Inter-annual growth of Arctic charr (Salvelinus alpinus, L.) in relation to climate variation
Abstract Background Major changes in climate have been observed in the Arctic and climate models predict further amplification of the enhanced greenhouse effect at high-latitudes leading to increased warming. We propose that warming in the Arctic may affect the annual growth conditions of the cold a...
