| Abstract |
|
Population density and spatial distribution pattern of Sacalia quadriocellata was studied by regular sampling conducted from March to July of 2004 in Limu Mountain,Hainan Island.Four indices,Cassie index,David Moore index,Morisita index,and Lloyd index,were used to evaluate the aggregative degree of S.quadriocellata.Populations of S.quadriocellata are scatteredly found at elevations between 170-470 m with a discontinuous pattern.The relative population density is 0.011-0.050 ind./cage-day.The populations are spatially aggregated in their distribution range.Human disturbance and uneven distribution of the natural resources may affect the population density and spatial distribution pattern.
