"These data are described in detail in Sotka et al., 2018. From May until
October 2015, we collected live thalli at each of 40 populations: 15 Japanese
(six source and nine nonsource), five western North American, 10 eastern North
American, and 10 European populations. We exposed a haphazardly chosen set of
approximately 20 thalli per population to extreme heat (1, 2, and 4 hr in
40\\u00b0C), extreme cold (45, 75, and 105 min at \\u221220\\u00b0C), and low
salinities (8 days at 0, 5, and 10 ppt). For the heat tolerance assay, four
apices per thallus were individually placed into unsealed 2- ml
microcentrifuge tubes containing 175 \\u03bcl of seawater. A control apex was
kept in a 15\\u00b0C growth chamber, while three apices were placed in a
40\\u00b0C water bath for 1, 2, and 4 hr. For the cold tolerance assay, four
apices were independently placed into sealed 250 \\u03bcl PCR tubes containing
200 \\u03bcl seawater. A control apex was kept in a 15\\u00b0C incubator, while
three apices were placed in a \\u221220\\u00b0 C freezer for 45, 75, and 105
min. Apices were then placed into randomly assigned wells of 12- well tissue
culture plates (2.21- cm- diameter wells) filled with 4 ml of seawater and
incubated at 15\\u00b0C for 8 days with a 12- hr light/dark cycle. For the
salinity tolerance assay, four apices were independently placed directly into
the 12- well tissue culture plates filled with 4 ml of seawater at a titration
of salinities diluted to 0, 5, and 10 ppt, with 30 ppt serving as a control.
Every 2 days for 8 days, we changed water and assessed thallus bleaching
(i.e., loss of photosynthetic pigments; Figure S2) as a proxy of mortality,
itself an important component of fitness. We generated a Bleaching Score (BS),
where \\u201c1\\u201d indicated no bleaching, \\u201c2\\u201d indicated partial
bleaching or color change to pink or white, and \\u201c3\\u201d indicated full

"Description from NSF award abstract:
Biological introductions, defined as the establishment of species in geographic regions outside the reach of their natural dispersal mechanisms, have dramatically increased in frequency during the 20th century and are now altering community structure and ecosystem function of virtually all marine habitats. To date, studies on marine invasions focus principally on demographic and ecological processes, and the importance of evolutionary processes has been rarely tested. This knowledge gap has implications for management policies, which attempt to prevent biological introductions and mitigate their impacts. The Asian seaweed Gracilaria vermiculophylla has been introduced to every continental margin in the Northern Hemisphere, and preliminary data indicate that non-native populations are both more resistant to heat stress and resistant to snail herbivory. The project will integrate population genetics, field survey and common-garden laboratory experiments to comprehensively address the role of rapid evolutionary adaptation in the invasion success of this seaweed. Specifically, the PIs will answer the following. What is the consequence of introductions on seaweed demography and mating systems? How many successful introductions have occurred in North America and Europe? Where did introduced propagules originate? Do native, native-source and non-native locations differ in environmental conditions? Do native, native-source and non-native populations differ in phenotype?
The intellectual merit of this project is based on three gaps in the literature. First, while biological invasions are widely recognized as a major component of global change, there are surprisingly few studies that compare native and non-native populations in their biology or ecology. Native and non-native populations will be surveyed in a similar manner, allowing assessment of differences in population dynamics, mating system, epifaunal and epiphytic communities, and the surrounding abiotic and biotic environment. Second, G. vermiculophylla exhibits a life cycle typical of other invasive species (including some benthic invertebrates), yet we still lack data on the effects of decoupling the haploid and diploid stages on genetic structure, and in turn, on the evolvability of their populations. Finally, this project will provide unequivocal evidence of an adaptive shift in a marine invasive. To our knowledge, such evolutionary change has been described previously for only a complex of marine copepod species. G. vermiculophylla will serve as a model for understanding evolution in other nuisance invasions, and perhaps lead to novel methods to counter future invasions or their spread.";

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.

Tabledap request URLs must be in the form
For example,
Thus, the query is often a comma-separated list of desired variable names, followed by a collection of constraints (e.g., variable<value), each preceded by '&' (which is interpreted as "AND").

For details, see the tabledap Documentation.
