Local movements and site-tenacity of minke whale in Iceland in relation to feeding and a northward distribution shift
Population dynamics, movement patterns and migratory routes of common minke whales (Balaenoptera acutorostrata) in the North Atlantic are not yet fully understood. Small-scale movements of minke whales within Skjálfandi Bay, Iceland, were analysed and discussed in relation to population dynamics in...

Population dynamics, movement patterns and migratory routes of common minke whales (Balaenoptera acutorostrata) in the North Atlantic are not yet fully understood. Small-scale movements of minke whales within Skjálfandi Bay, Iceland, were analysed and discussed in relation to population dynamics in the North Atlantic. Local distribution and abundance of minke whales were investigated on both individual and population basis. Data were obtained through continuous sighting surveys from 2005 to 2018, conducted by trained volunteers using whale watching vessels as opportunistic research platforms. Variations in abundance might reflect a species distribution shift to higher latitudes. Competition for prey and the general movement of several species from different taxonomic groups support a potential range shift. For the first time, habitat use of minke whales in Skjálfandi Bay was revealed through spatial analysis, as well as small-scale site-tenacity, proven through modelling of distances between individual and random relocations. To improve the status of the declining minke whale population around Iceland we suggest recognition of separate minke whale management units using different areas. Additionally, we encourage the protection of different feeding grounds which will reduce local anthropogenic stressors and likely improve minke whales' coping with climate change and shifts in prey. |
