String acquisition_description
"We manipulated the presence and absence of all three species in a factorial
design that yielded eight treatments and comprised four levels of diversity:
three consumers (crabs + snails + fungus), two consumers (crabs + snails,
crabs + fungus, snails + fungus), one consumer (crabs or snails or fungus),
and no consumers. Sixty-four plots were selected (mean Spartina density: 120.8
\\u00b1 6.2 stems per m2).
Ecosystem Function 1: NPP. To determine the effect of experimental consumer
variety on NPP, net Spartina production was estimated by measuring change in
live aboveground plant mass from the beginning to end of the experiment.
Ecosystem Function 2: Decomposition Rate. We quantified the effect of consumer
variety on marsh decomposition rate by deploying a plug consisting of three
dead Spartina stems zip tied to a plastic flag post.
Ecosystem Function 3: Infiltration Rate Measurement. We quantified the effect
of consumer variety on marsh infiltration at the conclusion of the experiment
by using a double-ring infiltrometer.
Assessing Multifunctionality. To assess whether snail, crab, and fungi
consumers differed in their ability to perform all measured functions
simultaneously, we calculated an average multifunctionality index for each
treatment. This method is a simple technique involving averaging standardized
values of multiple functions into a single index. For each of the three
functions, we used a \\u201cstandardization by maximum observed value\\u201d
approach where we defined maximum functioning as the mean of the highest three
values from all 64 plots in the experiment for each function, giving us one
maximum for each function regardless of treatment. Using this maximum, plot
data were recorded as the percent of that maximum for each function, creating
a scaled \\u201cpercent functioning\\u201d value for each individual plot.

"In terrestrial communities, grazer-facilitation of fungal disease in plants has been studied for over a century. Despite the prevalence of this interaction in terrestrial systems, it was not considered relevant to the structure of marine plant communities until the investigator's recent work in salt marshes. By manipulating both grazer and fungal presence, he demonstrated that snail grazing and subsequent fungal infection in live grass led to drastic reductions in plant growth and, at high grazer densities, destruction of canopy. If grazer promotion of fungal disease in marine plants is not limited to marshes (as suggested by preliminary data from a world-wide survey of 4 marine plant ecosystems) then small grazers that take small bites out of plants could be exerting similarly strong, but undetected control over marine plants globally. In addition, since physical stress commonly reduces plant immune responses, intensifying multiple stressors associated with marine global change could intensify and destabilize these unstudied grazer-disease-plant interactions. To test the global generality of this potentially keystone ecological interaction, this project will answer the following questions with a combination of multi-site surveys and manipulations across 4 ecosystems spanning 2 continents: 1) Is grazer facilitation of fungal disease in marine plants a common but overlooked interaction? 2) What is the resultant impact of grazer-facilitated fungal infection on marine plant growth? 3) How do multiple stressors impact the strength of grazer facilitation of fungal disease in marine plants? The work represents a transformative step forward in our understanding of plant-grazer interactions in marine ecosystems as it fills a > 100-year intellectual gap in our understanding of top-down control in marine plant ecosystems: Do small grazers commonly facilitate fungal disease in marine plants and does this interaction suppress plant growth?
Evidence for this cryptic, yet powerful mechanism of grazer regulation of marine plants will compel marine ecologists to reevaluate our understanding of top-down control and lead to widespread integration of disease dynamics in marine food web ecology.
The consequences of marine plant ecosystem health are far-reaching for humans, since these communities provide many essential services. Results from this study will allow managers to better predict effects of disease and global change on marine plant systems and formulate effective strategies for conservation. To help integrate plant disease dynamics into marine ecology and conservation, the investigator will: (1) produce an edited volume on Food Webs and Disease in Marine Ecosystems and (2) work closely with The Nature Conservancy to incorporate findings into their global marine learning exchanges. In addition, an integrated educational plan will increase student: (1) understanding of disease and food web dynamics in marine ecosystems and (2) consideration of marine science careers.";

Data Access Protocol (DAP) and its
selection constraints.
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
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
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").
