Recruitment composition of sessile marine invertebrate communities across latitude (Competition and Predation across Latitude)

Abstract:

Composition of newly recruited communities of sessile marine invertebrates from coastal sites across a latitudinal gradient spanning the subarctic to the tropics. Caging treatments were employed to test the effect of predation on recruitment. Monitoring began in Alaska in June 2015, California in May 2016, Mexico in June 2017 and Panama in December 2015.

Description

Methods & Sampling

Methodology:

Marine invertebrates recruited onto PVC settlement panels (14 x 14cm) that were hung face down on floating docks one meter below the water surface at local marinas at three coastal sites in each region (Alaska, California, Mexico, Panama). 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.

Experiments were initiated in Alaska in June 2015, California in May 2016, Mexico in June 2017, and Panama in December 2015.

Sampling and analytical procedures:

Following the recruitment period, communities were retrieved and examined under a stereoscope. Newly recruited communities were assessed for number and identity of individuals. Recruitment was quantified on a standardized area of the panel (100 cm2 on a pre-assigned corner). Individuals were classified into distinct sessile morpho-taxonomic taxa based on a combination of growth form and taxonomy.
