Abstract

The study of relationship between absolute species abundance and body size of rodents were conducted at eight selected sites in Western Sarawak. A total of 725 individuals of rodent records have been analysed in this study. SPSS Version 21 has been used in this study in order to do the regression line and graph. The data used in this study were from two sources which were primary data and secondary data. As for primary data, the data was collected from fieldworks at Permai Rainforest Resort. Thus, the secondary data were obtained from unpublished report data at Bako National Park, Gunung Gatling National Park, Kubah National Park, Matang Wildlife Centre, Mount Serembu, Mount Singai, and Sama Jaya Nature Reserve. These data were used to represent the population ofrodents at Western Sarawak. As a result, regression graph showed positive slopes at Bako National Park, Matang Wildlife Centre, and Western Sarawak. Then, other sampling sites had shown the negative relationship between absolute species abundance and body size of rodents. These situations showed that body size was poor indicator of absolute abundance of rodents because of inconsistency of results. However, the slope of the regression lines at each sites have been tested using t-test to indicate whether it is equal or close to -0.75. The Energetic Equivalence Rule which is -0.75 proposed by Damuth (1981) was applicable for this study.
