Oceanic regions shape the composition of the Antarctic plastisphere

open access: yesCommunications Earth & Environment
Abstract Antarctica, once considered pristine, is increasingly threatened by plastic pollution, with debris found in its waters, sediments, sea ice, and biota. Here, we provide a comprehensive molecular survey of both prokaryotic and eukaryotic diversity on plastics around the Antarctic Peninsula, addressing a gap in existing research.

Integrating migratory connectivity data into the conservation of Australian sharks and rays

open access: yesConservation Biology, EarlyView.
Abstract Understanding migratory connectivity is important for conserving highly mobile marine species facing escalating threats. Establishing baseline information on migratory connectivity is necessary for identifying species and regions requiring transboundary cooperation for their conservation.

To release or not to release? Understanding sawfish release behavior in a global south complex fishery

open access: yesConservation Science and Practice, EarlyView.
This demonstrates the gap between existing top‐down laws and strategies (Current Approach) and the barriers fishers face while proposing an alternative pathway (Proposed Approach) based on collaboration, capacity building, and addressing socio‐economic factors.

Triple Oxygen Isotope Compositions of Isotopic Reference Waters: Implications for VSMOW‐Scale and VSMOW–SLAP‐Scale Δ′17O Calibration

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Triple oxygen isotope ratios of two primary (VSMOW, SLAP) and twelve secondary water isotopic reference materials were precisely measured using BrF5 fluorination‐IRMS. The measured Δ'17OVSMOW value for SLAP (34 ± 6 per meg) demonstrates that VSMOW‐SLAP normalisation ensures interlaboratory comparability, but introduces systematic offsets for

Plausible Last Interglacial Antarctic Ice Sheet Changes Do Not Fully Explain Antarctic Ice Core Water Isotope Records

open access: yesGeophysical Research Letters
Antarctic ice cores can help determine ice mass loss from the Antarctic Ice Sheet (AIS) during past warm periods. We compile Last Interglacial (LIG) δ18O measurements from eight Antarctic cores and compare these to new isotope‐enabled LIG simulations ...

Seasonal variation in preen gland secretions of Tristram's Storm Petrel (Hydrobates tristrami)

open access: yesIbis, EarlyView.
Preen gland secretions are known to vary depending on sex, season and species and are thought to play essential roles in avian life history. However, their chemical composition and functions remain largely unclear in Procellariiform seabirds with well‐developed olfactory senses. Storm petrels, known for their distinctive body odour, may use preen gland

A rapid shift in migration schedule of an Austral shorebird is linked to a changing southern climate oscillation

open access: yesIbis, EarlyView.
Global climate change is reshaping the schedules and routes of migratory birds, which can disrupt annual cycles, ecological interactions and the fitness trade‐offs of migrating or staying resident. In particular, climate change has led to advances in arrival at the breeding grounds and to shifts in the timing of post‐breeding migration, whereby both ...
