Myrna Leung 1969 journal 38 July 17 (cont.) Papa Leon Tree, 150+ ft., Depto. Lima, Peru go back for Ray) I got stuck in the sand with the truck, but was soon aided by 4 Peruvians who pulled me out. July 18 Checked my Culbourn line. This time I got 9 MUS, 1 tail, and 2 Dryzomys. The majority of the traps were sprung and empty. I suspect that the Dryzomys are not being successfully caught by the museum speciales. The 2 I caught - one by the neck and 1 by a front foot - were still alive. We will try to get chromosomes from them. Ray caught 7 MUS in his line. We went to the study area to do more insect counts. It seems there is differential abundance of types of insects on the newer W slope than on the E slope. There are many more silverfish on the E slope, whereas on the W slope, where the Tillandsia isn't as buried, most of the new invertebrates are spiders + crickets. 3:30 pm We went back to the study area with the intention of staying there overnight. We did more invertebrate samples on the E side to get an average number for silverfish. Ray & I set out steel traps - he had 2 stations + I had four - they were baited with mouse carcasses + beef. In the evening we went and counted spider eye shine in squares in which the number of Tillandsia plants had been counted. D. Pearson
