Drumming Behavior of Selected North American Stoneflies (Plecoptera)

Maketon, Monchan 12 1900 (has links)
Drumming is first described for five North American stonefly species, Acroneuria evoluta, Doroneuria baumanni, Isoperla namata, Chernokrilus misnomus, and Pictetiella expansa. Signals of Acroneuria lycorias, Phasganophora capitata and Isoperla signata are further described. Drumming was not recorded from Amhinemura delosa. Signals of A. evoluta are the most complex yet recorded in Plecoptera. Doroneuria baumanni, P. expanse, C. misnomus and P. capitata have 2-way exchanges. Male D. baumanni produce two prolonged beats by rubbing the hammer on the substratum; male-female signals are non-overlapping in the first two species and overlapping in the latter two. Female P. capitata answered with an unusually long sequence of beats. Two male Isoperla species produced monophasic calls without female answers. Female A. lycorias answered taped male signals with monophasic signals like all observed females.

Sound Production of the Spotted Catfish (Arius maculatus) in Cigu lagoon, Tainan, Taiwan

Lin, Szu-Ying 03 September 2010 (has links)
According to earlier surveys, there were nine sound types in areas adjacent to the estuaries of nine major rivers in Taiwan, and the frequency range of the H-type sound was as high as 6 kHz. The producers of this sound type have not been defined yet. Sea catfish can make two kinds of sounds: stridulatory sound and drumming sound. The former is pulsed, broad-band and high-frequency, whereas the latter is harmonic, and low-frequency (less than 1 kHz). Spotted catfish (Arius maculates) is the most common demersal species in the west coast of Taiwan. The aims of the study were (1) to find out if H-type sound is presence in Cigu lagoon; (2) to describe the disturbance (hand-held) sounds emitted by A. maculates; (3) to find clues to support that the stridulatory sound of A. maculates is the H-type sound; (4) to find if there is sexual difference in the sounds of A. maculates; (5) to find the relationship between sound characteristics and intrinsic characters of the fish; (6) to define the reproductive season of A. maculates; (7) to find out if there is correlation between the spawning season of A. maculates in Cigu lagoon and presence of the high-frequency sounds in the lagoon. Bimonthly sound recordings were made in Cigu lagoon between February to December 2009. Pulsed, broad-band and high-frequency sounds were present in April, June, and August; number of sounds per minute was higher in August (mean: 52.9 sounds/ min). The sound were characterized by: sound duration: 160.6 ¡Ó 16.6 ms, dominant frequency: 2840 ¡Ó 867.3 Hz, pulse period 12.6 ¡Ó 0.45 ms, pulse duration: 6.0 ¡Ó 0.82 ms, inter-pulse-interval: 6.6 ¡Ó 0.84 ms. The stridulatory sounds of A. maculates are pulsed, broad-band and high-frequency - sound duration: 64.0 ¡Ó 16.74 ms, dominant frequency: 1251 ¡Ó 419.8 Hz, pulse period 7.7 ¡Ó 2.69 ms, pulse duration 5.3 ¡Ó 1.69 ms, inter-pulse-interval 2.4 ¡Ó 1.93 ms. Drumming sounds of A. maculates are harmonic, low frequency - sound duration: 58.5 ¡Ó 25.54 ms, dominant frequency: 442 ¡Ó 96.3 Hz fundamental frequency: 163 ¡Ó 30.98 Hz, pulse period: 6.3 ¡Ó 1.21 ms, pulse duration: 6.3 ¡Ó 1.19 ms. There was significant sexual difference in the stridulatory sound characters including pulse period, inter-pulse-interval, pulse number; females are higher than males in these parameters. There was significant sexual difference in the drumming sound (including dominant frequency) as well; males are higher than females in these parameter. Pulse period of the stridulatory sounds increased significantly with increasing standard body length. Pulse period and pulse duration of the drumming sounds both increased significantly with increasing standard body length, whereas dominant frequency and fundamental frequency both decreased significantly with size. GSI and oocyte diameters were higher in February, April, and June with a peak in April. Reproductive period was considered occurring from April to August (i.e. in spring and summer). This reproductive period coincides with the peak of vocalization. Result of ANOSIM indicates that, H-type sound is significant different from the stridulatory sound of A. maculates - they are in different groups. As the sound source might be at a distance from the recording site, energy in the high frequency range might decay with distance, whereas low frequency range might be cutoff as well. As A. maculates is the only soniferous spices in Cigu lagoon that can emit high-frequency sounds, possibility remains high that the high frequency sound, which resembles the H-type sound, in Cigu lagoon is actually produced by the spotted catfish despite of the difference in frequency-domain features of the sounds.

