Abstract
Ant species distributed over a wide
range of habitats and played many different
ecological function roles in varied
ecosystems. Therefore, ant species
assemblages have been used as biological
indicators of environmental condition and
management practices in many different
ecosystems. We hypothesize that
assemblages of ant species in different
ecosystems of our study area will show
significant differences depending on
environmental factors, soil condition, human
perturbations, and management practices.
In addition, they are capable of providing an
assessment over a wide range of stresses.
So, they may have potential as a biological
indicator of biodiversity condition in many
different ecosystems in our study area. To
assess this hypothesis, we try to find the
group of ants that are sensitive to provide
early warning for changes of biodiversity in
the ecosystem. Associations between ant
species, and environmental conditions and
vegetative structure will be analyzed first.
Trophic webs in different ecosystems will be
constructed then, to clarify plant-ant-soil
arthropod interrelationship.
One high-latitude area was chosen as
research area. In this area, ant fauna will be
surveyed every month in various ecosystems
of grassland, secondary forest, virgin forest,
and stop-cultivated land. From the
2
comparison of ant composition in grassland,
virgin forest and secondary forest, we can
understand the change patterns of
biodiversity in different ecosystems.
However, the biodiversity changes in
succession process can be revealed by the
comparison between ant composition in
secondary and virgin forest. By comparing
the ant fauna among virgin forest and
grassland, we will understand the
interference of human activity on the
biodiversity. In addition, quantification and
evaluation of human manipulation on the
impact of biodiversity will also obtained by
comparing the ant fauna among
stop-cultivated land, secondary forest and
virgin forest. This result can serve as a
reference for the future work on the
maintenance and recovery of biodiversity.
In this study, we unveil the ant fauna,
the population fluctuation of the dominant
species, the changes of spatial distribution
and biodiversity. In addition, we will
analyze the relationships among soil types,
environmental factors and ant community in
various ecosystems. Furthermore, we can
evaluated the suitability of using ant as a
biological indicator of ecosystem quality and
conservation managing tactics judging from
the relationships of ant community's time and
spatial distribution and plant community and
established from various ecosystems,
succession stages, managing tactics or human
interference.
