Skeletal mineralogy of marine organisms shaped by seawater temperature and evolutionary history - a case study of cheilostome bryozoans

The record of CaCO3 biominerals serves as a valuable repository documenting Earth's evolutionary history and environmental changes. An in-depth understanding of the mineralogical diversity within calcifying organisms is essential for interpreting the evolutionary record of CaCO3 and evaluating the adaptability of biomineralizers to past and future environmental change. To offer insights into the relative importance of environment vs. phylogenetic history in determining mineralogy, this study explores the modern-day global distribution of mineralogies in cheilostome bryozoans.
Cheilostome bryozoans vary considerably in their mineral composition: in our dataset 65% of the species possess purely calcite skeletons, 15% exclusively employ aragonite, and 20% exhibit mixed (i.e., calcite and aragonite) mineralogies. Temperature is the predominant measured environmental factor influencing bryozoan skeletal mineralogy, accounting for 20% of its variability across species, when phylogenetic relat..., We employed X-ray diffraction (XRD) to analyze the skeletal mineral composition of 872 individual colonies, representing 437 bryozoan species, in terms of calcite/aragonite ratios. We integrated this data with equivalent published data, thus reaching 981 species, and applied linear models (LMs), generalized linear models (GLMs), and phylogenetic generalized least squares models (PGLSs), to investigate the influences of temperature, salinity, depth, and phylogenetic history on the mineralogy of nearly 1,000 cheilostome bryozoan species., , # Data from: Skeletal mineralogy of marine organisms shaped by seawater temperature and evolutionary history - a case study of cheilostome bryozoans

## Description of the data and file structure

The Bryozoan Mineralogy Database (BryoMinBase). The records for 5,328 bryozoan colonies, are classified as follows: 4,938 colonies of Cheilostomatida, 299 colonies of Cyclostomatida, 3 colonies of Ctenostomatida, and 88 unidentified colonies. Of these, 144 cases were excluded from the analyses and indicated in the \"Notes\" column. For Cheilostomatida, 4,595 colonies representing 981 species have associated environmental data, including temperature, salinity, and depth. Species names in the \"species_IDs_only_location_Ids\" column are derived from a combination of colonies identified at the species level (species_IDs_only) and those identified only to the genus level. It is assumed that colonies from different loca...
