Dolichopodidae of Portugal - dataset 2009-2018

Dataset type

Deze dataset bevat primaire waarnemingsgegevens voor soorten.

Beschrijving

A first comprehensive account on the dolichopodid fauna (Diptera: Dolichopodidae) of Portugal is presented here as the result of multiple surveys by primarily Portuguese researchers between 2009 and 2016. All mainland Portuguese provinces and all districts but one (Évora) were investigated. A total of 761 dolichopodid samples were collected in 278 sampling sites distributed over 87 municipalities and 182 localities, with nearly ¾ of the samples gathered by sweepnet. In terms of generic representation, the Portuguese dolichopodid fauna occupies an intermediate position between those of northwestern European and other Mediterranean countries. Despite the large amount of data gathered, the dolichopodid fauna of Portugal remains insufficiently known and a considerable number of additional known and new species can be expected with continued sampling. A more exhaustive description of the dataset and the results of the surveys can be found in Pollet et al. (2019). We have released this dataset to the public domain under a CC-BY licence. We would appreciate it if you follow the GBIF citation guidelines https://www.gbif.org/citation-guidelines).

Gegevenskwaliteit

There was little need for any quality control during the sampling phase of this project. Collecting was mainly executed in promising sites for Diptera. A subsample of representative Diptera species (incl. Dolichopodidae) was systematically retrieved from the sweepnet by Rui Andrade and Ana Conçalves (principal collectors), whereas all Dolichopodidae were retained by Marc Pollet and Anja De Braekeleer. All samples were stored in 75% alcohol solution in cool and dark conditions.

Methoden

Data for this dataset are retrieved, unified and standardized from source data through a series of RMarkdown scripts and Openrefine scripts that are versioned on GitHub https://github.com/inbo/data-publication/tree/master/datasets/portugal-dolichopodidae-occurrences) and which include the following steps:Standardize the dataset to Darwin Core, sampling event dataset type. Containing a sample core and a occurrences extension.Conversion of the original coordinates to decimal coordinates, WGS84The resulting Darwin Core data files are uploaded to the INBO IPT and documented with metadata.The dataset is published and registered with GBIF.
