Enrichment of particulate phosphorus in a sea-surface microlayer over the Eastern Equatorial Pacific Ocean
sea-surface microlayer biogeochemical enrichment particulate phosphorus high-nutrient low-chlorophyll ocean
2017/4/11
The significant enrichment of chemical composition associated with enhanced bioactivities and an increased number
of bio-particles in the sea-surface microlayer (SML) were observed in the high-nutrie...
Roles of phosphorus and ultraviolet radiation in the strength of phytoplankton–zooplankton coupling in a Mediterranean high mountain lake
Roles of phosphorus ultraviolet radiation
2014/4/17
Ultraviolet solar radiation (UVR) and atmospheric nutrient inputs associated with aerosols are major
worldwide stressors that simultaneously affect species and the interaction among them. A 2 3 5 fie...
Quantifying phosphorus and light effects in stream algae
Quantifying phosphorus light effects stream algae
2014/4/17
Simultaneous gradients of phosphorus and light were applied in experimental streams to develop quantitative
relationships between these two important abiotic variables and the growth and composition ...
Phosphorus release with carbonate dissolution coupled to sulfide oxidation in Florida Bay seagrass sediments
Phosphorus release carbonate dissolution
2014/4/17
We hypothesized that CaCO3 dissolution, coupled to sulfide oxidation, is an important mechanism by which
solid-phase inorganic P (iP) becomes available to seagrass in tropical carbonate sediments. To...
Differential effects of phosphorus limitation on cellular metals in Chlorella and Microcystis
phosphorus limitation Chlorella Microcystis
2014/4/21
We investigated the effect of phosphate bioavailability on cellular metal quotas in two species of freshwater
phytoplankton (the eukaryote Chlorella sp. UTCC522 and the cyanobacterium Microcystis sp....
Molecular assessment of phosphorus and iron physiology in Trichodesmium populations from the western Central and western South Atlantic
Molecular assessment phosphorus iron physiology
2014/4/22
Trichodesmium is capable of responding to low phosphorus (P) and low iron (Fe) concentrations through the
induction of alkaline phosphatase (AP) activity (an enzyme that hydrolyzes inorganic phosphat...
Historic low-level phosphorus enrichment in the Great Lakes inferred from biogenic silica accumulation in sediments
Historic low-level phosphorus enrichment Great Lakes inferred
2014/4/30
Sedimentary biogenic silica (BSi) accumulation was used in conjunction with a hypothetical model of BSi
accumulation to show that BSi is a sensitive proxy for low-level phosphorus enrichment in the G...
Is phosphorus retention in autochthonous lake sediments controlled by oxygen or phosphorus?
autochthonous lake sediments phosphorus retention
2014/4/30
Eutrophication of various lakes on the Swiss Plateau was targeted in the 1980s by reducing external nutrient
loading and installing aeration/oxygenation systems. For five eutrophic lakes, three...
The stoichiometry of dissolved organic carbon, nitrogen, and phosphorus release by a planktonic grazer, Daphnia
dissolved organic carbon nitrogen phosphorus release
2014/5/19
We examined the relationship between Daphnia release rates and ratios of dissolved organic carbon (DOC),
nitrogen (N), and phosphorus (P) and the elemental composition of algal food. We constructed a...
Nutrient budget for the Eastern Mediterranean: Implications for phosphorus limitation
he Eastern Mediterranean phosphorus limitation
2014/5/19
The eastern Mediterranean has a high nitrate to phosphate (N : P) ratio (;28 : 1) in the deep water and a highly
unusual P limitation of the primary productivity. We present a detailed nutrient budge...
Phosphonates and particulate organic phosphorus cycling in an anoxic marine basin
Phosphonates particulate organic phosphorus
2014/5/19
The phylogenetic composition of bacterial communities varies along the salinity gradient of estuaries, one notable
pattern being the prevalence of alpha- and beta-proteobacteria in salt- and freshwat...
Atmospheric deposition of inorganic phosphorus in the Levantine Basin, eastern Mediterranean: Spatial and temporal variability and its role in seawater productivity
Levantine Basin eastern Mediterranean
2014/5/21
Total and dissolved inorganic phosphorus (IP) was measured in both rainwater and aerosol samples collected
from two remote coastal areas: on the island of Crete (Greece) and at Erdemli (Turkey). Part...
Effects of dietary phosphorus deficiency on the abundance, phosphorus balance, and growth of Daphnia cucullata in three hypereutrophic Dutch lakes
dietary phosphorus defi ciency abundance phosphorus balance
2014/5/30
We studied population dynamics, phosphorus balance, and individual growth to evaluate limitation of Daphnia
cucullata by dietary phosphorus (P) in three interconnected, hypereutrophic Dutch lakes. Co...
