Childs 1955 Lemmus 2 July 5 Otlesout, Meade River, Alaska Found a ? under a oil drum. July 6 See jumnd. Evidence of great concentrate on the S side of the runway in area bulldozed up & invaded by moss only. Greatest seat concentrate I have ever seen. Depth of snow there may have been an important factor in concentrating them in one area. July 8 Had tremendous luck in T2 - 7 animals. This line parallels a marsh, lying on the east side of a low ridge. Drainage is good. Polygon ridges are not well developed. Grass is not abundant and some willow in present. Trapped both species at the same stake so there is some overlap in the use of runways. I now believe the seats to be much smaller than Lemmus and more core shaped. Scattered pellets are difficult to see. A careful search for them might reveal that they are more scattered and less collected into Scatoria (for Dicrostonyx) than Lemmus. July 9 Score at 2000 38 Lemmus; 15 Dicrostonyx; 8 microtus. The sub adults have been most abundant in the later catches in T2. This is probably due to their parents being caught at about the time of independence and the young being forced out to freeze for themselves. One of the small 97 was pregnant, an almost observe
