EDUCATIONAL BACKGROUND

PhD, Agronomy, University of Missouri - Columbia, 1988

MS, Agronomy, University of Missouri - Columbia, 1984

BS, Agronomy, Missouri State University, 1982





BIOGRAPHY

Dr. MacAdam’s graduate training was at the University of Missouri-Columbia
(UM-C) in Agronomy with an emphasis on the physiology of forage plants; her
graduate research focused on the anatomy and physiology of grass leaf
development. Following her PhD in 1988, she taught the Crop Physiology course at
UM-C for one semester and gained postdoctoral experience in animal science and
basic plant biochemistry and physiology. In 1991 she accepted a Forage research
and teaching position at Utah State University. She has served as the chair of
the Forage and Grazinglands Division of the Crop Science Society of America, as
a technical editor of the Forage and Grazinglands journal, and as an associate
editor for both Crop Science and Agronomy Journal, and is currently an editor of
the Journal of Agricultural Science, Cambridge. She was recently selected as a
Fellow of the American Society of Agronomy and the Crop Science Society of
America.





TEACHING INTERESTS

Dr. MacAdam taught the Forages course for a decade, then identified the need for
an undergraduate course in plant physiology and anatomy which she developed and
taught for a decade. She wrote a text for this course, The Structure & Function
of Plants, that has become a Wiley life sciences best seller. She has
contributed chapters on forage plant physiology, irrigation, and plant-water
relations to Vols. I and II of the Forages texts, and currently teaches the
Forages course while a colleague continues to teach the Plant Structure-Function
course.



RESEARCH INTERESTS

Dr. MacAdam’s research at USU has focused on issues of relevance to forage
production in the western U.S. The high-altitude, dry, cool western U.S. climate
is uniquely supportive of very high-quality irrigated forage legume production,
but it also results in concerns related to bloat. The added cost of irrigation
means that western livestock producers using rotational stocking of seeded
pastures need to minimize input costs. Her research has demonstrated the value
of tannin-containing legumes for organic dairy production via increased milk
production, as well as for beef finishing, achieving near-feedlot-level average
daily gains, consumer preference for legume- over grass-finished beef, reduced
enteric methane emissions, increased nitrogen retention, and reduced loss of
nitrogen to the environment. She has determined this is likely because irrigated
perennial legumes in the Mountain West climate accumulate unusually high
concentrations of non-fiber carbohydrates. Dr. MacAdam is currently screening
perennial legumes and non-legume forbs for inclusion in rangeland resource
islands of high-protein forbs designed to serve as sources of supplemental feed
for cowherds during late summer and autumn.
