Data from: Tracking individuals shows spatial fidelity is a key regulator of ant social organization

Danielle P. Mersch, Alessandro Crespi & Laurent Keller
Ants live in organized societies with a marked division of labor among workers, but little is known about how this is generated. We use a tracking system to continuously monitor individually-tagged workers in six colonies of the ant Camponotus fellah over 41 days. Network analyses of over 9 million interactions revealed three distinct groups that differ in behavioral repertoires. Each group represents a functional behavioral unit with workers moving from one group to the next...

Data from: Shifting fitness landscapes in response to altered environments

Ryan T. Hietpas, Claudia Bank, Jeffrey D. Jensen & Daniel N. A. Bolon
The role of adaptation in molecular evolution has been contentious for decades. Here, we shed light on the adaptive potential in Saccharomyces cerevisiae by presenting systematic fitness measurements for all possible point mutations in a region of Hsp90 under four environmental conditions. Under elevated salinity, we observe numerous beneficial mutations with growth advantages up to 7% relative to the wild type. All of these beneficial mutations were observed to be associated with high costs of...
