Whales have several important ecological functions as top predators in marine ecosystems and may also serve as sentinels of anthropogenic activities that drive ecosystem shifts. It is therefore important to have efficient methods to monitor the spatiotemporal presence of different whale species in the vast ocean realm. Traditionally, visual observations from research vessels have been the method of ...

An increasing anthropogenic stressor in marine ecosystems is artificial light at night. Especially in the Arctic where exposure is increased by extended periods of darkness during the polar night. This study focuses on underwater artificial light used in occasional situations such as scientific sampling and measuring, stock assessment or lights from navigating boats. This study examines the effects ...

Altruistic behaviour is a type of prosocial behaviour which is costly to the actor but beneficial to the recipient. It can, in children, be influenced by numerous factors, including parental political orientation, parental religiousness, and the child's age and gender. This cross-sectional research investigates these parental influences and individual factors on altruistic behaviour of children in ...

<ol> <li>Population dynamics of specialist predators are tightly linked to their main prey and can in simple food webs lead to complex predator–prey interactions (e.g. predator–prey cycles). However, the strength of these interactions may be affected by the availability of alternative prey if it appears in high numbers and the predator diet is sufficiently flexible.</li> <li>A prominent example of ...

Motivation - Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, ...

Rapid climate change significantly impacts high-latitude freshwater ecosystems, altering thermal regimes and ecological dynamics. This study examines the lakes Vaggatem and Skrukkebukta in Pasvik in Northern Norway, where recent decades have seen average increases in surface water temperatures of 0.45°C per decade, accompanied by a modelled 0.07°C decadal rise in hypolimnetic water temperatures, ...

This review examines the evolution and findings of Norway's offshore environmental monitoring (OEM) program over the past five decades. The program targets soft sediments, water column organisms, and deep-water epifauna across the Norwegian Continental Shelf (NCS) to assess the impacts of offshore oil and gas activities. The program is required by Norwegian authorities and financed by oil and gas ...

I løpet av de siste tiårene har flere fagmiljø i høyere utdanning i Norge utviklet og etablert praksisemner for studenter innen disiplinfagene biologi og geologi, samt det tverrfaglige studiet fiskeri og havbruksvitenskap. I denne workshopen vil vi gjennomføre en interaktiv “Jigsaw aktivitet” for å presentere og diskutere erfaringer og forskningsresultater fra implementeringen av disse praksisemnene ...

Salinity is a major factor influencing sea ice algal activity in experimental settings and in nature. Decreases in salinity, occurring during the ice melting procedure, impact measurements of primary productivity and photophysiology of sea ice algae via ¹⁴C-based incubations. Sea ice algae also face low salinity stress in their natural environments, for instance, due to seasonal melting ...

Speciation research—the scientific field focused on understanding the origin and diversity of species—has a long and complex history. While relevant to one another, the specific goals and activities of speciation researchers are highly diverse, and scattered across a collection of different perspectives. Thus, our understanding of speciation will benefit from efforts to bridge scientific findings ...
