Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Thorncliffe Formation: A proglacial to subglacial lacustrine basin sequence, Greater Toronto Region, Canada

Boreas, EarlyView.
Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.

Palaeoglaciations in the Polar and Subpolar Ural Mountains

Boreas, EarlyView.
The Ural Mountains form a major physiographic boundary between the East European Plain and West Siberia, both repeatedly glaciated during the Pleistocene by the Barents–Kara ice sheet. Although the present‐day topography reflects significant glacial modification, the extent, chronology and interaction of mountain glaciers with the Barents–Kara ice ...

Model‐Based Cost‐Effectiveness of Direct Restorations: Amalgam Dominates

Community Dentistry and Oral Epidemiology, EarlyView.
ABSTRACT Objectives A phase‐down of dental amalgam use has been mandated and the feasibility of its phase‐out in England by 2030 is being explored. Amalgam use in English National Health Service (NHS) care still predominates for posterior restorations, though access to this care is increasingly limited.

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal

Conservation Biology, EarlyView.
Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...
