10 Great (And Not-So Great) Social Distancers of the Animal Kingdom

In the time of a global crisis like the one we’re in now, it’s more important than ever that we pay attention to what scientists are saying.

However, my colleagues and I are ecologists, and as such don’t really have as much practical advice for you as epidemiologists and sociologists do right now. All we can really say is stay at home, and practice physical distancing (NOT social distancing, we need each other more than ever right now).

However not all species have the comfort of being social without being close to each other. So in the name of providing some entertainment in difficult times, I gathered a bunch of colleagues together to figure out how some of their study organisms would cope if the need to socially distance was imposed on them.

The Crux

Climate change is something that we hear about on a daily basis. The dire warnings tend to concern sea levels rising and temperatures varying so much that we have more intense and deadly storms than before, but these are all direct effects of the climate. Another thing that climate change can do is have indirect effects on organisms.

Organisms with complex life cycles spend the juvenile part of their lives in one environment before moving on to the adult stage in another environment. The researchers in this study wanted to know how simulated climate change during the juvenile stage of the organisms lifetime could affect the adult stage.
