Measuring ectomycorrhizal fungal dispersal: macroecological patterns driven by microscopic propagules.

abstract：:The process of speciation remains a fundamental topic in evolutionary biology. Numerous models of speciation have been proposed and they are as diverse and colourful as the scientists who conceived them (Coyne & Orr 2004). One of the more controversial theories has been the 'stasipatric speciation' model, proposed by ...

Thus, inbreeding can be an important factor affecting the persistence of small populations. In this study, we investigated the effects of inbreeding on fitness in a small, wild populati...
