Assessing breeding duck population trends relative to anthropogenic disturbances across the boreal plains of Canada, 1960-2007

Avian Conservation and Ecology, 2020
Impacts of anthropogenic disturbance on duck populations in the boreal forest is largely unknown but hypothesized to negatively influence abundance through top-down and bottom-up processes.

Using Breeding Bird Survey and eBird data to improve marsh bird monitoring abundance indices and trends

Avian Conservation and Ecology, 2023
The elusive nature of many marsh-breeding birds presents a challenge for effective population monitoring. The Great Lakes Marsh Monitoring Program (GLMMP), delivered by Birds Canada, addressed these challenges by concentrating survey efforts in marsh ...

Comparison of Sertoli cells in duck testes pre- and post-sexual maturation

Poultry Science
To investigate the role of Sertoli cells in duck testicular development and maturation, we conducted single-cell RNA sequencing on testes from immature (IMT) and mature (MT) ducks.

Effects of habitat conditions in created wetlands on sustaining wintering waterfowl in riverine plains, Nakdong River, South Korea

Journal of Ecology and Environment, 2015
The landscape setting of a habitat strongly influences the distribution, abundance, and species composition of waterfowl. Thus, habitat assessment is very important to understand the habitat characteristics that sustain waterfowl

Duck Orbivirus and Egg Production: A Newly Identified Duck Orbivirus Is the Etiological Agent of Egg Production Decline in Chinese Breeder Ducks

Animal Research and One Health, EarlyView.
Field samples from breeder duck farms with egg‐production decline were subjected to viral detection, genome sequencing, and virus isolation. Experimental infection demonstrated that duck orbivirus (DORV) causes a significant and persistent reduction in egg production in breeder ducks.

OPN5 Regulating Mechanism of Follicle Development Through the TSH-DIO2/DIO3 Pathway in Mountain Ducks Under Different Photoperiods

Frontiers in Physiology, 2022
: Photoperiod is an important environmental factor that influence seasonal reproduction behavior in bird. Birds translates photoperiodic information into neuroendocrine signals through deep brain photoreceptors (DBPs).

Disentangling functional spaces: a multidimensional framework for ecology and conservation

Ecography, EarlyView.
Trait‐based ecology often relies on a single functional space, where diverse traits are combined into one multivariate framework. While convenient, this approach risks masking ecological strategies because variance is often dominated by a few traits, such as body size.
