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. …
