Influences Of Anthropogenic Noise On Flight Initiation Distance, Foraging Behavior, And Feeder Community Structure Of Wild Birds, Alissa R. Petrelli
Influences Of Anthropogenic Noise On Flight Initiation Distance, Foraging Behavior, And Feeder Community Structure Of Wild Birds, Alissa R. Petrelli
Master's Theses
Throughout the world, birds represent the primary type of wildlife that people experience on a daily basis. However, a growing body of evidence suggests that alterations to the acoustic environment can negatively affect birds as well as humans in a variety of ways, and altered acoustics from noise pollution has the potential to influence human interactions with wild birds. In this thesis, I investigated how anthropogenic noise impacts daily behavior as well as community structure of wild birds. In the first component of this thesis, I assessed the distance at which a bird initiates flight or escape behavior (i.e., flight …
Modelling Bird Migration With Motus Data And Bayesian State-Space Models, Justin Baldwin
Modelling Bird Migration With Motus Data And Bayesian State-Space Models, Justin Baldwin
Masters Theses
Bird migration is a poorly-known yet important phenomenon, as understanding movement patterns of birds can inform conservation strategies and public health policy for animal-borne diseases. Recent advances in wildlife tracking technology, in particular the Motus system, have allowed researchers to track even small flying birds and insects with radio transmitters that weigh fractions of a gram. This system relies on a community-based distributed sensor network that detects tagged animals as they move through the detection nodes on journeys that range from small local movements to intercontinental migrations. The quantity of data generated by the Motus system is unprecedented, is on …

Impacts To Biodiversity And Ecosystem Services From Bioenergy Development: A Pan American Experience, Colin Phifer
Dissertations, Master's Theses and Master's Reports
As part of a broader project that evaluated the social and ecological sustainability of bioenergy, I studied the effects of bioenergy associated land-use change and management on native bees and birds in two bioenergy-producing countries, the United States and Argentina. In Argentina, I worked in Entre Ríos province where eucalyptus (Eucalyptus spp.) plantations are being planted. These fast-growing trees are replacing pasture and annual crops, the current dominant land use. I surveyed for native bees and birds in pastures/annual crops and large-scale eucalyptus plantations, as well as mixed-use farms and native espinal savannas. Both birds and bees declined in …
