Functional
traits
We evaluated differences in species richness and number of individuals
of each functional trait between plots near roads, and plots further
from roads. For these data, we used generalized linear models (Glm),
Poisson family, with a logarithmic link function. When residual
deviations were greater than the residual degrees of freedom, the
standard errors were corrected using a Quasi-Poisson. We assessed
significance using the Chi-squared test. All analyses were performed in
R statistical environment (R Development Core Team, 2015).
