Modelling and investigation of the role of anthropogenic noise on the collective behaviour of marine animals
… changing. With a vast increase in the amount of anthropogenic noise they are subjected to, along with the industrialisation of vast areas in our seas and oceans, the impact this may have on their survival has become an important question for industry and scientists alike.<br/><br/>In this thesis, …

Artificial Night Lighting and Anthropogenic Noise Alter Animal Activity, Body Condition, Species Richness, and Community Structure
… pollution from artificial night-lighting and anthropogenic noise have increased at a dramatic rate over the last several decades. Alterations to the sensory environment have been found to affect wildlife in a wide variety of ways including behavioral changes, physiological responses, changes …

Influences of Anthropogenic Noise on Flight Initiation Distance, Foraging Behavior, and Feeder Community Structure of Wild Birds
… 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 …

Assessing anthropogenic noise impacts and relevant soundscape cues for marine invertebrates: leveraging squid and coral reefs as model systems
… these taxa are vulnerable to adverse effects of anthropogenic noise on hearing and behavior. However, little is known about marine invertebrates’ responses to anthropogenic noise, and the ambient environmental sounds (“soundscapes”) they detect and respond to. Most acoustic studies report sound …

Effects of Anthropogenic Light and Noise on Anuran Breeding Behavior
… 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 …

A Comparison of the Singing Activity of Carolina Wrens <i>(Thryothorus Ludovicianus)</i>) in Urban and Rural Settings
… with non-native species, disturbance due to anthropogenic noise, and micro-climatic changes. Factors such as temperature, relative humidity, and noise affect the acoustical environment and may affect the ability of many animals, including birds, to communicate. Understanding how urbanization …

Investigating the ecological role of sound on coral reefs
… Reef soundscapes are also frequently polluted by anthropogenic noise, which can disrupt natural cues and negatively impact sound-sensitive taxa. This thesis aims to fill knowledge gaps in this understudied field of coral reef acoustic ecology by 1) assessing coral larval settlement responses to …

Recording, in-situ processing and near real-time satellite transmission of acoustic data from a low-cost marine drifter buoy
… widespread implementation. Rising levels of anthropogenic noise from shipping, construction, and resource extraction mask communication between marine species, disrupt behaviour, and can cause physiological harm across a wide range of taxa. This thesis addresses the critical need for more …

Natural and Experimental Noise Affects Acoustic Communication in Songbirds
<p>Background noise is ubiquitous and can impair acoustic communication and influence signaling behavior in animals. Despite evidence demonstrating myriad effects of anthropogenic noise on animal communication, precisely how natural background noise influences communication and behavior remains …

Acoustic communication in the North Atlantic right whale (Eubalaena glacialis)
… produce and overlaps the frequency range of most anthropogenic noise sources. This combination of research provides a thorough description how North Atlantic right whales use sound in SAGs and how increasing levels of noise in the oceans may impact right whales in these groups.

Biologging for marine megafauna conservation: animal tracking, environmental monitoring, and modelling approaches.
… turtles in Gabon quantified pervasive anthropogenic noise pollution in important nesting areas, highlighting an emerging threat requiring management attention. Post-release survival analysis of three shark species in UK recreational fisheries revealed high (>95%) survival rates, …

Sentinel behaviour and urban environments: A corvid’s perspective
… American crow can behaviourally adapt to exploit anthropogenic resources resulting in positive urbanization effects on corvids. While individual-level behavioural adaptations are an active area of research, social behaviour adaptations and their contribution to the success of urbanized species are …

The auditory system of the minke whale (Balaenoptera acutorostrata) : a potential fatty sound reception pathway in a mysticete cetacean
Despite widespread concerns about the effects of anthropogenic noise on baleen whales (suborder Mysticeti), we lack basic information about their auditory physiology for comprehensive risk assessments. Hearing ranges and sensitivities could be measured if customized equipment and methods were …

Assessing the potential contribution of roads to variation in British bird populations
… with vehicles can cause direct mortality, and noise, light and chemical pollution can have sub-lethal impacts. Additionally, roads can cause habitat degradation, fragmentation and edge effects. However, thus far, the published literature on this topic comprises only relatively small-scale …

The Effects of noise of Zebrafish (Danio rerio) memory
… since the start of the industrial revolution anthropogenic disturbances have increased in severity. Anthropogenic noise is one such example, which has deleterious effects on organisms in both terrestrial and aquatic habitats. The range of effects may vary from interruptions in behavioural …

Hydroacoustic Parametric Study of Pile Driving-Induced Anthropogenic Sound
Anthropogenic sound in Florida's waters and coastal waterways is most commonly caused by overwater development, marine traffic, and military activity. Overwater construction has increased over the years as a result of aging infrastructure and rising expansions around the United States, including …

Mammalian habitat use along a residential development gradient in northern Colorado
"Exurban" development occupies nearly five times more land in the United States than urban and suburban development combined. Understanding the effects of exurban development on biodiversity thus has important and wide-ranging implications for the planning, construction and stewardship of …

Harbor Seal (Phoca vitulina) Reproductive Advertisement Behavior And The Effects Of Vessel Noise
… overlap, I investigated the impacts of vessel noise on the vocal behavior of individual males. In the presence of vessel noise, male harbor seals increase the amplitude of their vocalizations, decrease the duration, and increase the minimum frequency. These vocal shifts are similar to studies …
