Fields of Interest
Ecology and management of mammalian herbivores: impacts of herbivores on natural plant communities
Courses
Research
My primary focus is the long-term effect of wild ungulates upon natural plant
communities. At Isle Royale National Park we are tracking production of available
forage and amounts of woody plants being used by moose and snowshoe hares. These
data, plus an exclosure study, underlie analyses of how herbivores can shape
the structure and species composition of forests. Elsewhere, we are analyzing
the impact of white-tailed deer on native forest herbs in southeastern Minnesota.
My second research priority addresses ecological and physiological aspects
of acquisition and conservation of sodium, an essential mineral, by mammalian
herbivores in regions where it is very low in natural forage. These studies
include field and lab experiments in Sweden. In addition, we assist forest managers
in accommodating the habitat needs of moose with silvicultural practices, using
geographic information systems and habitat-suitability models. A student has
surveyed ecological and economic impacts of the Barbary macaque, an endangered
primate, upon cedar forests in Morocco. We are comparing two methods for censusing
moose, and have developed techniques for controlling excessive deer numbers
in urban settings. We are also participating in efforts to restore woodland
caribou to Minnesota.
