Counting and measuring Black-legged Kittiwake chicks on the cliffs of E. Amatuli Island in the Barrens off the tip of the Kenai Peninsula is part of the many tasks completed every summer by biologists and technicians from Alaska Maritime National...
AMNWR biologists worked over an extended period to recover the population of aleutian Cackling goose from endangered to its delisting in 2001. This album pictures the landscape, some of the hardships and activities of these hardy biologists
Jonathan Van Ballenberghe is the filmmaker for "In the Company of Moose." This film chronicles Biologist Vic Van Ballenberghe who has spent more time living with wild moose in Denali National Park, Alaska than any other researcher in the...

Phil Pister retired in February 1990 following 38 years as a fishery biologist with the California Department of Fish and Game. He studied wildlife conservation and zoology under A. Starker Leopold at the University of California (Berkeley) and...
This is the 1998 status assessment of the scaleshell mussel in the United States. It includes biological information on the species, distribution status information and detailed status figures.
A nutria is given a shot to put it to sleep while the collar is measured. Tagging the animals will help biologists to better understand the nutria as well as prevent their spreading.
Biologists prepare a tag for a nutria. The animals are trapped in order to tag them to better understand the habits of nutria and to prevent overpopulation.
The U.S. Fish and Wildlife Service does studies to find out how these animals affect habitat and other species. Biologists adjust the collar on this nutria prior to releasing him.
A sheet covers the caged nutria to keep it calm during the tail tagging. Tagging the animals will help biologists to better understand the nutria and prevent their spreading.
A collar tag to be put on a nutria. It's designed stretch so it can be put on snugly and a nutria will neither get a limb stuck inside nor have trouble breathing. Tagging the animals will help biologists to better understand the nutria's habits and...
The tagged nutria is released back into the water. Tagging the animals will help biologists to better understand the habits of nutria and prevent their spreading.
A collar is successfully attached to the nutria. Tagging the animals will help biologists to better understand the nutria and to prevent their spreading.
