A Preliminary Study on the Relationship between Arthropod Diversity and Vegetation Diversity in Four Contrasting Ecosystems in Hanthana Mountain Range of Sri Lanka, during the Post-Monsoon Dry Season

Table 1

Variation of arthropod and vegetation diversity in the ecosystems selected for the study.

Ecosystem	Arthropods			Vegetation
	Shannon–Wiener index	Species richness	Evenness	Shannon–Wiener index	Species richness	Evenness
Aquatic	2.641^a	16.33^a	0.972^a	1.810^b	22.33^a	0.601^b
Broad-leaved	2.444^a	12.67^ab	0.983^a	1.871^b	15.00^a	0.698^b
Pinus	1.411^b	5.00^c	0.974^a	0.879^c	21.67^a	0.286^c
Pinus enriched	1.350^b	9.67^bc	0.635^b	2.614^a	19.67^a	0.884^a
CV (%)	26.99	43.90	8.47	22.38	32.68	18.48
p > F	0.057	0.0005	0.0032	0.011	ns	0.0038

Along each column, means with the same letter are not significantly different at  = 0.1 based on least significant difference. ns–non-significant at  = 0.05. CV–coefficient of variation.
