- Description:
- Morphological, anatomical, and physiological leaf traits of Corylus avellana plants growing in different light conditions within the natural reserve "Siro Negri" (Italy) were analyzed. The results highlighted the capability of C. avellana to grow both in sun and shade conditions throughout several adaptations at leaf level. In particular, the more than 100% higher specific leaf area in shade is associated to a 44% lower palisade to spongy parenchyma thickness ratio compared with that in sun. Moreover, the chlorophyll (Chl) a to Chl b ratio decreased in response to the 97% decrease in photosynthetic photon flux density. The results highlighted the decrease in the ratio of Chl to carotenoid content, the maximum PSII photochemical efficiency, and the actual PSII photochemical efficiency (ΦPSII) associated with the increase in the ratio of photorespiration to net photosynthesis (PN) in sun. Chl a/b ratio was the most significant variable explaining PN variations in shade. In sun, PN was most influenced by the ratio between the fraction of electron transport rate (ETR) used for CO2 assimilation and ETR used for photorespiration, by ΦPSII, nitrogen content per leaf area, and by total Chl content per leaf area. The high phenotypic plasticity of C. avellana (PI = 0.33) shows its responsiveness to light variations. In particular, a greater plasticity of morphological (PIm = 0.41) than of physiological (PIp = 0.36) and anatomical traits (PIa = 0.24) attests to the shade tolerance of the species., R. Catoni, M.U.

- Description:
- Řekne-li se Leonardo, vytanou nám na mysli názvy jeho nejznámějších malířských děl Madona ve skalách, Poslední večeře, Mona Lisa či Dáma s hranostajem. Teprve potom anatomické nebo technické náčrty, přestože jich je mnohem víc. Byl samouk, přitom však nejuniverzálnější z lidí v době, kdy všestrannost ještě nepatřila k nesplnitelným snům. Svými poznatky obohatil téměř všechny vědní oblasti doby, v níž žil - anatomii, fyziologii, botaniku, paleontologii, kartografii, geologii, matematiku, chemii, aerodynamiku, astronomii, optiku, mechaniku, hydrauliku i akustiku. Měl dobré důvody cítit se geniálním umělcem i učencem., Ivo Kraus., and Obsahuje bibliografii

- Description:
- The Rožmberk family legend, which derived the origin of Bohemia´s leading aristocratic dynasty from the Roman Orsini, is usually attributed to Oldřich II of Rožmberk. This attribution however relies on indirect arguments. This article argues that the Orsini claim emerged at least a generation earlier. The conclusion relies on a letter which King Sigismund of Luxembourg addressed to the city commune of Trogir in Dalmatia in 1411 and which contains an allusion to the supposed kinship. The document surveved only as a seventeenth-century copy among papers of the Dalmatian scholar Giovanni Lucio. The internal signs of the writing as well as Lucio´s scholastic profile seem to exclude the possibility that Lucio would have forged it. The early emergence of the claim contradicts neither the broader context of the Orsini legend in various regions of the late-medieval Europe, nor other fifteenth-century documents so far known on the existence of the Orsini myth within the Rožmberk family. These documents, I suggest, shouldbe read in a different way as usual., Petr Maťa., and Obsahuje poznámky pod čarou
