Abstract
We have collected 5252 individuals from
forest canopies in Fu-shan in February and
April. These specimen belong to order
Thysanura, Collembola, Orthoptera,
Thysanoptera, Dermaptera, Hemiptera,
Neuroptera, Hymenoptera, Homoptera,
Coleoptera, Lepidoptera, Diptera, and other
fewer invertebrates. Homoptera is the highest
in abundance. About 60 % of specimens
were Homoptera in samples collected in
February. This result shows the canopy of
Fu-shan forest should have been disturbed.
Using numbers of arthropods per gram leaf
dry weight as a standardized abundance
index, the phenology of plants was also
having some influence on the results of
arthropod collections. Although the number
of specimens declined, the index slightly
increased in April. Different area would
show different changes in arthropod
abundance. Arthropod abundance changes
dramatically between months in Special-used
Botanical Garden. Besides, the difference of
abundance index of arthropods in gap sites is
insignificant, but decreased significantly in
non-gap sites. Arthropod abundance on
Litsea acuminata and Blastus cochichinensis
were higher than other tree species, and the
difference between replicates were also
higher on other tree species. We expect to
find distinct arthropod assemblages among
different host plant species and disturbance
levels. Besides, early successional stage at
each site could show an arthropod dominance
hierarchy that is distinct from that of late
successional stage at each site, e.g.,
dominance by sap-sucking arthropods on
early successional stage vs. dominance by
folivores on late successional stage.
