Effects of submerged aquatic vegetation and water quality on waterfowl abundance by foraging guild

Ecological Solutions and Evidence, 2022
Back Bay, Virginia, has been documented as an important foraging area for waterfowl since at least the mid‐1800s. Expansive submerged plant beds historically supported diverse assemblages of non‐breeding waterfowl; however, coastal development and other ...

Tracing origins of waterfowl using the Saskatchewan River Delta: Incorporating stable isotope approaches in continent-wide waterfowl management and conservation

, 2017
Understanding the catchment areas of key stopover sites for migratory birds is important for their management and conservation. The Saskatchewan River Delta (SRD) in central Canada is North America's largest inland delta and an important spring and fall ...

A Functional Flows Framework for the Terminal Great Salt Lake Basin: Can We Have Our Lake and Drink It Too?

River Research and Applications, EarlyView.
ABSTRACT Terminal basins provide unique aquatic environments that are often highly sensitive to streamflow contributions, making them a focal point for environmental water management. However, the water needs for terminal lake, wetland, and river ecosystems, and how they relate, remain a fundamental knowledge gap that constrains our ability to ...

Polysaccharides of Atractylodes macrocephala Koidz alleviate bursa of Fabricius involution in Magang geese by inhibiting the Wnt signaling pathway

Poultry Science
Involution of the bursa of Fabricius (BF) with increasing age in avian species leads to decreases in lymphocyte counts and pathogen recognition, thereby compromising immune function and increasing susceptibility to infections.

Accounting for animal movement during aerial imaging surveys

Remote Sensing in Ecology and Conservation, EarlyView.
Animals are not stationary during aerial surveys; if their movements are related to the movement of the aerial platform, then bias can be introduced into subsequent population count estimates. We sought to establish a framework for assessing the impacts of animal movement on count error and platform bias by comparing aggregated counts and relative ...

2011-2012 Illinois Waterfowl Hunter Survey: Behavior, Satisfaction, and Video-Watching of Waterfowl Hunters [PDF]

, 2012
A total of 2,503 (52%) Illinois waterfowl hunters responded to the 2011-2012Illinois Waterfowl Hunter Survey. Hunters reported spending 1,147,037 days afield, an increase of 16% from the 985,075days devoted during the 2010-2011license year.

Fusion or Confusion? Assessing the Impact of Visible‐Thermal Image Fusion for Automated Wildlife Detection

Remote Sensing in Ecology and Conservation, EarlyView.
This study evaluates the performances of synchronous aerial visible (VIS) and thermal infrared (TIR) imagery for detecting great blue heron (Ardea herodias) nests and individuals using a YOLO11n model. VIS and TIR images were automatically aligned using deep learning, and both early and late fusion approaches were tested.

Determinants of highly pathogenic avian influenza spread during bird migrationDeterminants of highly pathogenic avian influenza spread during bird migration [PDF]

Royal Society Open Science
Migratory waterfowl are central to the global spread of the Goose/Guangdong lineage of H5 highly pathogenic avian influenza (HPAI), yet the parameters and processes shaping their role remain poorly understood, with evidence scattered across studies ...

Remote Sensing‐Based Identification of Habitat Loss for Herbivorous Waterbirds Driven by Wetland Inundation Alterations

Remote Sensing in Ecology and Conservation, EarlyView.
We present a deep learning framework integrating remote sensing and SHAP interpretation to map 22‐year habitat dynamics of herbivorous waterbirds in Dongting Lake. Results show nearly 50% habitat loss, driven primarily by hydrological recession timing rather than static inundation extent.
