Sample discarded; see below. Steve and I decided that soil samples will be replaced in the Berlese funnels once every 6 days. This amount of time will dry the samples completely, cause everything that will emerge to do so or dye in the soil. He wanted some from pool edge so 8 of the 16 taken from central marsh were discarded. Note: Hand picked 4 August: found 4 P. hannai larvae - 16mm, 12mm, 11mm, 9mm. = 80% efficiency (16/20) with berlesee extraction.
