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: Sporadic genetic connectivity among small insular populations of the rare geoendemic plant Caulanthus amplexicaulis var. barbarae (Santa Barbara Jewelflower)
Globally, a small number of plants have adapted to terrestrial outcroppings of serpentine geology, which are characterized by soils with low levels of essential mineral nutrients (N, P, K, Ca, Mo) and toxic levels of heavy metals (Ni, Cr, Co). Paradoxically, many of these plants are restricted to this harsh environment. Caulanthus ampexlicaulis var. barbarae (Brassicaceae) is a rare annual plant that is strictly endemic to a small set of isolated serpentine outcrops in the coastal mountains of central California. The goals of the work presented here were to 1) determine the patterns of genetic connectivity among all known populations of Caulanthus ampexlicaulis var. barbarae, and 2) estimate contemporary effective population sizes (Ne), in order to inform ongoing genomic analyses of the evolutionary history of this taxon, and to provide a foundation upon which to model its future evolutionary potential and long-term viability in a changing environment. Eleven populations of this taxon were sampled, and population-genetic parameters were estimated using 11 nuclear microsatellite markers. Contemporary effective population sizes were estimated using multiple methods and found to be strikingly small (typically Ne < 10). Further, our data showed that a substantial component of genetic connectivity of this taxon is not at equilibrium, and instead showed sporadic gene flow. Several lines of evidence indicate that gene flow between isolated populations is maintained through long-distance seed dispersal (e.g. > 1 km), possibly via zoochory.
