Assemblage structure, species richness, abundance, and distribution of fungal fruit bodies in a seven year plot-based survey near Vienna

摘要: Almost 900 species were encountered during a seven year survey of fungal fruit bodies in 13 forests and grasslands plots measuring about 1 ha. The data comparable to those from Swiss forest plot monitored for 21 years. Species richness abundance almost linearly correlated on log/log scale. Abundance yearly frequency tightly correlated. geographic range may also be related these two parameters. Rare scored low abundance, range. About half the rare, occurred only one out major functional groups saprotrophic mycorrhizal behaved similarly over years, as study. Annual variation was high alone combined with abundances. log transformed well parameters that take abundances or frequencies into account. If other mushroom assemblages show similar regularities, it possible omit counts future surveys. composition varied strongly Many did not reach their maximum richest year. showed different same more often than expected by chance. Thus presence depended factor(s) general productivity year, years (a) aspect(s) alone. Long-term surveys are important understanding structure biodiversity.
