The ecology and conservation of the white-winged nightjar Caprimulgus candicans

Pople, Robert Grant January 2003 (has links)
In the tradition of previous studies of threatened species, this thesis was undertaken with the aim of improving our understanding of the ecology of the White-winged Nightjar Caprimulgus candicans, and providing the information necessary to facilitate conservation efforts on its behalf. In 1998-2001, I studied a population of White-winged Nightjars at Aguará Ñu, an area of cerrado habitats within the Reserva Natural del Bosque Mbaracayù, eastern Paraguay. Over the course of three fieldwork seasons, I captured and ringed a total of 49 nightjars (34 adults and 15 young birds). Young females first bred at approximately one year old, while still in pre-definitive plumage. Young males exhibited a form of delayed plumage maturation, whereby they only attained definitive plumage following a prolonged moult spanning much of their first potential breeding season. No evidence was obtained to suggest that they succeeded in breeding while in this conspicuously intermediate state of moult. Considerable variation was noted in the plumage whiteness of definitive males, but no clear evidence was found for consistent age-related increases in white. During the breeding season, males defended small aggregated display territories, at which they conducted nuptial display flights between late August and early January. Female nightjars were responsible for all the parental care, and apparently visited male display arenas solely to obtain copulations. Chick paternity data confirmed that the study population was polygynous, with patterns of male aggregation suggestive of an exploded lek or 'landmark' mating system. Radio-telemetry studies showed that nightjars utilised home ranges of at least 20 to 40 hectares during the eight to ten months for which they were monitored. Home ranges contained a disproportionately large amount of young campo cerrado vegetation, but no forest or old campo cerrado habitats. When selecting foraging sites within their ranges, nightjars preferred younger and avoided older campo cerrado vegetation; wet grassland was utilised roughly in proportion to its availability. Observed patterns of habitat selection were potentially explained by the greater abundance of insect prey in younger habitats. When selecting daytime roost sites, nightjars preferred vegetation of intermediate age, reflecting their need for a balance between cover and ease of access. A more general analysis of patterns of sexual dimorphism within the Caprimulgidae showed that, although almost 80% of nightjar species exhibit some dimorphism of plumage whiteness, the study species was by far the most extreme case. The striking plumage of the male was partly explained by a strong positive relationship between wing white and openness of breeding habitats within the family. However, this failed to explain the complete absence of white in the female plumage, or the extent of white dimorphism shown by the species. The most likely explanation would appear to be that extreme plumage dimorphism occurred in conjunction with the evolution of polygyny and female-only care in this open-country species. The implications of these findings for the conservation of the White-winged Nightjar are highlighted, and recommendations are proposed for future work and conservation action.

Screening pohybového systému a stupeň pohybové aktivity u dětí mladšího školního věku / Screening of musculoskeletal system and level of physical activity in children of younger school age

Černá, Monika January 2020 (has links)
Title: Screening of musculoskeletal system and level of physical activity in children of younger school age Objectives: The aim of the study is to asseess physical activity of school age in primary school in Dolní Břežany and try to find the most common risk factors for motor development of children in school age. Another aim of the study is to find statistical context between flat foot and age, gender, hypermobility, shortened hamstring muscles, lumbar hyperlordosis, level of core muscles and overweight and between winged scapula and age, gender, hypermobility, shortened m. trapezius and mm. pectorales and level of core muscles. Methods: The research was carried out by using non-standardized questionnaire to assess physical activity. Level of motor development was evaluated by group of physiotherapists. The research population was chosen purposefully by contractual research which consisted of 298 children who study on primary school in Dolní Břežany. For statistical analysis of all measured was used Microsoft Excel software. These data were evaluated by Chi - squared test and logistic regression. Results: It was found that the largest number of children does sports 2-4 hours a week. The most common risk factor of motor development of children is winged scapula and shortened hamstring muscles....

BEATA MARIA/DEA VULTS! : En studie i bruket av Maria som symbol för heligt krig från korstågen till belägringen av Wien.

