Incorporation of nitrogen from N2fixation into amino acids of zooplankton
Incorporation nitrogen N2fixation amino acids zooplankton
2014/4/2
Eurytemora affinis(Copepoda) were fed 15N-labeledRhodomonas salina(Cryptophyta) or 15N-labeled Nodularia spumigena(Cyanobacteria) in excess under controlled laboratory conditions. Zooplankton collecte...
Photoprotection mechanisms against ultraviolet radiation in Heterocapsa sp. (Dinophyceae) are influenced by nitrogen availability: Mycosporine-like amino acids vs. xanthophyll cycle
Heterocapsa sp Photoprotection mechanisms
2014/4/16
The photoprotective and acclimation capacity against ultraviolet radiation (UVR) was assessed for the
dinoflagellate Heterocapsa sp. We examined the effect of UVR and N availability on photosynthetic...
Contribution of mycosporine-like amino acids and colored dissolved and particulate matter to sea ice optical properties and ultraviolet attenuation
amino acids colored dissolved
2014/4/16
In the Baltic Sea ice, the spectral absorption coefficients for particulate matter (PM) were about two times
higher at ultraviolet wavelengths than at photosynthetically available radiation (PAR) wav...
Seasonal and ontogenetic changes of mycosporine-like amino acids in planktonic organisms from an alpine lake
Seasonal and ontogenetic changes mycosporine-like amino acids planktonic organisms an alpine lake
2014/5/4
We studied the quantitative and qualitative mycosporine-like amino acid (MAA) composition in phytoplankton and the copepod Cyclops abyssorum tatricus from an alpine lake over a 15-month period. Up to ...
Dietary acquisition of photoprotective compounds (mycosporine-like amino acids, carotenoids) and acclimation to ulraviolet radiation in a freshwater copepod
Dietary acquisition of photoprotective compounds acclimation to ultraviolet radiation freshwater copepod
2014/5/9
We experimentally tested the hypothesis that accumulations of dietary compounds such as carotenoids or UVabsorbing mycosporine-like amino acids (MAAs) protect against natural levels of ultraviolet rad...
The continuity and intensity of ultraviolet irradiation affect the kinetics of biosynthesis, accumulation, and conversion of mycosporine-like amino acids (MAAs) in the coral Stylophora pistillata
continuity and intensity ultraviolet irradiation accumulation conversion mycosporine-like amino acids coral Stylophora pistillata
2014/5/14
Colonies of Stylophora pistillata unexposed to ultraviolet radiation (UVR) in laboratory aquaria contained minimal amounts of mycosporine-like amino acids (MAAs). The concentration of MAAs increased r...
Major shift in bacterioplankton utilization of enantiomeric amino acids between surface waters and the ocean's interior
Major shift in bacterioplankton utilization of enantiomeric amino acids between surface waters and the ocean's interior
2014/5/20
The peptidoglycan layer of the bacterioplankton cell wall contains four major amino acids (alanine, Ala; serine, Ser; aspartic acid, Asp; and glutamic acid, Glu) in a characteristic enantiomeric ratio...
Preservation of amino acids from in situ–produced bacterial cell wall peptidoglycans in northeastern Atlantic continental margin sediments
amino acids from in situ bacterial cell wall peptidoglycan northeastern Atlantic continental margin sediments
2014/5/26
In this study we present the results of total hydrolysable amino acids (THAA) and amino acid D/L-enantiomers in northeastern Atlantic continental margin sediments. There is increasing evidence that in...

Large variability in the concentration mycosporine-like amino acids located across an altitude gradient
2014/6/9
The qualitative and quantitative composition of mycosporine-like amino acids (MAAs), a family of intracellular UV-absorbing compounds, were investigated in zooplankton from 15 lakes located in the Cen...
