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 ...

Clade‐wide morphological and functional variation of the sauropsid columella

The Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

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.

The influence of rivers on seabird foraging ecology

Biological Reviews, EarlyView.
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 ...

Extent, characteristics and policy applications of Key Biodiversity Areas

Biological Reviews, EarlyView.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy
