Reactions of ground-nesting marine birds to human disturbance in the Canadian Arctic

open access: yesArctic Science, 2016
I studied the reactions of five ground-nesting marine bird species (Arctic tern (Sterna paradisaea), Sabine’s gull (Xema sabini), common eider (Somateria mollissima), long-tailed duck (Clangula hyemalis), and Ross’ gull (Rhodostethia rosea)) breeding in ...

Semi-Supervised Fine-Grained Image Categorization Using Transfer Learning With Hierarchical Multi-Scale Adversarial Networks

open access: yesIEEE Access, 2019
Fine-grained image categorization is still a challenging computer vision problem in recent years. Most of existing methods highly rely on massive labeled data which are scarce in many real world applications.

Using a live‐streaming webcam to assess the behavioural responses of waterbirds to changes in the density of swans Cygnus spp.

open access: yesWildlife Biology, EarlyView.
Wildlife research has benefitted from the development of new methods that allow data to be collected remotely, with less disturbance to focal animals. The proliferation of livestreaming webcams, for example, those used by nature reserves for public engagement purposes, have offered new possibilities for the study of wildlife behaviour.

Bubble Formation Control: Fabrication of Centimeter‐Sized Tissue‐Like Constructs by Catalase‐Coated Oxygen‐Releasing Hydrogel

open access: yesAdvanced Materials, Volume 38, Issue 47, 21 August 2026.
Oxygen‐releasing hydrogels are widely used to support cell survival in 3D cultures and to promote wound healing. However, incorporating catalase to convert H2O2 into O2 often generates additional oxygen bubbles, leading to material instability which rarely addressed.

The influence of rivers on seabird foraging ecology

open access: yesBiological Reviews, Volume 101, Issue 4, Page 1704-1734, August 2026.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Ecological implications and lessons from high pathogenicity avian influenza H5N1 2.3.4.4b in Antarctica

open access: yesEcological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
HPAI H5N1 was confirmed in 22 South Polar Skuas and one Kelp Gull on Dismal and Horseshoe Islands, Marguerite Bay, Western Antarctic Peninsula in early 2025, with high mortalities consistent with global trends. Rapid antigen tests showed 90% agreement with rRT‐PCR, supporting their utility for early detection in remote environments.

Conserving the World's Specialist Riverine Birds

open access: yesWIREs Water, Volume 13, Issue 4, July/August 2026.
Specialist riverine birds constitute a diverse bird group globally, highly adapted to rivers and streams. They are at risk from multiple threats to rivers, riparian zones and river catchments including impoundment, hydropower and abstraction; land‐use changes including urbanization and agricultural intensification; traditional and emerging pollutants ...
