Documenting species occurrence and distribution patterns is fundamental for effective conservation strategies, particularly for endangered species facing various threats. Killer whales ( Orcinus orca ) are distributed worldwide, yet some populations, such as the critically endangered Strait of Gibraltar subpopulation, lack comprehensive distribution data. This study focuses on documenting the occurrence of Strait of Gibraltar...

Climate change is projected to cause alterations in northern coastal systems, including humification and intensified nutrient loads, which can lead to ecosystem imbalances and establishment of new bacterial species. Several potential pathogens, such as different species of Legionella , hide in the environment between infections, some by living inside protozoan host cells. Knowledge about the occurrence of Legionella in natural...

This paper describes the new developments of the Ship Traffic Emission Assessment Model (STEAM) which enable the modelling of pollutant discharges to water from ships. These include nutrients from black/grey water discharges as well as from food waste. Further, the modelling of contaminants in ballast, black, grey and scrubber water, bilge discharges, and stern tube oil leaks are also described as well as releases of contamina...

Female and immature sperm whales form stable social units in tropical to subtropical waters. One such area is the Azores archipelago, where details of their year‐round occurrence and social organization are not well known. We used year‐round sightings data collected from whale watching vessels to assess sperm whale occurrence and social structure off São Miguel Island, Azores from 2010 to 2017. Individuals were photo‐identifie...
