摘要
2010年7月，在西北地区维多利亚岛对北美驯鹿(Rangifer tarandus pearyi)和麝牛(Ovibus moschatus)进行了调查。成年驯鹿种群估计值为150±104(95%可信区间[CI])，与2005年估计值66±61 (P < 0.05)无显著差异(P < 0.05)。在研究区内估计有430±214只成年海豚联合驯鹿(R. t. groenlandicus x pearyi)。然而，这些驯鹿只占海豚联盟种群的一小部分。成年麝牛种群估计值为11 442±1637 (95% CI)，与2005年估计值12 062±2156无显著差异(P < 0.05)。
Peary caribou (Rangifer tarandus pearyi) and muskoxen (Ovibos moschatus) on northwest Victoria Island, Northwest Territories
An aerial population survey of Peary caribou (Rangifer tarandus pearyi) and muskoxen (Ovibus moschatus) on Victoria Island, Northwest Territories, was conducted in July 2010. The population estimate of adult Peary caribou was 150 ± 104 (95% Confidence Interval [CI]) was not significantly different than the 2005 estimate of 66 ± 61 (P < 0.05). There was also an estimate of 430 ± 214 (95% CI) adult Dolphin-Union caribou (R. t. groenlandicus x pearyi) in the study area. However, these caribou represent only a small portion of the Dolphin-Union herd. The population estimate of 11 442 ± 1637 (95% CI) adult muskoxen is not significantly different than the 2005 estimate of 12 062 ± 2156 (P < 0.05).
