Hormones can adapt themselves to a new environment, new study says

It is fascinating for every biologist to learn about animals’ behavior at different times and intervals during its life. Each species of animal will have different behavioral tactics to survive in the world. Animal behavior is influenced by various factors such as temperature, food availability, colony size, etc. Scientists try to understand the mechanism of adaptation of animals to a newer environment, and they have found that the hormonal status can probably impact on the behavior of animals.

A behavioral biologist at Munster University has given an idea that the males, even after finishing their adolescent stage, can still adapt their hormone systems to change in their social environment. They have done a trial with the guinea pigs where male guinea pigs are raised with a female during the adolescent period. Later, they observed that the male showed aggressiveness towards the unfamiliar males. This has hinted that the social environment during adolescence might play a role in how individuals behave in later life.

The study includes the male guinea pig growing in different social housing conditions such as it either grows in large mixed-sex colonies or in pairs with a female. Once the male growing in mixed-sex colony attains the adulthood stage, it is transferred to pair housing with an unfamiliar female, thereby inducing a different social niche. The males who grow in pairs with a female, although their niche isn’t changed, the female has changed. The researchers want to know how the males react in the new social induced environment. They also estimated the concentration of testosterone and cortisol in view of their findings.

After one month of transfer to pair housing with an unfamiliar female, there was a reduction in their testosterone levels and an increase in their cortisol responsiveness. Also, the male in the paired house after growing with the unfamiliar female did not imply any change in the hormone level. They showed the same hormone level as it was before. This indicates that the induced social condition has caused a change in the hormonal level.

The guinea pigs have a different hormone system to establish less aggressive behavior when it lives in a colony. However, when they are transferred to pair housing, their system of hormones changes, and it results in more aggressive behavior. This is mainly to secure females from unfamiliar males. In this way, the animals are able to adapt their behavior to the new situation that favors evolutionary adjustment.
