Illuminating the planktonic stages of salmon lice: a unique fluorescence signal for rapid identification of a rare copepod in zooplankton assemblages.
<p>The Excitation Emission Matrix (EEM) measurements were taken with Shimadzu's proprietary software ‘LabSolutions RF’. All files are in the exported csv format with columns representing the excitation wavelengths and rows the emission wavelengths. Wavelengths range from 200-600 nm with a 2 nm increment. Fluorescence intensity was influenced by the fluctuating number of animals in the path of the excitation beam during the 5 minute measurement. We compensated for this artefact by repeating measurements of each sample five times, calculating the mean, and applying a smoothing function which found the median value within 10 nm. The fluorescence intensity was further normalized on a 0 to 1 scale by dividing intensity by the maximum fluorescence within each EEM measurement.</p> <p>Supplemental Table 1. The metadata of EEM measurements. The measurements were used for the spectrum section analysis and correspond to those depicted in Figures 2, 3, 4, & 5. See sections 3.1, 3.1.1, & 3.1.2. The Sample column indicates which lab culture cohort the sea lice came from (BGO*), which wild caught fish sample they came from (WC*), or the sampling date of non-target copepods (DDMMYY). The filename of each mean measurement is listed and indicates the first of 5 repeated measurements. Corresponding files can be found in the deposited.csv files at Zendo. In those files, data columns represent the excitation wavelengths, 200nm to 600nm increasing in 2 nm increments. Likewise, the rows represent the emission wavelengths. NaN’s are present where scattering layers were removed. All fluorescence intensity values are normalized to the maximum within each EEM.</p>

Data from: A metagenetic approach for revealing community structure of marine planktonic copepods
Marine planktonic copepods are an ecologically important group with high species richness and abundance. Here, we propose a new metagenetic approach for revealing the community structure of marine planktonic copepods using 454 pyrosequencing of nuclear large subunit ribosomal DNA. We determined an appropriate similarity threshold for clustering pyrosequencing data into molecular operational taxonomic units (MOTUs) using an artificial community containing 33 morphologically identified species. The 99% similarity threshold had high species-level resolution for MOTU clustering but overestimated species richness. The artificial community was appropriately clustered into MOTUs at 97% similarity, with little inflation in MOTU numbers and with relatively high species-level resolution. The number of sequence reads of each MOTU was correlated with dry weight of that taxon, suggesting that sequence reads could be used as a proxy for biomass. Next, we applied the method to field-collected samples, and the results corresponded reasonably well with morphological analysis of these communities. Numbers of MOTUs were well correlated with species richness at 97% similarity, and large numbers of sequence reads were generally observed in MOTUs derived from species with large biomass. Further, MOTUs were successfully classified into taxonomic groups at the family level at 97% similarity; similar patterns of species richness and biomass were revealed within families with metagenetic and morphological analyses. At the 99% similarity threshold, MOTUs with high proportions of sequence reads were identified as biomass-dominant species in each field-collected sample. The metagenetic approach reported here can be an effective tool for rapid and comprehensive assessment of copepod community structure.
