Nutrient composition and physicochemical characteristics in the destination sites of migratory water birds: a case study at the selected locations of seashores and lakes in southern India

<p>The biodiversity in aquatic systems are indirectly controlled by their nutrient dynamics. The abundance of phytoplanktons and zooplanktons depends on the availability of nutrients such as nitrates, phosphates and silicates since these are the building blocks for their further growth. The ph...

The abundance of phytoplanktons and zooplanktons depends on the availability of nutrients such as nitrates, phosphates and silicates since these are the building blocks for their further growth.
