Ribble, D.O. 1984 Peromyscus californicus 46 Hastings Reservation, Monterey Co., Calif July 21 This PM on GRID RC we caught 1587, ?, SAD, st 5,17 with Blue-Green (continuation) visible in her ears. This PM we also set up a dyadic encounter between O?0110 and Lab F 1491 between station 7,12 and 6,12. (O?0110 was caught at 7,12 and we set up the arena at the nearest flat spot). F-1491's smear this am was 80% leukocytes and 20% nucleated epithelial cells. July 22 Returned to do the test at 0450h. She O? had dug under the divider and both mice were on the same side - We pulled out the divider and watched them for 20min. They remained huddled with the F on the back of the male for the entire 20min - obviously this test stinks. At death the F's smear indicated 85% leukocytes, 15% nucleated epithelial cells with no sign of sperm. This AM on the GRID we dusted F 1364, post-lact, st 6,13 with Golden Brown. #1708?
