The Zittau library of Christian Weise has an extensive collection of manuscripts, among which we find a number of early modern-era chronicles relating particularly to the six towns of the Lusatian League. One of these is the Zittau Chronicle by Tobiáš Schnürer from the 16th century, preserved in a later transcription, in which he chronologically recorded the most important events of his era, including the names of members of the Town Council. Memorial and chronicle records are also included in a collection of manuscripts by Abraham Frenzel (1656-1740). This includes a preserved transcription of an early modern-era chronicle of Sorau (Żary), which details the problems of life in the town and the local authority at the time. Another of Frenzel's preserved manuscripts describes the journey through Europe made by Michael Frank at the end of the sixteenth century, including his visit to Bohemia.
Giant rosettes are ones of the most striking features of the vegetation in the high tropical Andes, with Coespeletia moritziana reaching the highest altitudes up to 4,600 m a.s.l. Different from other giant rosettes, this species grows on rock outcrops with poorly developed soils and where water availability may be limited. Two questions are addressed in this study: How does this species respond in terms of water relations to maintain favorable gas-exchange conditions? Considering that adult plants rely on a water-reserving central pith, how do early stages respond to this environment’s extreme conditions? Water relations and gas-exchange studies were carried out on juveniles, intermediate and adult C. moritziana plants during wet and dry seasons in Páramo de Piedras Blancas at 4,200 m a.s.l. Adult plants maintained higher leaf water potentials (ΨL) during the wet season, however, no differences between stages were found for the dry season. Minimum dry season ΨL were never near the turgor loss point in any of the stages. Juveniles show a more strict stomatal control during the dry season to maintain a favorable water status. Net photosynthesis significantly decreased in intermediate and juvenile stages from wet to dry seasons. Our results suggest that
