New publication - "Contact Calls Facilitate Group Contraction in Free-ranging Goats (Capra aegagrus hircus)"

The SwarmLab is happy to announce the publication of: O’Bryan, L., Abaid, N., Nakayama, S., Dey, T., King, A., Cowlishaw, G., et al. (2019). Contact Calls Facilitate Group Contraction in Free-ranging Goats (Capra aegagrus hircus). Frontiers in Ecology and Evolution 7, 73. doi:10.3389/fevo.2019.00073 Abstract: Many social animal species produce vocalizations believed to facilitate group contraction when one or more group members have become distant. However, the mechanisms underlying this function remain unclear for many species. We examined this question with data on a semi-free ranging group of 16 adult domesticated goats (Capra aegagrus hircus) inhabiting Tsaobis Nature... Read more.

New publication - "Temporal and spatial pattern of trail clearing in the Australian meat ant, Iridomyrmex purpureus"

The SwarmLab is happy to announce the publication of: Middleton, E. J. T., Garnier, S., Latty, T., and Reid, C. R. (2019). Temporal and spatial pattern of trail clearing in the Australian meat ant, Iridomyrmex purpureus. Anim. Behav. 150, 97–111. doi:10.1016/j.anbehav.2019.02.006 Abstract: Many ant species use trails to connect important resources. In addition, some ants actively clear obstacles from their trails. Although trail clearing is thought to be beneficial in decreasing travel time, the physical process of clearing requires an investment of time and energy. Given that trail clearing is a decentralized process, how do colonies decide... Read more.

Decision-making without a brain - Our new paper in Interface

How do organisms without brains make decisions? Most of life is brainless and the vast majority of organisms on Earth lack neurons altogether. Plants, fungi and bacteria must all cope with the same problem as humans – to make the best choices in a complex and ever-changing world or risk dying – without the help of a simple nervous system in many cases. Our lab in collaboration with Richard Mann (University of Leeds), James Marshall (University of Sheffield) and Tanya Latty (University of Sydney) recently studied this problem in the unicellular slime mold, Read more.

videoplayR v0.3 is out!

The people who know me a bit are very much aware of the fact that I am an avid R user AND proselyte. I perform all my data processing and visualization in R; I write reports and presentations in R; I even write R packages just for the pleasure of doing it (for instance, I created the editR package essentially to see how easy it would be to build a complete web-application with R. Hint: it’s not as hard as I thought it would be). While R is serving me very well, it always had one big... Read more.
