Weathering The Storm: Physiological And Behavioural Responses Of White-Throated Sparrows To Inclement Weather Cues, Andrea C. Boyer
Electronic Thesis and Dissertation Repository
Changes in weather patterns and extreme weather events are becoming more common with the onset of climate change. This predicted increase in severe weather globally is alarming and it draws concern for the adaptability and ultimate survival of many species. It is clear that birds are able to cope with and respond to inclement weather with physiological and behavioural responses in many circumstances, but as environmental conditions become more severe, the adaptive coping responses of many species may be pushed to their limit. As such, it is important to understand the effects that such changes in environmental conditions will have …

Effect Of Stress And Methylmercury Exposure On Song Sparrows (Melospiza Melodia) Energy Balance., Claire Bottini

Mercury is an endocrine disruptor well known for its deleterious impacts on wildlife and humans but its effects on songbirds’ populations still require more investigation. In their natural habitat, birds face multiple stressors (e.g. predation, food unpredictability, inclement weather) in addition to pollutants. However the accumulated effects of both stress and pollutants are rarely studied. Such co-occurring pressures may synergistically increase risk for birds as both stress and mercury exposure may disrupt energy acquisition and/or allocation. My project aims to determine the interactive effects of stress and mercury exposure on songbird energy balance. Adults’ song sparrows (Melospiza melodia) …
