Publikováno v: Applied and Environmental Microbiology
Applied and Environmental Microbiology, American Society for Microbiology, 2001, 67 (5), pp.2255-2262. ⟨10.1128/AEM.67.5.2255-2262.2001⟩

The similarities and differences in the structures of thenifHgene pools of six different soils (Montrond, LCSA-p, Vernon, Dombes, LCSA-c, and Thysse Kaymor) and five soil fractions extracted from LCSA-c were studied. Bacterial DNA was directly extrac

Mycological Research, Elsevier, 2000, 104 (5), pp.587-594. ⟨10.1017/S0953756299001744⟩

An investigation was conducted into whether fungal dynamics are determined by the balance between colonization and fructification, both of which are controlled by climatic factors, particularly rainfall. The distribution of Lophodermium pinastri on P

Host and geographical distribution of Verticicladium trifidum, Thysanophora penicillioides, and similar fungi on decaying coniferous needles

Autor: François Gourbière, A. van Maanen

Publikováno v: Canadian Journal of Botany. 75:699-710

Dematious hyphomycetes such as Verticicladium trifidum and Thysanophora penicillioides are examples of equivalent species occupying the same ecological niche in different fungal successions. These two species fructify through the stomata of coniferou
