- This study was conducted to provide basic information for
environmental monitoring and developing strategies for conservation of
biological diversity in ecosystems by comparing soil-dwelling spider
communities among differently stressed areas. Study sites were located
in Paltan-myun, Hwaseong city, Kyunggi-do, Korea. Three sites were
selected after consideration of waterway, traffic, and land use, etc. Four
habitat types (levee, upland dike, hillock, and stream ridge), which
were adjacent, were selected within each site. Study sites were mainly agricultural (paddy field and upland) and forest area (site 1), industrial
area (site 2), and residential area (site 3).
Pitfall trap samplings were carried out 38 times from November
2000 to October 2002. A total of 15,182 soil-dwelling spiders were
collected and total 173 species 109 genera belonging to 29 families of spiders were identified.
Among three sites, the site 2 had the least number of individuals and
species. Among the same habitat types of three sites, the number of
individuals of the levee and the stream ridge had the highest in the site
3. That of the upland dike and the hillock was the highest in the site 2.
The number of species of the site 2 was the least in three habitat types
except the levee. Among habitat types within each site, population sizes
were different. Number of species was high in the hillock and low in
the stream ridge.
Seasonal occurrence of soil dwelling spider populations showed a
similar pattern among sites and reached peak in August. Population size
was higher in the site 1 than in other sites in 2001. It was higher in the
site 3 in 2002 more. Among the same habitat types of three sites, more
similar seasonal fluctuation patterns were shown in the hillock than in
other types of habitat. Among habitat types within each site, seasonal
fluctuation patterns were similar in all habitat types. In the site 1 and
site 3, population size was higher in the hillock than in other habitat
types. In site 2, it was higher in the levee and the stream ridge than in
other habitat types...
