Hotspots on cold mountains: Hot flowers as pollinator refuges in mountain ecosystems

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mountain environments constrain the activity of ectothermic insects. Yet, fine‐scale thermal refuges can buffer these thermal constraints, helping insects remain active in cold conditions.

Calibrating an ice sheet model using high-dimensional binary spatial data

, 2016
Rapid retreat of ice in the Amundsen Sea sector of West Antarctica may cause drastic sea level rise, posing significant risks to populations in low-lying coastal regions.

Study of the impact of ice formation in leads upon the sea ice pack mass balance using a new frazil and grease ice parameterisation [PDF]

, 2015
Leads are cracks in sea ice that often form due to deformation. During winter months leads expose the ocean to the cold atmosphere resulting in supercooling and the formation of frazil ice crystals within the mixed layer.

Lichen bleaching as a response to long‐term experimental warming in the High Arctic

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Lichens are an important component of Arctic ecosystems. Studies have indicated a decline in the abundance of Arctic lichens during recent decades, which is often attributed to competitive pressure from vascular plants.

Antarctic ice sheet discharge driven by atmosphere-ocean feedbacks at the Last Glacial Termination [PDF]

, 2016
Reconstructing the dynamic response of the Antarctic ice sheets to warming during the Last Glacial Termination (LGT; 18,000–11,650 yrs ago) allows us to disentangle ice-climate feedbacks that are key to improving future projections.

Wind, waves, wing loading and the flight energetics of giant petrels

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Wind is a major factor driving seabird movement and energetics, the effects of which are modulated by morphology. Developments in tagging technology now make it possible to test predictions from aerodynamic theory about the effects of wind on flight performance in free ...

Application of HY-2B Satellite Data to Retrieve Snow Depth on Antarctic Sea Ice

Remote Sensing
Sea ice and its surface snow are crucial components of the energy cycle and mass balance between the atmosphere and ocean, serving as sensitive indicators of climate change.

Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

Integrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Extended seasonal prediction of Antarctic sea ice concentration using ANTSIC-UNet [PDF]

The Cryosphere
Antarctic sea ice has experienced rapid change in recent years, with the total sea ice extent abruptly decreasing after a period of gradual increase from the late 1970s until 2014.

What can lithics tell us about hominin technology's ‘primordial soup’? An origin of stone knapping via the emulation of Mother Nature

Archaeometry, EarlyView.
Abstract The use of stone hammers to produce sharp stone flakes—knapping—is thought to represent a significant stage in hominin technological evolution because it facilitated the exploitation of novel resources, including meat obtained from medium‐to‐large‐sized vertebrates. The invention of knapping may have occurred via an additive (i.e., cumulative)
