UCLA life scientists provide important new details on how climate change will affect interactions between species in research published online May 21 in the Journal of Animal Ecology. This knowledge, they say, is critical to making accurate predictions and informing policymakers of how species are likely to be impacted by rising temperatures.

“There is a growing recognition among biologists that climate change is affecting how species interact with one another, and that this is going to have very important consequences for the stability and functioning of ecosystems,” said the senior author of the research, Van Savage, an assistant professor of ecology and evolutionary biology and of biomathematics at UCLA. “However, there is still a very limited understanding of exactly what these changes will be. Our paper makes progress on this very important question.” (more…)

Social Networking: Gen Xers Connect Online as Often as They Socialize in Person

ANN ARBOR — Young adults in Generation X are as likely to connect with friends, family and co-workers online as they are in person, according to a University of Michigan study.

In a typical month, adults in their late 30s report that they engaged in about 75 face-to-face contacts or conversations, compared to about 74 electronic contracts through personal emails or social media. (more…)

Some Dating Websites Do Not Remove GPS Data From Photos, CU-Boulder Students Find

While the majority of dating websites do a good job of managing the privacy of their users, a class research project at the University of Colorado Boulder’s Leeds School of Business found that 21 of 90 dating websites the class examined did not properly remove location data from pictures uploaded by their users.

As a result of people taking more photographs with cameras and cell phones containing Global Positioning System chips, some dating website profile pictures contain GPS coordinates showing where a picture was taken, said Associate Professor Kai Larsen, who taught the class on Privacy in the Age of Facebook. When such information is not removed by the dating website, commonly available tools can be used to detect the location of a person’s residence or other locations frequented by the user. (more…)

‘Social Relationships in Animals Have a Genetic Basis’

The ability to tolerate aggression is partly genetic, UCLA life scientists report in the first study to demonstrate a genetic component to a social network trait in a non-human population.

“The ability to tolerate aggression is passed on across generations; there is genetic variation in the ability to tolerate aggression,” said the study co-author Daniel T. Blumstein, professor and chair of ecology and evolutionary biology at UCLA.

Blumstein, a leader in the field of applying social network statistics to animals, and his colleagues studied four groups of yellow-bellied marmots, which are related to squirrels, over six years in the Rocky Mountains of Colorado. Each group included 15 to 30 marmots. (more…)
