Tara OceansPhotosynthesis evolved in the ocean more than 2 billion years ago and is now performed by a wide range of evolutionarily distinct organisms, including both prokaryotes and eukaryotes. Our appreciation of their abundance, distributions, and contributions to primary production in the ocean has...
Trypsin is best known as a digestive enzyme in animals, but remains unexplored in phytoplankton, the major primary producers in the ocean. Here we report the prevalence of trypsin genes in global ocean phytoplankton and significant influences of environm
Global climate change has generated an increasing number of environmental problems, especially in Mediterranean coastal areas, such as the Po Delta (PD), where shellfish production has undergone an overall decline because of strong environmental changes. The present study is centred on assessing the ...
Four major functional units have been identified in the Southern Ocean and the mechanisms that control the dynamics of nutrients and phytoplankton are detailed for the different sub-systems. The very productive Coastal and Continental Shelf Zone (CCSZ, 0
Phytoplankton Synonyms Algae;Microalgae Definition The term plankton comes from the Greek meaning to drift or wander and was introduced in 1887 by Victor Hensen to refer to biological matter that drifts in bodies of water (Mills1989). The term phytoplankton refers to the photosynthetic species of ...
Phytoplankton records in environmental parameter space. The phytoplankton occurrences compiled cover the entire temperature range and a broad part of nitrate and mixed-layer conditions found in the global ocean. 环境覆盖面足够大。 困了qwq快进。Taxonomic coverage也够大,计算了completeness(收集度hhh),还讨...
The proposed dynamic approach toward monitoring nutrient availability can contribute to refined estimates of biogeochemical fluxes in the world ocean. 展开 关键词: aerosols biogeography cell size chlorophyll a iron nitrate DOI: 10.1029/2001GB001640 被引量: 80 ...
We gathered 18S rRNA gene metabarcoding data and complemented it with confocal microscopy images, both from the Tara Oceans expedition in late spring 2010. Our work showed local and regional variation across three different size fractions that reflect the complexity of this regi...
Due to ongoing climate change, which is progressively warming the ocean, we are witnessing more stratified water columns with a decrease in mixing and subsurface nutrient supply to the euphotic layer. It is important to understand the mechanisms of nutrient supply and to identify potential hot spot...
Changes in the environmental condition associated with climatic events could potentially influence the PSC dynamics of the regional marine ecosystem. The Indian Ocean dipole (IOD) is one of the critical ocean–atmosphere interactions that affects the climate of the Arabian Sea, and it could be a po...
