Comparison of density estimates across scales
Density estimates varied substantially by scale, both in magnitude and
pattern over time (Fig. 2). The highest mean estimate was generated for
subplot-level kernel density: 5.13 bats/m2(interquartile range: 2.71-6.09), then tree-level 2-D density: 0.71
bats/m2 (0.10-0.76, subplot-level density: 0.46
bats/m2 (0.16-0.57), roost-level density: 0.38
bats/m2 (0.21-0.47), and tree-level 3-D density 0.34
bats/m3 (0.03-0.32) (means across roost sites and
time). Estimates per species were comparable, though temporal patterns
were variable between species over time (Appendix S1).
