  1. Physiological and stoichiometry study on foliar nutrients and defensive characteristics of representative deciduous broad-leaved tree species in northern Japan under environmental changes [an abstract of entire text]

    石, 聡
    In chapter 1, I made a general introduction about environmental changes, tree species as well as general description about nutrients stoichiometry and defense characteristics. In natural forests, uptake and release are two important factors due to representative of primary flux in ecosystem. Nutrients are absorbed from soil and being used for plants growth, physiological responses or being returned via decomposition through litter fall and being available again for next nutrient cycling. Consequently, stoichiometry is dependent on the balance among uptake, amount of retranslocation rate and loss of the processes. At the same time, plant defense is a vital mechanism for...

  2. 北海道の森林における樹洞木と立枯れ木の動態及び機能に関する研究

    小野寺, 賢介
    Wise use of multiple ecosystem functions is critical to the sustainable development of human society. As a result of the continued increase in demand for timber production, declines in forest biodiversity have become serious problems worldwide. Cavity trees and snags provide essential habitat for many species, and are considered important elements in forest biodiversity conservation. The objectives of this study were to develop cavity and snag management plans, integrating biodiversity conservation with timber production in managed forests. Various species, from small-bodied rodents to large-bodied raptors, use cavities as their essential habitat (e.g. breeding and foraging sites). Because the size of...
