White Pine Weevil Attack on White Spruce: A Survival Time Analysis [PDF]

Ecological Applications, 2000
The survival time of a white spruce tree (Picea glauca (Moench) Voss) with respect to the attack by the white pine weevil (Pissodes strobi (Peck)) was defined as the number of years until an attack occurred. In this context, resistant trees are those capable of delaying attacks rather than preventing attacks.

The Interaction Between Masting and Fire Is Key to White Spruce Regeneration [PDF]

Ecology, 2005
: We used the mast-seeding tree Picea glauca (white spruce) to examine whether the timing of mast years relative to fire had a lasting effect on the density and timing of regeneration. We studied 17 fires that occurred in mast years and in years with low

Inheritance of plastids in interspecific hybrids of blue spruce and white spruce

Theoretical and Applied Genetics, 1989
Chloroplast DNA (cpDNA) was purified from blue spruce (Picea pungens Engelm.) and white spruce [P. glauca (Moench) Voss], and was digested with several different restriction endonucleases. Restriction fragment length polymorphisms (RFLPs) were identified that differentiated the cpDNA of both species.

The phenology of white spruce and the spruce budworm in northern Alberta

Canadian Journal of Forest Research, 1992
Studies on the development of spruce budworm (Choristoneurafumiferana (Clem.)) on white spruce (Piceaglauca (Moench) Voss) were conducted in northern Alberta in 1969 and again in 1990. The phenology of this insect and its host were described using stochastic models.
