The social interaction between college residents is not just human, new research on vampire bats has revealed.

The Vampire bat groups that were forced to stay together for only one week continued their romantic relationship for two months after they were released to a large community.

The study provides anecdotal information about wildlife that is based on the effects of accurate measurements of social manipulation rather than just observation.

“The process of how to make a living is a mystery that many people want, but the definition of how it works is different,” said Gerald Carter. senior author of the study and assistant professor of evolution, ecology and organismal biology at The Ohio State University.

“We’re trying to build vampire garbage as a system where we can really test these explanations… Of time. It’s never been done before.”

The study was led by Imran Razik with assistance from Bridget Brown, Ohio State graduate student in evolution, ecology and organismal biology. Carter and Razik worked with the Smithsonian Tropical Research Institute in Panama, where the study took place.

The research is published in a journal Palapala Biology.

The team captured seven adult female vampire bats from each of the three remote locations to assemble a colony of 21 bats for training.

For the first six weeks, the vampire bats only mingled with fellow locals and visitors from other areas. Then, during storage, the researchers divided the bats into seven small groups. For each group, they chose one bat from each of the three sites and asked them to stay together as three for seven days.

The bats that lived together were seen as experimental companions whose ornamentation was compared to two other types – two other types – the navigators were not required to be nearby, and the Native bats caught from the same house.

After the treatment period, all the bats remained for nine weeks.

In the three study sessions, Razik observed and observed 5 -second or more magnetic field interactions captured by three infrared cameras operating for six hours each day.

“From a long time ago, they could start training relationships, and then we worked on a level of motivation to see if we could increase the amount of training in pairs. training after maintenance, ”Razik said.

The results showed that, due to the overall change in the amount of social training, social training was significantly higher in the test partners than in the control and pairs.

“It’s a great example,” Carter said. “One thing you have to think about, after these bats were in their‘ school restroom ’, they stayed together for a while after that but it went away quickly – but we didn’t see that. … They were better than the power bats until the end of the experiment, nine weeks later. “

Razik found that many of the new test partners did the same training for the first six weeks, but the team focused on their evaluation of the effect of the training that was isolated on creating relationships. always connected.

“During the training, each bat had two friends with whom they could interact, and during the training they had about 20 other friends with whom they could interact. “Even if some of them know they’ve been caught on the same site,” he said. “So the desire was seen and it became clear in nine weeks that there was a significant impact – and the impact was clear in all the ways we analyzed the data.”

This single study does not resolve the question of how social security in the wild, which is considered important for animal health, well -being, survival and reproductive health. . The scholarly debate continues over the importance of the underlying causes: Are the animals attracted to others in similar ways, or in opposition? Is it enough to live close enough to be friends, or are bonds established by offering help?

“What this experiment tells us is that there’s a fundamental relationship between being placed in the same atmosphere and actually having a desire for each other later on,” Carter said. “That’s why the college restroom is a great example: You’re connected to someone and so you keep looking for that person afterwards. It’s not clear how much this does to animals. Other. ”
