“…Increased species richness has been associated with both low (Setty, 1976, Schafer et al, 1991, 1995, Armynot du Châtelet et al, 2004 and high (Bandy et al, 1964a, 1964b, 1965, Cearreta, 1988, Debenay et al, 2001 the deepest parts of the lagoon, is lower than for assemblage 2. Because Smiths Lake is considered predominately oligotrophic, (Smith and Heggie, 2003) overall species richness should be higher than comparable systems where organic matter is high.…”
