P. Brylski 1982 Journal 3.6 mi E, 10.1 mi N. Amboy, San Bernardino Co., Calif 17 March winter storm this year just left the southland, hence my 4-day delay in getting back out into the field. Flash Flood warnings were out for the desert. Definitely a jeopardy to this fledgling research project. The weather today was quite civil, mid 60s in temperature. 10-20mph winds, billowy cumulus clouds. White one. Tonight, the sky is clear, giving view to bright stars in the moonless sky. 9:30pm checked one line and brought in 4 ff (released 4 of them); no other captures. Three ff showed embryos, but very early in development: PVB 539,540 probably mated earlier this week. PVB 541 appears to be 7-14 days pregnant. #542 showed an abnormal growth on the kidney. Concernous? Temperature at 10pm is 6°C. 20 March 12noon Pulled up all 7 line traps. What a catch! All merriami individuals were sexed on the spot and most all fff released. Catalogued 34 merriami; 5 oof, 29 ff. In addition, 3 juveniles (or sub-adult?) were saved line and will be catalogued soon. 20 oof were released. Bringing total captures to round 60. Several females in the traps were dead from the cold and had bloated themselves (and [illegible] early development embryos) -- so these weren't catalogued. A fruitful trap-night. The full range of embryo sizes was seen. Modal or mean values are beyond me at this point, particularly since I must pack up and reach the Kelso Dunes and set trap lines.
