The odd fraction [c] in variation partitioning: a case study on fine scale variation in oak forest herb layer

Popis výsledku v původním jazyce

After the introduction of Hubbell?s neutral theory of biodiversity, partitioning of ecological variation into spatial and environmental components has become a common practice in many ecological studies. Along with the rediscovered dispersal issues, popularization of the PCNM method as a spatial modelling tool has undoubtedly contributed a great deal to this trend. The variation partitioning is believed to give us an insight into mechanisms structuring species distributions, with environmental control (i.e. niche processes) one the one side and dispersal limitation (i.e. neutral processes) on the other. In this line of reasoning, the proportion of so called pure spatial variation (fraction [c]) is usually related to the importance of dispersal processes whereas the environmental fraction ([a + b]) is ascribed to niche filtering. It is then perfectly justified to only collect and compare percentages across communities.
