New constraints on the postglacial evolution of Lago Maggiore, Northern Italy

Journal of Quaternary Science, EarlyView.
ABSTRACT Lago Maggiore is situated in an overdeepened valley reach at the southern margin of the European Alps, and its thick sediment infill allows the reconstruction of the postglacial valley and lake evolution. We study here the sedimentary succession in the lower Ossola Valley, which is infilled by ~500 m of deposits. In a marginal position, a core

Fast response of fungal and prokaryotic communities to climate change manipulation in two contrasting tundra soils

Environmental Microbiome, 2019
Background Climate models predict substantial changes in temperature and precipitation patterns across Arctic regions, including increased winter precipitation as snow in the near future.

Climate‐modulated accumulation and erosion of sediments in the Rodderberg crater basin for the last 439 ka (East Eifel Volcanic Field, Germany)

Journal of Quaternary Science, EarlyView.
ABSTRACT Glacial/interglacial climate cycles since marine isotope stage (MIS) 12 influenced the discontinuous and 73 m‐long sediment record from the volcanic crater of Rodderberg in the East Eifel Volcanic Field, Germany. High‐resolution grain size and geochemical data have been valued by numerical dating techniques (radiocarbon and luminescence dating,

Brief communication: Testing a portable Bullard-type temperature lance confirms highly spatially heterogeneous sediment temperatures under shallow bodies of water in the Arctic [PDF]

The Cryosphere
The thermal regime in the sediment column below shallow bodies of water in Arctic permafrost controls benthic habitats and permafrost stability. We present a robust, portable device that measures detailed temperature–depth profiles of the near-surface ...

Cutting through the noise: What can habitat selection modeling teach us about caribou‐fire space use dynamics?

The Journal of Wildlife Management, EarlyView.
We synthesize the current knowledge regarding caribou habitat selection in relation to wildfires. Caribou responses to recent burns were generally weak and highly variable across subspecies or ecotypes, suggesting that post‐fire habitat selection is likely context‐dependent and the need for regionally adapted habitat management strategies.

Topographic and Climatic Determinants of Soil Organic Carbon Across Landscapes: A Meta‐Analysis

Land Degradation &Development, EarlyView.
ABSTRACT The soil is the greatest natural store of organic carbon, holding between 1500 to 1550 Pg C of organic carbon at the top 100 cm of the soil globally—roughly twice the carbon pool in the atmosphere. The spatial distribution of this stock is controlled by a complex chain of controls: topographic position regulates the hydrological redistribution,

Interplanetary frontiers: terraforming from an invasion science perspective

Oikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Competition and soil conditions limit the growth of High Arctic non‐native plants

Oikos, EarlyView.
Non‐native vascular plant species in the High Arctic are currently restricted mainly to settlements and other anthropogenically disturbed areas. The reasons for this remain unclear, but climate or dispersal do not appear to be the main limiting factors. Instead, biotic interactions combined with soil conditions may play important roles.

Stable isotopes of 18O and D in key components of water flows and the permafrost zone of Central Yakutia (Eastern Siberia)

Лëд и снег, 2019
On the basis of about 430 analyses, the 18O and D compositions (%o) of atmospheric precipitation, ground ice, surface and inter-permafrost underground waters of cryogenic-aeolian landscapes of Central Yakutia (Eastern Siberia) are discussed ...

Localizable Climate Change Education in Schools: Examining Impacts on Students' Environmental Science Agency

Science Education, EarlyView.
ABSTRACT As our daily lives become increasingly affected by climate change, school‐based science education plays a critical role in preparing students to understand and respond to this global crisis. This cohort controlled quasi‐experimental study conducted in the United States examined whether a localized climate change storyline unit compared to ...
