온도 구배에 따라 3가지 유형의 다양성 패턴(증가형, 종형, 감소형)이 보고되었다. 아직까지 이 세 가지 다양성패턴이 나타나는 원인을 종합적으로 설명하는 이론은 없었으나, 최근 권태성은 진화기반 다양성 모형으로 그것을설명하였다. 이 모형은 분류군이 최초에 진화한 지역의 온도조건에 따라 다양한 유형의 다양성 패턴이 나타날것으로 예측하였다. 열대기후에서 진화한 분류군은 우리나라에서 증가형의 다양성 패턴이, 온대기후에서 진화한분류군은 종형이나 감소형 패턴이 나타날 것을 예측한 바 있다. 이 가설을 검정하기 위해 연평균 기온이 7.4℃에서12℃ 의 온도구배에 따라 6개소 조사지(활엽수림)를 선정하여 함정트랩에서 채집한 노린재목 곤충(진딧물 제외)의다양성(종수)를 비교하였다. 노린재의 다양성은 기온이 높을수록 낮아지는 감소형 패턴이었다.
Disassembly or assembly of an ant community in a temperate forest
권태성 국립중앙과학관 2015 Journal of Asia-Pacific Biodiversity Vol.8 No.2
Because the occurrence of living organisms is limited by competition, it is normal for organisms to follow the assembly rule in which similar species do not co-occur. In order to test whether ants within a forest follow the assembly rule, ant data surveyed for 10 years in an old temperate forest were analyzed. In most cases, co-occurrence among ant species was not different to random co-occurrence, and less cooccurrence was found only in some years, indicating ephemeral influence of competition. This finding was confirmed in the correlation analysis using data of abundance. Therefore, ants living together in a small area within a forest did not follow the assembly rule.
Distribution patterns of Monochamus alternatus and M. saltuarius(Coleoptera: Cerambycidae) in Korea

Distribution patterns of two pine sawyer species (Monochamus alternatus which is the mainvector insect and M. saltuarius which is the potential insect vector of the pine wood nematode) wereinvestigated in Korea. The data were collected at 89 study sites which were chosen to cover the wholestands to be egg-laid by the pine sawyers. Emergence of the betles from the dead pine tres was checkedfrom early April to late July. M. saltuarius was the most abundant in the mid to northern areas of SouthKorea, whereas M. alternatus in Jeju-do, southernmost island of Korea. Considering temperature distributionpatterns in areas where the two species occur, their thermal distribution boundary may be formed around13.2oC of annual mean temperature.

Prediction of abundance of ants according to climate change scenarios RCP 4.5 and 8.5 in South Korea
권태성,이철민 국립중앙과학관 2015 Journal of Asia-Pacific Biodiversity Vol.8 No.1
In order to identify change of ant distribution expected due to climate change in South Korea, data on ants collected from 344 forest sites were used to predict change of abundance of ant species. In distribution of abundance along temperature gradient, 16 species displayed the patterns expected from normal distribution. For these species, abundance in temperature zones was used to link with temperature changes and predict the abundance. Temperature changes were based on Representative Concentration Pathways (RCP) 4.5 and 8.5, and the national average and distribution of abundance during the two periods from 2011 to 2015 and from 2056 to 2065 were predicted. The rate of change of ant abundance and the average temperature of the collection sites showed a clearly positive relationship. Based on these results, qualitative prediction (increase or decrease) was conducted for species with ≥ 1% occurrence. The results showed that eight species would increase and 29 decrease, so the number of the decrease-expected species is three times more than that of the increase-expected species.
Change of ant fauna in the Gwangneung Long-Term Ecological Research site in South Korea
권태성 국립중앙과학관 2015 Journal of Asia-Pacific Biodiversity Vol.8 No.3
Ant surveys were carried out in seven different years from 2002 to 2012 at the Gwangneung Long-Term Ecological Research site in South Korea to identify changes of ant communities using pitfall traps. Principal component analysis was used for analysis of communities. Species diversity of ant community decreased and species composition changed in 2004, when forest species decreased but open habitat species increased. The diversity was restored in 2005, but community structure did not return to the predisturbance state. The first numerically dominant species was changed from Aphaenogaster japonica to Formica japonica since 2004. The disturbance value of ant communities recognized a disturbance in 2003. Ant species foraging on vegetation were increased in abundance and were changed in occurrence each year since 2005, indicating that an increase of understory vegetation after forest disturbance would influence ant community composition.
