Results of Elements of Metacommunity Structure analysis.

<p>Results of Elements of Metacommunity Structure analysis testing for coherence, species range turnover and boundary clumping in 168 low-mountain streams in central Germany categorised into all sites (N = 168), headwaters (N = 48), mid-sized (N = 69) and large rivers (N = 51). <i>Abs</i> = number of embedded absences, <i>Re</i> = number of replacements, <i>MI</i> = Morista’s Index, SD = standard deviation. Both primary and secondary axes of organization are given. Mean and SD values are those calculated from the 1000 generated null matrices.</p><p>Results of Elements of Metacommunity Structure analysis.</p>
