44、m led by Fisheries and Oceans Canada measured boldness responses in the female seals when defending their young. “During the breeding season,we saw that females tend to behave consistently,not only between years,but also within the lactation period(哺乳期) of a given year,” explained Bubac,lead author
45、and PhD student in the Department of Biological Sciences studying with wildlife geneticist David Coltman.“This provides an example of animal personality,with consistent individual differences observed over time.” Bubac also examined how reproductive success is related to a seals boldness or shyness.
46、Grey seals nurse for 16 to 18 days,so mother seals have a very short window to get baby seals as fat as they can.During this time,baby seals triple(增至三倍) in body mass.Body mass is a good predictor of reproductive success because it indicates the puppies chances of survival.“On average,we found that
47、bolder females stop feeding those that are two kilograms heavier,compared with the shyest females,improving their chances of surviving the first year of life,” said Bubac. These results present some very interesting biological questions,explained Coltman,professor of biology.“This research shows tha
