Abstract
Changes in community structure and
functional organization of macroinvertebrates
were investigated to examine how riparian
vegetation and land use influence
macroinvertebrate distribution at 7 sites
along the Hapen Creek, which flows through
Fushan Forest in northern Taiwan. A
modified Surber sampler (area = 50 x 50 cm2;
mesh size = 250μm) were used to collect
macroinvertebrates. A total of 81 taxa were
collected during the sampling period. The
taxonomic richness of Ephemeroptera and
Diptera were most diverse and Trichoptera
was the third diverse group. In general, the
values of taxonomic richness decreased
downstream. Baetids were the most
numerous taxon and accounted for more than
73% of total individuals at site 6 which
riparian vegetation was dominated by
Miscanthus spp. Simuliids were the second
numerous taxon and accounted for 13-26% of
total individuals at site 3, 4, and 5 which
were located at downstream of an
impoundment. These three sites were also
possessed the highest number of individuals.
Among the 7 sampling sites,
collector-gatherers and grazers were the most
dominant functional feeding groups.
Specially, site 6 was dominated by grazers
and site 3, 4, and 5 by collector-filterers.
These results suggested that riparian
vegetation and land use influence
macroinvertebrate community structure and
functional organization. This may be due to
3
changes in energy and food sources of
macroinvertebrates.
