PISBEE, D.O. 1988 Peromyscus Californicus (1) Nashville Natural History Reservation, Monterey Co., Calif. (see acct. Jan 11) (below) Jan.7 #1142 ♀ SAD, nullip., perf. 28g. Ear-tagged. Grid RC, St 7,16 Blood, ear saline Jan 8 1146 ♀ SAD, nullip., imp. 32g. " - " " " 4/14. saline No sign of any fluorescent powder on this animal. 1147 ♂ SAD, TUD. 32.6g. " - " " " 4/13 saline No sign of any fluorescent powder on this animal. This morning I dusted #1079 with Red Powder, at station 5,14. She escaped to the west. I also caught her suspected mate #1944 at station 10,14 and bled him for prolactin assay. He had paint Red Powder in his ears and behind his ears 2130hrs - caught #1136 ♀ at station 10,11 covered with fresh RED Powder (ears, mouth, feet, genital region, tail) No sign of red any powder. Jan 9 #1152 ♂ SAD, TUD. 32g. Ear-tagged. Grid RC, St 5,11. Blood ear saliva collected #1952 - this animal is about to loose its ear tag (in left ear), so I toe-clipped it # OID. Jan 10 This and found #1079 ♀ dead in the trap at station 5,15. She was wet and there was no bait left in the trap. She had gone from 58g on 8 Jan to 48g today. Autopsy revealed 3 embryos (1lt, 2rt); two which were frozen in nitrogen for electrophoresis and 1 preserved in 70% alcohol. Tissues were frozen in nitrogen. The inside of her skin was pink from dusting her with RED powder. Apparently the powder stains the skin. Jan 11 Returned #1142 to lab last night to bleed this am. She had Red Powder on her ears and around her mouth, so she is probably offspring from #1079? However, the powder is very faint and possibly from secondary contact? (leg. contact with a groomer of 1079)
