogen, or phosphorus analyzed as part of 70 cruises or time-series. The data are globally distributed and represent all major ocean regions as well as different depths in the water column. The global median C:P, N:P, and C:N ratios are 163, 22, and 6.6, respectively, but the data also includes extensive variation between samples from different regions. Thus, this compilation will hopefully assist in a wide range of future studies of ocean elemental ratios.

The primary production of fjords across the Arctic and Subarctic is undergoing significant transformations due to the climatically driven retreat of glaciers and ice sheets. However, the implications of these changes for upper trophic levels remain largely unknown. In this study, we employ both bulk and compound-specific stable isotope analyses to investigate how shifts at the base of fjord food webs impact the carbon and energy sources of consumers.

Background And Aims: Understanding interspecific differences in plant growth rates and their internal and external drivers is key to predicting species responses to ongoing environmental changes. Annual growth rates vary among plants based on their ecological preferences, growth forms, ecophysiological adaptations, and evolutionary history. However, the relative importance of these factors remains unclear, particularly in high-mountain ecosystems experiencing rapid changes.

Herein, the construction of potential donor-acceptor (D-A) structures was guided using density-functional theory (DFT) calculations. The photocatalytic nitrogen fixation performance of TAPT-CHF was then experimentally determined to be 327.58 μmol g h, which was attributed to its efficient photo-induced charge separation and migration ability.

Insect farming: A bioeconomy-based opportunity to revalorize plastic wastes.

Managing plastic waste is one of the greatest challenges humanity faces in the coming years. Current strategies-landfilling, incineration, and recycling-remain insufficient or pose significant environmental concerns, failing to address the growing volume of plastic residues discharged into the environment. Recently, increasing attention has focused on the potential of certain insect larvae species to chew, consume, and partially biodegrade synthetic polymers such as polystyrene and polyethylene, offering novel biotechnological opportunities for plastic waste management.

Forage crop rotations including grasslands, common in dairy systems, are known to ensure good productivity and limit the decrease of soil organic matter frequently observed in permanent arable land. A dataset was built to compile data from the Kerbernez long-term experiment, conducted in Brittany(France) from 1978 to 2005. This experiment compared the effect of different forage crop rotations fertilized with ammonium nitrate and/or slurry, with or without grassland, on forage production (quantity, quality) and changes in soil physio-chemical characteristics.
