“…Atmospheric carbon dioxide (CO 2 ) is a primary substrate for life on Earth but is also a major driver of global-scale environmental change, causing ocean acidification (Greene et al, 2012), controlling climate variability (Retallack, 2002;Galeotti et al, 2016) and initiating mass extinctions (Jaraula et al, 2013;Veron et al, 2009). The recent rapid CO 2 rise from anthropogenic emissions is a source of ocean acidification including pH reductions and alterations in fundamental chemical balances (Doney et al, 2009).…”

Abstract. The calcareous tubeworm Spirorbis spirorbis is a widespread serpulid species in the Baltic Sea, where it commonly grows as an epibiont on brown macroalgae (genus Fucus). It lives within a Mg-calcite shell and could be affected by ocean acidification and temperature rise induced by the predicted future atmospheric CO 2 increase. However, Spirorbis tubes grow in a chemically modified boundary layer around the algae, which may mitigate acidification. In order to investigate how increasing temperature and rising pCO 2 may influence S. spirorbis shell growth we carried out four seasonal experiments in the Kiel Outdoor Benthocosms at elevated pCO 2 and temperature conditions. Compared to laboratory batch culture experiments the benthocosm approach provides a better representation of natural conditions for physical and biological ecosystem parameters, including seasonal variations. We find that growth rates of S. spirorbis are significantly controlled by ontogenetic and seasonal effects. The length of the newly grown tube is inversely related to the initial diameter of the shell. Our study showed no significant difference of the growth rates between ambient atmospheric and elevated (1100 ppm) pCO 2 conditions. No influence of daily average CaCO 3 saturation state on the growth rates of S. spirorbis was observed. We found, however, net growth of the shells even in temporarily undersaturated bulk solutions, under conditions that concurrently favoured selective shell surface dissolution. The results suggest an overall resistance of S. spirorbis growth to acidification levels predicted for the year 2100 in the Baltic Sea. In contrast, S. spirorbis did not survive at mean seasonal temperatures exceeding 24 • C during the summer experiments. In the autumn experiments at ambient pCO 2 , the growth rates of juvenile S. spirorbis were higher under elevated temperature conditions. The results reveal that S. spirorbis may prefer moderately warmer conditions during their early life stages but will suffer from an excessive temperature increase and from increasing shell corrosion as a consequence of progressing ocean acidification.

BevezetésA földtani kutatások eredményeként régóta tudjuk, hogy voltak a Föld történetében olyan, viszonylag rövid idejű környezeti krízisek, amelyek az élővilág igen jelentős megváltozását eredményezték, amikor tömegesen haltak ki fajok, nemzetségek, sőt a szervezetek nagyobb csoportjai is. Ezek a krízisek nemegyszer döntően megváltoztatták az élővilág fejlődésének további menetét. Bolygónk történetét szakaszokra tagolják és ily módon a földtörténetben mér -föld köveknek tekinthetők. Azt, hogy az ősmaradvány-együt tesekben hirtelen, jelentős változások vannak már a 19. század első felében felismerték. Ezeknél a változásoknál vonták meg a földtörténeti időszakok határát és az 1820-1840 között elnevezett időszakok (pl.: szilur, devon, triász, jura, kréta) máig érvényben vannak. 1841-ben John PHILLIPS javasolta az állatvilág fejlettségén alapuló tagolást, megalkot va a paleozoikum, mezozoikum és kainozoikum ter minusokat (MORRELL 2001).A földtörténet legutolsó, mintegy fél milliárd évének leg nagyobb tömeges kihalási eseményeit RAUP & SEPKOSKI (1982) az ősmaradvány anyag korszerű elemzésével mutatta ki. A kihalási ráta változásait ábrázoló diagramjukon öt feltűnő kihalási csúcs jelentkezik: az ordovícium végén, a ké -ső-devonban, a perm végén, a triász végén és a kréta végén. Az öt legnagyobb közt van a tehát a paleozoikum-mezozoikum és a mezozoikum-kainozoikum határa is. Ez jól mutatja, hogy az élővilág összetételének változásai ezeknél a fordulópontoknál olyan erőteljesek voltak, hogy azokat a rétegtan kialakulásának hajnalán is felismerhették a réteg -sorok tagolásán fáradozó kutatók. ALVAREZ et al. (1980) 148/1, 9-26., Budapest, 2018 Global crisis at the Triassic-Jurassic boundary and its stratigraphic record in Hungary AbstractThe mass extinction at the end of the Triassic Period was one of the largest extinction events in the Phanerozoic and it was the result of a global environmental crisis. In connection with this, the last two decades have seen increasing research efforts to gain more knowledge and thus a better understanding of this event. These efforts have included detailed studies of numerous stratigraphic sections worldwide. The review presented here attempts to summarize the major results of multi-faceted international research on the stratigraphic and fossil record of the end-Triassic event, discussing proposed cause-and-effect relationships and possible scenarios. In addition, there is also an overview of studies made in recent decades on the Triassic-Jurassic boundary sections in Hungary, with an emphasis on their relevance to global research into the Triassic-Jurassic boundary.Keywords: global environmental crisis, mass extinction, Triassic-Jurassic boundary Összefoglalás A triász időszakot lezáró tömeges kihalás egyike a fanerozoikum legnagyobb kihalási eseményeinek, amelyet globális környezeti krízis idézhetett elő.

In the Norian and Rhaetian the area of present-day Slovenia was divided into the Julian Carbonate Platform on in present north, the Dinaric Carbonate Platform in the present south and the intermediate Slovenian Basin. Main Dolomite or the Dachstein Limestone were deposited, on the platforms whereas the basin was characterized by the Ba~a Dolomite. The Upper Norian-Rhaetian succession was recently recognized in the northern part of the basin. It was studied in two sections and defined as the Slatnik Formation. Rich conodont and foraminiferal assemblages were additionally studied. Two new sections of the Slatnik Formation are presented in this paper, proving the existence of the formation across the entire northern segment of the basin. The Povdnar section is located in the continuous facies belt westward from the type-locality on Mt. Kobla. When compared to the type-locality and the other previously studied section at Mt. Slatnik, the Povdnar section exhibits more distal basinal development, where hemipelagic limestone prevails, whereas resedimented limestones occur only sporadically. For this reason, a coarsening and thickening upward trend that was recognized in previously investigated sections is poorly expressed in the Povdnar section. The second newly studied section is located on Mt. Javor where the most northwestern succession of the basin is found. In this section, the Slatnik Formation is composed solely of hemipelagic limestone.
