Social interactions in two species of social amoebae Dictyostelium discoideum and Dicyosteliuum purpureum
The core of sociality and one of the key forces behind the transition to multicellularity is cooperation. The study of social behavior in microorganisms has gained considerable attention in the last decade as researchers ...
Cooperation, conflict, and experimental evolution in social amoebae
Cooperation and cheater control have helped shape life as we know it, but there is still much to learn. A eukaryote microbial model organism, like Dictyostelium discoideum , is an excellent system for advancing our ...
Anoplolepis gracilipes invasion of the Samoan Archipelago: Can mutualisms with native species amplify ecological consequences?
Integrating mutualism into the study of ecological communities is likely to be critical to understanding community dynamics and to predict the consequences of anthropogenic changes to ecosystems. Invasive species are among ...
Evolutionary costs and benefits of a newly discovered symbiosis between the social amoeba Dictyostelium and bacteria
Recent work has shown that microorganisms are surprisingly like animals in having sophisticated behaviours such as cooperation, communication, and recognition, as well as many kinds of symbioses. Here we show first that ...
Evolutionary Genetics of Dictyostelids: Cryptic Species, Sociality and Sex
Dictyostelium discoideum serves as an ideal system to study social evolution because of the social stage of its lifecycle, where individuals aggregate to build a multicellular structure. However, much of its basic biology ...
