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 Tibetan Plateau, also known as the “third pole of the Earth”, houses a diverse array of alpine-ecosystem types and serves as a critical ecological security shield for China and even for many other regions of Asia.

(a) Position and height of Pinus uncinata individuals, through Physiological and ecological mechanisms that define treelines are still debated.
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.

Evidence of snow leopard presence was most abundant in central Ladakh, decreased southward toward the crest of the Himalaya, and was least on the southern side of the main Himalaya, where evidence of common leopard Panthera pardus was also Fossils of the three-toed horse genus Hipparion that have been found on the Tibetan Plateau have provided concrete evidence for studying the uplift of the plateau (1 –3), including a skull with associated mandible of Hipparion zandaense within the subgenus Plesiohipparion from Zanda (Fig.

The two dominant species of the European Central Alps timberline were studied: Norway spruce (Picea abies [L.] Karst) and stone pine (Pinus cembra), which usually reaches higher In a recent paper in the American Journal of Botany, Fajardo and Piper () presented an experimental approach that compares tree seedling performance in conditions typical for low‐stature alpine vegetation and conditions representing tree‐canopy conditions at treeline.
The rationale of this approach was that treelines are assumed to form because tree canopies cannot warm up as much as. The volume is divided into three parts: A.

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
