Genetic Structure Of Invasive Baby’S Breath (Gypsophila Paniculata) Populations In A Michigan Dune System, Hailee B. Leimbach-Maus
Masters Theses
Invasive species can reduce biodiversity of a system by outcompeting native species for resources, changing the physical characteristics of a habitat, and altering natural disturbance regimes. Coastal sand dune ecosystems are dynamic with elevated levels of disturbance, and as such they are highly susceptible to plant invasions. The topography, geographic distribution of preferred habitat, and disturbance regime in an ecosystem can influence where an invasive plant becomes established, its dispersal patterns, and how densely it grows. One such invasion that is of major concern to the Great Lakes dune systems is baby’s breath (Gypsophila paniculata). The invasion of …
Genetic Health And Population Viability Of Reintroduced American Marten In Michigan, Tamara L. Hillman
Genetic Health And Population Viability Of Reintroduced American Marten In Michigan, Tamara L. Hillman
Masters Theses
American marten (Martes americana) were extirpated from Michigan’s Lower Peninsula (LP) in 1911, and subsequently from the Upper Peninsula (UP) in 1939 due to habitat loss and unregulated trapping. The species was later reintroduced in the UP in the mid-1950s, and to the LP in the mid-1980s. Previous research has determined the small founding sizes used in the LP reintroductions have resulted in losses of genetic diversity, while research in the UP has produced discordant results concerning the effects of the reintroduction methods on genetic health and population structure. Since past research of marten in the LP, no …
