Conservation biology of fauna and flora in the montane-alpine zone, Central Honshu, Japan

从保护生物学的角度对具有代表性的山地和高寒生物群和生态系统进行了研究。研究了日本北阿尔卑斯国家公园6 ~ 8月融雪后高山植物的植被演替和物候变化与气温等气象因子的关系。研究了自然条件下的高寒生态系统，以及各种人为干扰对高寒生物群的影响。研究了高寒多年生草本植物越冬方式和高寒矮松（Pinus pumila）地上部物候、生理生态与环境变化的关系。研究了日本山毛榉（Fagus crenata）和七叶树（Aesculus turbinata）在立山海拔900 ~ 1400米的山地区的更新过程和生态生理。2 .对日本山毛榉的生长活力和空气污染对其生理的影响进行了为期17年的监测，其中包括1993年和1994年两年的研究期。在山地和高寒地区研究了日本雪猴（Capricornis crispus）、日本猕猴（Macaca fuscata）等多种小型哺乳动物的行为和生活史。对高山雷鸟（Lagopus mutus）的行为和生活史参数进行了批判性研究。

The representative montane as well as alpine biota and ecosystems were studied from the standpoints of conservation biology.1.Vegetational succession and phenology of alpine plants after snowmelt during June to August were studied in connection with the changes in temperature and other meteorological factors in the Japan North Alps National Park. Not only alpine ecosystems under natural conditions but also effects of various human disturbances to alpine biota were critically surveyed. Wintering froms of alpine perennial herbs and shoot phenology and eco-physiology of alpine dwart pine (Pinus pumila) in relation to changes in environmental regimes were studied.2.Regeneration process and eco-physiology of Japanese beech (Fagus crenata) and horse chestnut (Aesculus turbinata) were studied in the montane zone, 900-1,400m above sea level, on Tateyama. The results of monitoring as to the vigor of Japanese beech trees, and physiological effects due to air pollution have been studied in the permanent plots for last 17 years, including the two years'study period (1993 and 1994).3.Behaviors and life histories of various mammals, such as Japanese serow (Capricornis crispus), Japanese monkey (Macaca fuscata), and several other small mammal species were studied in montane as well as alpine zones. Bahaviors and life history parameters have been critically studied on alpine ptarmigan (Lagopus mutus).
