Vermetid Counts on Long Term Vermetid Removal Reefs
<div><p>This dataset contains counts of the vermetid species <em>Ceraesignum maximum</em> at each Long Term Vermetid Removal (LTVR) Reef at the "TOW" site in Moorea, French Polynesia (-17.4745,-149.7925). The surveys were conducted between 2012 and 2014 as part of an ongoing census. These data are meant to provide contextual information for how vermetids affect reef communities. </p>
<p>Long Term Vermetid Removal (LTVR) Reef sites in this project are manipulated reefs characterized in the <a href="https://www.bco-dmo.org/dataset/645827" target="_blank">Long Term</a><a href="https://www.bco-dmo.org/dataset/645827" target="_blank"> Reef Physical Characteristics</a> dataset.</p>
<p>Reefs labeled "TOW" in this dataset, numbered 129-144, are a subset of a larger number of Long Term Reefs (LTR) that were monitored as part of the project "Cryptic density dependence: the effects of spatial, ontogenetic, and individual variation in reef fish" beginning in 2003. This long term study continues to monitor those reefs in addition to reefs 193-198 starting in 2012. Data for these reefs between the years 2003 and 2009 can be found on the project site <a href="http://www.bco-dmo.org/project/540423" target="_blank">http://www.bco-dmo.org/project/540423</a>.</p>
<p><strong>Location:</strong> Moorea, French Polynesia (17.48 degrees S, 149.82 degrees W)</p>
