| dc.description.abstract | Research entitled Diversity of Macrozoobentos in Silalahi Village, District of
Dairi, Toba Lake Waterway has been done to analyze the diversity of
macrozoobentos and the relationship between the water physico-chemical factors
with diversity of macrozoobentos in Silalahi Village, District of Dairi, Toba Lake
Waterway. This study used Purposive Sampling method in five different locations
based on human activities at each study site. The research showed that there were
17 genera of macrozoobentos included into two phyla, 4 classes, 6 orders and 12
families. The highest density was showed from genus Thiara with value of 30.86
ind /m2
which were found at station 1 and the lowest density was showed from
genus Notonecta with value of 2.47 ind / m2
. The highest Diversity index (H ')
was from station 3 with value of 2.58 while the lowest was from station 5 with
value of 1.92. Uniformity index value (E) ranged from 0.92 to 0.95. Results of
correlation analysis shows the temperature had very strong influence on diversity
index (H ') of macrozoobentos. | en_US |