Ahlsén, Nils January 2019 (has links)
Beata Maria/Dea Vults is a thesis for the degree of master (one year) in theology.   The thesis explores the role of the Virgin Mary as a martial saint in catholic combat with Islam and muslims between the years 1119 AD to 1648 AD with a focus on symbolism. The paper is focusing on symbolism in war banners, patron saints and semiotic symbols on arms and armour. There are three different events or phenomenons in the study, separated in time as well as space.   Firstly the war banner used at the battle of Las Navas (1212 AD) during the reconquista of Spain. The banner of Mary with child is the prime subjekt as well as the myths appearing in the aftermath of the battle, and the ceremony that was devised from it.   The second phenomenon is the knights templars use of Mary as patron saint, and the ceremony that followed this relationship. There is also discussion of the belts worn that were related to Mary, the use of wich is attested in documents from the trials of the templars between 1307 and 1312 AD. Lastly the paper focuses on the armours of the polish winged husars of 1648 AD and the seige of Vienna. The thesis explores the relationship between the symbols of the armour of the husars and the religious views of King John III Sobieski of Poland.   The main question of the study is:   What were the meaning of the symbols of Mary as she was carried as a ritualistic symbol for war?   The subsequent questions are:   How do you trace a progression in the useage of Mary as a symbol from the templars all the way to the use of Mary as a symbol for the winged husars?   Which types of worship of Mary as a symbol were used primarliy in wars with muslims?   The paper is researched by qualitative methods including text analysis as well as semiotic symbolism reading. There are two theories used in the analysis. Smarts dimensions and Andersons and Hulls Warrior elites, with Smarts dimensions as the dominant theory.

Therapy Options for Winged Scapula Patients: A Literature Review

Normand, Samantha L 01 January 2016 (has links)
Winged scapula is a condition characterized by lateral or medial protrusion of the scapula caused by nerve damage leading to muscular paralysis. The purpose of this systematic review of literature is to evaluate the current research literature related to the effectiveness of therapy options for winged scapula. Eleven peer reviewed English language research articles published from 1998 to present were included for evaluation. Study results revealed positive therapeutic outcomes for physical therapy and scapular bracing. Results also showed positive outcomes for the use of transcutaneous electrical nerve stimulation and acupuncture for the treatment of nerve related conditions similar to winged scapula. Additional research is needed to evaluate the effectiveness of transcutaneous electrical nerve stimulation and acupuncture for winged scapula patients specifically.

Ikonografiese studie van Ou Nabye-Oosterse ivoor gedurende die Ystertydperk, 1200 v.C. - 538 v. C.

Grobler, Estelle Cornelia 02 1900 (has links)
Die Bybel is die boek wat die meeste gelees word en tog is dit moeilik om die leefwêreld van daardie era te verstaan. My doel is om ’n nuwe blik te gee op ’n paar Ou-Testamentiese simbole. Die ontdekking van ivoorobjekte in die middel negentiende eeu in Nimrud se paleise het tot groot opwinding gelei, aangesien dit met die literatuur ooreenstem. Die ivoorstukke het ’n “verhaal” kom vertel. Deur die streke se kuns te bestudeer kan ons ’n prentjie vorm van die kuns wat in die Ystertydperk in Mesopotamië en Palestina se paleise en welaf huise voorgekom het. Die ikonografie word ontrafel deur ’n paar ivoorstukke te “lees.” Ikonografie is die beskrywing en verklaring van beelde wat op bepaalde onderwerpe betrekking het. Sekere beelde kom herhaaldelik voor in Mesopotamië. In dié studie word hoofsaaklik die Gevleuelde Wesens, die Boom van Lewe, die Gevleuelde Sonskyf asook Rosette beskryf. / The Bible is widely read but it is difficult to understand the world and culture of the era that it is set in. It is my aim to provide new insight into a few Old Testament verses with their symbolic meaning. When ivory was discovered at Nimrud the discovery elicited huge excitement. The ivory pieces came to tell a story. Through studying the art of the different cultures a picture begins to appear of the palaces and homes of the wealthy in the Levant. The iconography could be “read.” Iconography is the science of interpreting the message the art wants to convey to the viewer. A few images are repeatedly showing up in the Levant during the Iron Age. In this study I am focusing mainly on The Tree of Life, the Winged Disc, the Rosette and Winged Spiritual Beings. I am attempting to discern the meaning behind these images. / Biblical & Ancient Studies / M.A. (Ou Nabye-Oosterse Studies)