Three Northwest First Nations perspectives on the practice of drumming and singing: expanding the dialogue on purpose and function

Wilken, Brooke 05 November 2012 (has links)
The primary objective of this study is to explore the social functions of drumming and singing based on the perspectives of three Northwest First Nations teachers named James (ʔUu-Kwa-Qum) [pronounced: OO-Kwa-Koom] Swan of the Ahousaht Nuu-chah-nulth Nation, Ax7wil [ACKh-wheel] of the Secwepemc [She-KWE-pem] and St̓át̓imc [Stat-lee-um-c] Nations, and Spuska7 [SPU-skah] of the St̓át̓imc Nations. It further aims to determine whether the author’s etic, or outsider, perspective on function can contribute new and useful insights into how drumming and singing function in diverse First Nations cultural contexts. Community involvement prior to the initiation of this study constituted a fundamental methodological step. Such involvement resulted in the acquaintances of James (ʔUu-Kwa-Qum) Swan, Ax7wil, and Spuska7, and facilitated participation in certain drumming and singing practices. Following processes of request for teachings and ethical and informed consent, interviews were conducted with James, Ax7wil, and Spuska7, which were transcribed and used as primary resources for this largely biographical study. The method of collaborative ethnography was applied, with each chapter being provided to the respective teacher for editing three weeks prior to a follow-up editing meeting. The combination of interview data and participatory research through community involvement resulted in a unique merging of observation, experience, and interpretation from three distinct perspectives: an intercultural perspective, between Nuu-chah-nulth, Secwepemc, and St̓át̓imc First Nations; an interpersonal perspective, between James, Ax7wil, and Spuska7; and an etic perspective, from the author’s analysis of data observed, experienced, and collected. Two main conclusions were drawn from this multivalent approach: firstly, while purpose and function, as defined from emic, or insider, perspectives were often analogous, the author’s etic analysis frequently defined functions distinct from purposes emically described. This difference was tentatively attributed to the fact that function, that is, what drumming and singing effectively do for those involved, may not be fully experienced by those lacking cultural background and understanding, and thus analysed and defined according to broader criteria. Secondly, it was suggested that from the author’s etic perspective, though the purpose of diverse drumming and singing practices according to the teachings of James (ʔUu-Kwa-Qum) Swan, Ax7wil, and Spuska7 were multifarious, a general overriding function was found to be the strengthening and affirmation of specific social relationships. / Graduate

Spiritual Heritage : Understanding and Embodying Female Spirituality Through Creative Practice (1998-2004)

Goodrich, Elise January 2004 (has links)
This investigation into embodied female spirituality clearly required an approach which was able to holistically engage all human faculties - different aspects of mind, body, spirit, intuition and memory. Consequently it was essential to use my creative practice as an integrative aspect of the research. I have used my creative practice across health and healing, Sufi processes and light based media to investigate, develop and practice 'embodied female spirituality'. A shamanic-performance paradigm and feminism have been central, philosophically, to the study. In addition I have chosen to explicate the connections between these discourses of the body, the text and the imagery through my own story, my autobiography. The methodology involves two research strategies; the use of creative practice as research and the use of autobiography as a research tool. The creative practice can be seen as a continuum of modalities, extending from the private to the public. Three dimensions of the practice will be discussed. The following is a description of the dimension of a typical session in (1) a body-based natural therapy treatment I deliver (2) a group-body-based Sufi session I deliver and (3) a brief outline of the approach I have taken to the research within light based media and a list of the works.

