Project Description:  The Northern Dusky Salamander was first documented in the state of Michigan in September 2004 at Murphy Lake State Game Area, Tuscola County, Michigan. In 2004 and 2005, research was conducted that determined the range of the population within the game area and an effective method for monitoring the population. In 2006, a habitat use investigation was conducted on terrestrial salamanders in the game area, which included the Northern Dusky Salamander and the Red-backed Salamander. Anecdotal data from this investigation suggested that there was an interaction between the Northern Dusky Salamander (possibly an introduced species) and the Red-backed Salamander (a native species). In 2007, a preliminary field study was set up to investigate this potential interaction and results suggested that competitive exclusion of Red-backed Salamanders by Northern Dusky Salamanders is occurring. The current project will continue these investigations of the competitive exclusion of Red-backed Salamanders by Northern Dusky Salamanders, as well as gather information on movements (using fluorescent powder tracking) and home ranges for both of these species.

Semesters Desired:  Fall 2009

GSRA Position Description:  May-November: Check artificial cover objects (ACOs) at least three times to determine SVL and MASS of animals, perform time constrained searches (TCSs) at least three times, mark salamanders (with fluorescent powder) and measure home range movements of salamanders. Remainder of Fall semester will be used for data entry into computer databases, data analysis, preparation of presentations for professional conference and thesis defense.

Specific Day/Time Requirements:  None specified

Special Requirements:  The GSRA must be able to do the following: 1) identify salamanders of Michigan, 2) conduct field work in rugged terrain under a variety of weather conditions, 3) demonstrate experience in handling and/or working with amphibians, 4) use various computer programs, including Excel and PowerPoint, 5) work effectively and appropriately with others.
