Abstract: 

"From single molecules to migrating storks".  
We study a technique that allows an experimentalist to quantify separately the degree, to which an observed anomalous diffusion in a time series occurs due to: 
i. non-stationarity (the ``Moses effect"), ii. extreme rare events (``Noah effect") or iii. temporal correlations (``Joseph effect"). 
This decomposition method offers a way to obtain a better understanding about the underlying dynamics of the system, without making prior assumptions on the model that describes it. 
It can also, to some extent, eliminate non-fitting models that one might suggest for this purpose. We demonstrate the applicability of this approach by analyzing data from several microbiological and ecological experiments. 
The hope is to promote its use for more systems in the future, and its further investigation.
