Influences of the individualistic concept of vegetation on syntaxonomy, The principles of the individualistic concept, but not the above conclusions arising from them, are compatible with the integrated concept. Phytocoenoses limit the individualistic performance of species through restriction of ecological amplitudes and shifting of ecological optima (as compared with作者: 協(xié)議 時(shí)間: 2025-3-23 05:22
