SDSU Professors Collaborate To Publish
Conservation Biology Book
BROOKINGS, S.D. - Experience from 30
years of work led two South Dakota State
University professors to collaborate with
other experts in conservation biology to
publish a book titled, “Genetic Management
of Fragmented Animal and Plant Populations.”
“Climate change has created potentially
disruptive situations which means we have
to learn to manage many plants and animal
populations,” Charles Fenster, professor in
the Department of Biology and Microbiology at SDSU, said. “One example is that
certain species found on the tops of mountains in the American southwest hundreds
of years ago are now found in places such
as the Black Hills. Species have evolved to
adapt to changing conditions. The alternative is that they become extinct.”
Work on the book started in 2011. The
book provides valuable insight into how
management of fragmented plant and
animal populations can improve through
practical applications of conservation biology. Whether to maintain genetic isolation
is a major issue for managers of wild animal
and plant populations.
Fenster and Michele R. Dudash joined
others to co-author the book. Dudash is a
professor and Head of the Department of
Natural Resource Management in the College of Agriculture and Biological Sciences.
She is a population biologist. Her research
focuses on both the ecological and genetic
factors responsible for a population's persistence or demise in nature.
Fenster developed an early interest in
population dynamics and genetics. He has
focused on the conservation of biodiversity,
which this book represents. His current
work focuses on the origin of genetic diver-
sity through the study of mutations.
Dudash and Fenster are experts in
the field of inbreeding and documenting
the consequences of crosses to alleviate
inbreeding. They have worked at various
locations across the United States, earning
respect for their research and developing
relationships with other scientists conducting similar work. They accepted positions
at SDSU in Brookings in 2015 and have
continued to collaborate with experts in
their field.
The work of the couple led them to join
forces with Richard Frankham, Emeritus
Professor, Department of Biological Sciences, Macquarie University, Australia and
Jonathan D. Ballou, Scientist Emeritus,
Smithsonian Conservation Biology Institute,
Smithsonian Institution and others.
Frankham encouraged them to develop
a paper on the subject of genetic management and that idea grew into the fundamental premise for this book. That original
work has been cited over 300 times since
2011, providing the foundation for the book
which called on the talents of this group of
authors.
The value of the book comes from its
use as a tool to teach conservation biology,
conservation genetics, and wildlife management, Dudash said. The authors predict
that between 3,000 and 5,000 copies of the
textbook will provide the basis for upper
level graduate students to understand the
fundamentals of managing populations for
the future.
By making people aware of the impact
of changes, habitat can be restored. This is
what is happening with the Dakota skipper
butterfly.
“We need to get the word out and try to

actively manage populations or we let the
situation continue and watch the species
disappear,” Dudash said. “There are many
populations that have adapted to their environments. Thus there is some fear about
introducing genetic variation from populations that are hundreds of miles away.”
Fenster said prairie chickens thrive
in the Midwest. However, in Illinois, the
grassland environment where the prairie
chickens occur have been replaced by
fields of corn and soybeans. Consequently,
the few remaining populations are isolated
from one another as they exist in similarly
isolated patches of prairie. There has been
very little hatching success in that area,
leading to fewer and fewer birds, likely associated with loss of vigor following mating
between relatives. Introducing genotypes
from another state restored genetic diversity and hatching success improved. The
authors indicate that same dilemma is increasing and is faced by tens of thousands
of species. “We are not advocating for a
change in farming practices,” Dudash said.
“We want to create an awareness of what is
happening and why it happens.”
Dudash and Fenster point out in the
book that inbreeding difficulties with
wildlife can be understood by looking at the
selective breeding that takes place in cattle
herds. If animals are too closely related,
deformities such as dwarfism can result. Another example would be the concern about
dogs developing hip problems and genetic
abnormalities that occur at puppy mills.
Fenster said outbreeding depression can
occur as a consequence of animals that are
brought together from different areas in an
effort to maintain the integrity of species.
The offspring of that union may perform
less well than the individual parents.
However, the book demonstrates that even
if mixing is at first deleterious, populations
can recover and eventually thrive. It’s an
important paradigm shift in thought.
Collaborating on the book has been very
rewarding, Dudash said. “We have worked
as a team to write and edit every chapter
to make sure it is intellectually engaging
and reader-friendly. It has been a wonderful
experience to meet and learn from others in
this field.”
“We are proud to be associated with
SDSU and South Dakota,” Dudash said. “People know we are a resource. To get started
on proposing sound genetic management
decisions, we first had to pin down a definition of what is a species for conservation.
There are more than two dozen definitions
of what is a species. We needed to identify a
practical definition. Thus we wrote a paper
on this topic, which has been adopted by
the International Union for Conservation of
Nature and cited over 100 times since 2012.
That work has been incredibly impactful
at the global scale, impacting management
around the world, which is pretty exciting.”
Next chapter
“We are in the process of working on a
second book, which will be more a primer
focused at individuals who are actively
engaged in the management of species and
their habitat,” Fenster said. “The work can
apply to many systems in South Dakota. An
example would be the Badlands and need
to manage the habitat for the black-footed
ferret. The book will provide the fundamental principles with recommendations
for managers. It will provide specific ideas,
much like a cookbook."
