A molecular study of microbe transfer between distant environments.

<h4>Background</h4>Environments and their organic content are generally not static and isolated, but in a constant state of exchange and interaction with each other. Through physical or biological processes, organisms, especially microbes, may be transferred between environments whose ch...

We also suggest a bias in direction from soil to sea, which is consistent with the cycles of planetary wind and water.<h4>Conclusions</h4>Our findings support the Baas-Becking hypothesis formulated in 1934, which states that due to dispersion and population sizes, microbes are likely to be found in widely disparate environments.
