Research on protection forests designed to alleviate rockfall hazard has increased enormously over the last decade. Data are available concerning the most suitable stem spacing and density regimes in stands. The species used in protection forests can also influence enormously the effectiveness of the forest in conferring a protective role. Little information exists, however, about either the me...
Quick biodiversity studies on poorly studied taxa and areas are increasingly popular for setting conservation priorities over a wide range of spatial scales. However, the implementation of such studies is complicated by the variable extent to which the different criteria used in prioritisation are correlated to each other. Using methods of constrained ordination, we examined the specieshabitat ...
The correlation of the distribution of five subalpine and montane tree species with precipitation and temperature were modeled using GIS. The results were compared with data presented by Thompson et al. (2000). Distributions of subalpine fir (Abies concolor), Engelmann spruce (Picea engelmannii), lodgepole pine (Pinus contorta), limber pine (Pinus flexilis) and bristlecone pine (Pinus aristata)...
1. Ecosystem services (ES) lie at the core of the interactions among humans and ecosystems. Fundamental understanding of the ecological mechanisms underlying the simultaneous provision of multiple ES has been lagging behind policy and management needs and stands out as a research priority. In this paper, we focus on interactions between ES resulting from fundamental functional mechanisms. 2. Pl...
Abstract. Nowadays, the increasing pressure over water resources is reflecting on quality all globe. Not surprisingly, local, and regional governments are taking initiatives into tackling this issue. However, management of requires coordinated by stakeholders, especially in cross-border regions, to achieve efficient regulations. Then, data-sharing for monitoring fundamental stakeholder particip...
Due to the shifting global climate, frequency and severity of disturbances are increasing, inevitably causing an increase in overlapping time space. Bark beetle epidemics wildfires have historically shaped disturbance regimes Western North American forests. Their interactive effects on stand dynamics recovery inadequately studied Picea engelmannii (Engelmann spruce)-Abies lasiocarpa (subalpine ...
Diversity and species composition of endophytic fungi on leaves of 11 tree 10 species in Betulaceae were studied, with reference to climatic, tree species, and seasonal 11 variations. A total of 186 fungal isolates were obtained from 190 leaves collected in a 12 subalpine, a cool temperate, and a subtropical forest in Japan and were divided into 46 13 operational taxonomic units (OTUs) accordin...
The response of montane and subalpine hay meadow plant and arthropod communities to the application of liquid manure and aerial irrigation - two novel, rapidly spreading management practices - remains poorly understood, which hampers the formulation of best practice management recommendations for both hay production and biodiversity preservation. In these nutrient-poor mountain grasslands, a mo...
Very little is known about the changes of ground beetle assemblages in the last few decades in the Alps, and different responses to climate change of animal populations living above and below the treeline have not been estimated yet. This study focuses on an altitudinal habitat sequence from subalpine spruce forest to alpine grassland in a low disturbance area of the southeastern Dolomites in I...
This study aimed to investigate and discuss the occurrence and accumulation of mercury in the fruiting bodies of wild-growing fungi (Macromycetes) collected from montane forests in two regions of southwestern China with differences in soil geochemistry, climate and geographical conditions. Fungal mycelia in soils of the subalpine region of the Minya Konka (Gongga Mountain) in Sichuan and in the...
