Loss or redistribution? A better way of estimating regional changes in animal distribution and numbers caused by increased human activities Open
A differentiated understanding of how regional human activities affect the spatial distribution and numbers of animals within specific areas of interest is of great ecological importance. Estimating these effects from empirical data is cha…

Migratory pathways and winter destinations of Northern Gannets breeding at Helgoland (North Sea): known patterns and increasing importance of the Baltic Sea Open
We analysed the migratory behaviour of adult Northern Gannets ( Morus bassanus ) breeding at Helgoland in the North Sea, based on data obtained from geolocation devices in the non-breeding season 2016–2017. Birds moved east and south-west …

Cumulative effects of offshore wind farms on common guillemots (Uria aalge) in the southern North Sea - climate versus biodiversity? Open
Governments are under increasing pressure to reduce greenhouse gas emissions, and large-scale wind farms are being developed in marine environments worldwide. However, top predators are strongly affected by environmental change and anthrop…

Atlantor, a new generic name for Barbus reinii Günther, 1874 from Morocco(Teleostei: Cyprinidae) Open
Atlantor, new genus, is proposed for Barbus reinii from the Atlantic basin in Morocco. The sole species of the genus is clearly separated from related genera based on its phylogenetic position, and from Carasobarbus, Mesopotamichthys and P…

An Integrated Framework to Estimate Seabird Population Numbers and Trends Open
Generating trend and population estimates from bird count data is challenging and a variety of factors have to be taken into account. We present an integrative statistical approach for estimating population numbers and trends for seabirds …

A Ship Traffic Disturbance Vulnerability Index for Northwest European Seabirds as a Tool for Marine Spatial Planning Open
Ship traffic in Northwestern European seas is intense and continuing to increase, posing a threat to vulnerable seabird species as a result of disturbance. However, information on species-specific effects of ship traffic on seabirds at sea…
