This study employs non-destructive methods to investigate patterns of long bone bilateral asymmetry in a skeletal sample from the nineteenth-century peri-urban Stirrup Court Cemetery collection from London, Ontario, Canada. The St. Thomas Cemetery skeletal sample from urban Belleville, Ontario provides additional data for comparison. While one objective of the study is to determine the etiologies of any asymmetries and to identify patterns in what measurements on which bones displayed the most asymmetry, another objective is to test the hypothesis that limbs indicating asymmetry due to pathology or trauma in one element would show bilateral asymmetries elsewhere in the same bone and limb, due to either atrophy alone or to additional compensatory hypertrophy. Overall, the Stirrup Court data shows a general pattern of crossed symmetry, and when compared with the Belleville data the pattern of high and low absolute asymmetries is consistent. The results reveal a lack of asymmetry in elements with obvious long-term damage, which may indicate that caution is required in making determinations about lived impairment/disability in such cases. The sexual dimorphism in asymmetry in both samples, with males displaying more asymmetry in humeral minimum shaft circumference in the Stirrup Court sample, likely reflects the division of labor and behavior patterns in these populations. Finally, this study suggests that the effects of osteoarthritis may mask non-age-related impairment/disability, and that the skeletal record of impairment/disability is likely affected by differential preservation, with consequences for the emerging field of the archeology of disability.

Development of Rice Agrotourism Based On Sustainaable Agriculture in Maurole District. District Maurole has become one of the world's tourist destination screen sailing. Consequently, the community of Maurole District is required to provide various tourist attractions that served to tourists, including tourist attractions of rice fields. Tracing its history, tourist attractions in Maurole are available due to screen tours and benefits for farmers and local communities is not optimal. Considering the needs of farmers and the community needs to be fulfilled continuously, and the welfare must be realized, the direction of development of tourist attraction developed into agrotourism. Agrotourism is an alternative in development that leads to sustainable agriculture because its activities require farmers to conduct cultivation and conservation continuously. In addition, the principle of agronomic development based on sustainable agriculture refers to environmental balance in the long term that is beneficial to local communities, the utilization of non-destructive resources, and the benefits of social, economic, and cultures manifested well. However, empirically, agriculture-based sustainable agrotourism is not well understood in terms of knowledge, attitude, and behavior patterns of farmers, and the Maurole community, whose scope includes the concept, sustainable agronomic-based agrotourism, the actions that need to be done, and the benefits for tourists and the community in the long run. The argument encourages this important article to be socialized to provide an understanding for managers, communities, and other stakeholders in the implementation, so that more interested tourists and in turn the welfare of local communities and society generally can be guaranteed.

Potential Tool

Testosterone plays multiple roles in the regulation of development, physiology, reproduction, and behavior. Age-related testosterone declines are expected in the population. However, measuring circulating testosterone is especially challenging because concentrations are labile, responding to social situations and challenges. Matrices that integrate long-term testosterone levels are therefore valuable as biomarkers of endogenous levels as well as chronic exposures. Here, we report on a simple method to extract and measure accumulated testosterone from human fingernails using commercial enzyme immunoassay kits. Furthermore, we demonstrate known human testosterone sex and age trends. Our method is especially useful for quantifying testosterone in men’s nails, where a small amount of matrix is required. Thus, this approach is a potential tool for biomonitoring endogenous as well as exogenous testosterone exposure. We suggest considering nails as an alternative matrix for quantifying other steroids as well.

AbstractExcess consumption of high-fat diet (HFD) is likely to result in obesity and increases the predisposition to associated health disorders. Drosophila melanogaster has emerged as an important model to study the effects of HFD on metabolism, gut function, behavior, and ageing. In this study, we investigated the effects of HFD on physiology and behavior of female flies at different time-points over several weeks. We found that HFD decreases lifespan, and also with age leads to accelerated decline of climbing ability in both virgins and mated flies. In virgins HFD also increased sleep fragmentation with age. Furthermore, long-term exposure to HFD results in elevated adipokinetic hormone (AKH) transcript levels and an enlarged crop with increased lipid stores. We detected no long-term effects of HFD on body mass, or levels of triacylglycerides (TAG), glycogen or glucose, although fecundity was diminished. However, one week of HFD resulted in decreased body mass and elevated TAG levels in mated flies. Finally, we investigated the role of AKH in regulating effects of HFD during aging. Both with normal diet (ND) and HFD, Akh mutant flies displayed increased longevity compared to control flies. However, both mutants and controls showed shortened lifespan on HFD compared to ND. In flies exposed to ND, fecundity is decreased in Akh mutants compared to controls after one week, but increased after three weeks. However, HFD leads to a similar decrease in fecundity in both genotypes after both exposure times. Thus, long-term exposure to HFD increases AKH signaling, impairs lifespan and fecundity and augments age-related behavioral senescence.

