Climate-driven Shifts in Quantity and Seasonality of River Discharge over the past 1000 Years from the Hydrographic Apex of North America [PDF]

open access: yes, 2008
Runoff generated from high elevations is the primary source of freshwater for western North America, yet this critical resource is managed on the basis of short instrumental records that capture an insufficient range of climatic conditions. Here we probe

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 ...

Assessing the dynamic changes and the effect of buoyancy of lake-terminating Yanong Glacier in the southeastern Tibetan Plateau with UAV surveys

open access: yesJournal of Hydrology: Regional Studies
Study region: Yanong Glacier, a lake-terminating glacier, in the southeastern Tibetan Plateau. Study focus: Previous researches had indicated higher mass loss of lake-terminating glaciers than land-terminating glaciers over the past few decades. However,

Permafrost Favorability Index: Spatial Modeling in the French Alps Using a Rock Glacier Inventory

open access: yesFrontiers in Earth Science, 2017
In the present study we used the first rock glacier inventory for the entire French Alps to model spatial permafrost distribution in the region. The inventory, which does not originally belong to this study, was revised by the authors in order to obtain ...

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 ...

A Hierarchical Spatio-Temporal Statistical Model Motivated by Glaciology [PDF]

open access: yes, 2019
In this paper, we extend and analyze a Bayesian hierarchical spatio-temporal model for physical systems. A novelty is to model the discrepancy between the output of a computer simulator for a physical process and the actual process values with a ...
