Past, Present and Future Eutrophication Status of the Baltic Sea

Publication Type: Academic Journal

Source(s): Frontiers in Marine Science, Vol 6 (2019)

Abstract: We modelled and assessed the past, present and predicted future eutrophication status of the Baltic Sea. The assessment covers a 350-year period from 1850 to 2200 and is based on: (1) modelled concentrations of dissolved inorganic nitrogen (DIN), disso...

A Review of the Stable Isotope Bio-geochemistry of the Global Silicon Cycle and Its Associated Trace Elements

Publication Type: Academic Journal

Source(s): Frontiers in Earth Science, Vol 5 (2018)

Abstract: Silicon (Si) is the second most abundant element in the Earth's crust and is an important nutrient in the ocean. The global Si cycle plays a critical role in regulating primary productivity and carbon cycling on the continents and in the oceans. Develo...

Biosilicification Drives a Decline of Dissolved Si in the Oceans through Geologic Time

Publication Type: Academic Journal

Source(s): Frontiers in Marine Science, Vol 4 (2017)

Abstract: Biosilicification has driven variation in the global Si cycle over geologic time. The evolution of different eukaryotic lineages that convert dissolved Si (DSi) into mineralized structures (higher plants, siliceous sponges, radiolarians, and diatoms) h...

Assessing the Potential of Sponges (Porifera) as Indicators of Ocean Dissolved Si Concentrations

Publication Type: Academic Journal

Source(s): Frontiers in Marine Science, Vol 4 (2017)

Abstract: We explore the distribution of sponges along dissolved silica (dSi) concentration gradients to test whether sponge assemblages are related to dSi and to assess the validity of fossil sponges as a palaeoecological tool for inferring dSi concentrations o...

Competition between Silicifiers and Non-silicifiers in the Past and Present Ocean and Its Evolutionary Impacts

Publication Type: Academic Journal

Source(s): Frontiers in Marine Science, Vol 5 (2018)

Abstract: Competition is a central part of the evolutionary process, and silicification is no exception: between biomineralized and non-biomineralized organisms, between siliceous and non-siliceous biomineralizing organisms, and between different silicifying gro...

Eutrophication-Driven Deoxygenation in the Coastal Ocean

Publication Type: Academic Journal

Source(s): Oceanography, Vol 27, Iss 1, Pp 172-183 (2014)

Abstract: Human activities, especially increased nutrient loads that set in motion a cascading chain of events related to eutrophication, accelerate development of hypoxia (lower oxygen concentration) in many areas of the world's coastal ocean. Climate changes a...

Quantifying Non-Thermal Silicate Weathering Using Ge/Si and Si Isotopes in Rivers Draining the Yellowstone Plateau Volcanic Field, USA.

Publication Type: Academic Journal

Source(s): Geochemistry, Geophysics, Geosystems: G3; Nov2021, Vol. 22 Issue 11, p1-20, 20p

A longitudinal epigenome-wide association study of preeclamptic and normotensive pregnancy

Publication Type: Academic Journal

Source(s): Epigenetics Communications, Vol 3, Iss 1, Pp 1-16 (2023)

Abstract: Abstract Background While preeclampsia (PE) is a leading cause of pregnancy-related morbidity/mortality, its underlying mechanisms are not fully understood. DNA methylation (DNAm) is a dynamic regulator of gene expression that may offer insight into PE...
