Abstract

The Messinian Salinity Crisis and its precursor events have been the greatest environmental perturbation of the Mediterranean Sea to date, offering an opportunity to study the response of marine ecosystems to extreme hydrological change and a large-scale biological invasion. The restriction of the marine connection between the Mediterranean and the Atlantic Ocean already since the Tortonian-Messinian boundary resulted in stratification of the water column and increase water temperature and salinity variations. Here, we present a unified and revised marine fossil record of the Mediterranean that covers the Tortonian stage, the pre-evaporitic Messinian and the Zanclean stage and encompasses 22988 occurrences of calcareous nannoplankton, dinoflagellates, foraminifera, corals, ostracods, bryozoans, echinoids, mollusks, fishes, and marine mammals. This record adheres to the FAIR principles, it is updated in terms of taxonomy, and it follows the currently accepted stratigraphic framework. Based on this record, knowledge gaps are identified, which are due to spatiotemporal inconsistencies in sampling effort and the distribution of sedimentary facies, and the inherent differences in the preservation potential between the groups. Additionally, sampling bias in old records may have distorted the record in favor of larger, more impressive taxa within groups. This record is now ready to be used to answer both geological and biological questions, and is amendable when new fossil data are brought to light. [ABSTRACT FROM AUTHOR]

Abstract

De nombreuses universités scientifiques possèdent des collections. L’université Bordeaux 1 possède neuf grandes collections concernant les domaines de la préhistoire, de l’anthropologie, de la géologie terrestre et marine, de la paléontologie et micropaléontologie, de la biologie, de l’astronomie et d’un fonds ancien et moderne d’ouvrages scientifiques. Certaines collections sont riches de milliers de spécimens : fossiles d’invertébrés, ossements de vertébrés, silex taillés, ossements humains préhistoriques ou historiques, animaux naturalisés, carottes de sédiments, instruments d’astronomie et livres anciens. Ces collections ont été constituées par des privés ou des chercheurs et ont ensuite été léguées à l’université. Il est important d’identifier les collectionneurs et surtout les motivations qui ont guidé leurs choix : recherche, enseignement, passion. Entre histoires personnelles et histoires locales, ce regard sur les collections est aussi une porte ouverte sur l’histoire des Sciences.Most major scientific universities own numerous collections. The Bordeaux 1 University has nine large collections in various scientific fields such as Prehistory, Anthropology, Geology, Oceanography, Palaeontology and Micropalaeontology, Biology, Astronomy and patrimonial and modern scientific books and documentation. Some collections are wealth of thousands of specimens : invertebrate fossils, vertebrate bones, flints, prehistoric and historic human bones, naturalised animals, sediment cores, astronomy instruments et old books. Such collections were built up by private persons, researchers and academics who have bequeathed them to the university. It is quite important to identify all collectors and mainly to understand what were the motives which guided their choices : research, teaching, passion. Between personal and local histories, such a look at university collections is also an open door to history of sciences.

9. A new Late-glacial site with Picea abiesin the northern Apennine foothills: an exception to the model of glacial refugia of trees

Author

Ravazzi, Cesare, Donegana, Marta, Vescovi, Elisa, Arpenti, Enrico, Caccianiga, Marco, Kaltenrieder, Petra, Londeix, Laurent, Marabini, Stefano, Mariani, Stefano, Pini, Roberta, Vai, Gian, and Wick, Lucia

Abstract

We describe a new palaeobotanical site at Bubano quarry on the easternmost Po plain, northern Italy. Pollen and macrofossils from river and marsh sediments demonstrate the occurrence of Piceain a Pinus sylvestrisforest growing in a radius of some tens of kilometres south of the sedimentation place, at the beginning of the Late-glacial interstadial. The Late-glacial and Holocene history of Piceain the northern Apennines is reconstructed on the basis of the palaeobotanical record. The sharp climatic continentality increase eastwards across the northern Apennines from the Tyrrhenian to the Adriatic coast is considered significant for the survival of Piceaduring the Late-glacial. The most critical phase of survival is related to the moisture changes and consequent Abiescompetition associated with the last glacial-interglacial transition and the early Holocene. The residual spruce populations expanded during the middle Holocene. The history of Piceain the northern Apennines is a case of ineffective interglacial spread of tree populations from pre-existing stands of LGM (Last Glacial Maximum) and Late-glacial age.

Abstract

We present a summary of two round-table discussions held during two subsequent workshops in Montreal (Canada) on 16 April 2014 and Ostend (Belgium) on 8 July 2015. Five species of the genus Achomosphaera Evitt 1963 and 33 of the genus Spiniferites Mantell 1850 emend. Sarjeant 1970 occuring in Pliocene to modern sediments are listed and briefly described along with remarks made by workshop participants. In addition, several holotypes and topotypes are reillustrated. Three species previously assigned to Spiniferites are here considered/accepted as belonging to other genera: Impagidinium inaequalis (Wall and Dale in Wall et al. 1973) Londeix et al. 2009, Spiniferites? rubinus (Rossignol 1962 ex Rossignol 1964) Sarjeant 1970, and Thalassiphora balcanica Balteş 1971. This summary forms the basis for a set of papers that follows, where points raised during the workshops are explored in greater detail.
