The spread of non‐native species

open access: yesBiological Reviews, EarlyView.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Mapping vanishing glaciers in Vorarlberg, Austria

open access: yesAnnals of Glaciology
We assess ongoing regional glacier loss in the Austrian state of Vorarlberg using a set of manually mapped glacier outlines for 2017, 2020, 2022 and 2023. Vorarlberg has lost about half of its glacierized area since a previous inventory in the mid-2000s.

Icequakes coupled with surface displacements for predicting glacier break-off

open access: yes, 2010
A hanging glacier at the east face of Weisshorn (Switzerland) broke off in 2005. We were able to monitor and measure surface motion and icequake activity for 25 days up to three days prior to the break-off.

Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

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 ...

Assessment of Glacier Volume Change Using ASTER-Based Surface Matching of Historical Photography

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2009
Glaciated regions are known to be particularly sensitive to climate change. Historical archives of glacier volume change are important, as they provide context for present-day changes.

Geological processes shaping freshwater biodiversity: a synthesis of global evidence

open access: yesBiological Reviews, EarlyView.
ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...

Sensitivity of a distributed temperature-radiation index melt model based on AWS observations and surface energy balance fluxes, Hurd Peninsula glaciers, Livingston Island, Antarctica [PDF]

open access: yes, 2012
We use an automatic weather station and surface mass balance dataset spanning four melt seasons collected on Hurd Peninsula Glaciers, South Shetland Islands, to investigate the point surface energy balance, to determine the absolute and relative ...

Volume-area scaling approach versus flowline model in glacier volume projections

open access: yesAnnals of Glaciology, 2007
Volume–area scaling provides a practical alternative to ice-flow modelling to account for glacier size changes when modelling the future evolution of glaciers; however, uncertainties remain as to the validity of this approach under non-steady conditions.

A case study showing the role of hydrophobicity variants and other enriched mAb proteoforms on filterability through a virus filter with productivity improvement measures

open access: yesBiotechnology Progress, EarlyView.
Abstract A rapid assessment of manufacturability for drug candidates is crucial for advancing a prospective biotherapeutic from a candidate to a bulk drug substance. A lot‐to‐lot approach to manufacturability is adopted where each biologic batch is assessed for manufacturability as a bulk, unfractionated pool.
