For both preparation and monitoring of reintroductions, increasing contacts between academic population biologists and wildlife managers is encouraged within the Survival Species Commission and the IUCN.

Anne Elizabeth Magurran is a population biologist at St. Andrews University in Scotland.

The new research, likely to shake up the contentious field of human evolution studies, was conducted by Dr. Alan R. Templeton, a population biologist at Washington University in St. Louis.

When Dale R. McCullough, a population biologist, used to take deer surveys, he would arrange scores of volunteers in a sort of skirmish line that swept across fields and marshes.

To a population biologist, says Dr. Lanyon, the idea that a casual observer could see the last of a species or even one of the last of a species is unlikely at best.

"You never can count them all," said Brian Underwood, a population biologist and technical director for the project's second phase.

Samples Are Analyzed "All great whales look alike when they're wrapped in cellophane," said Dr. Stephen R. Palumbi, a marine population biologist at the University of Hawaii in Honolulu.

I know of no reputable developmental or population biologist who doesn't accept it.

The demographer sticks to vitamin supplements, and while the evolutionary biologist calculates the compensations of celibacy, the population biologist transplants gonads, but so far only those of his laboratory mice.

"Marine preserves are considered one of our strongest tools for bringing fisheries back and protecting resources," said Dr. Steve Palumbi, a marine population biologist at Harvard University.
