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.
