Tab. 2 in Seasonal variation in fish trophic networks in two clear-water streams in the Central Llanos region, Venezuela

Tab. 2. Mean dietary overlap among fish species in two Venezuelan Llanos streams (Charcote and Charcotico) collected during four survey periods. Values in parentheses are standard deviations (SD). Pseudo-communities> Real communities indicates the proportion of pseudocommunities with mean overlap values higher than the mean value recorded for the community (%). P values were based on comparison with null model calculations (pseudo-communities), and values lower than 0.05 indicate significant resource segregation among species. January was the low-water period, September was near the peak of the annual flood pulse, and during November and December floodwaters were gradually receding.
