Panels were exchanged every two weeks with clean panels for 12 months. Communities were recruited under the following treatments: full cage (i.e. reduced predation), partial cage (i.e. procedural cage control; ambient predation) and (c) no cage (i.e. ambient predation). Caging materials had a mesh size of 0.635 cm.&lt;/p&gt; &lt;p&gt;Experiments were initiated in Alaska in June 2015, California in May 2016, Mexico in June 2017, and Panama in December 2015.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;Sampling and analytical procedures: &lt;/strong&gt;&lt;/p&gt; &lt;p&gt;Following the recruitment period, communities were retrieved and examined under a stereoscope.

Community Effects of Competition and Predation across Latitude and Implications for Species Invasions https://osprey.bco-dmo.org/project/516723 Community Effects of Competition and Predation across Latitude and Implications for Species Invasions <p><em>Description from NSF award abstract:</em><br /> Global patterns of biodiversity demonstrate that most of the species on earth occur in the tropics, with strikingly fewer species occurring in higher-latitude regions. Biologists predict that this global pattern of species diversity is likely shaped by thee ecological interactions between species. Yet few detailed experimental data exist that demonstrate how species interactions influence natural communities from the tropics to the arctic. Therefore, a significant opportunity exists to transform our understanding of how these fundamental species interactions shape patterns of biodiversity across the globe. Furthermore, these species interactions have the strong potential to limit potentially harmful biological invasions by non-native species, which are often transported by human activities that can breach historical dispersal barriers, such as ocean basins and continents. Biological invasions can cause undesired ecological and economic effects and are considered one of the primary drivers of global change. Through extensive field research on marine ecosystems along the Pacific Coast of North and Central America, from the tropics to the subarctic, this project will study ecological factors that shape global patterns of diversity and limit biological invasions.</p> <p>Biologists have long theorized that the latitudinal diversity gradient may be shaped by stronger species interactions, such as competition and predation, occurring in the tropics than at higher latitudes. Prior research suggests that predation pressure is indeed stronger at lower latitudes, but it is unclear how interactive effects of predation and competition structure communities to maintain these diversity patterns in ecological time. This project represents an international research program to expand ecological understanding of species interactions across latitude. The objectives are to determine the relative influences of two primary species interactions, competition and predation, on patterns of species diversity, community assembly and sensitivity to species invasion. Field research will employ a large-scale experimental approach that focuses on sessile marine invertebrate communities across 47 degrees of latitude (over 7000 km). Experiments will manipulate levels of predation and competition for one year and will be conducted in four regions, ranging from the subarctic to the tropics: Alaska, California, Mexico, and Panama. Communities of sessile marine invertebrates, composed of both native and non-native species, will be examined iteratively under different predation and competition regimes to evaluate community dynamics. The relative importance of a suite of factors, including environmental conditions and recruitment rates, to interaction outcomes will be evaluated.</p> Competition and Predation across Latitude largerWorkCitation project eng; USA oceans -131.797 -79.5218 8.9128 55.4726 2015-01-03 2018-06-14 Eastern Pacific in four coastal regions: Ketchikan, Alaska; San Francisco, California; La Paz, Mexico; and Panama City, Panama 0 BCO-DMO catalogue of parameters from Recruitment composition of sessile marine invertebrate communities across latitude (Competition and Predation across Latitude) 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/863559.rdf Name: Region Units: unitless Description: <p>Region where each taxon was collected (Alaska, California, Mexico, Panama)</p> http://lod.bco-dmo.org/id/dataset-parameter/863560.rdf Name: Site_name Units: unitless Description: <p>Complete site name</p> http://lod.bco-dmo.org/id/dataset-parameter/863561.rdf Name: Site_code Units: unitless Description: <p>Unique site abbreviation (two letter code)</p> http://lod.bco-dmo.org/id/dataset-parameter/863562.rdf Name: Latitude Units: decimal degrees Description: <p>Latitude of site where communities recruited.
