Figure 1. Map of sample
sites on the Vermilion and North Fork Rivers . Circles indicate sites on
the Vermilion River, triangles represent site on the North Fork River
and the red bars indicate the dam removal sites. DWN : Downriver of Dam,
IMP: Impounded, ROR: Run of River.
Figure 2. Response of
environmental parameters to river location and dam removal. Grey
indicate pre-removal values and white indicate post-removal values.
Values plotted are means +/- standard error. Refer to Figure 1 for
explanation of location abbreviations.
Figure 3. Response of QHEI
to river location and dam removal of each habitat on both rivers. Grey
markers are average pre-removal values and white markers are average
post-removal, +/- standard error. Dashed lines are labeled to correspond
score to the health of the river. Refer to Figure 1 for explanation of
location abbreviations.
Figure 4. Response of Index
of Biotic Integrity (IBI) to river location and dam removal of each
habitat on both rivers. Grey markers are average pre-removal values and
white markers are average post-removal, +/- standard error. Dashed lines
are labeled to correspond score to the health of the river. Refer to
Figure 1 for explanation of location abbreviations.
Figure 5. Response of total
fish abundances to dam removal in each river location. Grey bars
indicate pre-removal values and white bars indicate post-removal values.
Values plotted are means +/- standard error. Refer to Figure 1 for
explanation of location abbreviations.
Figure 6. Non-metric
multidimensional scaling (NMDS) ordination displaying impacts of dam
removal on habitat and reproductive guild abundances and habitat
metrics. Guilds are displayed as black vectors and QHEI and IBI are
displayed as a grey vectors. Refer to Figure 1 for explanation of
location abbreviations.
Figure 7. Response of guild
diversity to dam removal. Grey bars indicate pre-removal values and
white bars indicate post-removal values. Values plotted are means +/-
standard error. Refer to Figure 1 for explanation of location
abbreviations.
