3. Gannets and Cormorants (Sulidae and Phalacrocoracidae)

, 2023
With key information linked to thematic maps, this section evaluates the climate change vulnerability of three species of gannets and cormorants (Sulidae and Phalacrocoracidae) – Northern Gannet, European Shag, and Great Cormorant – in the North-East Atlantic. The assessments for every species cover three categories each: the exposure, or the magnitude

Phylogenetic relationship between Contracaecum spp. (Nematoda, Anisakidae) parasitizing cormorants (Aves, Phalacrocoracidae) from Argentina

Parasitology Research, 2023
Abstract Anisakidae nematodes have a wide host and geographic distribution. Species of the genus Contracaecum parasitize aquatic organisms such as piscivorous birds and mammals as their definitive hosts. Several Contracaecum species have been reported parasitizing Phalacrocoracidae in South America.

Into the Wild: Farm‐Derived Energy and Nutrients Enter Marine Food Webs With Carrying Capacity Implications for Aquaculture Management

Reviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Marine aquaculture is expanding globally, yet its interactions with surrounding ecosystems remain complex and insufficiently understood. This study reviews the fluxes of energy and nutrients from three major aquaculture systems: finfish cages, suspended bivalves, and seaweed farms and considers their implications for ecosystem functioning and ...

Swimming modes affect dive durations in diving birds

Journal of Avian Biology, Volume 2026, Issue 2, March 2026.
Dive duration and body mass are positively correlated across air‐breathing vertebrate species, but other factors affecting dive duration are inadequately studied. Here, we examined the effect of a previously overlooked factor, swimming mode, using phylogenetically informed statistics with data on the diving capabilities of 53 species of avian divers ...

Effects of hunting on waterbird numbers in Mediterranean coastal wetlands in France: the case of the Hérault department

Wildlife Biology, Volume 2026, Issue 2, March 2026.
Waterfowl hunting plays a complex role in the conservation of waterbird populations. While hunting can provide conservation benefits, excessive or unregulated hunting may threaten waterbird populations, particularly for species with declining numbers or high sensitivity to human disturbances.
