Data for: Co-evolution of dormancy and dispersal in spatially autocorrelated landscapes

The evolution of dispersal can be driven by spatial processes, such as landscape structure, and temporal processes, such as disturbance. Dormancy, or dispersal in time, is generally thought to evolve in response to temporal processes. In spite of broad empirical and theoretical evidence of trade-offs between dispersal and dormancy, we lack evidence that spatial structure can drive the evolution of dormancy. Here, we develop a simulation-based model of the joint evolution of dispersal and dormancy in spatially heterogeneous landscapes. We show that dormancy and dispersal are each favored under different landscape conditions, but not simultaneously under any of the conditions we tested. We further show that, when dispersal distances are short, dormancy can evolve directly in response to landscape structure. In this case, selection is primarily driven by benefits associated with avoiding kin competition. Our results are similar in both highly simplified and realistically complex landscapes.

Supplementary data to accompany Gernon, T.M., Hincks, T.K., Brune, S., Braun, J., Jones, S.M., Keir, D., Cunningham, A., & Glerum, A., Co-evolution of craton margins and interiors during continental breakup. Nature (Accepted in Principle at time of writing, 3 June 2024). Constraining thermochron uncertainty We utilise published thermochron model data for 46 sites across southern Africa from Brown et al. (2002); Green et al. (2017); Kounov et al. (2013) and (2009); Stanley et al. (2020), (2015) and (2013); Tinker et al. (2008), and Wildman et al. (2017), (2016) and (2015).  The above studies present model uncertainty in slightly different ways. However, we have attempted to provide equivalent estimates of uncertainty across the board in our analysis.  Stanley and Flowers (2020) provide individual simulation runs for 15 sites, and we use these directly to estimate maximum temperature drop and associated timing for each simulation. For the 12 sites provided by Wildman et al. (2017, 2016, 2015), we use the best fit and 95 percentile envelope, and assume the 'good fit' envelopes of Kounov et al. (2009) to be broadly equivalent. For 15 sites (see MinMax.csv) we utilise the best fit curve together with an estimate of the minimum and maximum plausible timing of the point of maximum temperature drop. Green et al. (2017) provides only a best fit curve, and in the absence of further data we cannot provide an uncertainty estimate here.  Files provided SourceData.csv Summary of each site, associated data source(s), coordinates and model uncertainty. Please see references listed within for complete thermochron model descriptions and original data. MinMax.csv Name/Location and references for thermochron source data for 15 sites with best fit curves, and estimates of the min/max time of maximum temperature drop. Tmin and Tmax (degrees C) are the minimum and maximum modelled temperatures for each location. t1_Ma and t2_Ma are the minimum and maximum times (Ma) where the model simulations (best, good or acceptable fit) reach the midpoint temperature Tmid= (Tmax -Tmin)/2 The most likely timing is taken from the best fit curve.  Files in Thermochron_bestfit Best fit thermochron curves (Age in Ma, and Temp in degrees C) for 31 sites digitized from the original publications. Names correspond to File Names in SourceData.csv, which also provides references. Files in Thermochron_Envelopes Lower and Upper 95 percentile thermochron envelopes (denoted *_L95.csv or *_U95.csv) for 12 sites, digitized from Wildman et al. (2017, 2016, 2015). Lower and Upper good fit thermochron envelopes (denoted *_L.csv or *_U.csv) for three sites, digitized from Kounov et al. (2009) Age in Ma, and Temp in degrees C.   Files in Stanley2020_model_runs Individual model output directly from Stanley and Flowers 2020 for 15 sites (no modification of original published data).

Paradoxes in the co-evolution of contagions and institutions

Epidemic models study the spread of undesired agents through populations, be it infectious diseases through a country, misinformation in social media, or pests infesting a region. In combating these epidemics, we rely neither on global top-down interventions, nor solely on individual adaptations. Instead, interventions commonly come from local institutions such as public health departments, moderation teams on social media platforms, or other forms of group governance. Classic models, which are often individual or agent-based, are ill-suited to capture local adaptations. We leverage developments of institutional dynamics based on cultural group selection to study how groups attempt local control of an epidemic by taking inspiration from the successes and failures of other groups. Incorporating institutional changes into epidemic dynamics reveals paradoxes: a higher transmission rate can result in smaller outbreaks as does decreasing the speed of institutional adaptation. When groups perceive a contagion as more worrisome, they can invest in improved policies and, if they maintain these policies long enough to have impact, lead to a reduction in endemicity. By looking at the interplay between the speed of institutions and the transmission rate of the contagions, we find rich co-evolutionary dynamics that reflect the complexity of known biological and social contagions.
