The Model of Odonate Diversity Relationship with Environmental Factors Based on Path Analysis
Abstract: This study aims to
analyze and describe the relationship between altitude, aerial variables
(temperature, light intensity, humidity), water qualities (water temperature,
pH, BOD, COD, DO, TOM, and water velocity), and vegetation with the diversity
of Odonate assemblages. Odonate samplings were conducted at six survey sites
based on altitude and vegetation characteristics. Measurement of altitude,
aerial variables, water qualities and vegetation characteristics were replicate
in the first day and third day. Analysis of correlations of all environmental factors
with the odonate diversity was done through structural equation model using
Partial Least Squares (PLS), Open source Smart Software and Microsoft Excel.
The aerial variables and water qualities affected indirectly on odonate
diversity. The aerial variables directly or with interaction to other factor
affected the water qualities and vegetation characteristics. The vegetation
characteristics directly influenced to odonate diversity. Water flow affected
water quality, light intensity affected the aerial, while morning period
observation affected the odonate diversity. Predictive relevance (Q2) for a
model designed amounted to 99.95%, while the rest of 0.05% are explained by
other variables.
