Seals gamble with their pups' futures
Date:11/20/2012

Some grey seal mums adopt risky tactics when it comes to the future of their young, a strategy that can give their pup a real advantage, according to scientists.

Researchers from Durham University, UK, and the University of St Andrews, looking at grey seal colonies in Scotland, found that some seal mothers are flexible in the parenting style they adopt and 'gamble' on the outcome of their actions, whilst other play it safe and steady.

The study is the first to demonstrate how variation in personality traits in large marine mammals in the wild can persist, rather than a single, successful, personality type dominating the population.

The research shows that some seal mothers have a very fixed approach to looking after their pups, and tend to behave in a similar fashion whatever the local conditions on the breeding colony are; whether they are in a crowded and busy location, or in a less disturbed situation. These mums tend to achieve average success in terms of their pups' weight gain (crucial to the future survival of the pup), so that, by-and-large, they generally do well. These mums seem to have a 'play it safe' approach to life.

Some seal mothers have a very different approach. These mums are more flexible and try to adjust their mothering behaviour according to the local conditions. In potentially unpredictable situations, this can be risky; sometimes they get it right and their pups fare very well, but other times they might get it wrong and their pups do rather badly.

The findings, published in the journal PLoS One, show that individual animals can differ markedly in their ability to adjust their behaviour to their local environmental conditions and that large variations in behavioural strategies can persist within a species.

According to the researchers, the results for both extremes of personality show how different types can be maintained by selection. This retains behavioural diversity wit
