Mutation rate

Speciation rate: Represents the speciation rate values given by the size of
each black circle for the fish community as a function of the mutation rate (
m

) and the
minimum genetic similarity value to have fertile offspring, q

, that best-fitted the
data. Each speciation rate given by the mutation rate and the genetic similarity
represents each temperature-salinity combination. There is a relationship between
the mutation rate and the minimum genetic similarity (R

of this relationship. The speciation rate fluctuates broadly among sites (4.5

B. Spatio-Temporal Patterns of Individual Rank in
Connectivity
The observed individual rank connectivity (number of prey or prey con-
sumption) curve departs significantly from the model expectations in all
environmental situations (p

).
Model expectations in the most connected individuals are one order of
magnitude less than that of the observed data in all the environmental
situations. These results remain consistently similar after accounting
for species identity or intraspecific variability in each environmental situ-
ation. The variance of the observed individual rank connectivity curve
departs significantly from the model expectations in 27 out 34 species
in all environmental situations (p
