Although originally described as a measurement of relative density in single-species, even-aged stands, it has since been generalized for use in uneven-aged stands and its use in multi-species stands is an active area of investigation. WebMar 13, 2013 · The highest fish diversity was recorded at site-III followed by site-II and site-I. The low fish diversity at site-I may be due to high altitude (1563 m) as compared to the sites II (284 m) and site-III (217 m). Hence, it may be inferred that there is inverse relationship between fish diversity and altitude of the river. examples of laser printers
