The biofilm ecology of proglacial floodplain streams

Glacial forelands figure among the most dynamic landscapes on Earth, and their formation is currently accelerating given glacier shrinkage. Draining these forelands are streams hosting unique microbial communities, which have the capacity to impact both th ...

Ecosystem engineering by periphyton in Alpine proglacial streams

Tom Ian Battin, Davide Mancini, Marc Aguet, Adrijan Selitaj, Matteo Roncoroni

Stream periphytons are candidate ecosystem engineers in proglacial margins. Here, we quantify the extent to which they are engineers for the case of hillslope-fed tributaries in the terrace zones of proglacial margin alluvial plains. Candidate ecosystem en ...

Tether Climbing Robot for Environmental Sampling and Data Collection

Josephine Anna Eleanor Hughes, Kai Christian Junge, Max Mirko Polzin, Qinghua Guan, Nicolas Mathis Minder

Developing robots that can explore environments without disturbing the natural flora and fauna could allow a safe exploration for both the robot and its surroundings. However, this can involve exploring complex or challenging environments, for example extr ...

Unexpected post‐glacial colonisation route explains the white colour of barn owls ( Tyto alba ) from the British Isles

Nicolas Jean Philippe Guex, Christian Iseli

The climate fluctuations of the Quaternary shaped the movement of species in and out of glacial refugia. In Europe, the majority of species followed one of the described traditional postglacial recolonization routes from the southern peninsulas towards the ...

Antarctic surface temperature and elevation during the Last Glacial Maximum

Jérôme Chappellaz

The Antarctic Vostok ice core provided compelling evidence of the nature of climate, and of climate feedbacks, over the past 420,000 years. Marine records suggest that the amplitude of climate variability was smaller before that time, but such records are ...

CH4 and N2O fluctuations during the penultimate deglaciation

Jérôme Chappellaz

Gas is trapped in polar ice sheets at ∼50-120m below the surface and is therefore younger than the surrounding ice. Firn densification models are used to evaluate this ice age-gas age difference (Δage) in the past. However, such models need to be validated ...

Influence of Meteorological Conditions on Artificial Ice Reservoir (Icestupa) Evolution

Michael Lehning

Since 2014, mountain communities in Ladakh, India have been constructing dozens of Artificial Ice Reservoirs (AIRs) by spraying water through fountain systems every winter. The meltwater from these structures is crucial to meet irrigation water demands dur ...

The role of glaciers as sources of stream nutrients in a high mountain catchment

In the high mountain environments, streams often appear nutrient-limited. In glaciated catchments however, glacier meltwater acts as sources of nitrogen (N) and phosphorus (P) to downstream ecosystems, but research investigating t ...

Seascape Genomics of the Sugar Kelp Saccharina latissima along the North Eastern Atlantic Latitudinal Gradient

Chloé Christiane Laurence Jollivet, Stéphane Mauger

Temperature is one of the most important range-limiting factors for many seaweeds. Driven by the recent climatic changes, rapid northward shifts of species' distribution ranges can potentially modify the phylogeographic signature of Last Glacial Maximum. W ...

Snapshots of mean ocean temperature over the last 700,000 yr using noble gases in the EPICA Dome C ice core

Adrien Michel

Together with the latent heat stored in glacial ice sheets the ocean heat uptake carries the lion’s share of glacial/interglacial changes in the planetary heat content but little direct information on the global mean ocean temperature (MOT) is available to ...
