The objectives of this retrospective study were 1) to characterize humeral fractures in raptors at a rehabilitation program, 2) to determine risk factors for closed and compound humeral fractures in the raptors, and 3) to investigate prognostic factors for humeral fractures in raptors. Of the 6017 birds of prey admitted over 15 years to the Université de Montréal raptor rehabilitation program, 461 birds presented with a humeral fracture. The highest occurrences of humeral fractures were documented in short-eared owls (33%; Asio flammeus ), Northern hawk-owls (24%; Surnia ulula ), long-eared owls (20%; Asio otus ), and Northern harriers (19%; Circus hudsonius )...

The presence of Cryptosporidium species in faecal samples of 32 sheep (Aries bovis), 10 goats (Capra circus), 1 blunt nose viper (Macrovipera lebetina lebetina), 3 Kotschy's geckos (Mediodactylus kotschyi) and 6 wild stellagamas (Stellagama stellio cypriaca) in Cyprus were investigated by polymerase chain reaction (PCR) and sequencing. Cryptosporidium species were found in 9/32 sheep, 5/10 goats, 2/3 Kotschy's geckos and 2/6 stellagamas faecal samples based on the sequencing of the 18S rRNA gene. Subtyping was achieved based on the sequencing of the gp60 gene...

Data from wildlife rehabilitation centers (WRCs) can provide on-the-ground records of causes of raptor morbidity and mortality, allowing threat patterns to be explored throughout time and space. We provide an overview of native raptor admissions to four WRCs in England and Wales, quantifying the main causes of morbidity and mortality, trends over time, and associations between threats and urbanization between 2001 and 2019. Throughout the study period, 14 raptor species were admitted totalling 3305 admission records...

For both adult and child readers of English, the first letter of a word plays an important role in lexical identification. Using the boundary paradigm during silent sentence reading, we examined whether the first-letter bias in parafoveal preprocessing is phonologically or orthographically driven and whether this differs between skilled adult and beginner child readers. Participants read sentences that contained either a correctly spelled word in preview (identity; e.g., "circus"), a preview letter string that maintained the phonology but manipulated the orthography of the first letter (P + O- preview; e...

Medical management of the circus performer encompasses a wide variety of multicultural, transdisciplinary and multifaceted decision-making considerations. There is a paucity of research evidence investigating both the unique diversity of skill sets and cultural considerations in addition to injury patterns of performers within the circus environment. Since a previously established framework for supporting the health and well-being of the circus performer across various aspects of medical management does not exist in the literature, most recommendations in this regard must come from practical experience working with this highly specialized performance athlete population...

BACKGROUND: While dementia is predominantly associated with cognitive impairments, communication and participation in social activities have been reported as areas where people with dementia experience immense challenges. The extent to which a person with dementia is able to participate in communicative activities does not only depend on the severity of the individual condition, but also on the interactional environment, the actions of co-interlocutors and the organization of the material surrounding...

BACKGROUND: Complete fractures of the third metacarpal/metatarsal bones (Mc/t3) are not common, but can occur in various situations and all types of horses, contributing for approximately one third of all long bone fractures in the horse, mostly related to external trauma or to high energy injuries. To stabilize Mc/t3 fractures in the horse, conservative management with walking casts and/or open reduction and internal fixation techniques are referred in the scientific literature, these last one generally by double platting application to bone surface in 90 degrees...

Chimpanzees used as pets and in the entertainment industry endure detrimental living conditions from early infancy onwards. The preferred option for ending their existence as pet or circus chimpanzees is their rescue and transfer to a primate sanctuary that will provide them with optimal living and social conditions, so that they can thrive. In this case study, we had the rare opportunity to compare the activity budgets of three chimpanzees from their time as pets in 2004 to their time living at the MONA sanctuary in 2020, after almost a decade in the centre...

Korean teeterboard is a circus discipline that consists of a board pivoted at its centre upon which two acrobats are catapulted in turn performing acrobatic jumps. This paper presents one of the first studies that focuses on investigating the factors that contribute to jump height in Korean teeterboard. A total of 120 jumps were recorded from two acrobats using motion capture. Selected variables were input to a Boosted Regression Trees (BRT) analysis, corresponding to three specific events: acrobat landing, rotation of the teeterboard and acrobat take-off...

