Evidence for higher biological productivity comes in the form of biogenic Barium.

Healthy estuaries can have high rates of biological productivity.

These factors are critical to a lake's biological productivity.

It provides for exchange of data on currents, biological productivity and other ocean research.

Large fluctuations in water level due to power generation affect the recreational opportunities and biological productivity of the lake.

Because of these cracks in the ice there is more biological productivity in the ocean.

In addition, their biological productivity - the growth of body mass - was discovered to be higher than any other animal.

A eutrophic body of water, commonly a lake or pond, has high biological productivity.

The other major area of research is focusing in on the biological productivity in this region.

There the juveniles can take advantage of the high biological productivity and maximize their growth rate.
