Study reveals changing patterns in globally important algae（图）
changing patterns globally algae
2019/10/21
Globally important ocean algae called coccolithophores are mysteriously scarce in one of the most productive regions of the Atlantic Ocean, according to a new paper in Deep Sea Research I. A massive d...
Study uncovers surprising melting patterns beneath Antarctica's Ross Ice Shelf（图）

Scientists working on the ROSETTA-Ice project, a three-year, multi-institution survey of the Ross Ice Shelf in Antarctica, have assembled an unprecedented view of the seafloor beneath the ice sheet.In...
Patterns and Controls of Nutrient Concentrations in a Southeastern United States Tidal Creek
Nutrient Concentrations Southeastern United States
2015/7/16
Terrestrial inputs largely govern nutrient delivery to the coastal ocean, and subsequent processes transform these nutrients in the land-ocean transition zone. Here, we describe spatial and temporal p...
Spatiotemporal distribution and activity patterns of bacteria from three phylogenetic groups in an oligomesotrophic lake
Spatiotemporal distribution an oligomesotrophic lake
2014/4/16
We explored the seasonal and vertical patterns of cell numbers, biomass, and amino acid incorporation of three
major phylogenetic groups of the bacterioplankton in an oligomesotrophic alpine lake. Th...
Assimilatory uptake rather than nitrification and denitrification determines nitrogen removal patterns in streams of varying land use
Assimilatory uptake nitrification denitrification deter nitrogen removal patterns in streams of varying land use
2014/4/18
Agricultural and urban land use increase nitrogen (N) concentrations in streams, which can saturate biotic demand by plants, algae, and bacteria via assimilative uptake, and by nitrification and denit...
Patterns and regulation of dissolved organic carbon: An analysis of 7,500 widely distributed lakes
Patterns regulation dissolved organic carbon 7,500 widely distributed lakes
2014/4/22
Dissolved organic carbon (DOC) is a key parameter in lakes that can affect numerous features, including microbial metabolism, light climate, acidity, and primary production. In an attempt to understan...
Investigating the use of macrophyte stable C and N isotopic ratios as indicators of wetland eutrophication: Patterns in the P-affected Everglades
macrophyte stable C N isotopic ratios wetland eutrophication Patterns in the P-affected Everglades
2014/5/5
We investigated the use of stable C and N isotopic ratios as indicators of shifts in nutrient limitation of aquatic macrophytes in native Typha (Typha domingensis Pers.) and Cladium (Cladium jamaicens...
Periphyton responses to eutrophication in the Florida Everglades: Cross-system patterns of structural and compositional change
Periphyton Florida Everglades Cross-system patterns
2014/4/30
We examined periphyton along transects in five Everglades marshes and related compositional and functional
aspects to phosphorus (P) gradients caused by enriched inflows. Results were com...
Evolutionary animation: How do molecular phylogenies compare to Mayr’s reconstruction of speciation patterns in the sea?
Evolutionary animation molecular phylogenies
2015/12/16
ernst Mayr used the geography of closely related species in various
stages of increasing divergence to ‘‘animate’’ the process of geographic, or allopatric, speciation. This approach was applied to a...
Spatiotemporal patterns of carbon remineralization and bio-irrigation in sediments of Casco Bay Estuary, Gulf of Maine
Spatiotemporal patterns carbon mineralization bio-irrigation in sediments Casco Bay Estuary Gulf of Maine
2014/5/14
We measured the seasonal and spatial rates of organic matter decomposition and pore-water irrigation at four subtidal stations in Casco Bay estuary, Gulf of Maine. Organic carbon decomposition and ass...
Latitudinal patterns in the size distribution and seasonal dynamics of new world, freshwater cladocerans
Latitudinal pattern size distribution seasonal dynamics new world freshwater cladocerans
2014/6/17
Analysis of zooplankton communities in over 1,100 water bodies spanning the Western Hemisphere (77°S, 81°N latitude) revealed latitudinal patterns in cladoceran body size and Daphnia seasonal dynamics...
