Automatic Recognition Of Frog Calls Using A Multi-Stage Average Spectrum, Wen-Ping Chen, Song-Shyong Chen, Chun-Cheng Lin, Ya-Zhung Chen, Wen-Chih Lin Sep 2009

Automatic Recognition Of Frog Calls Using A Multi-Stage Average Spectrum, Wen-Ping Chen, Song-Shyong Chen, Chun-Cheng Lin, Ya-Zhung Chen, Wen-Chih Lin

Bioacoustics Collection

The automatic recognition of animal sounds is one of the powerful techniques for replacing the traditional ecological survey method that mainly depends on manpower, which is hence both costly and time consuming. This study developed an automatic frog call recognition system based on the combination of a pre-classification method of the syllable lengths and a multi-stage average spectrum (MSAS) method. In this system, the input frog syllables are first classified into one of the four groups determined by the pre-classification method according to syllable length. Then the proposed MSAS method is used to extract the standard feature template to analyze …


Fallow Bucks Get Hoarse: Vocal Fatigue As A Possible Signal To Conspecifics, Elisabetta Vannoni, Alan G. Mcelligott Jul 2009

Fallow Bucks Get Hoarse: Vocal Fatigue As A Possible Signal To Conspecifics, Elisabetta Vannoni, Alan G. Mcelligott

Veterinary Science and Medicine Collection

Many studies of sexually selected vocal communication assume that calls remain stable throughout the breeding season. However, during this period, physiological and social factors change and these can have strong effects on the structure of calls and calling rates. During the rut, fallow bucks, Dama dama, reduce their feeding and increase the time and energy spent on vocalizing and fighting to gain matings, and consequently their body condition declines greatly. The availability of matings and intensity of competition between males also change. Therefore, we predicted that male vocal signalling would vary over time in response to the changing intersexual and …


Effect Of Noxious Stimulation Upon Antipredator Responses And Dominance Status In Rainbow Trout, Paul J. Ashley, Sian Ringrose, Katie L. Edwards, Emma Wallington, Catherine R. Mccrohan, Lynne U. Sneddon Feb 2009

Effect Of Noxious Stimulation Upon Antipredator Responses And Dominance Status In Rainbow Trout, Paul J. Ashley, Sian Ringrose, Katie L. Edwards, Emma Wallington, Catherine R. Mccrohan, Lynne U. Sneddon

Aquaculture Collection

A potentially painful experience may modify normal behavioural responses. To gauge the importance of pain relative to predation or social status, we presented competing stimuli, a predator cue or an unfamiliar social group, to two groups of noxiously treated rainbow trout, Oncorhynchus mykiss. In the predator cue experiment, fish were classified as bold or shy. Noxiously stimulated fish did not show antipredator responses, suggesting that pain is the imperative. In the social status experiment, noxiously stimulated fish held individually and undisturbed showed an increase in respiration rate and plasma cortisol. As a comparison, we used the dominant or subordinate fish …


The Effects Of The Acetic Acid “Pain” Test On Feeding, Swimming, And Respiratory Responses Of Rainbow Trout (Oncorhynchus Mykiss): A Critique On Newby And Stevens (2008), Lynne U. Sneddon Jan 2009

The Effects Of The Acetic Acid “Pain” Test On Feeding, Swimming, And Respiratory Responses Of Rainbow Trout (Oncorhynchus Mykiss): A Critique On Newby And Stevens (2008), Lynne U. Sneddon

Experimentation Collection

Newby and Stevens’ (2008) paper ‘‘The effects of the acetic acid ‘pain’ test on feeding, swimming, and respiratory responses of rainbow trout (Oncorhynchus mykiss)’’ examines the effects of a noxious stimulus on the behaviour of trout in an attempt to replicate research conducted in my laboratory (Sneddon, 2003a; Sneddon, 2007; Sneddon et al., 2003a,b; Reilly et al., 2008). However, the authors used a different protocol to the one already published and I would like to respond to some of their points of discussion to provide scientific explanations for their results using data from my laboratory. The authors show that swimming …


Prevalence Of Intestinal Parasite Infection In Symptomatic And Asymptomatic Dogs In Southwestern West Virginia: The Potential Impact On Human Health, Tashina Marie Savilla Jan 2009

Prevalence Of Intestinal Parasite Infection In Symptomatic And Asymptomatic Dogs In Southwestern West Virginia: The Potential Impact On Human Health, Tashina Marie Savilla

Theses, Dissertations and Capstones

Most dog owners are unaware of asymptomatic infection and of the possibility of contracting zoonotic parasites from their dogs. We hypothesized that parasite infection is: associated with one or more symptoms; independent of gender and age; and independent of anthelmintic usage. Stool samples were collected from 231 dogs in Kanawha County, West Virginia, and were examined by simple fecal flotation. Parasitic prevalence was found to be 23% for Ancylostoma caninum, 8% for Trichuris vulpis, 7% for Toxocara canis, 4% for Isospora species, and 32.5% overall. There was no significant relationship between infection and gender, nor between infection and symptom for …
