The influence of rivers on seabird foraging ecology. [PDF]
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 ...

Holding a wing horizontal: Roles for muscles of the pectoral girdle other than the main two flight muscles. [PDF]
This report explores which muscles of the pectoral girdle are employed to allow birds to hold their wings horizontally with a level aerofoil surface during a glide. Abstract Whilst many birds glide briefly with wings held horizontally, some species maintain this posture for extended periods during soaring.

Management of Double-Crested Cormorants to Improve Sport Fisheries in Michigan: Three Case Studies
Impacts of double-crested cormorants (Phalacrocorax auritus) to fisheries have been documented, but evaluation of the process and outcomes of cormorant management to reduce impacts on fisheries is lacking. We provide a synthesis of adaptive management of

Modeling the Economic Impacts of Double-Crested Cormorant Damage to a Recreational Fishery
The double-crested cormorant (Phalacrocorax auritus) has undergone a significant range expansion in the Great Lakes area of the United States since the 1970s, negatively impacting native fish populations and sport fisheries.

Assessing Biodiversity at Eastern Oyster (<i>Crassostrea virginica</i>) Aquaculture and Reef Sites Utilizing Real-Time Monitoring and Environmental DNA in Rehoboth Bay, Delaware, USA. [PDF]
Eastern oysters (Crassostrea virginica) are a keystone species and vital to the commercial shellfish industry, acting as environmental engineers that enhance biodiversity. To study their impact, real‐time monitoring and Environmental DNA analysis were conducted at various sites in Rehoboth Bay, Delaware and 23 species were identified, with Spot ...

Effects of Aquaculture on Migration and Movement Patterns of Double-Crested Cormorants
We analyzed 10,620 recovery records for double-crested cormorants (Phalacrocorax auritus) banded as nestlings from 1923 to 2006 to determine the population’s age structure, migration routes, dispersal patterns, and the possible influence of the expansion
