Using Migration Monitoring Data To Assess Bird Population Status And Behavior In A Changing Environment, Evan M. Adams
Using Migration Monitoring Data To Assess Bird Population Status And Behavior In A Changing Environment, Evan M. Adams
Electronic Theses and Dissertations
Across the world, researchers use migration banding stations to document bird migration and study the phenomenon. In this dissertation, I focus on ways of analyzing bird migration banding data and the utility migrating birds as indicators of ecosystem health that make these monitoring efforts more useful to answering ecological questions and managing migratory species. In Chapter 1, we provide background on hierarchical modeling and an overview of our findings. In Chapter 2, we developed and validated new methods to estimate daily changes in migratory population size while controlling for changes in detectability due to environmental conditions. In Chapter 3, this …

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. …
