(Version 1) Version Date 2023-03-20 [if applicable, indicate subset used]. doi:10.26008/1912/bco-dmo.891835.1 [access date] Methods and Sampling: &lt;p&gt;To assess whether faunal density patterns across landscapes were driven by larval settlement, larval fishes and crab megalopa were sampled seven times from June to August 2018 on Oscar Shoal and an adjacent unnamed shoal in Back Sound, NC, USA (34°42′20&quot; N to 34°41′60&quot; N, 76°36′ 15&quot; W to 76°35′17&quot; W) using Standardized Monitoring Units for the Recruitment of Fishes (SMURFs; Ammann 2004). This brackets the seasonal timing of settlement by the majority of species that occupy local seagrass as a nursery habitat (Baillie et al., 2015). SMURFs were created from 2.5-centimeter (cm) mesh VEXAR, zip-tied to create a 1-meter long, 0.2-meter diameter cylinder with folded-end closures. To facilitate settlement and accommodate various settler sizes, each cylinder was stuffed with two sizes of plastic mesh: 3 square meters of 5 cm × 7.5 cm and 5 square meters of 1 centimeter&lt;sup&gt; &lt;/sup&gt;× 1-centimeter mesh. SMURFs were secured to each landscape by a 20-centimeter sand screw and a 25-centimeter paracord line attached to the underside of the sampling unit. Floats were attached to cylinder ends for added buoyancy and to suspend the SMURFs above the seafloor.&lt;/p&gt; &lt;p&gt;To examine how settlement rates across landscapes differed depending upon the amount of immediately surrounding artificial seagrass, each SMURF was positioned at the 'center' of the largest ASU patch (as estimated for each irregular shape) in each landscape. SMURFs were deployed for 48 hours to maximize larval collection (Ammann, 2004) while minimizing biofouling (Tavernetti et al., 2009). After the first deployment cycle, it was noted that SMURFs retrieved closer to sunrise had higher settler abundances. Subsequent deployments were therefore timed to coincide with a 4-hour collection window surrounding sunrise. Upon retrieval, 5-gallon buckets of water were poured over each SMURF into a collection bin while the SMURF was shaken and rotated. This process was repeated a minimum of three times or until no additional fauna were observed being washed into the collection bin. Samples were sieved (0.5-millimeter mesh) and collected fauna were frozen for later identification and enumeration in the lab. All SMURFs were rinsed with fresh water and dried by sunlight before redeployment.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Known Issues:&lt;/strong&gt;&lt;br /&gt; Time_Out data are commonly missing.

Collaborative Research: Habitat fragmentation effects on fish diversity at landscape scales: experimental tests of multiple mechanisms https://osprey.bco-dmo.org/project/714026 Collaborative Research: Habitat fragmentation effects on fish diversity at landscape scales: experimental tests of multiple mechanisms <p>Amount and quality of habitat is thought to be of fundamental importance to maintaining coastal marine ecosystems. This research will use large-scale field experiments to help understand how and why fish populations respond to fragmentation of seagrass habitats. The question is complex because increased fragmentation in seagrass beds decreases the amount and also the configuration of the habitat (one patch splits into many, patches become further apart, the amount of edge increases, etc). Previous work by the investigators in natural seagrass meadows provided evidence that fragmentation interacts with amount of habitat to influence the community dynamics of fishes in coastal marine landscapes. Specifically, fragmentation had no effect when the habitat was large, but had a negative effect when habitat was smaller. In this study, the investigators will build artificial seagrass habitat to use in a series of manipulative field experiments at an ambitious scale. The results will provide new, more specific information about how coastal fish community dynamics are affected by changes in overall amount and fragmentation of seagrass habitat, in concert with factors such as disturbance, larval dispersal, and wave energy. The project will support two early-career investigators, inform habitat conservation strategies for coastal management, and provide training opportunities for graduate and undergraduate students. The investigators plan to target students from underrepresented groups for the research opportunities.</p> <p>Building on previous research in seagrass environments, this research will conduct a series of field experiments approach at novel, yet relevant scales, to test how habitat area and fragmentation affect fish diversity and productivity. Specifically, 15 by 15-m seagrass beds will be created using artificial seagrass units (ASUs) that control for within-patch-level (~1-10 m2) factors such as shoot density and length. The investigators will employ ASUs to manipulate total habitat area and the degree of fragmentation within seagrass beds in a temperate estuary in North Carolina. In year one, response of the fishes that colonize these landscapes will be measured as abundance, biomass, community structure, as well as taxonomic and functional diversity. Targeted ASU removals will then follow to determine species-specific responses to habitat disturbance. In year two, the landscape array and sampling regime will be doubled, and half of the landscapes will be seeded with post-larval fish of low dispersal ability to test whether pre- or post-recruitment processes drive landscape-scale patterns. In year three, the role of wave exposure (a natural driver of seagrass fragmentation) in mediating fish community response to landscape configuration will be tested by deploying ASU meadows across low and high energy environments.</p> Habitat Fragmentation largerWorkCitation project eng; USA biota oceans -76.603 -76.589 34.701 34.707 2018-06-07 2018-08-17 North Carolina 0 BCO-DMO catalogue of parameters from Settlement rates of fishes and crab megalopa within Artificial Seagrass Units (ASU) in Back Sound, NC from June to August 2018 Biological and Chemical Oceanography Data Management Office (BCO-DMO) Unavailable 508-289-2009 WHOI MS#36 Woods Hole MA 02543 USA info@bco-dmo.org http://www.bco-dmo.org Monday - Friday 8:00am - 5:00pm For questions regarding this resource, please contact BCO-DMO via the email address provided. pointOfContact http://lod.bco-dmo.org/id/dataset-parameter/891990.rdf Name: Site_ID Units: unitless Description: <p>Artificial seagrass unit (ASU) landscape name (Percent cover value-Percolation probability value)</p> http://lod.bco-dmo.org/id/dataset-parameter/891991.rdf Name: Latitude Units: decimal degrees Description: <p>Latitude North (South is negative) of sampling site</p> http://lod.bco-dmo.org/id/dataset-parameter/891992.rdf Name: Longitude Units: decimal degrees Description: <p>Longitude East (West is negative) of sampling site</p> http://lod.bco-dmo.org/id/dataset-parameter/891993.rdf Name: Per_cov Units: percent (%) Description: <p>Percent cover of ASUs in a 234 square meter landscape footprint (10, 22.5, 35, 47.5, 60)</p> http://lod.bco-dmo.org/id/dataset-parameter/891994.rdf Name: Frag Units: unitless Description: <p>ASU landscape fragmentation per se indexed by percolation probability (0.1, 0.225, 0.35, 0.475, 0.59)</p> http://lod.bco-dmo.org/id/dataset-parameter/891995.rdf Name: Date_Out Units: unitless Description: <p>Date of SMURF retrieval</p> http://lod.bco-dmo.org/id/dataset-parameter/891996.rdf Name: Time_Out Units: unitless Description: <p>Time of SMURF retrieval</p> http://lod.bco-dmo.org/id/dataset-parameter/891997.rdf Name: Sci_name Units: unitless Description: <p>Scientific name of fauna species</p> http://lod.bco-dmo.org/id/dataset-parameter/891998.rdf Name: N Units: unitless Description: <p>Number of fauna species caught</p> http://lod.bco-dmo.org/id/dataset-parameter/891999.rdf Name: Length Units: millimeters (mm) Description: <p>Total length of fauna</p> http://lod.bco-dmo.org/id/dataset-parameter/892000.rdf Name: Settler Units: unitless Description: <p>Is this fauna in the settler/larval stage?