Eight species of mesoplodont whales (genus Mesoplodon Gervais, 1850) named during the nineteenth century are based on valid descriptions. A checklist with the original description and type material for each of these species is provided. Additional data given may include type locality and illustrative sources, type material holding institution and type registration number(s). The only type specimen for which a record of external morphology was published relates to the 1803 stranding of Sowerby's beaked whale (Mesoplodon bidens).

Field studies were conducted in Central Negev within the breeding range of Laudakia stellio brachydactyla and in NE Israel (Qyriat Shemona) in the range of an unnamed form (tentatively “Near-East Rock Agama”), during March – May 1996. Additional data have been collected in Jerusalem at a distance of ca. 110 km from the first and about 170 km from the second study sites. A total of 63 individuals were caught and examined. The animals were marked and their subsequent movements were followed. Social and signal behavior of both forms were described and compared. Lizards from Negev and Qyriat Shemona differ from each other sharply in external morphology, habitat preference, population structure, and behavior. The differences obviously exceed the subspecies level. At the same time, the lizards from Jerusalem tend to be intermediate morphologically between those from both above-named localities, which permits admitting the existence of a limited gene flow between lizard populations of Negev and northern Israel. The lizards from NE Israel apparently do not belong to the nominate subspecies of L. stellio and should be regarded as one more subspecies within the species.

Gran Paradiso National Park

The last Capricorns (Capra ibex ibex) in the Alps survived during the nineteenth century in the Aosta valley thanks to the royal hunting reservation (today Gran Paradiso national park). Capricorns from this reservation were successfully re-introduced in Switzerland after its Capricorn population had disappeared. Currently in Switzerland there are 13200 Capricorns. Every year 1000 are hunted in order to prevent a large variation and overaging of their population and the damage of pasture. In contrast, in the Gran Paradiso national park the game population regulates itself naturally for over eighty years. There are large fluctuations in the Capricorn population (2600–5000) which are most likely due to the climate, amount of snow, population density and to the interactions of these factors. The long-term surveys in the Gran Paradiso national park and the investigations of the capacity of this area are a valuable example for the optimal management of the ibexes in Switzerland.

Book Publication

The Introduction summarizes the aims and methods of the book, explains the title, taken from Bunyan’s Pilgrim’s Progress, addresses the paradox of the otherworldly aims of religion and the worldly means of book publication, lists the principal questions the book sets out to answer and the denominations and groups covered, and points out the varied meanings of the terms ‘Methodist’ and ‘evangelical’. Despite the theological and organizational differences between these denominations and groups, they agreed on the fundamental importance of disseminating books for inculcating Christian belief and practice. To illustrate the long-term influence of such publications there is a brief analysis of Collins’s nineteenth-century series, ‘Select Christian Authors, with Introductory Essays’.

The City

This chapter charts how canonic repertories evolved in very different forms in New York City during the nineteenth century. The unstable succession of entrepreneurial touring troupes that visited the city adapted both repertory and individual pieces to the audience’s taste, from which there emerged a major theater, the Metropolitan Opera, offering a mix of German, Italian, and French works. The stable repertory in place there by 1910 resembles to a considerable extent that performed in the same theater today. Indeed, all of the twenty-five operas most often performed between 1883 and 2015 at the Metropolitan Opera were written before World War I. The repertory may seem haphazard in its diversity, but that very condition proved to be its strength in the long term. This chapter is paired with Benjamin Walton’s “Canons of real and imagined opera: Buenos Aires and Montevideo, 1810–1860.”
