Growth And Reproduction

The state of coenopopulations of vegetatively-semimobile dwarf shrubs Thymus iljinii, T. minussinensis, T. mongoliens, T. petraeus, widely distributed in steppe communities in Southern Siberia was studied. Adults of the species are a clump consisting of a primary and several partial bushes. For individuals characterized by the preservation of the main root, weak vegetative growth and reproduction, slow seizure of territory. The complex of data on organizational and population characteristics is analyzed. It is established that the real optimum state of coenopopulations of the studied species is achieved in the petrophytic variants of steppes located on the slopes of mountains. Conditions of highmountain steppe and alpine plant communities are unfavorable for Thymus.

Pollination studies in European alpine communities are few. The objective of this study was to describe the pollination ecology in two alpine plant communities at Finse, southwestern Norway. Because of late snowmelt and early winter at Finse, the time available for flowering and seed maturation is restricted. Flowering was concentrated at the beginning of the season in both communities, and large overlaps in flowering time were found for most species. In one of the communities, flowering peaks were significantly clumped, whereas in the other they were randomly distributed through the season. However, in this community, five insect-pollinated species flowered simultaneously early in the season. Diptera almost exclusively dominated the visitor assemblage. Most plant species pairs had high overlaps in flower visitor species. Species flowering simultaneously attracted the same visitor species. In one community, eight species pairs flowered sequentially and shared visitors. Visitation rates were highest at the lowest elevated site. The results are compared with those obtained in other alpine areas. It is argued that selection for an early flowering is probably stronger than selection pressures resulting from interspecific interactions. Key words: alpine, Diptera, flowering phenology, flower visitors, season length, visitation rate.
