Health Assessment Of Two Reintroduced Populations Of American Martens (Martes Americana) In Michigan, Maria Catherine Spriggs Dec 2015

Health Assessment Of Two Reintroduced Populations Of American Martens (Martes Americana) In Michigan, Maria Catherine Spriggs

Doctoral Dissertations

The American marten (Martes americana) was extirpated from Michigan during the early-20th century due to loss of vast areas of mature conifer forest and unregulated trapping. The species was reintroduced into the Upper Peninsula (UP) and Northern Lower Peninsula (NLP) during the mid-20th century. While the American marten population in the UP has grown and is doing well, the population in the NLP has been less successful. The reasons for the limited success of the NLP population are unknown, but may include lack of suitable habitat, limited reproductive success, poor genetic diversity, disease, or negative environmental impacts. American …


Parasite Infection Mediates Trait Tradeoffs In Fundulus Heteroclitus, Sarah Dunn May 2015

Parasite Infection Mediates Trait Tradeoffs In Fundulus Heteroclitus, Sarah Dunn

Honors College Theses

To be successful, an animal must eat, grow, and reproduce. With limited resources, there are tradeoffs between these critical life history parameters but the direction of the tradeoffs is largely unknown in a changing environment. To determine whether environmental context affects life-history tradeoffs, I surveyed and quantified investment into reproduction, growth, and a proxy for immunity (parasitism), in the mummichog, Fundulus heteroclitus, a common inhabitant of salt marshes in Georgia. Three salt marsh sites along coastal Georgia (Shellman Bluff, Skidaway Island, and Tybee Island) were selected using a proxy for anthropogenic disturbance (impervious surface), which also fell along a …
