The main goal of this In interpreting vegetation change, a diverse set of factors is often operative. Certain of these—initial floristic composition and the tolerance, facilitation, and inhibition models—are specifically related to the basic processes involved in vegetation or biotic change and to specific management ://

    I suggest that a discussion of this large area be added to Ch. 6 in a revised edition of Ecology, i.e., as a vegetation type â relatedâ to grasslands. In his discussion of adaptations of animals to the hot, dry desert environment, Bolen gives the reader the impression that metabolic water per se is an adaptation to this environment (p. ). F.C.

The effect of arboreal and herbaceous species growing in close proximity is further evident in the subalpine and alpine areas of the North Cascades, Washington (Bockheim, ).On Mt.

It has been suggested that the absence of trees above the treeline is caused by low temperatures that limit growth. Thus, we hypothesized that there is a critical minimum temperature (C T min) preventing xylogenesis at treeline.

We tested this hypothesis by examining weekly xylogenesis across three and four ?slug.

Conifers at the alpine timberline are exposed to drought and freeze-thaw stress during winter, which induce potentially lethal embolism.

Previous studies indicated that timberline trees survive by xylem refilling. In this study on Picea abies, refilling was monitored during winter and spring seasons and analyzed in the
