TL;DR: The selection pressures on growth and the resultant evolution of growth from a mechanistic viewpoint are explored and the prevailing expectation that fishing-induced evolution should always lead to slower growth is challenged.

TL;DR: In this paper, the authors review current knowledge regarding the importance of these areas for these animals and reflect upon the processes that create these apparent “hotspots”, which is known for a long time that these glacier front areas are important feeding areas for seabirds and marine mammals.

TL;DR: In this paper, the effects of an extreme warm spell and heavy rain-on-snow (ROS) event that occurred in High Arctic Svalbard in January-February 2012, during the polar night, were investigated.

TL;DR: It is argued that even during the polar night, DVM is regulated by diel variations in solar and lunar illumination, which are at intensities far below the threshold of human perception, which suggests that the biologically mediated vertical flux of carbon will increase if there is a continued retreat of the Arctic winter sea ice cover.

TL;DR: Several recent lines of evidence indicate that the polar night is key to understanding Arctic marine ecosystems, and it appears that many organisms may exhibit endogenous rhythms that trigger fitness-maximizing activities in the absence of light-based cues.
