Critical constraints to ecological buffering in a rapidly changing Arctic: A long‐term seabird study

Journal of Animal Ecology, EarlyView.
Drawing on two decades of research in East Greenland, this study shows that little auks, key seabird indicators of Arctic ecosystem health, can adapt to rapid environmental change through behavioural flexibility. However, increasing storms and mercury pollution are pushing resilience to its limits, providing an early warning of broader Arctic ...

Life Under the Snow: Camera Trap Videos Capture Year‐Round Lemming Activity and Behavior

Integrative Zoology, EarlyView.
We developed an automated camera system capable of recording year‐round videos of lemmings beneath the snow in the High Arctic. We demonstrate the potential of this system to document lemming activity and behaviors. Our results show that it effectively monitors lemming relative abundance with temporal precision unmatched by other methods.

Sari‐Sari: Filipino Grocery Stores and Transnational Migrant Food Networks in Hong Kong

Asia Pacific Viewpoint, EarlyView.
ABSTRACT Despite being one of Hong Kong's largest ethnic minorities, Filipino migrants have a significant albeit understated impact on its foodscape. Hong Kong has a reputation for being a culinary melting pot, yet Philippine food has only recently gained popularity and visibility among its broader population.

The Materiality of the Cloggs Cave Rockshelter's Painting, GunaiKurnai Country (East Gipplsland), Southeastern Australia

Archaeometry, EarlyView.
ABSTRACT The materiality of the white pigment motif at the Cloggs Cave rockshelter, near Buchan in GunaiKurnai Country (southeastern Australia), contains details about the cultural and environmental contexts in which the art was created and preserved. Here, we (1) present physicochemical analyses of the pigment composition; (2) explore implications for

The last glacial cycle in western Norway—extensive MIS 5d glaciation, multiple glacial advances and LGM glacial advance phases

Boreas, EarlyView.
Raised marine MIS 5c sediments evidence extensive preceding (5d) glaciation in western Norway. This is the first out of five (or six) major Weichselian glacier advances that seem to correspond to North Atlantic sea surface cooling periods. Till beds capping the marine sediments show stages of pre‐LGM advance and subsequent retreat.
