dc.description.abstractA study consists of several biological and ecological aspects of lesser bandicoot rat, Bandicota benga/ensis in Penang. Phase one covered the population studies of Bandicota benga/ensis using mark-recapture method, necropsy and home range study while phase two covered the growth and development studies and eye lens weight as an age indicator. Population studies have been conducted at three markets (Taman Tun Saardon market, Batu Lanchang market and Sayan Lepas market). In these areas, 92%, 73% and 89% from the total captures are Bandicota bengalensis. Total population size estimation for Taman Tun Saardon market was 265.4 {with 95% confidence interval between 180.9 -424.2), 69.9 {with 95% confidence interval between 35.5 -148.9) at Satu Lanchang market and 134.7 {with 95% confidence interval between 77.8 -278.4) at Sayan Lepas market of Bandicota bengalensis. Necropsy study was conducted at Sayan Lepas market and Astaka Sukit Gedung. It objectives is to study the trend and reproductive cycles of wild Bandicota bengalensis in Penang respectively. From this study, it is concluded that female Bandicota bengalensis from both areas are able to repro~uce for the wh~le year based on corpora lutea and placental scar, that were present in most of the female rat. Home range study was conducted for seven consecutive days at Sayan Lepas Market. Radio-tracking study observed the home range area and movement pattern of Bandicota bengalensis. The home range area was calculated by 100% Minimum Convex Polygon (MCP} and 95% Harmonic Mean method. The biggest home range area was from female rat, FAdS with 160.68 m2 (100% MCP) or 217.51 m2 (95% HM) and the smallest area was from male rat MAd32 for 34m2 (100% MCP} or 59.99 m2 (95% HM). Movement was detected not far from their nests for all sampled. Study on growth and development of Jesser bandicoot rat in laboratory condition consists of observations on birth, estrus cycle, birth interval and development of Bandicota benga/ensis in control laboratory environment with food ad libitum. Based on the observation, it is concluded that birth and estrus cycle for laboratory rat in this experiment is similar to wild Bandicota bengalensis while growth and development rate exceeds the development rate for rat in the wild. Regression equation for eye lens weight for this study is Y = -1.71 + 2.18 X (R2 = 0.959, P < 0.01) for male lesser bandicoot rat andY= -1.45 + 2.03 X (R2 = 0.922, P < 0.01) for female. A clear correlation between eye lens weight and body weight and head-body length shows that eye lens weight can be used to predicts rats' maturity rate.en_US
