Social environment drives sex and age-specific variation in Drosophila melanogaster microbiome composition and predicted function [article]

Thomas Leech, Laurin McDowall, Kevin P Hopkins, Steven M Sait, Xavier A Harrison, Amanda Bretman
2020 bioRxiv   pre-print
We used social contexts that particularly alter the development and lifespan of males, predicting that any intrinsic social effects on the microbiome would therefore be sex-specific.  ...  Social environments influence multiple traits of individuals including immunity, stress and ageing, often in sex-specific ways.  ...  Since post-infection lifespan data was 378 limited to one week, a chi squared test was used to determine if the number of flies that died 379 differed by sex and social environment.  ...

Exploratory behavior is linked to stress physiology and social network centrality in free-living house finches ( Haemorhous mexicanus )

Moore, and Dana M. Hawley. "Exploratory behavior is linked to stress physiology and social network centrality in free-living house finches (Haemorhous mexicanus)."  ...  Overall, our results indicate that individual differences in exploratory behavior are linked to variation in both stress physiology and social network traits in free-living house finches.  ...  However, our data did not show a significant link between exploratory behaviors in a novel environment and the number of feeders used in the wild.  ...

2016 Animal Behaviour  
In general, position in the social network and, in particular, space sharing appears to be more important than the immunosuppressive effects of physiological stress or host traits in determining risk of  ...  Infectious disease transmission is a cost of sociality in humans and other animals. Nevertheless, the mechanisms linking social behaviour to infection risk are poorly known.  ...  Acknowledgments We thank Festus Onajde, Rosemary Gbegbaje and CERCOPAN staff for their assistance with data collection and support in the field, and Mason Saari, Kelsey Brown, Nicholas Segel and Julia  ...

Insights from evolutionarily relevant models for human ageing

Melissa Emery Thompson, Alexandra G Rosati, Noah Snyder-Mackler
2020 Philosophical Transactions of the Royal Society of London. Biological Sciences  
This work comprises data and theory on non-human primates, as well as under-represented data on humans living in small-scale societies, which help elucidate how environment shapes senescence.  ...  Component papers address (i) the critical processes that comprise senescence in long-lived primates; (ii) the social, ecological or individual characteristics that predict variation in the pace of ageing  ...  Sex differences in reproductive effort are predicted to yield differences in health and longevity.  ...

The transcriptomic signature of low aggression in honey bees resembles a response to infection

Clare C. Rittschof, Benjamin E. R. Rubin, Joseph H. Palmer
2019 BMC Genomics  
Many organisms display a generalized suite of behaviors that indicate infection or predict infection susceptibility.  ...  In the fat body, and to some degree the midgut, our data specifically support the hypothesis that low aggression resembles a diseased or parasitized state.  ...  Acknowledgements We thank James Harrison for help with gene descriptions, and Adam Baker for developing the honey bee schematic in Fig. 1 .  ...

Social environmental effects on gene regulation

Jenny Tung, Yoav Gilad
2013 Cellular and Molecular Life Sciences (CMLS)  
Social environmental conditions, particularly the experience of social adversity, have long been connected with health and mortality in humans and other social mammals.  ...  Gene expression responses to the social environment are, in turn, mediated by a set of underlying regulatory mechanisms, of which epigenetic marks are the best studied to date.  ...  Open Access This article is distributed under the terms of the Creative Commons Attribution License which permits any use, distribution, and reproduction in any medium, provided the original author(s)  ...
