Abstract

This study estimated the mound litter biomass and the nutrient content of mound litter in the two study plots in Durokoppin Nature Reserve, Western Australia between 2004 and 2005. There were no significant differences in biomass of litter in individual mounds between the two study plots. Seven components of litter were found in the mounds. The nutrient concentrations were higher in the woodland than in the shrubland plot, although the differences were not statistically tested, and the total amount of each nutrient measured was generally greater in the woodland than in the shrubland plot. The aforementioned results show that D. tamminensis harvests various plant material according to biomass availability. The role of this termite takes on particular importance in view of the fact that Western Australian soils are notoriously impoverished in nutrients.

본 연구는 서부 호주의 Durokoppin 자연 보호 구역에 서식하고 있는 흰개미에 의해 수확되어 개미집에 저장되어 있는 식물유체와 영양물질 함량을 조사하기 위해 수행되었다. 개미집에 저장된 식물유체의 경우 두 조사지역간의 유의적 차이는 없었으며, 개미집에 저장된 식물유체를 분류한 결과 잎과 가지 등 7가지 종류의 식물 유체로 확인되었다. 개미집 내 저장된 식물유체의 영양물질 함량은 유의적 차이는 없었지만 shrubland 보다 Woodland가 높았으며, 영양물질 총량 역시 shrubland보다 Woodland가 많았다. 연구결과를 종합해 보면 흰개미는 조사지역에서 다양한 종류의 식물유체를 수확하여 이용하고 있으며, 조사지역내 토양 유기물 함량이 적은 점을 고려할 때 생태계 영양물질 순환에 있어서 중요한 역할을 하고 있는 것으로 사료된다.
