Dataset type
This dataset that contains primary occurrence data for species.
Description
Occurrences in this dataset on Swedish Insects have been identified from specimens collected from for the Swedish Malaise Project (SMTP), an inventory funded by the Swedish Species Information Centre (ArtDatabanken). These records comprise the foundation for recent estimates on the size and composition of the Swedish insect fauna, published herein as sample-based datasets.
Geographic Description
The study area is within the political territory of Sweden, including the islands of Öland and Gotland.
Data quality
The occurrence datasets returned to SMTP staff were validated and cleaned, with names used for identifications matched to those of the national species checklist (DynTaxa) and the European species checklist (Fauna Europaea).
Methods
Raw trap samples were sorted by taxonomy into increasingly restrictive units, resulting in more than 300 taxonomic fractions (see http://www.stationlinne.se/en/research/the-swedish-malaise-trap-project-smtp/taxonomic-units-in-the-smtp/), which were sent to collaborating experts for identification. Over 100 taxonomic experts from around the world were involved in identifying this material, which represents 165,000 specimens.
These datasets were reorganized into 79 datasets, each corresponding to a set of samples of a particular taxon or assemblage of taxa (“analysis taxon”) processed by a different expert or group of experts. The analysis taxa mostly correspond to families or subfamilies of Diptera and Hymenoptera, and orders or parts of orders for other insect groups. The data analyzed represent all the cleaned data files that were available in the spring of 2017. In total, there are 127 files, most of which contain abundance data (117 files) but some of which only provide incidence data (10 files).
The analyzed information is estimated to represent from 2 to 67 % of the entire catch of each analysis taxon (Table S4). In total, the abundance data comprise 157,225 specimens (30,643 records) identified to 3,916 taxa. The incidence data represent another 1,516 observations and 279 taxa. The incidence data roughly corresponds to 7,800 specimens, if this material contained the same average number of specimens per species and sample as the material covered by the abundance data.
