ests, fire chronology, and the role of American Indians in vegetation patterns. He has devoted considerable effort to the establishment and study of Research Natural Areas leading to an award from
USDA Forest Service Chief Dale Robertson for 20
years of work in this area.
James R. Duncan obtained his B.S. Honors in Zoology from the University of Guelph in 1982, a
B.Ed. from Queen's University in 1983, his M.Sc.
from McGill University in 1985 for research on inbreeding and mate choice in American kestrels, and
his Ph.D. in 1992 under Robert W. Nero studying
great gray owls. He has authored and coauthored
numerous publications on raptors and owls, including two species accounts in the A.O.U. Birds of North
America series. Jim is currently writing a monograph
on great gray owl ecology. Since March 1992, Jim
has held the position of Coordinator and Research
Zoologist with the Saskatchewan Conservation Data
Centre, The Nature Conservancy. Meanwhile, he and
his wife, Patricia (also a zoologist), have continued
their studies on northern forest owl ecology in southeastern Manitoba and adjacent Minnesota. James
currently monitors: small mammal population fluctuations, use of 140 potential great gray owl nests
and boreal owl nest boxes, and winter owl irruptions and invasions. For four years, Jim has coordinated an annual nocturnal owl survey involving
over 100 volunteers and covering over 600 kilometers of survey routes throughout Manitoba and adjacent Minnesota. Jim, Patricia, and their young son,
Connor, welcome inquiries into their research and
extend an invitation to those interested in visiting
their study area.
Gregory D. Hayward received his master's and
Ph.D. in wildlife ecology from the University of
Idaho in 1983 and 1987. His graduate research first
examined resource partitioning among forest owls
in a wilderness setting and then focused on habitat
use by boreal owls. After completing his graduate
work Greg served as Visiting Assistant Professor at
the University of Idaho prior to working with John
Wiens at Colorado State University examining the
effects of the Exxon Valdez oil spill on seabird populations and communities. His current research includes investigations of boreal owl demography and
habitat use, small mammal habitat use, and arboreal lichen ecology. Greg currently holds a temporary position with the Rocky Mountain Forest and
Range Experiment Station, Laramie, Wyoming.
Patricia H. Hayward received her bachelor's degree in wildlife resources from the University of
Idaho in 1982. After completing her degree she examined the research program at Glacier National
Park and summarized all science conducted in the
park. Later she was co-principal investigator during studies of boreal owl ecology. She worked with
Oz Garton exploring methods to examine the vulnerability of wilderness wildlife to recreation impacts and to study the demography of trumpeter
swans in the tri-state population. Most recently she
co-authored a review of the effectiveness of the endangered species recovery plans (Science 262:976977). She currently devotes a majority of her time to
her two sons Isaac and Philip, and she trains her
appaloosa for jumping and dressage but volunteers
with the Rocky Mountain Forest and Range Experiment Station to remain active in research.
James R. Habeck studied botany, plant ecology,
and wildlife management at the University of Wisconsin, Madison where he received his B.S., M.S.,
and Ph.D., completing his final degree in 1959. He
began teaching at the University of Montana soon
after receiving his doctorate and continued in the
capacity of Professor of Botany and Wildlife Biology until 1992 when his status changed to Post-retirement Professor of Organismal Biology and Ecology at the University of Montana. He continues to
work as a consultant for the USDA Forest Service
Research Natural Area Program and with the Northern Region's fire management program. While serving at the University of Montana he was granted
Visiting Professorships in forestry and fire ecology
at the University of Melbourne, Australia, and at
CSIRO research center at Darwin and Perth, Australia. Jim's research interests have focused on phytosociological studies of Northern Rocky Mountain
vegetation, fire ecology of old-growth pine-larch for-
Dennis H. Knight received his Ph.D. in plant ecology from the University of Wisconsin in 1964. After
teaching two years at a university in Ecuador, he
joined the faculty of the Botany Department at the
University of Wyoming. He is now head of the Department there. His research has included studies
212
on vegetation dynamics in tropical forests as well as
the forests, shrublands, and grasslands of the Rocky
Mountain region. Also, he and his students have
conducted detailed studies on the hydrology and
nutrient cycling of Rocky Mountain conifer forests.
A former president of the Ecological Society of
America, Dennis currently serves on the editorial
board of the journal Ecological Applications - a reflection of his long-term interest in applying ecological knowledge to the challenges of land managrnent.
D. Archibald McCallum studied history at
Davidson College (B.A., 1967) and biology at the
University of Colorado (1974-1977).An ardent naturalist since childhood, he served as resident naturalist for the Cottonwood Gulch Foundation
(Thoreau, New Mexico) 1977-1983, where he conducted annual breeding bird censuses, banded birds,
and initiated population studies of flammulated
owls and mountain chickadees. In 1983he returned
to academia, earning a Ph.D. with J.D. Ligon at the
University of New Mexico in 1988 with a study of
the social and population dynamics of mountain
chickadees.Following postdoctoral work on growthcurve analysis with I. L. Brisbin at the Savannah
River Ecology Lab, Arch joined the biology faculty
of College of Charleston, in his native South Carolina, in 1990. His current research interests include
population ecology of threatened species and vocal
evolution in Paridae. McCallum, his wife Caroline,
and daughter Conner live on Sullivan's Island near
Charleston, South Carolina.
Penelope Morgan teaches and conducts research
in landscape ecology, fire ecology, and forest ecology applied to management of wildland ecosystems.
Intrigued by field ecology since high school, Penny
earned her B.S. (Applied Biology--1977) and M.S.
(Forest Ecology--1979) from Utah State University
and Ph.D. in Forestry Wildlife and Range Sciences
(1984) from the University of Idaho. Following her
graduate work she joined the faculty of the University of Arizona for 2 years before returning to Idaho
as assistant professor in Forest Resources. Penny is
currently developing a broad synthetic research program on the geography and implications of disturbance. Specific research includes models of the effects of timber harvest and fire management on bird
habitat, ecosystem process modeling for management of whitebark pine ecosystems, and models of
fire regmes at fine and coarse scales. Penny's work
extends overseas with programs in Gambia, Ecuador, and Portugal. She will be the lead instructor for
a course in ecosystem inventory, analysis, and as-
sessment in the multi-agency / industry / university
program, Continuing Education in Ecosystem Management. Penny has lived all her life in the Rocky
Mountains. Her two children, ages two and five,
keep her happily occupied.
JonVemer, a native of Laramie, Wyoming, graduated from the University of Wyoming with a B.S. in
range management in 1960 and continued his studies in biology at the University of Southern Colorado. After his discharge from the U. S. Army in 1963,
Jon began his Forest Service career on the Medicine
Bow National Forest. Since then Jon served as forest
and district wildlife b i o l o p t on the San Isabel, Nebraska, Rio Grande, and Pike/San Isabel National
Forests. In the past 5 years, Jon held several special
assignments for the Rocky Mountain Region including leader of both the Mexican spotted owl center of
excellence and the forest owl conservation assessment. In 1993he was reassigned to the Rocky Mountain Regonal Office to facilitate his role in leading
the owl programs.
