American Journal of Botany, EarlyView.Abstract Premise Species of Deuterocohnia (17 spp.) show extraordinary variation in elevation (0–3900 m a.s.l.) and growth forms, and many have narrow geographic distributions in the west‐central Andes and the Peru‐Chile coast. Previous research using few plastid and nuclear loci failed to produce well‐resolved or supported phylogenies.

Causes of ice age intensification across the Mid-Pleistocene Transition
Proceedings of the National Academy of Sciences of the United States of America, 2017 Significance Conflicting sets of hypotheses highlight either the role of ice sheets or atmospheric carbon dioxide (CO2) in causing the increase in duration and severity of ice age cycles ∼1 Mya during the Mid-Pleistocene Transition (MPT).

Predicting ecology and hearing sensitivities in Parapontoporia—An extinct long‐snouted dolphin
The Anatomical Record, EarlyView.Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.

Glaciation of West Siberia – disputable questions and means of their solution
Лëд и снег, 2015 Different approaches to the problem of Quaternary glaciation of the North-West Siberia have been considered in the present paper, in which also analysis of glaciological situation has been done for the region.

Modeling the dynamics of glacial cycles [PDF]
, 2017 This article is concerned with the dynamics of glacial cycles observed in the geological record of the Pleistocene Epoch. It focuses on a conceptual model proposed by Maasch and Saltzman [J. Geophys. Res.,95, D2 (1990), pp.

The Anatomical Record, EarlyView.Analysis of cranial endocast data of 181 extant and 41 fossil species from Euarchontoglires shows that there was a reduction in olfactory bulb size in Crown Primates, but that there were also subsequent reductions in various other primate clades (Anthropoidea, Catarrhini, Platyrrhini, crown Cercopithecoidea, Hominoidea).

Ground ice as indicator of the Pleistocene history of the Russian Arctic
Лëд и снег, 2015 Based on the analysis of massive ground ice origin, the geological development of the Russian Arctic in the Quaternary period has been considered. A classification of massive ice with two new genetic types (submarine and coastal-marine) and new mechanism

Uppermost Pleistocene shrews (Mammalia, Soricidae) from Vaskapu Cave (N-Hungary) [PDF]
, 1999 Three shrew species (Sorex araneus LINNAEUS1758, Sorex minutus LlNNAEUS1766 and Sorex alpinus SHINZ1837) were found in the fossiliferous sediments of Vaskapu Cave, near Felsötárkány.

The relationship between form and function of the carnivore mandible
The Anatomical Record, EarlyView.Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...
