Data and code for a high-resolution summary of Cambrian to Early Triassic marine invertebrate biodiversity
<p>Data compilation and standardization were conducted through the Geobiodiversity Database from 2013 to 2017. The raw dataset contained 266,110 local Cambrian to Triassic records of 45,318 taxonomic units from 3,766 published stratigraphic sections. These were collected from all major Chinese tectonic plates. The authors spent three years verifying the taxonomic assignments into a consistent paleontological taxonomic classification system. Identifications to genus or higher taxonomic ranks were omitted. All non-marine fossil groups (e.g., plants, vertebrates, pollen, spores) were also removed. Species recovered from only a single locality were removed after a few test calculations in order to partially standardize the sampling and research efforts and avoid the "monograph effect". The final dataset retained after all standardization procedures included 116,060 local records of the stratigraphic ranges of 11,268 species in 3,112 published stratigraphic sections. </p> <p>The CONOP.SAGA program was designed for high-performance computing of geological time scale and biodiversity analysis in 2017. We designed a special hybrid algorithm that combined simulated annealing and a genetic algorithm to overcome the limitations of classic CONOP program designed by Pete Sadler.</p>
Data from: Quantifying Susceptibility of Marine Invertebrate Biocomposites to Dissolution in Reduced pH
Ocean acidification threatens many ecologically and economically important marine calcifiers. The increase in shell dissolution under the resulting reduced pH is an important and increasingly recognised threat. The biocomposites that make up calcified hardparts have a range of taxon-specific compositions and microstructures, and it is evident that these may influence susceptibilities to dissolution. Here, we show how dissolution (thickness loss) under both ambient and predicted end-century pH (≈7.6) varies between seven different bivalve mollusc and one crustacean biocomposite and investigate how this relates to details of their microstructure and composition. Over 100 days the dissolution of all microstructures was greater under the lower pH in the end-century conditions. Dissolution of lobster cuticle was greater than for any bivalve microstructure, despite its calcite mineralogy, showing the importance of other microstructural characteristics besides carbonate polymorph. Organic content had the strongest positive correlation with dissolution when all microstructures were considered, and together with Mg/Ca ratio, explained 80-90% of the variance in dissolution. Organic content, Mg/Ca ratio, crystal density and mineralogy were all required to explain the maximum variance in dissolution within only bivalve microstructures, but still only explained 50-60% of the variation in dissolution.
Data from: Strong population genetic structure in a broadcast-spawning Antarctic marine invertebrate
Although studies of population genetic structure are commonplace, a strong bias exists towards species from low latitudes and with relatively poor dispersal capabilities. Consequently, we used 280 Amplified Fragment Length Polymorphism (AFLP) bands to explore patterns of genetic differentiation among eight populations of a high latitude broadcast-spawning marine mollusc, the Antarctic limpet Nacella concinna. Over three hundred individuals were sampled along a latitudinal gradient spanning the Antarctic Peninsula from Adelaide Island to King George Island (67º–62º S), then to Signy Island (60ºS) and South Georgia (54ºS). Populations from the Antarctic Peninsula exhibited little genetic structure, but were themselves strongly differentiated from both Signy and South Georgia. This finding was analytically highly robust and implies the presence of significant oceanographic barriers to gene flow in a species long regarded as a classic example of a widely-dispersing broadcast-spawner.
