The Impacts Of Embryonic Arsenic Exposure Of Fundulus Heteroclitus, Torey Bowser
The Impacts Of Embryonic Arsenic Exposure Of Fundulus Heteroclitus, Torey Bowser
Electronic Theses and Dissertations
Arsenic is a toxic metalloid that exceeds safe drinking water standards in groundwater in many locations worldwide. Arsenic exposure in fish has been linked to destruction of gill tissues, impairment of growth, decreased muscle mass, memory impairment, increased aggression, and avoidance behaviors. We examined the behavior of mummichogs (Fundulus heteroclitus) following arsenic exposure during development in two studies. Embryos were collected from fish from three reference sites: Scorton Creek (SC), Massachusetts, Wells Harbor (WE), Maine, and Block Island (BLOC), Rhode Island and two contaminated sites: Callahan Mine (CM), Brooksville, Maine, and New Bedford Harbor (NBH), Massachusetts. Embryos were …
Effects Of Anthropogenic Light And Noise On Anuran Breeding Behavior, Ashley Kobisk
Effects Of Anthropogenic Light And Noise On Anuran Breeding Behavior, Ashley Kobisk
Electronic Theses and Dissertations
The natural environment can be negatively impacted by a variety of human activities, including the production of artificial light at night and anthropogenic noise. Recent studies suggest that pollution from anthropogenic light and noise alters animal behavior. Despite being highly nocturnal and vocal animals, little attention has been given to anurans and the effects artificial light at night and anthropogenic noise have on their behavior. This study investigated the effects of artificial light at night and anthropogenic noise on anuran breeding systems in eastern Texas. Specifically, this study investigated whether (1) artificial light and anthropogenic noise altered calling behavior in …
The Effects Of Habitat Fragmentation On Avian Mobbing Behavior, Jada T. Daniels
The Effects Of Habitat Fragmentation On Avian Mobbing Behavior, Jada T. Daniels
Electronic Theses and Dissertations
Habitat fragmentation has negative effects on bird species diversity, as well as reproductive success of some species. However, there is little comparative information on the effect it may have on bird behavior. For example, small forest fragments are likely to have fewer bird species and individuals. This may limit the success of mobbing as an antipredator behavior because mobbing success depends on recruiting other birds to the group. This possibility has never been tested. The objective of my study is to quantify the effects of forest size on mobbing behavior in forest-dwelling birds. Mobbing behavior was elicited in 100 randomly …
