Lemmus trimucronatus
21 may Barrow, Alaska
Sign of lemmings everywhere back of the
flat. We dug down to the surface in several
places and found runaways everywhere,
continues to form caverns as below.
[snow] 5000000000 [illegible] submitted by body heat
granular
27537 grams of feces
surface
No owls or jaegers seen although several
pellets were found.
23 may Took measel out to Heath ridge and central
marsh. Collected 91 lemmings by hand!
Three were caught by circling an area
of thin snow app. 200' in diameter and
slowly decreasing the circle. 24 were taken
by one such circle! glamorous gulls were
feeding on lemmings in central marsh. No
owls or jaegers. The sample of 91 was
6/87 to 297. Nearly all were adult pigs.
The few small ones appear sexually mature.
Wonder if these may be examples of retarded
growth?
25 May Had no luck with our collecting system
as snow either too deep or gone. Wonder
if the glazed, thin ice acted as lens
increasing heat and thereby concentrating
lemmings on 5/23. Those areas are all
free now.
