Eelgrass (Zostera marina) diversity metrics from 15-month field experiment in Bodega Bay, CA starting in the summer of 2013

Abstract:

Field experiment assessing the relative importance of genotype richness, genetic relatedness, and trait diversity on eelgrass performance. The 15-month experiment was started in July of 2013 and ended in October 2015.

Methods & Sampling

Field experiment assessing the relative importance of genotype richness, genetic relatedness, and trait diversity on eelgrass performance. 41 genotypes across three tidal heights at five sites were collected in Bodega Harbor, California, USA in May 2012 and propagated in outdoor tanks at the UC Davis Bodega Marine Laboratory to produce enough shoots for deployment in a 15-month field experiment starting in the summer of 2013. More details can be found in Abbott et al., 2017 and Abbott et al., in press.

Location: Bodega Harbor, CA. Latitude: 38.32353 N Longitude: -123.04778 W.

Eelgrass collection locations can be found in the dataset: "Eelgrass transect information" https://www.bco-dmo.org/dataset/725435.

Physical and morphological traits of the eelgrass used in this experiment can be found in the dataset "Eelgrass traits" https://www.bco-dmo.org/dataset/725483 measured between March of 2013 and August of 2014.

Data Processing Description

BCO-DMO Data Manager Processing Notes:
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions
* rounded all numeric values with more than three decimal places to three decimal places
* changed values "ND" to "nd" indicating no data for BCO-DMO system compatibility
