History of Alibek Glacier based on Earth remote sensing images, bioindication and cosmogenic isopotes (14С and 10Be)

open access: yesЛëд и снег, 2015
In this article we present the reconstruction of fluctuations of Alibek valley glacier situated in the Teberda valley, Western Caucasus. The former positions of glacier of the past 120 years were reconstructed basing on the old photographs of 1904, 1921,

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

Finite element analysis of feeding in red and gray squirrels (Sciurus vulgaris and Sciurus carolinensis)

open access: yesThe Anatomical Record, EarlyView.
Abstract Invasive gray squirrels (Sciurus carolinensis) have replaced the native red squirrel (Sciurus vulgaris) across much of Great Britain over the last century. Several factors have been proposed to underlie this replacement, but here we investigated the potential for dietary competition in which gray squirrels have better feeding performance than ...

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Temporal glacier velocity variations and their controlling factors in the Nathorstbreen glacier system, Svalbard

open access: yesEgyptian Journal of Remote Sensing and Space Sciences
Temporal variations in glacier velocity are not only essential to understand glacier dynamics but also to predict glacier hazards. Therefore, in the current study, the continuous glacier velocities were estimated from 2014 to 2023 in the Nathorstbreen ...

Response of the flow dynamics of Bowdoin Glacier, northwestern Greenland, to basal lubrication and tidal forcing

open access: yesJournal of Glaciology, 2019
We use the full-Stokes model Elmer/Ice to investigate the present dynamics of Bowdoin Glacier, a marine-terminating outlet glacier in northwestern Greenland.

Glacier fluctuations and climates in the Himalayas.

open access: yesJournal of Geography (Chigaku Zasshi), 1989
Glacier fluctuations during the Holocene in the Himalayas are compared with those in the world. Characteristics of glacier mass balance in the Nepal Himalaya, which belongs to the summer-accumulation type, are described. And the glacier fluctuations after the Little Ice Age in the Nepal Himalaya are discussed on the basis of variation of summer air ...

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

open access: yesThe Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Lateglacial to Early Holocene glacier fluctuations in the northern Valaisian Alps

open access: yesSwiss Journal of Geosciences
The northern Valaisian Alps represents a glacially overprinted landscape, characterized by abundant glacial deposits and landforms. Well-preserved moraine systems, commonly found in the region, were deposited by glacier fluctuations after the Last ...

Does salinity make a difference—Kidney anatomy of Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

open access: yesThe Anatomical Record, EarlyView.
Abstract As habitat salinity markedly differs between the endangered, freshwater‐dwelling Saimaa ringed seal (Pusa saimensis Nordquist, 1899) and the brackish water‐inhabiting Baltic ringed seal (Pusa hispida botnica Gmelin, 1788), we investigated whether this difference has resulted in morphological changes to their kidneys.
