Abstract The overlap region between the eastern fringe of the Asian westerly region and the temperate continental-monsoon climate transition zone is sensitive to climate changes and is characterized by fragile ecosystems. It is necessary to uncover the patterns of long-term historical climate variability there. A standardized tree-ring width chronology was constructed based on the tree-ring samples collected from four representative tree species in four typical areas in the overlap region, and the 203- to 343-year annual mean minimum temperature series in the overlap region were reconstructed. The reconstructed series overlapped well with extreme climate events and low-temperature periods recorded in historical data. Therefore, the reconstructed model is stable and reliable. As suggested by the reconstructed series, the variability of annual mean minimum temperature was increasingly drastic from east to west in the overlap region, with gradually shorter periodicities. In the 19th century, the high-latitude area was in the high-temperature period, and the entire overlap region experienced significant low-temperature periods lasting 20–45 years till the 1950s. The western part had an earlier start time of low-temperature periods, longer cooling duration, and slower cooling rate than the central part. The overlap region experienced a significant warming period in approximately the last half-century, with temperature increasing faster in the western and eastern parts than in the central part. The temperature variability in the overlap region was more intense in the last two centuries, with shorter periodicities and a larger proportion of cold periods. The central and western parts of the Asian westerly region, the mid- to high-latitude regions of the transition zone, and the overlap region saw significantly low-temperature periods or drastic cooling trends (the Little Ice Age) in the first half of the 19th century and significant warming trends under global warming afterwards. The influences of these changes might have been exacerbated by the westerly circulation. This study not only provides new insight into the use of dendroclimatology to extract temperature series in the Asian westerly region and the transition zone but also serves as a reference for research on global climate change.

Gonzalo Halffter developed the concept of a transition zone in Mexico during the mid-twentieth century, when he superimposed the distributional patterns of different groups of Coleoptera, finding that some groups share a common biogeographical history. The complexity of the Mexican biogeographical patterns had already caught the eyes of nineteenth-century naturalists, who tried to discern some kind of order within this biotic complexity. Herein, we analyse the original studies of different nineteenth-century authors on the distributional patterns of different Mexican taxa, highlighting the main explanations provided by them. The complexity of the Mexican biota was interpreted by Humboldt as the result of the interaction between northern and southern floras, as a taxonomic peculiarity by Augustin de Candolle, as a strong biotic replacement by Alphonse de Candolle and Sumichrast, and as different dispersal stages by Wallace. Before the theory of evolution was accepted, different biogeographical patterns (endemism, diversity and taxonomic replacement gradients, among others) had coexisted without contradictions. Botanical and zoological regions first acquired a connotation of independent centres of creation, and the wider distributions (mainly disjunct distributions) later became the backbone of hypotheses concerning historical relationships between biotas based on a dispersalist model. Nevertheless, during the 20th century, the explanations of 19th century naturalists such as the limits between regions and biotic transition entered the biogeographical debate again.

In this paper, we analyse features of the grammatical descriptions in Manchu grammar books from the Qing Dynasty. Manchu grammar books exemplify how Chinese scholars gave Chinese names to grammatical concepts in Manchu such as case, conjugation, and derivation which exist in agglutinating languages but not in isolating languages. A thorough examination reveals that Chinese scholarly understanding of Manchu grammar at the time had attained a high degree of sophistication. We conclude that the reason they did not apply modern grammatical concepts until the end of the 19th century was not a lack of ability but because the object of their grammatical descriptions was Chinese, a typical isolating language.

Levantine immigration to Chile started during the last quarter of the 19th century. This immigration, almost exclusively male at the outset, changed at the beginning of the 20th century when women started following their fathers, brothers, and husbands to the New World. Defining the role and status of the Arab woman within her community in Chile has never before been tackled in a detailed study. This article attempts to broach the subject by looking at Arabic newspapers published in Chile between 1912 and the end of the 1920s. A thematic analysis of articles dealing with the question of women or written by women, appearing in publications such as Al-Murshid, Asch-Schabibat, Al-Watan, and Oriente, will be discussed.

Purpose. The purpose of the article is to analyze and systematize the views of social and political thinkers of Galicia in the 19th - beginning of the 20th centuries. on the right and manner of organizing a nation-state as a cathedral. Method. The methodology includes a set of general scientific, special legal, special historical and philosophical methods of scientific knowledge, as well as the principles of objectivity, historicism, systematic and comprehensive. The problem-chronological approach made it possible to identify the main stages of the evolution of the content of the idea of catholicity in Galicia's legal thought of the 19th century. Results. It is established that the idea of catholicity, which was borrowed from church terminology, during the nineteenth century. acquired clear legal and philosophical features that turned it into an effective principle of achieving state unity and integrity. For the Ukrainian statesmen of the 19th century. the idea of catholicity became fundamental in view of the separation of Ukrainians between the Russian and Austro-Hungarian empires. The idea of unity of Ukrainians of Galicia and the Dnieper region, formulated for the first time by the members of the Russian Trinity, underwent a long evolution and received theoretical reflection in the work of Bachynsky's «Ukraine irredenta». It is established that catholicity should be understood as a legal principle, according to which decisions are made in dialogue, by consensus, and thus able to satisfy the absolute majority of citizens of the state. For Galician Ukrainians, the principle of unity in the nineteenth century. implemented through the prism of «state» and «international» approaches. Scientific novelty. The main stages of formation and development of the idea of catholicity in the views of social and political figures of Halychyna of the XIX – beginning of the XX centuries are highlighted in the work. and highlighting the distinctive features of «national statehood» that they promoted and understood as possible in the process of unification of Ukrainian lands into one state. Practical significance. The results of the study can be used in further historical and legal studies, preparation of special courses.

 Bodyweight exercises (also popularly known as calisthenics) is a classic training method and its practice has been widespread since the 19th century, but little evidenced in the scientific literature over the years. This type of training aims to promote multi-system adaptations using body weight as an overload with no or few implements [1–3]. This characteristic makes exercise with body weight easy to apply, in addition to having an excellent cost-benefit ratio when compared to other training possibilities that require machines or materials [4,5].
