Table 2 Estimates of coefficients of variables that suggest significant influence on avian guild species richness and abundance, standard errors (SE) and their 85% confidence intervals (CI) at the Sakaerat Environmental Research Station in 2014–2015 derived from model averaging

From: Road induced edge effects on a forest bird community in tropical Asia

  1. Edge represents distance to forest edge, D0 is stem density of vegetation with height between 0.5–3 m, C0 is percentage cover of vegetation at < 0.5 m, and C5 is percentage cover of vegetation at 5–10 m
