School Malaise Trap Program - Fall 2015

We were scrambling a little in the last weeks but here they are (and all the participating schools have them already) - the results of our School program fall run:

In 64 traps students collected 750 specimens on average for the two week period in September. Our collections group sorted 47,711 specimens and selected 16,798  to be barcoded. Our final dataset was made up of 15,043 DNA Barcodes (not all  worked and short barcodes were discarded). Using BOLDs BIN analysis we could  determine that the record number of 3,515 species were collected over the two week period of the program, 247 of which were brand new to BOLD. The map below shows all of these collection sites, which include elementary schools, secondary schools, and comparison sites (blue markers). You might notice that we also had some participants from the US. A shout out to our friends from some of the San Diego Libraries.

Our overall pie chart shows the typical species composition (largely grouped in orders) although this time the dipterans are not as predominant as they were in other years and runs. We caught almost as many different hymenopteran species. Mind you this is not a figure that corrects for abundance as flies clearly dominate each catch by their numbers.

Once more a great accomplishment by a large number of young citizen scientists. After three years still many surprises and new finds. Impressive.
