Effect of spatial structure to mosaic habitats could be interpretated in terms of landscape ecology. Various topics of conservation biology and resource management are relevant to land use which shows the significance of landscape ecology principles. Only very few investigations have been performed in connection with habitat resources and landscape structure both in micro-landscape scale and landscape scale that effecting the “species”. The present study deals with the effect of factors both in landscape scale and micro-landscape on distribution of Acraea issoria in Chitou, and intends to predict the percentage and density of Acraea issoria in the patches as well. Topics of the present study includes:
1.To discuss the factors effecting the distribution of Acraea issoria in the patches within landscape scale.
2.To discuss the factors effecting Acraea issoria density in the patches within landscape scale.
3.To correlate the distribution of Acraea issoria with the plant community inside the patches within micro-landscape scale.
The result of present study shows that we can compute distribution of Acraea issoria in landscape and predict the percentage and density of Acraea issoria in the patches within landscape scale by using regression models. Within the micro-landscape, distribution of Acraea issoria could be accurately described inside the patches by correlating the distribution of Acraea issoria with the plant community. In terms of landscape scale (both macro and micro) the distribution of Acraea issoria could be better understood, including factors of species distribution, habitat condition and Acraea issoria growth with plant community. In conclusion, the present study is a case study example in landscape ecology and population ecology both in macro scale and micro scale.
