in this study, the cdna growth hormone (cgh) of the belugasturgeon (husohuso) and russian sturgeon (acipensergueldenstaedtii) were cloned and sequenced, and phylogenetic relationships were examined using nucleic acid and amino acid sequences. the nucleotide sequence of the beluga gh has an open reading frame of 645 nucleotides encoding a protein 214 amino acid residues. the signal peptide cleav...

Beluga whales (Delphinapterus leucas) are an integral part of many Arctic Indigenous cultures and contribute to food security for communities from Greenland, across northern Canada Alaska Chukotka, Russia. Although the harvesting stewardship practices peoples vary among regions have shifted adapted over time, central principles respect beluga sharing harvest remained steadfast. In addition intr...

Appropriate marine–terrestrial reservoir offset (ΔR) values are essential for accurate calibration of marine radiocarbon dates. However, ΔR only valid the specific curve that their calculation is based on. Here, we present revised Marine20 from Arctic North America, on previously published 14C dates pre-bomb live-collected molluscs (n = 124) and cetaceans (beluga whales; tooth dentine; n 12), b...
