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.

Morphological and Morphometric Characterisation of Selected Camarodont Sea Urchin (Echinoidea: Camarodonta) Pedicellariae (Paracentrotus lividus, Psammechinus miliaris and Echinus esculentus)

Acta Zoologica, EarlyView.
ABSTRACT Pedicellariae are small appendages on the surface of the echinoid test, involved in defence, cleaning, and locomotion. Pedicellariae in three species of camarodont sea urchins common in UK waters (Paracentrotus lividus [Lamarck, 1816], Psammechinus miliaris [P.L.S Müller, 1771] and Echinus esculentus [Linnaeus, 1758]) are the focus of this ...

Early to Mid‐Holocene molluscan community dynamics in Billefjorden, central Svalbard: the interplay of local geomorphology and regional climate

Boreas, EarlyView.
The postglacial evolution of High Arctic coastal environments is recorded in the rich fossiliferous archives of raised marine terraces. This study employs a multi‐proxy approach combining molluscan community analysis, taphonomy and sedimentology to reconstruct the Early to Mid‐Holocene environmental dynamics of the Mimerdalen embayment in the ...