The stonefly genus Isogenoides Klapálek (Plecoptera: Perlodidae) of North America: Systematics, behavior and ecology.

Sandberg, John Burton 05 1900 (has links)
The stonefly genus Isogenoides is revised following a holomorphological approach utilizing traditional morphology and behavioral lines of evidence. Species keys are provided for all life stages. One species, I. krumholzi (Ricker) is considered a synonym of I. doratus (Frison). Detailed species descriptions are provided for males, females, nymphs and ova. Distributions are updated utilizing all known published accounts and materials examined. The vibrational communication (drumming) behavior is reported for males and all but one species for females. The signals were species-specific and ranged in complexity from ancestral sequenced duets to derived grouped exchanges. I. olivaceus is least specialized, having mostly sequenced duets, and I. zionensis most specialized, displaying ancestral sequenced, derived grouped and complex derived exchanges containing both sequenced and grouped elements. Laboratory egg incubation experiments over a 2-4 year period show that Isogenoides has a great capacity for extended, sometimes-asynchronous diapause and hatching. The eggs of six species were incubated at a single, ca. simulated San Miguel River, Colorado, seasonal temperature regime. Direct hatch within two weeks occurred only for I. zionensis (Leopard Creek, Colorado) with small numbers hatching again after one, two, and four years. Eggs of I. doratus and I. varians hatched after an over summer, 3-5 month diapause, and I. varians again in August the next year. Populations of I. colubrinus, I. elongatus, I. frontalis and San Miguel River, I. zionensis began hatching after a 9-11 month diapause and again during spring-summer temperatures in 2nd through 4th years. I. zionensis in the San Miguel River, Colorado, exhibited a semivoltine life cycle over the two-year study period. Adults emerged in June-July when stream temperature reached ca. 11-17°C. Reared females at Quartz Creek, Pitkin, Colorado, deposited up to three egg batches. Mean fecundity of females was 691 egg/female. Oviposition in the field was observed and described. Nymphal growth was exponential from June to December, followed by slow growth until April, then declined until emergence. The greatest growth occurred between July and December as stream temperature decreased to minimum and maximum size was obtained in March while stream temperature began to increase.

The Sound of Fractions: teaching inherently abstract representations from an aural and embodied approach

Frisina, Christopher Special 10 May 2019 (has links)
Learning fractions is the focus for much of elementary school mathematics instruction because it is important and can be difficult. Fractions constitute a system of thinking about numbers and representations that differs in important ways from counting numbers. To understand fractions requires, for example, perceiving that a symbol such as 6 is not automatically associated with a larger quantity than 5 if they are denominators. In the system that constitutes fractions, 1/5 is bigger than 1/6. When students fail to master the system of fractions by a certain age, the inherent difficulty of the concepts can become confounded with discouragement, boredom, and humiliation. Music, especially percussion, not only provides an engaging context for many students but musical patterning can also provide deep analogic experiences to fractions at embodied and representational levels. Reasonable questions about musical patterns can both motivate and guide students towards understanding the properties of systems of fractions and their representations. We utilize this possibility in a new tool and associated curriculum called Sound of Fractions (SoF). SoF incorporates three main ideas to leverage musical interest and skill to provide an alternative approach to teaching fractions: Experiencing the whole and the part at the same time is crucial to learning fractions; Drumming is a compelling, embodied, culturally-relevant activity that allows students to experience the wholes, the parts, and the relationships between them at the same time; A new computer-based representational infrastructure utilizing aural, visual, physical, and temporal components that scaffolds classroom-based activities that bridge the relationship between percussion-related and mathematics activities in such a way as to gradually bring the student towards more standard mathematical representations and usages. We conducted preliminary testing of this approach in two series of after school programs with 5th-8th grade children who were significantly behind in learning fractions. Preliminary indications are that the approach is promising and ready to be tried in more formal contexts. This work illustrates that instruction rich in representational infrastructure and domains continues to be an important component of how technology can have positive impact. / Master of Science
