Czech Syllabic-Accentual Metres (1795-1914)

This project was part of a major research project into Czech verse texts from the National Revival to the present and looked at two groups of topics from the theory and history of Czech verse. The first was the rhythm of iambic and trochaic trimeter and trochaic hexameters, with a typological distinction of variants due to individual and generational arising. The rhythmic contours of 63 sets of verses were described statistically and differences in the frequency of stresses on strong and weak positions of the metre were identified. The second part of the project concerned the Czech dactyl. The history of triple metres ranging from poets of the Enlightenment to the present day underground writer Krchovsky were traced in detail. Along with the rhythm and technique of verse, the group analysed the semantics of dactylic metres of different extents (dimeters, trimeters, etc.) and their relationships to literary genres and trends. Their findings differ totally from the assumptions of traditional metrics. A general metrical norm of dactylic verses was defined within the system of rules of correspondence by the method of generative metrics. They established a typology, specified the frequency of divergences from the norm in a range of texts and investigated their role in the style and rhythmic differentiation of poetic works.

Climate warming and vegetation response after Heinrich event 1 (16 700–16 000 cal yr BP) in Europe south of the Alps

Chironomids preserved in a sediment core from Lago di Origlio (416 m a.s.l.), a lake in the foreland of the Southern Swiss Alps, allowed quantitative reconstruction of Late Glacial and Early Holocene summer temperatures using a combined Swiss–Norwegian temperature inference model based on chironomid assemblages from 274 lakes. We reconstruct July air temperatures of ca. 10 °C between 17 300 and 16 000 cal yr BP, a rather abrupt warming to ca. 12.0 °C at ca. 16 500–16 000 cal yr BP, and a strong temperature increase at the transition to the Bølling/Allerød interstadial with average temperatures of about 14 °C. During the Younger Dryas and earliest Holocene similar temperatures are reconstructed as for the interstadial. The rather abrupt warming at 16 500–16 000 cal yr BP is consistent with sea-surface temperature as well as speleothem records, which indicate a warming after the end of Heinrich event 1 (sensu stricto) and before the Bølling/Allerød interstadial in southern Europe and the Mediterranean Sea. Pollen records from Origlio and other sites in southern Switzerland and northern Italy indicate an early reforestation of the lowlands 2000–1500 yr prior to the large-scale afforestation of Central Europe at the onset of the Bølling/Allerød period at ca. 14 700–14 600 cal yr BP. Our results suggest that these early afforestation processes in the formerly glaciated areas of northern Italy and southern Switzerland have been promoted by increasing temperatures.
