Data from: Expressions of nitrate transporter genes reveal different nitrogen statuses of dominant diatom groups in the southern East China Sea
In this study, the mRNA levels of the Nrt2 nitrate transporter gene were used as a molecular indicator of nitrogen status in two dominant diatom groups, Skeletonema and Chaetoceros, which inhabit the southern East China Sea (ECS). To accurately interpret the abundance of Nrt2 transcripts in situ, maximum and minimum expression levels were determined under conditions of nitrogen deprivation and ammonium addition, respectively. In August 2010, Nrt2 transcript levels in Skeletonema at the inner shelf region exhibited a mean of 111 mmole/(mole EFL); at the mid-shelf region, the mean Nrt2 mRNA levels were 298 mmole/(mole EFL), which was very close to the maximum levels observed under nitrogen starvation. By contrast, the Nrt2 transcript levels in Chaetoceros were low at all of the shelf locations, except at one station in the mid-shelf region. The cross-shelf mean was 2.86 mmole/(mole EFL), which was similar to the expression levels observed in cultured Chaetoceros under conditions of sufficient ammonium. Similar expression patterns were observed in diatoms in the southern ECS in June 2011, but the Nrt2 transcript levels in Skeletonema at the inner shelf region were reduced to a mean of 28.6 mmole/(mole EFL). Regression analysis indicated that cell abundance and Nrt2 expression were closely related to the nutricline depth in the coastward half of the southern ECS for Skeletonema but not for Chaetoceros. These results indicate that the evaluated species differ in nitrogen status, which may reflect their evolutionary strategies to survive in a fluctuating marine environment.

Bulk and amino acid nitrogen specific isotope data from particulate organic matter and mesozooplankton (1000-2000 µm) from the Mekong River plume and southern South China Sea
<p><strong><span><span>The mean trophic position (TP) of mesozooplankton largely determines how much mass and energy is available for higher trophic levels like fish. Unfortunately, the ratio of herbivores to carnivores in mesozooplankton is difficult to identify in field samples. Here we investigated changes in the mean TP of mesozooplankton in a highly dynamic environment encompassing four distinct habitats in </span></span></strong>the southern South China Sea:<strong> </strong><span>the </span>Mekong River plume, coastal upwelling region, shelf waters, and offshore oceanic waters<strong><span>. </span></strong><span>We used a set of parameters derived from bulk and amino acid nitrogen stable isotopes from particulate organic matter (POM) and four mesozooplankton size fractions to identify changes in the nitrogen source and structure of the planktonic food web across these habitats.</span> We found clear indications of a shift in N sources for biological production from nitrate in near-coastal waters towards an increase in diazotroph-N inputs in oceanic waters where diazotrophs shaped the phytoplankton community. The shift in N source was accompanied by a lengthening of the food chain (increase in the TP), which may provide further support for the connection between diazotrophy and the indirect routing of N through the marine food web. Our combined bulk and amino acid δ<sup>15</sup>N approach also allowed us to estimate the trophic enrichment (TE) of mesozooplankton across the entire regional ecosystem. When put in the context of literature values, our high TE of 5.1‰ suggested a link between ecosystem heterogeneity and the less efficient transfer of mass and energy across trophic levels.</p>
