Fish prey of the Antarctic fur seal Arctocephalus gazella at South Georgia [PDF]
A small collection of otoliths was obtained from scatsof sub-adult male Antarctic fur seals Arctocephalus gazella at Bird Island, South Georgia. A reference collection of otoliths from South Georgia fish was used to identify the material and to derive ...

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

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

ABSTRACT Recovering ancient DNA from environmental samples is transforming the way we understand historical ecosystems. While high‐throughput sequencing of the total DNA in environmental samples (shotgun metagenomic sequencing) reveals the taxonomic contents of these samples, the genetic signals of some taxa (e.g., eukaryotes) can be weak compared to ...

Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.

Three‐Dimensional Correlated Random Walks for Animal Movement and Habitat Selection
Step selection functions (SSFs) are popular models of animal movement and habitat selection. However, SSFs have only been formulated in two dimensions, which limits our understanding of species that swim or fly. In this paper, we present fully three‐dimensional SSFs, suitable for positioning data collected as easting, northing, and altitude/depth.
