A population of Trigoniulus corallinus (Gervis) in an open land rich in organic matter is studied for a year. Population density and biomass ranged from 2.13 to 56.31per m2 and 1026.38 to 8494.38 per m2 respectively. Various indices showed that population of T. corallinus is aggregated in distribution in the peak period of their abundance and this is due to patchy distribution of food, soil moisture and sexual attraction. Monthly age structure showed adult and late stadia are abundant in June, October and November while August population covered all the stadia. In the developmental stages, length and width progression factor of T. corallinus ranged from 1.11 to 1.98 (mean 1.43) and 1.10 to 1.56 (mean 1.31) respectively. Weight progression factor in female is higher compared to that of male and this may due to more accumulation of egg forming tissue in female. Population density and biomass is significantly correlated with minimum temperature and rainfall.

Trigoniulus Corallinus（Gervais）（Diplopoda：Spirobolida）的种群生态学。

研究了在一个富含有机质的空旷土地上的三角龙（Gervis）的种群。人口密度和生物量分别为2.13至56.31 / m2和1026.38至8494.38 / m2。各种指数表明，珊瑚礁的种群在其丰度的高峰期聚集分布，这是由于食物，土壤水分和性吸引的分布不均。月度年龄结构表明，成年和晚期体育场在6月，10月和11月丰富，而8月人口覆盖了所有体育场。在发育阶段，T.coralinus的长度和宽度进展因子分别为1.11至1.98（平均1.43）和1.10至1.56（平均1.31）。与男性相比，女性的体重增长因子更高，这可能是由于女性卵子形成组织的积累更多。人口密度和生物量与最低温度和降雨量显着相关。
