The Effects Of Flooding On The Microbial Communities Of Sparrow Eggs In A Temperate Maine Salt Marsh, Mattie Paradise Apr 2014

The Effects Of Flooding On The Microbial Communities Of Sparrow Eggs In A Temperate Maine Salt Marsh, Mattie Paradise

Honors College

Microbial infection has been shown to reduce hatching success for the eggs of tropical birds. In these ecosystems, humidity and temperature encourage bacterial growth and the transport of microbes through the pores of the egg shell. A single study in a temperate ecosystem found no noticeable change of microbial communities during the length of the incubation cycle, and thus no increased risk of microbial infection by the time of hatching. This study, however, took place in the arid Mediterranean type climate of California, a locale that likely diminishes the abilities of microbial communities to colonize and grow on egg surfaces. …

Effect Of Forest Vegetation On Nest-Site Selection By Spruce Grouse Across Two Spatial Scales, Nathaniel Scott Parkhill Apr 2014

Effect Of Forest Vegetation On Nest-Site Selection By Spruce Grouse Across Two Spatial Scales, Nathaniel Scott Parkhill

Honors College

The spruce grouse (Falcipennis canadensis) is a gallinaceous bird that is threatened or endangered throughout much of the southeastern limit of its range. Generally associated with short-needled conifer forests like those characteristic of northern Maine, this species may be particularly sensitive to recent changes in timber harvesting practices. I examined nest-site selection to better understand spruce grouse habitat associations in northern Maine. In the summer of 2013, I located the nests of 12 female spruce grouse in commercially-managed forests of north-central Maine. I measured vegetation characteristics at nests and at sampling points 30 meters from nests, as well …
