An updated dataset of the global occurrence of the Atlantic blue crab Callinectes sapidus Rathbun, 1896 (Brachyura: Portunidae)|物种分布数据集|入侵生态学数据集

The Atlantic blue crab Callinectes sapidus is a portunid native to the western Atlantic, from New England to Uruguay. The species was introduced in Europe in 1901 and in recent years it has become invasive; additionally, a significant northward expansion has been emphasized also in its native range. Here we present a harmonized global compilation of occurrences of the Atlantic blue crab Callinectes sapidus from native and non-native distribution ranges. Data are derived from online databases (GBIF, BISON, OBIS, and iNaturalist) as well as from peer-reviewed literature and unpublished sources gathered from personal communications and from available-on-request databases either directly maintained by the Hellenic Centre for Marine Research (HCMR; https://www.hcmr.gr), or connected with the HCMR, such as the Ellenic Network on Aquatic Invasive Species (ELNAIS; https://elnais.hcmr.gr). The dataset consists of 40,388 geo-referenced occurrences, 39,824 from native and 564 from non-native ranges, recorded in 53 countries. It contains taxonomic information (i.e., scientific name together with the name of who described the taxon originally complemented by the unique identifier of the species provided by the World Register of Marine Species - WoRMS; www.marinespecies.org), the sources from which the records were collated with the original identification codes if available, spatial and temporal information (i.e., coordinates in decimal degrees and year of record; if available also the month and day of record were included), and the country where the occurrences were recorded. In addition, flagging fields were included to categorise i) the status of the species at the record’s location (i.e., native or non-native) supplemented by notes identifying uncertain taxonomic identifications and records associated with unsuccessful introductions; ii) the most recent records with different coordinates to the third decimal, complemented by an additional field flagging each entry with unique coordinates with a progressively increasing integer, while less recent records in the same location are flagged by the same integer and iii) records located under fully marine conditions, in-land records, and those located in coastal areas. The dataset is complemented by a complete list of literature sources, including permanent identifiers (bibliographic Citation DOI) if available, a table describing the details of each flagging field, and a list of notes related with outliers and unsuccessful intentional introductions outside the native range. Notes are numbered according to the flags included in the dataset.<br>
