Microsatellite Analysis Of Two Local Fox Squirrel (Sciurus Niger) Populations, Sajeena R. Horvath
Microsatellite Analysis Of Two Local Fox Squirrel (Sciurus Niger) Populations, Sajeena R. Horvath
Undergraduate Honors Thesis Collection
The objective of this study was to examine the genetic diversity of two geographically separated populations of Eastem fox squirrels (Sciurus niger) within the Indianapolis metropolitan area. One population was located on Butler University's campus and the other at Eagle Creek Park, located about 6.5 miles WNW from the Butler campus. DNA was extracted from tail hair samples collected by live trapping squirrels during the summers of 2007, 2008, and 2009. I used microsatellite analysis to examine the genetic variation between the two sites. Hair samples from 66 Butler squirrels and 30 Eagle Creek squirrels were analyzed using 4 microsatellite …

Growth, Larval Development And Metamorphosis In Small-Mouthed Salamanders (Ambystoma Texanum), Nicholas Timothy Zellmer
Undergraduate Honors Thesis Collection
The small-mouthed salamander (Ambystoma texanum), a common species in the midwestern United States, lays its eggs in temporary ponds during mid to late March once they have filled with water from the melting winter snow or early spring rains. For its relative abundance in the Midwest, there is little known about the life history of this species. My research followed the growth of small-mouthed salamander larvae in ponds between hatching, which occurred in early spring (mid-April), and metamorphosis, which occurred in midsummer (early June to mid-July). The research focused on the growth, larval development, and timing of metamorphosis with special …
