Mísy s perlovitě vybíjeným okrajem jsou v Čechách reprezentovány exempláři ze Slatiny a Hradenína. V kolínském muzeu je uložena ještě jedna mísa tohoto typu, pocházející údajně z Nebovid. U tohoto nálezu byla v minulosti zvažována datace do doby římské, jedná se však o exemplář italické provenience vyrobený během 2. pol. 6. až 1. pol. 5. stol. př. Kr., který se do Čech dostal jako import z oblasti Apeninského poloostrova. Jeho provenienci naznačují rovněž výsledky analýz prvkového složení materiálu, ze kterého je vyroben. Příspěvek přináší také výsledky analýzy prvkového složení materiálu mísy typu Hohmichele z Hradenína. Také v tomto případě však naznačuje prvkové složení původ mísy v oblasti Apeninského poloostrova. and Specimens of bowls with pearl-like studded rim in Bohemia include one from Slatina and another one from Hradenín. Yet another bowl of this type, supposedly from Nebovidy, is deposited in the Kolín museum. It is a specimen of Italic provenience made during the second half of the 6th to the first half of the 5th centuries BC. Results of the analyses of the elemental composition of the material used on the bowl confirm its provenience. The article quotes also the results of the analyses of the elemental composition of the material used on the Hohmichele type bowl from Hradenín. The elemental composition indicates also in this case the origin of the bowl at the Italian Peninsula.
Global climate change may act as a potent agent of natural selection within species with Mediterranean mountain ecosystems being particularly vulnerable. The aim of this research was to analyze whether the phenotypic plasticity of Sesleria nitida Ten. could be indicative of its future adaptive capability to global warming. Morphological, anatomical, and physiological leaf traits of two populations of S. nitida growing at different altitudes on Mount Terminillo (Italy) were analyzed. The results showed that leaf mass per unit leaf area, leaf tissue density, and total leaf thickness were 19, 3, and 31% higher in leaves from the population growing at 1,895 m a.s.l. (B site) than in leaves from the population growing at 1,100 m a.s.l. (A site), respectively. Net photosynthetic rate (PN) and respiration rate (RD) peaked in June in both A and B leaves [9.4 +- 1.3 μmol(CO2) m-2 s-1 and 2.9 +- 0.9 μmol(CO2) m-2 s-1, respectively] when mean air temperature was 16 +- 2°C. R D/P N was higher in B than in A leaves (0.35 +- 0.07 and 0.21 +- 0.03, respectively, mean of the study period). The mean plasticity index (PI = 0.24, mean of morphological, anatomical, and physiological leaf traits) reflected S. nitida adaptability to the environmental stress conditions at different altitudes on Mount Terminillo. Moreover, the leaf key traits of the two populations can be used to monitor wild populations over a long term in response to global change., L. Gratani, M. F. Crescente, V. D’Amato, C. Ricotta, A. R.
