- ... Pinus aristata Engelm., Rocky Mountain bristlecone pine, has a narrow core geographic and elevational distribution, occurs in disjunct populations, and is threatened by rapid climate change, white pine blister rust, and bark beetles. Knowledge of genetic diversity and population structure will help guide gene conservation strategies for this species. Sixteen sites across four mountain ranges in th ...

- ... False rings are intra-annual bands of wood darker than the adjacent wood. They have been reported for several species of Pinus, although not previously for white pine (Pinus strobus L.). In southwestern Quebec, false rings were found to be very common among white pine, an indication that the species is sensitive to water stress in this region. False rings were analyzed on 110 trees from 12 mature ...
