Acoustic And Visual Signals Of Species Discrimination In Competing Neotropical Wrens, Kristina Hick Nov 2015

Acoustic And Visual Signals Of Species Discrimination In Competing Neotropical Wrens, Kristina Hick

Electronic Theses and Dissertations

Animals must discriminate between individuals within their own species, and between individuals of their own species and individuals of competitor species, allowing animals to differentiate between threatening rivals, non-threatening individuals, and potential mates. Studying two competing neotropical wren species, I tested the influence of experience on species discrimination using acoustic playback. Contrary to my predictions, the playback experiment showed that species discrimination was not influenced by previous experience with a competitor species. I also studied the relative importance of acoustic and visual signals for intra- and interspecific discrimination using playback combined with presentation of visual models. The playback-and-model-presentation experiment showed …

The Roles Of Individual Variation And Female Choice In Round Goby (Neogobius Melanostomus) Acoustic Signalling, Meghan Donovan Nov 2015

The Roles Of Individual Variation And Female Choice In Round Goby (Neogobius Melanostomus) Acoustic Signalling, Meghan Donovan

Electronic Theses and Dissertations

Acoustic signalling in teleost fishes serves a variety of communicatory purposes, mostly centered around aggression and courtship. There is strong evidence that courtship calls are used by many fishes to locate mates, coordinate spawning, and for species recognition, but the possibility that these calls also act as honest signals is not yet highly explored. Calls produced by the male round goby, Neogobius melanostomus, were analyzed for dominant frequency, interpulse interval, duration and number of pulses in the call. Call characteristics were then analyzed for relationships to body morphometrics of total length, head width, total weight, and gonadosomatic index. Strong interactive …

Diet Reconstruction And Niche Of Lake Ontario Top Predators And Corresponding Prey Species, James Adam Mumby

Electronic Theses and Dissertations

Lake Ontario supports a diverse offshore fish community consisting of salmonids and forage fish with little known about the resource partitioning and habitat use of these species. To assess this, I used stable isotopes to determine the isotopic trends (forage fishes only), niche structure and overlap of both salmonids and forage fishes. I also estimated the salmonid trophic position (TP) and diet using stable isotopes. Forage fishes had high resource partitioning but was low between Myoxocephalus thompsonii and Cottus cognatus. Regional and temporal discrete subpopulations driven largely by nitrogen were only present in Alosa pseudoharengus, Osmerus mordax and Neogobius melanostomus. …

Genetic, Environmental, And Behavioural Factors Underlying Differential Growth And Alternative Reproductive Tactics In Chinook Salmon, Oncorhynchus Tshawytscha., Adriana Forest Nov 2015

Genetic, Environmental, And Behavioural Factors Underlying Differential Growth And Alternative Reproductive Tactics In Chinook Salmon, Oncorhynchus Tshawytscha., Adriana Forest

Electronic Theses and Dissertations

Alternative reproductive tactics (ARTs) in salmonids are influenced by differential growth amongst individuals. In Chinook salmon, Oncorhynchus tshawytscha, males develop into large “hooknose” males and smaller, precocious “jacks.” The production of jacks is influenced by genetics, environment, and possibly behaviour (i.e., aggression). I examined genetic, environmental, and behavioural factors underlying ARTs in Chinook salmon. By using a full-factorial breeding design, I found that jacking rate was explained by negative maternal, 12% additive, and 0% non-additive effects. I found that dams originating from low performance genetic lines produced families with higher jacking rates. I found that both rearing environment and sire …

Bioenergetics Modeling To Assess Aquatic Invasive Species Trophic Impact, Nickolas John Kosmenko Nov 2015

Bioenergetics Modeling To Assess Aquatic Invasive Species Trophic Impact, Nickolas John Kosmenko

Electronic Theses and Dissertations

Energy requirements of aquatic invasive species (AIS) relative to native species may help explain differences in trophic impact, as species requiring more energy must consume more food, depleting resources more quickly. Variables relating to energy use were compared between co-existing invasive and native fish species in invaded habitats. Most comparisons (8/12) demonstrated higher rates in invasive species (1-46% greater), suggesting high trophic impact is a characteristic of AIS and should be of consideration in management. Bioenergetic mass-balance principles indicate energy consumed by a fish is offset by metabolic (~40%), waste (~30%), and growth (~30%) demands. Since routine metabolic rate data …

Cognitive-Affective Processing, Sleep Quality, And Mood In Obstructive Sleep Apnea, Ciaran Michael Considine Nov 2015

Cognitive-Affective Processing, Sleep Quality, And Mood In Obstructive Sleep Apnea, Ciaran Michael Considine

Electronic Theses and Dissertations

OBJECTIVES : Extant experimental research implicates sleep disturbance as causal to dysregulation of emotional processes and neurocognitive functioning. Clinical research with psychiatric samples suggests that sleep disturbance may be an etiological or sustaining factor in certain conditions, rather than solely a symptom. Recently proposed models have hypothesized cognitive-affective processing (CAP) as a potential mediator for the relationship between sleep disturbance and depressed mood. This study investigated relevant neuropsychological and sleep-physiological variables to explore the applicability of this type of model within a sleep apnea referral sample. METHODS: 61 participants referred for polysomnogram also completed self-report measures of mood and sleep, …
