After almost four years, the fruits of our Oregon State University graduate student biodiversity collaboration has paid off! Starting in fall 2011 as a NSF-sponsored Dimensions of Biodiversity Distributed Graduate Seminar, we have continued to work on our two projects and this summer we see both of our papers published in PLoS ONE!
Evaluating Temporal Consistency in Marine Biodiversity Hotspots
Patterns and Variation in Benthic Biodiversity in a Large Marine Ecosystem
Despite ample evidence from the terrestrial environment for a globally coherent pattern of increasing biodiversity towards the equator, patterns of marine biodiversity don't always follow this pattern and show inconsistencies in large-scale macroecological patterns of biodiversity. We explored taxonomic and functional biodiversity patterns for groundfish and benthic invertebrates along 15-degrees of latitude on the US West Coast, with data gathered from the same trawl survey as Piacenza & Thurman et al. 2015 (above). The patterns of bentic diversity are complex, whereby fish and invertebrate diversity differed most strongly along a depth gradient, rather than a latitudinal gradient. In particular, invertebrate diversity increased at depth, but fish diversity peaked at shallow depths along the continental shelf.
