 northeastern Washington. Murrelet 54:7-8. 



• SYNAPTOMYS BOREALIS is described from Bunchgrass Meadows in NE Washington at 5000 

 ft. Area is a true bog/fen of over a square mile with a few small spruce and fir islands. Plants 

 present included: BETULA GLANDULOSA, CAREX LIMOSA, C. SCOPULORUM, 

 DROSERA ANGLICA. LYCOPIUM SITCHENSE, KALMIA POLIFOLIA, SCHEUCHZERLA 

 PALUSTRIS, SIBBALDIA PROCUMBENS, and SPHAGNUM. Authors list bird and herp spp 

 also present. Present on the site were piles of grass and sedge cuttings at the base of small shrubs 

 and along runways; most common cuttings were CAREX SCOPULORUM. A single bog 

 lemming was captured during 140 snaptrap nights on 10-11 July 1972. Suggest threats to 

 population may include: overgrazing, compaction of snow (destroying runways and nests) by 

 snowmobiles , and impoundments which could flood the area.

 PENNSYLVANICUS. Ecol. 65:382-393. 



• SYNAPTOMYS are excluded from preferred habitats by MICROTUS. The following patterns 

 were observed: 1) In undisturbed sympatric populations, microhabitat partitioning was observed 

 when habitat was marginal for voles. 2) Lemming microhabitat had more trees and shrubs when 

 voles were present. 3) If vole populations declined, lemmings shifted into habitat previously 

 occupied by voles. 4) Removal of voles from a grid resulted in immediate colonization by 

 lemmings. 5) A year following lemming removal, former lemming habitat remained empty despite 

 an increasing vole population. 6) Food of lemmings was less digestible than voles on grids where 

 both occurred. 7) When voles were removed from a grid, lemming diets became more similar to 

 voles (72 vs 37%).

 sphagnum bogs, occasionally dry or moist meadows.
