Eelgrass 2014 Site Survey Data Dataset Description: Methods and Sampling: <p>Twenty meter square plots (2 meters apart) were sampled at 50 eelgrass meadows ("sites") in summer 2014. Abiotic parameters were quantified in situ and/or using local monitoring station data. The epifaunal community was quantified as in Duffy et al. 2015. Seagrass density was quantified in 20cm diameter rings, and dry mass from 20 cm diameter cores which captured all above ground mass, and below ground to a depth of 20 cm. A three centimeter section from each of 5 shoots per plot was quantified for leaf carbon and nitrogen (processed at the Virginia Institute of Marine Science), while another 3 cm section was utilized for plant genetic analyses (processed by J. Olsen at the University of Groningen). Additional details are included in the Zostera Experimental Network 2014 survey handbook protocol, available upon request.</p>

Global biodiversity and functioning of eelgrass ecosystems (Zostera Experimental Network 2)

Global biodiversity and functioning of eelgrass ecosystems (Zostera Experimental Network 2)
<p><em>Description from NSF award abstract:</em><br />
This research will produce the second generation of a global collaborative research project, the Zostera Experimental Network (ZEN), to quantify the interacting influences of environmental forcing, biodiversity, and food-web perturbations on structure and functioning of eelgrass (<em>Zostera marina</em>) beds, the foundation of important but threatened coastal ecosystems worldwide. Partners at 40 sites in 14 countries will conduct parallel, standardized field sampling of producer and consumer biomass and diversity, and measure grazing and predation rates, to produce a global map of biodiversity, biomass distribution among trophic levels, and ecosystem processes in eelgrass habitats. Partners at a subset of core sites will conduct factorial experiments to characterize the interaction of nutrient loading, predator loss, and biogenic habitat structure (eelgrass density) in mediating producer growth and trophic processes in eelgrass. Finally, guided by the results from mechanistic experiments, the global field data will be used to test specific hypotheses about impacts of climate warming, nutrient loading, and declining biodiversity on eelgrass ecosystems via structural equation modeling, a uniquely powerful approach to dissecting complex interacting networks of causality. The proposed research will characterize in unprecedented detail how environmental forcing, biodiversity, and food-web processes interact to mediate functioning of a coastal ecosystem on a global scale. There are four general objectives:</p>
<p>1. Quantify linkages between eelgrass genetic diversity, growth, and provision of animal habitat;</p>
<p>2. Quantify the influence of eelgrass habitat structure on consumer-prey interactions, secondary production, and trophic transfer;</p>
<p>3. Identify mechanisms for the influence of grazer diversity on algal control;</p>
<p>4. Develop a global map of grazing and predation intensity to assess the relative importance of bottom-up and top-down forcing in eelgrass beds.</p>
<p>This program's integrated characterization of biodiversity, ecosystem state variables, and process rates across the globe is arguably unique in any marine system. It builds on promising results from the first generation of ZEN to allow for the first time a rigorous analysis of links between biodiversity and ecosystem functioning in a natural system on a global scale. As part of this analysis, the proposed research will provide the most comprehensive analysis yet of the controversial question of the relative importance of bottom-up and top-down forcing in seagrass ecosystems, an issue of fundamental importance to management and conservation.</p>
<p>Seagrasses and the many ecosystem services they provide are declining worldwide. This project's data on higher trophic levels and food-web interactions will provide a valuable and overdue complement to the many monitoring programs around the world that focus primarily on seagrasses and water quality, and will ultimately be made available to parameterize and test models of threatened seagrass ecosystems at a higher level of resolution ecological reality than previously possible. The success of the Zostera Experimental Network (ZEN) is evidenced by the continuation of all but one partner in the second generation (ZEN 2), and recruitment of nearly the same number of new partners to this global collaboration. This research will solidify and expand this network by more than doubling the number of participating sites, collaborating with parallel European Union and Japanese efforts, and integrating the world's largest and most successful seagrass restoration project at the Virginia Coast LTER site.</p>

dataset
<p>Twenty meter square plots (2 meters apart) were sampled at 50 eelgrass meadows ("sites") in summer 2014. Abiotic parameters were quantified in situ and/or using local monitoring station data. The epifaunal community was quantified as in Duffy et al. 2015. Seagrass density was quantified in 20cm diameter rings, and dry mass from 20 cm diameter cores which captured all above ground mass, and below ground to a depth of 20 cm. A three centimeter section from each of 5 shoots per plot was quantified for leaf carbon and nitrogen (processed at the Virginia Institute of Marine Science), while another 3 cm section was utilized for plant genetic analyses (processed by J. Olsen at the University of Groningen). Additional details are included in the Zostera Experimental Network 2014 survey handbook protocol, available upon request.</p>
<p>Methodology is available from: J. Emmett Duffy, et al. Biodiversity mediates top-down control in eelgrass ecosystems: A global comparative-experimental approach. 2015.

<p>Data were aggregated and quality checked manually and through use of analysis scripts. Biotic values are site means.</p>
<p><strong>BCO-DMO Processing:</strong><br />
- added conventional header with dataset name, PI name, version date<br />
- renamed some parameters to BCO-DMO standard<br />
- replaced . with _<br />
- replaced special characters with ascii characters<br />
- reformatted date from m/d/y to yyyy-mm-dd<br />
- reduced digits to right of decimal<br />
- sorted data by Latitude</p>

PI Supplied Instrument Name: Instrument Name: Automated DNA Sequencer Instrument Short Name:Automated Sequencer Instrument Description: A DNA sequencer is an instrument that determines the order of deoxynucleotides in deoxyribonucleic acid sequences.
PI Supplied Instrument Name: Instrument Name: CHN Elemental Analyzer Instrument Short Name:CHN_EA Instrument Description: A CHN Elemental Analyzer is used for the determination of carbon, hydrogen, and nitrogen content in organic and other types of materials, including solids, liquids, volatile, and viscous samples.
PI Supplied Instrument Name: PI Supplied Instrument Description:Used to measure salinity Instrument Name: Refractometer Instrument Short Name:Refractometer Instrument Description: A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry). The index of refraction is calculated from Snell's law and can be calculated from the composition of the material using the Gladstone-Dale relation.
In optics the refractive index (or index of refraction) n of a substance (optical medium) is a dimensionless number that describes how light, or any other radiation, propagates through that medium.
PI Supplied Instrument Name: PI Supplied Instrument Description:HOBO Pendant temperature loggers Instrument Name: Temperature Logger Instrument Short Name: Instrument Description: Records temperature data over a period of time.
PI Supplied Instrument Name: Instrument Name: Thermal Cycler Instrument Short Name:Thermal Cycler Instrument Description: A thermal cycler or "thermocycler" is a general term for a type of laboratory apparatus, commonly used for performing polymerase chain reaction (PCR), that is capable of repeatedly altering and maintaining specific temperatures for defined periods of time. The device has a thermal block with holes where tubes with the PCR reaction mixtures can be inserted. The cycler then raises and lowers the temperature of the block in discrete, pre-programmed steps. They can also be used to facilitate other temperature-sensitive reactions, including restriction enzyme digestion or rapid diagnostics.
