Meijendel research 1953-1960

Study Extent

March 1953- March 1960

Sampling

Pitfalls without preservative. Emptied and collected once per week. Samples were stored in 70% alcohol and identified by researchers of the Animal Ecology group from the Leiden University in the years following the sampling program. Locations were recorded as Amersfoort coordinates.

Quality Control

After digitization data was checked via row sums and column sums; when all files were digitized we checked the input once more by row and column sums.

Method steps

1. Writing down the catches on paper (in the early 1970s), registering the catches in an excel file per species for all 7 years; and checking some parts of the resulting file in a random way.
2. Writing an R program for getting the data in the right format for GBIF.
3. Checking some parts of the resulting file in a random way.
