A bifacial paradise—The site of Ochtmissen, Germany, and its lithic assemblage in the context of the last glacial (early MIS 4) in the north‐central European Lowland

Boreas, EarlyView.
The Palaeolithic site of Ochtmissen (Lower Saxony, Germany) was excavated in fluvial terrace deposits during the winter of 1993/1994. The current study presents, for the first time, a thorough analysis of the lithic assemblage, encompassing its primary technological and typological characteristics, as well as the type and age of the fluvial deposits ...

Dispersal, source and glass chemistry of a third tephra unit within Iceland's Settlement Layer

Boreas, EarlyView.
Tephra layers may be studied to understand the dynamics and sequence of past explosive volcanism. In Iceland, the distinctive Settlement Layer (AD ~877) underlies almost all archaeological evidence for the Norse Settlement and is preserved in soils across Iceland and as cryptotephra overseas.

Dragonfly taxonomic and functional responses to urbanized streams in southeastern Europe, with management recommendations

Insect Conservation and Diversity, EarlyView.
Urbanization drives turnover in dragonfly species composition, traits, and habitat conservation value. Natural stream sections have a higher conservation value (higher DBI) due to presence of specialists. Properly managed urban streams can support diverse dragonfly assemblages.

Reflexions on the First to Second Mesolithic transition based on the stratigraphy from the Cuzoul de Gramat rock shelter (south-west France)

Българско е-Списание за Археология, 2019
At the turn of the 7th millennium cal. BC the European Mesolithic underwent a major transformation in its technical traditions. This break is marked by a complete renewal of the lithic industries, with the disappearance of the production of bladelets (or

Ariadnema polymorpha gen. et sp. nov. (Scytonemataceae, Cyanobacteria): A new heterocytous cyanobacterium with true and false branching from ruins in the Brazilian Atlantic Forest

Journal of Phycology, EarlyView.
Abstract A novel heterocytous Cyanobacterium, Ariadnema polymorpha gen. et sp. nov., was observed in the northern Brazilian Atlantic Forest (BAF), a globally significant biodiversity hotspot that has microbiome diversity yet to be explored. Isolated from ancient sugarcane mill ruins within the BAF, the new genus (strain CCAPE130) exhibits a unique ...

New Perspectives on the Problems of the Exploitation Area and the Prehistoric Use of the Buda Hornstone in Hungary

Archaeologia Polona, 2018
The mountainous areas of the Carpathian basin have provided a wide spectrum of siliceous rocks for prehistoric people. Although the presence of outcrops of a kind of chert, named Buda hornstone was already known by geological and petrographic ...

Inferential communication: The primacy of external representations

Mind &Language, EarlyView.
We argue that intentionalist accounts of ostensive‐inferential communication fail to adequately explain the role of external representations in human communication. We propose that the contents of a specific form of representational communication, symbolic depictions via spatio‐temporal arrangements of objects, can be inferred without attributing ...

WHAT ONCE WAS SHALL BE AGAIN: PALAEOLITHIC BIFACES AT THE NEOLITHIC SITE OF GIV'AT RABI EAST

Oxford Journal of Archaeology, EarlyView.
Summary Giv'at Rabi East is a Pre‐Pottery Neolithic B site located in northern Israel, interpreted as a flint workshop. One area has been spatially identified as a ‘biface locality’; it is characterized by the presence of finished axes and preforms alongside débitage. Interestingly, Acheulean bifaces have also been recovered from this area.

Alternative approaches to dryland reclamation enhance vegetation cover and soil stability at a former uranium mine

Restoration Ecology, EarlyView.
Abstract Introduction Conventional reclamation methods to recover dryland ecosystems after mineral extraction often have low success. Alternative reclamation techniques may help overcome the many challenges to establishing persistent native vegetation and stable soils.

First assessment of brush‐harvested native seed mixes in southern Brazilian grasslands

Restoration Ecology, EarlyView.
Abstract Introduction The restoration of grassland ecosystems in southern Brazil remains limited by the absence of a structured supply chain for native seeds and seedlings. Objectives Here, we present the first evaluation in Brazil of mechanized, multi‐species seed harvesting from native grassland remnants using a brush harvester.
