Studies of captive gray wolves () showed seasonal cycles in hematologic values and female body mass. We used a remotely controlled recapture collar to determine whether nine female and five male free-ranging wolves handled four to 17 times in NE Minnesota, US showed similar cycles. Hematocrit, hemoglobin, red blood cell count, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and body mass increased from summer toward a winter peak and then decreased again toward summer. Several hematologic values differed considerably from those of captive wolves, and the ranges in free-ranging wolves were much greater than those of captives.
对圈养灰狼的研究表明，其血液学值和雌性体重存在季节性变化。我们使用遥控重捕项圈来确定美国明尼苏达州东北部的 9 只雌性和 5 只雄性自由放养狼是否表现出类似的周期，这些狼被重捕了 4 到 17 次。血球比容、血红蛋白、红细胞计数、平均红细胞血红蛋白、平均红细胞血红蛋白浓度和体重从夏季增加到冬季高峰，然后再次下降到夏季。一些血液学值与圈养狼有很大的不同，而且自由放养狼的范围比圈养狼大得多。
