But biologists also warn that marine life in what is one of the world's great fishing grounds is bound to suffer.

Most of the docks are in Monmouth and Ocean counties, where biologists have warned about damages to clam beds and fish habitat from dredging and from oil and gas leaked by boats using the docks.

Some marine biologists are warning that widespread coral reef "bleaching" - a reef disorder believed to be caused by unusually warm water - is an early biological effect of global warming.

The downstream salmon, and the Indians and fishermen who depend on them, were largely forgotten in the debate, though some biologists warned that there was not enough water to satisfy all the interests.

A biologist at Cornell University, Quentin Wheeler, has warned that large numbers of insect species are becoming extinct without ever having been studied, due in part to a shortage of entomologists.

Early on, Emissary's biologists had warned that Fidelio would sicken and die if he couldn't spend several hours per week in water like that of his native sea.

Some biologists have warned that immediate steps need to be taken to preserve plant and animal species to avert a mass extinction on an epic scale within a few decades.

But biologists warn that the comparison between genes and language can be taken too far.

For some time, marine biologists at the United Nations Food and Agriculture Organization have warned that the oceans could not sustain a catch of more than 100 million tons a year.

But with an omnivorous appetite for larval or juvenile fish, shellfish and aquatic plants, marine biologists warn that this Japanese import may have begun to disrupt ecosystems in local waters.
