Newsgroups: sci.bio,bionet.plants,bionet.population-bio Subject: Plant riparian population genetics Summary: Followup-To: Distribution: Organization: University of Washington, Seattle Keywords: Hi, I am doing research on the population genetics of black cottonwood (Populus trichocarpa) in some river valleys in the Cascade Mountains. I have searched for references on population genetics of plants (trees are preferable) in a linear spatial system (a river or stream), but have had virtually no luck in finding any. It seems to me that the genetics of such a system may be different than a typical 2-d system. I would appreciate any leads on references or studies you may know of concerning population genetics of plants in a riparian setting. Thanks John Reed (E-mail: johnreed@u.washington.edu)

Regarding populus tichocarpa, I read that this is one of the "balsam poplars", and one of the most fragrant plants to have in one's garden. Specifically, it is supposed to smell really good when the buds first open in the spring. So, I sent off for one, but when it arrived, no smell. I tried keeping it in a pot, but it died during the winter. Before I order another, was the book wrong, and this is not fragrant plant, or did it arrive after its fragrant phase, or did the nursery send me the wrong tree? Dave Daulton, Columbus, Ohio

P. trichocarpa ("black cottonwood") is a member of the section
Tacamahaca ("balsam poplars"). The yellow, sticky bud resin
is the smell of spring in the Pacific Northwest, and can be
quite strong near a big stand. P. balsamifera has a stronger,
less pleasant (to me) smell. I wouldn't recommend planting
either species near a dwelling with sewers or septic tanks,
as the Populus are notorious for clogging them with a
profusion of greedy roots.
