With or without you: Gut microbiota does not predict aggregation behaviour in females of the European earwig
<p>Recent studies suggest that the gut microbiota could be one of the main driving forces behind the evolution of group living. However, these studies are mainly based on our knowledge of species in which non-social individuals are rare and abnormal, calling into question the adaptive value of the reported association between group-living and gut microbiota. In this study, we addressed this issue by testing this association in females of the European earwig, an insect showing frequent, naturaland wide inter-individual variation in the expression of group living. We video-tracked 320 field-sampled females to quantify their natural variation in aggregation and then tested whether the most and least gregarious females had different gut microbiota. We also compared the general activity, boldness, body size and body condition of these females and examined the association between each of these traits and the gut microbiota. Contrary to our predictions, we found no difference in gut microbiota between the most and least gregarious females, as well as no difference between these females in terms of general activity, boldness, body size and condition. We did show that the gut microbiota of females was overall linked to their body condition, even though it was also unrelated to the other measurements. Overall, these results demonstrate that a host's gut microbiota is not necessarily a major driver of aggregation behaviour in species with inter-individual variation in group living and call for future studies to investigate the determinants and role of gut microbiota in earwigs.</p>

Data from: Viral infection causes sex-specific changes in fruit fly social aggregation behaviour
Host behavioural changes following infection are common and could be important determinants of host behavioural competence to transmit pathogens. Identifying potential sources of variation in sickness behaviours is therefore central to our understanding of disease transmission. Here, we test how group social aggregation and individual locomotor activity vary between different genotypes of male and female fruit flies (Drosophila melanogaster) following septic infection with Drosophila C Virus. We find genetic-based variation in both locomotor activity and social aggregation but we did not detect an effect of DCV infection on fly activity or sleep patterns within the initial days following infection. However, DCV infection caused sex-specific effects on social aggregation, as male flies in most genetic backgrounds increased the distance to their nearest neighbour when infected. We discuss possible causes for these differences in the context of individual variation in immunity and their potential consequences for disease transmission.
Aggregated dataset on preferences about top persuasive strategies and principles to influence pro-environmental behaviour change
<p>This dataset is an aggregation of two datasets, in total, it has 743 entries.</p> <p>For a full immersion on the data collected in both surveys. The Greensoul dataset is made up of a pre-pilot dataset with 303 responses and a post-pilot with 65 responses.</p> <ul> <li> <p>https://zenodo.org/records/2610102</p> </li> <li> <p><a href="../records/3565757">https://zenodo.org/records/3565757</a></p> </li> </ul> <p><strong></strong>The second one through the Prolific platform (https://www.prolific.co/) with 375 new responses from the same four countries (Spain, Austria, UK and Greece). Furthermore, we used a similar screening methodology employed in the first survey during the GreenSoul project.</p>
Data for: Aggregation in an heterospecific population of blowfly larvae: social behaviour is impacted by species-specific thermal requirements and settlement order
<p><span>Larvae of several blow fly species grow on carcasses and actively aggregate together. They face harsh developmental conditions resulting in a strong pressure to reduce development time: this is achieved either through thermoregulation or aggregation. We investigate how these two developmental strategies are modulated within heterospecific groups. In the first experiment, larvae of two species with different thermal requirements were deposited simultaneously on a thermal gradient. This resulted in the formation of two monospecific groups, each located at the species-specific thermal preferendum. However, when <em>Calliphora</em> <em>vomitoria</em> (Linnaeus) larvae were placed first, the later coming <em>Lucilia</em> <em>sericata</em> (Meigen) larvae attracted the whole group to its own thermal preferendum. In the reverse experiment, a half of the replicates resulted in single dense heterospecific groups observed at temperatures ranging from <em>C. vicina</em> to <em>L. sericata</em> preferendum. The other half of the replicates resulted in loose groups spread out on the thermal gradient. These results highlight the emergence of collective decisions ranging from thermal optimization to heterospecific aggregation at suboptimal temperatures. They demonstrate that species settlement order strongly affects self-organization processes and mixed-species group formation. We conclude that thermal optimization and heterospecific niche construction are two developmental strategies of carrion fly larvae.</span></p>
