The Ecology of Celtis reticulata Torr. (Netleaf hackberry) in Idaho

Creator:

DeBolt, Ann M.

Abstract:

The ecology of netleaf hackberry (Celtis reticulata Torr.) is poorly known throughout its broad western range. To gain some understanding of the species' basic ecology, three components of its life history were studied. First, seed germination requirements were analyzed under laboratory conditions. Second, hackberry population dynamics were evaluated from tree...

Lichen biomonitoring in southeast Alaska and western Oregon

Creator:

Derr, Chiska C.

Abstract:

Lichen sensitivity to air quality has been recognized in Europe for over 125 years: recently Federal agencies in this country have begun using lichens as air quality bioindicators. This study presents the results of three different approaches to air quality biomonitoring using lichens: (1) a lichen community analysis, (2) an...

The association of epiphytic macrolichens and bryophytes with riparian stand types along a valley continuum, Oregon Coast Range

Creator:

Ruchty, Andrea M.

Abstract:

I surveyed epiphytic macrolichens and bryophytes in six stands in each of seven riparian stand types in the Oregon Coast Range. This study (Chapter 2) describes the association of epiphytes with stand types and the corresponding potential of forest canopy conversions to affect epiphyte communities. Species composition, diversity, and representation...
