EVOLUTIONARY TRENDS AND STASIS IN MOLAR MORPHOLOGY OF RHAGAPODEMUS-RHAGAMYS LINEAGE IN THE PLEISTOCENE OF SARDINIA

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2012
Stasis, random walk and directional evolutionary patterns have been tested on the lower and upper first molars of the Rhagapodemus-Rhagamys lineage (Rodentia, Muridae) from Middle and Late Pleistocene fissure fillings of Monte Tuttavista, Orosei ...

Biogeography and diversification patterns in the Irano‐Turanian biodiversity hotspots inferred from a molecular phylogeny of the subendemic Iris subgenus Scorpiris (Iridaceae)

open access: yesNordic Journal of Botany, EarlyView.
The Irano‐Turanian Floristic Region harbors a rich flora, but our understanding of the development of this diversity is limited by a lack of data on phylogenetic relationships and biogeographic patterns of endemic and more widespread plants. Hypotheses of in situ diversification versus allopatric diversification were tested using Iris subgen. Scorpiris,

Core Slabbing and Nannofossil Analysis on the Chelungpu Fault Zone, Taichung, Taiwan

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2007
The results of this nannofossil analysis supply essential information for determining the formation boundaries in the upper Pliocene to Pleistocene. These results also verify the existence of a repetition fossil zone.

The hunt for Scabiosa trenta Hacq: how the pursuit of a phantom ignited a passion for botany and mountaineering

open access: yesNordic Journal of Botany, EarlyView.
Scabiosa trenta Hacq. was first described in 1782 by Balthasar Hacquet, with its specific epithet referring to the Trenta Valley in Slovenia. Since then, S. trenta has been the focus of numerous mountaineering and botanical expeditions, particularly by the alpinist Julius Kugy during the Golden Age of Alpinism, a period in the second half of 19th ...

Novelty for the flora of Espírito Santo, Brazil: a new species of Ouratea Aubl. (Ochnaceae)

open access: yesNordic Journal of Botany, EarlyView.
Here, we describe and illustrate the new species Ouratea oberdanii Fraga & Deccache, which is named after Dr Oberdan José Pereira. This new species is found in the mountainous regions of the evergreen Atlantic Forest in the Brazilian state of Espírito Santo. Ouratea oberdanii is similar to O. linearis (A.Gray) Sastre & Offroy and O.

Exploitation of Rabbits at the Dawn of the Holocene: Evidence From the Font Voltada Site (Northeastern Iberia) Using Comparative Neotaphonomic Models

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT During the transition from the Pleistocene to the Holocene, hunter‐gatherer societies in the northeastern Iberian Peninsula increased the number of settlements and broadened their subsistence strategies. This period is marked by the appearance of terrestrial snail accumulations attributable to human harvesting, the expansion of specialized ...

A GIS‐Based Approach to Modeling Carnivore Activity in the Pleistocene Site of Cova del Rinoceront (Iberian Peninsula)

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT A significant methodological difficulty in the interpretation of Pleistocene zooarchaeological assemblages is the identification of taphonomic agents that modify and break bones. Carnivores, in particular, have been a main focus, as competition with carnivores may have affected carcass acquisition opportunities for humans in the past.

The Age and Origin of Block Deposits in the Victorian Alps, Australia

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Large periglacial block deposits are found in the mountains of southeastern Australia. Despite their widespread distribution, their mode of formation and age are poorly understood. These landforms hold considerable potential to shed light on the nature of cooling during glacial periods. In this paper we present a new study of block deposits in
