Abstract Recently, a dwarf bamboo species, Sasa kurilensis ; Poaceae, has invaded into alpine snow‐meadows in the wilderness area of Taisetsu Mountains, northern Japan. This species wide distribution range from lowland to sites snowy regions. Because formation dense evergreen culms and an extensive rhizome system, other plants are excluded following invasion by this bamboo, resulting low diversity. Dwarf originally inhabited leeward slopes pine ( Pinus pumila ) clumps During last 32 years,...

Abstract Alpine landscapes are projected to be degraded under climate change, which would threaten their benefits society. Previous studies, however, have been limited aesthetic and it remains unclear how much the change affect human welfare. To address this issue gain insights into adaptation policies, we conducted a choice experiment survey using digitally manipulated images based on scenarios natural scientific knowledge in mountainous national park Japan. We uncovered that visitors...

Abstract Question Alpine plant communities are often distributed as a mosaic reflecting micro‐scale heterogeneity of environmental conditions, indicating the importance diverse habitats in maintaining species diversity alpine ecosystems. Because snow‐meadow vegetation is particularly sensitive to climate change, composition and community structure may have changed over last few decades response global warming. The aim present study quantify changes 40 years. Location Taisetsu Mountains,...

Abstract Robust estimates of demographic parameters are critical for effective wildlife conservation and management but difficult to obtain elusive species. We estimated the breeding adult population sizes, as well minimum size, in a high‐density brown bear on Shiretoko Peninsula, Hokkaido, Japan, using DNA‐based pedigree reconstruction. A total 1288 individuals, collected around Peninsula between 1998 2020, were genotyped at 21 microsatellite loci. Among them, 499 individuals identified by...

The vulnerability of alpine ecosystems to climate change, as pointed out by the Intergovernmental Panel on Climate Change (IPCC), and necessity monitor zones have been recognized globally. Japanese zone is characterized extreme snowfall, snowmelt time a key factor in growth vegetation. Therefore, 2011, National Institute for Environmental Studies (NIES), Japan, initiated long-term monitoring using automated digital time-lapse cameras. Twenty-nine sites are currently operation. In this study,...

Abstract Question Alpine vegetation is sensitive to climate change, with shifts in species ranges, changes community composition, and an upward shift the forest limit over decades. Under habitats suitable for alpine will progressively decrease scale, making their protection conservation particularly important. In Taisetsu Mountains of Japan, has changed remarkably during last decade. The aim this study was estimate distribution subalpine types (snowbeds, shrubs, heathland/fellfield)...
