Studies on vegetation and permafrost table depth in the zone of sporadic permafrost distribution in the Uksichan River valley (the central Kamchatka Peninsula) have provided evidence that these components of biogeocenosis are interrelated and develop coordinately. In open larch forests with green forest mosses dominating in the ground vegetation layer, the permafrost table lies approximately 60 cm below the soil surface. When the ground vegetation layer is dominated by sphagnums, the permafrost table rises to 40–20 cm. In areas with a dwarf shrub-lichen ground layer, the soil thaw depth increases. A hypothesis is proposed that cyclic successional replacement of plant communities may take place in open larch forests on permafrost soils, including four consecutive stages with dominance of green mosses, sphagnums, lichens, and dwarf shrubs. In areas disturbed by fires, pioneer moss or herbaceous communities develop in the ground layer.  相似文献

The flora of liverworts has been studied in the vicinity of the Bil’chenok glacier (the Ushkovskii volcano, Kamchatka), which is in a zone of volcanic ash fallout. Specific complexes of liverworts growing on young moraine and ash deposits have been identified. These complexes are dominated by thallose marchantioid species. Under the effect of periodic ash fallout (in the absence of glacial activity), communities are formed that contain increased proportions of xerophytes and species preferring sites with a disturbed ground vegetation cover.  相似文献

The degree of morphological differentiation of sable (Martes zibellina L.) populations was studied in different physiographic regions of the Kamchatka Peninsula and the Penzhina River basin. According to craniometric data, the sables inhabiting the hilly Western Kamchatka Plain are larger than the animals from other regions. However, the analysis of phenetic variation in craniological characters and coat color showed that the sable samples taken within the peninsula were fairly homogeneous. On this basis, all sables inhabiting the Kamchatka Peninsula may be regarded as a single population.  相似文献

International projects frequently struggle with the dilemmas of community participation, whether the community in question is the object of a development or aid intervention, or is to be persuaded to cooperate on a conservation project. This paper discusses the challenges facing interventionists and the obstacles and opportunities that local people encounter as they come into contact with exogenous conservation and development projects. The key issues presented can be summarized as legacy, legitimacy, agency and communication. We argue that project planners need to understand the history of past interventions in order to respond appropriately to local expectations. At the same time, the complexity of community leadership and representation complicates the sometimes conflicting agendas of project developers and communities. Much depends on personal relations, individual agency, and initiative. Finally, the physical means of communication—language, print and broadcast media, transport and telecommunications—are important aspects to consider when assessing the limitations to community participation. Although there have been valuable successes in international projects in Russia, as in other regions of the world, a better understanding of community participation is needed to ensure more effective and sustainable means for engaging communities in project development and implementation. This paper explores these questions through a locally-grounded analysis based on the academic research and practitioner experience of the two authors in the remote home of a World Heritage site—the Kamchatka Peninsula, in the Russian Far East.  相似文献
