A First Step Towards Understanding Sperm Whale Communication and Behavior
We present two tools for annotating and preparing animal audio and movement data for downstream modeling tasks. We present a modification of VisionTransformer which detects and classifies animal communication into an annotated format. We give a visualization tool to create estimates for animal …

Essays on Communication
… philosophy and biology is the nature of communication. Early accounts of communication tended to focus on just one side of the communicative divide – the speaker side or the receiver side – and took as their starting point the case of human language. Animal communication, historically, …

Waggle Dance Your Own Way: Individuality, Network Structure, and an Herbicide Stressor in Recruitment, Foraging, and Neurobiology in the Honey Bee (Apis mellifera L.)
… mellifera L.) is perhaps the most celebrated animal communication behavior. With a waggle dance, a forager bee who has discovered a profitable resource on the landscape, usually floral nectar or pollen, can inform her nestmates of its location and recruit them to exploit it by communicating …

ΟΙΚΟΛΟΓΙΑ ΤΩΝ ΔΙΠΛΟΠΟΔΩΝ ΣΕ ΜΕΣΟΓΕΙΑΚΟΥΣ ΒΙΟΤΟΠΟΥΣ ΚΩΝΟΦΟΡΩΝ ΤΗΣ ΝΟΤΙΑΣ ΕΛΛΑΔΑΣ
… B. THE ORGANIZATION AND PARTICULARITY OF THE ANIMAL COMMUNICATION SUCH AS MILLIPEDE COMMUNITIES OF GREEK MEDITERRANEANECOSYSTEMS AND C. THE ECOLOGY OF MILLIPEDES IN MEDITERRANEAN ECOSYSTEMS. THE CONCLUSIONS DERIVED ARE THE FOLLOWING: 1. THE ABUNDANCE AND SPECIES RICHNESS AREDETERMINED BY THE …

A Brain for Language and the Language of the Brain
… spaces by the brain. We investigate a case of animal communication, that of songbirds. We show that there exists in the auditory brain of canaries a topographic representation of song, whereby song components are mapped into unique patterns of activity, preserving stimulus identity as well as …

Understanding the development, evolution, and function of bullseye pigmentation patterns in Hibiscus trionum
… of these patterns, and their exact role in plant-animal communication are not well understood. My PhD adds to current understanding of petal patterns by investigating the development, evolution, and function of the bullseye pigmentation pattern on Hibiscus trionum petals. The bi-coloured bullseye …

Ecological Pressures Selecting for Singing Behavior in Primates
… and on theories on the function of song in animals and music in humans. Specifically, I used computational statistical techniques to test the dual hypotheses that precision limb landing, as required in navigating complex arboreal topologies, could have not only shaped primate morphology, but …

Polymorphic mating signals and female choice in an Amazonian frog
… between males and females of a model in animal communication and close relative of P. petersi, the túngara frog, Physalaemus pustulosus. The results constitute the first comparison between males and females in the ontogeny of the vocal apparatus of a common frog, and contribute to the …

Natural and Experimental Noise Affects Acoustic Communication in Songbirds
… 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 unclear. …

Polarity establishment and signalling mechanisms controlling patterning in Hibiscus Trionum petals
… surfaces and these patterns can mediate plant-animal communication. Hibiscus trionum flowers produce a striking bullseye pattern by specifying cells with different pigmentation, shape, and texture in different regions of the adaxial petal epidermis. However, the mechanisms controlling cell …

Biologically-inspired Structural Color: Material Design and Fabrication Strategies Drawn from Nature’s Color Palette
… with functional uses in mating, warning, communication, defense and more. Structural color provides a fascinating case study for exploring the role of material design on macroscale properties and can provide insights on animal evolution, photonic devices, human and animal communication, …

Drumming Trees and Stone Percussion: An Evolution of Rhythm
… drumming in wild chimpanzees as a cultural communication system. The second half of the thesis examines rhythmicity in tool use and manufacture, culminating in an experimental archaeology study that assesses rhythm and Achulean hand-axe quality. *Chimpanzee Buttress Drumming* examines …

Relating behavioral context to acoustic parameters of bottlenose dolphin (Tursiops truncatus) vocalizations
… for determining identity of the vocalizing animal in a lagoon was developed. This method combined passive acoustic localization with video sampling to determine which animal vocalized. It fills an urgent need for unbiased identification of vocalizations of undisturbed dolphins where details …

Development and functions of signature whistles of free-ranging bottlenose dolphins, Tursiops truncatus
This thesis presents data on the development and functions of individually distinctive signature whistles of free-ranging bottlenose dolphins, Tursiops tnmcatus. Research was conducted at a study site near Sarasota, Florida, where a resident community of bottlenose dolphins have been the focus of a …

Maintaining contact : design and use of acoustic signals in killer whales, Orcinus orca
… on signal features that might be useful for animals to maintain contact and coordinate activities with preferred associates, including: distinctiveness by group or individual, call amplitude, and directionality cues that might cue the direction-of-movement of the signaler. Research was …

Techniques for studying vocal learning in bottlenose dolphins, Tursiops truncatus
The objective of this thesis is to develop the methods necessary for evaluating the role of learning in the natural whistle development of bottlenose dolphins. Bottlenose dolphins provide a unique opportunity to study social influences on vocal learning in a highly social non-human mammal. Vocal …

Harbor Seal (Phoca vitulina) Reproductive Advertisement Behavior And The Effects Of Vessel Noise
<p>Harbor seals (Phoca vitulina) are a widely distributed pinniped species that mate underwater. Similar to other aquatically mating pinnipeds, male harbor seals produce vocalizations during the breeding season that function in male-male interactions and possibly as an attractant for females. I …

Variation in sound production of the blue catfish, Ictalurus furcatus.
The blue catfish, Ictalurus furcatus, is an invasive species introduced to Virginia in 1974 and is the largest catfish in the United States. Like other Ictalurids, they are capable of producing disturbance calls via stridulation of the pectoral spine. These sounds can be made in air and water, and …
