Table 2. Community-wide trophic metrics derived by Layman et al . (2007) for the historical (1959 – 1961) and contemporary (2003-2014) San Juan River fish community: δ13C range (CR), δ15N range (NR), centroid distance (CD), nearest neighbor distance (NND), and standard deviation nearest neighbor distance (SDNND). Values are posterior probability distribution means, percent change of those means, and probability the difference between the posterior probability distributions was greater than zero.
