Storm events will simultaneously reduce foraging opportunities and affect movements of Red Knots (Calidris canutus) in the intertidal Wadden Sea

open access: yesIbis, EarlyView.
Intertidal systems provide important wintering areas for migratory shorebirds, where they can both forage and roost. In the light of climate change, extreme wind speeds are predicted to occur more frequently in northwestern Europe and pose a threat to shorebirds.

The influence of a cooling water system on waterbird habitat use in a coastal environment

open access: yesIbis, EarlyView.
This study investigated the impact of a cooling water system at a nuclear power plant in northern Europe on coastal waterbird habitat use. In winter, the cooling water system provided preferential areas for waterbirds with warm productive waters, and, more importantly, with ice‐free areas.

First Report of the Malacosporean Parasite Tetracapsuloides bryosalmonae in the Faroe Islands Reveals Widespread Distribution and High Prevalence in Brown Trout

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT The myxozoan endoparasite Tetracapsuloides bryosalmonae (Tb), the causative agent of proliferative kidney disease (PKD) in salmonids, has predominantly been reported in temperate regions of continental Europe and North America. Here, we present the first record of Tb in the Faroe Islands, extending the known northern distribution of the ...

Transmission Dynamics of Highly Pathogenic Avian Influenza at Lake Constance (Europe) During the Outbreak of Winter 2005-2006 [PDF]

open access: yes, 2018
Highly pathogenic avian influenza virus (HPAI) H5N1 poses a serious threat to domestic animals. Despite the large number of studies on influenza A virus in waterbirds, little is still known about the transmission dynamics, including prevalence, behavior,

Fit for purpose? Analysis of the relationship between skull, beak shape and feeding ecology in Psittaciformes

open access: yesJournal of Anatomy, EarlyView.
Psittaciformes exhibit high levels of morphological diversity, particularly in skull and beak structure, previously linked to diet and body size. Although there were some levels of significance between diet and beak shape, body mass was a much stronger co‐variate. Diet is not determining beak shape within the clade.

Wintering Barnacle Geese Exhibit an Increased Behavioural Drive for Sleep After Sleep Deprivation Without a Clear EEG‐Based Sleep Rebound

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Sleep is essential for normal physiological functioning, and sleep deprivation is typically compensated by increasing subsequent sleep duration and/or intensity. However, a recent study showed that barnacle geese (Branta leucopsis) exhibit seasonal variation in sleep homeostasis, with full recovery of sleep after sleep deprivation in summer ...
