Relationship of zooplankton and environmental parameter with emphasis on copepods at Pulau Tinggi, Johor, Malaysia

There is little information on the effect of environmental parameters on the zooplankton biomass and density in the marine ecosystem. This research added on to the knowledge as results proposes statistical modeling including aspects of biomass and density to environmental parameters. The objectiv...