BACKGROUND: The Watson Instability Program (WIP1) is current best evidence for conservative management of atraumatic shoulder instability, but it is unknown if this program can be effectively delivered via tele-consultation. The purpose of this longitudinal pre-post intervention study was to determine the effects of the WIP1 on patient-reported outcome measures, scapular position, shoulder strength, and handstand stability in student circus performers with atraumatic shoulder instability when delivered via tele-consultation...

Summary: The iconic photograph 'A Jewish Giant at Home with his Parents in the Bronx, NY, 1970' by the famous American photographer Diane Airbus (1923-1971) shows the 2.34 m (7 ft. 8¼ in.) acromegalic giant Eddie Carmel (1936-1972) and his parents in the living room of their New York home. The picture is a typical example of Arbus' style. The relationship between the artist and the tall subject is described. A growth hormone-secreting pituitary macroadenoma was unsuccessfully treated with two cycles of pituitary radiotherapy achieving a 7000 rad cumulative dose and by incomplete pituitary surgery...

There is fascination with the bright lights and high-risk stunts of circus performances that originated in 18th-century Paris. The idea began as a way to display the impressive horsemanship skills of trick-riders. In London, England, former cavalry Sergeant-Major Philip Astley (1742-1814) created a grand performance of horseback riders by adding several unique acts to distinguish his show. Astley's original riding school would later become his own circus, the Amphitheatre Anglais. By 1782, the Amphitheatre Anglais could boast of performances by acrobats, jugglers, gymnasts, and tight-rope walkers...

The ventral face of the wings of the butterfly Dione vanillae is covered with bright and shiny silvery spots. These areas contain densely packed ground- and coverscales with a bright metallic appearance reflecting more than 50% of light uniformly over the visible range. Our analysis shows that this optically attractive feature is caused by the inner microstructure of the scales located in these areas. Electron microscopy of cross sections through the scales shows that upper and lower lamina, supporting trabeculae, and topping ridges can be approximated by a 'circus tent'-like geometry...

Marsh harrier ( Circus aeruginosus ) is a species with obligatory cainism, in which hatching asynchrony creates a pronounced size hierarchy in nestlings. The size-related competitive advantage of older nestlings means that they tend to dominate the younger ones, and brood reduction occurs in most nests. The aim of the study was to reference values and carry out a haematological examination in order to evaluate the physiological status and health of nestlings with respect to hatching order, brood size, and nest initiation date...

Individuals´ distribution across habitats may depend on their personality. Human activities and infrastructures are critical elements of the landscape that may impact the habitat selection process. However, depending on their personality, individuals may respond differently to these unnatural elements. In the present study, we first investigated whether some human infrastructures (buildings, roads and paths) shaped Montagu's harrier nest spatial distribution in the landscape according to female personality (boldness)...

OBJECTIVE: To explore the subjective experiences of student circus arts performers with atraumatic shoulder instability undertaking a 12-week shoulder rehabilitation program during the COVID-19 pandemic lockdown, in Melbourne, Australia. METHODS: Using a qualitative design, 14 circus arts students from the National Institute of Circus Arts (Australia) were individually interviewed via teleconsultation. All interviews were recorded, transcribed, and analysed using inductive thematic analysis...

BACKGROUND: Members of the genus Sarcocystis are protozoan parasites characterized by a prey-predator two-host life-cycle. Sarcocysts are formed in the muscles or central nervous system of the intermediate host (IH), while sporocysts develop in the small intestine of the definitive host (DH). Various birds of prey have been confirmed to be DH for Sarcocystis spp. Three Sarcocystis species, S. wobeseri, S. halieti and S. falcatula, have been identified in the muscles of birds of prey, of which the latter are known to be pathogenic and can cause encephalitis in various birds...

Despite the mounting evidence supporting positive relationships between species abundance and habitat suitability, the capacity of ecological niche models (ENMs) to capture variations in population abundance remains largely unexplored. This study focuses on sympatric populations of hen harrier ( Circus cyaneus ) and Montagu's harrier ( Circus pygargus ), surveyed in 1997 and 2017 in an upland moor area in northwestern Spain. The ENMs performed very well for both species (with area under the ROC curve and true skill statistic values of up to 0...
