Code and supplementary information for the speed of neutral evolution on graphs
<p>The speed of evolution on structured populations is crucial for biological and social systems. The likelihood of invasion is key for evolutionary stability, but it makes little sense if it takes long. It is far from known what population structure slows down evolution. We investigate the absorption time of a single neutral mutant for all the 112 non-isomorphic undirected graphs of size 6. We find that about three-quarters of the graphs have an absorption time close to that of the complete graph, less than one-third are accelerators, and more than two-thirds are decelerators. Surprisingly, determining whether a graph has a long absorption time is too complicated to be captured by the joint degree distribution. Via the largest sojourn time, we find that echo-chamber-like graphs, which consist of two homogeneous graphs connected by few sparse links, are likely to slow down absorption. These results are robust for large graphs, mutation patterns as well as evolutionary processes. This work serves as a benchmark for timing evolution with complex interactions and fosters the understanding of polarization in opinion formation.</p>

Using niche centrality within the scope of the nearly neutral theory of evolution to predict genetic diversity in a tropical conifer species-pair
<p><b>Aim:</b> Estimating genetic diversity is key for understanging biogeographic and evolutionary processes. However, gathering genetic information is not feasible for all taxa or populations, particularly in the tropical regions. Identifying proxies for inferring such values has thus become essential. Here, we built on the niche centrality hypothesis (NCH; or central-abundance hypothesis) and the nearly neutral theory of evolution (NNT) to identify some of such proxies using a montane tropical conifer species-pair as model. The NCH predicts more genetic diversity under optimal ecological conditions, which should also allow for more efficient purifying selection, according to the NNT.</p> <p><b>Location:</b> The Transmexican Volcanic Belt, central Mexico.</p> <p><b>Taxa:</b> A fir species-pair endemic to central Mexico,<b> </b><i>Abies flinckii </i>and<i> A. religiosa.</i></p> <p><b>Methods:</b> We estimated patterns of genetic diversity from nuclear SSRs (<i>A</i>, <i>H</i><sub>E</sub>), and gene-coding sequences (<i>π</i><sub>S</sub>, <i>π</i><sub>N</sub>), together with the efficacy of purifying selection, measured as <i>π</i><sub>N</sub>/<i>π</i><sub>S</sub>. After testing for niche overlap, we used several geographic and ecological proxies (i.e. longitude, latitude, elevation, estimated area, and distance to the niche centroid in the present and in the LGM) to predict genetic diversity and <i>π</i><sub>N</sub>/<i>π</i><sub>S</sub> using general linear models.</p> <p><b>Results:</b> Populations at the west of the Trans Mexican Volcanic Belt (TVB) had lower genetic diversity than populations in the east of this mountain chain. Both species had significant niche overlap. The principal predictors for neutral genetic diversity (<i>H</i><sub>E</sub>, <i>A</i> and <i>π</i><sub>S</sub>) were longitude and latitude, followed by the current distance to the niche centroid; the efficiency of purifying selection was mostly accounted for by the current distance to the niche centroid (which was also correlated to elevation). No correlation was observed between genetic diversity or <i>π</i><sub>N</sub>/<i>π</i><sub>S</sub> and current population area.</p> <p><b>Main conclusions:</b> Historical and ecological factors have to be taken into account for explaining the amounts of genetic diversity in mountain tropical species. Following the NTT, populations closer to the niche centroid are more efficient at eliminating slightly deleterious mutations than marginal stands, independently of their size or geographical location (longitude). Expanding the central-abundance theory within the scope of the NTT might help reconciling conflicting views concerning the extent of its empirical support.</p>

Data from: Neutral genetic processes influence MHC evolution in threatened gopher tortoises (Gopherus polyphemus)
Levels of adaptive genetic variation influence how species deal with environmental and ecological change, but these levels are frequently inferred using neutral genetic markers. Major histocompatibility complex (MHC) genes play a key role in the adaptive branch of the immune system and have been used extensively to estimate levels of adaptive genetic variation. Parts of the peptide binding region, sites where MHC molecules directly interact with pathogen and self-proteins, were sequenced from a MHC class I (95/441 tortoises) and class II (245/441 tortoises) gene in threatened and non-threatened populations of gopher tortoises (Gopherus polyphemus), and adaptive genetic variation at MHC genes was compared to neutral genetic variation derived from 10 microsatellite loci (441 tortoises). Genetic diversity at the MHC class II locus and microsatellites was greater in populations in the non-threatened portion of the gopher tortoise's range (MHC class II difference in mean A = 8.11, AR = 0.79, HO = 0.51, and HE = 0.16; microsatellite difference in mean A = 1.05 and AR = 0.47). Only MHC class II sequences showed evidence of positive selection (dN/dS > 1, Z = 1.81, P = 0.04). Historical gene flow as estimated with Migrate-N was greater than recent migration estimated with BayesAss, suggesting that populations were better connected in the past when habitat was less fragmented. MHC genetic differentiation was correlated with microsatellite differentiation (Mantel r = 0.431, P = 0.001) suggesting neutral genetic processes are influencing MHC evolution, and advantageous MHC alleles could be lost due to genetic drift.

Data from: Evolution of a dominant natural isolate of Escherichia coli in the human gut over the course of a year suggests a neutral evolution with reduced effective population size
In vitro and in vivo evolution experiments on Escherichia coli revealed several principles of bacterial adaptation. However, few data are available in the literature describing the behavior of E. coli in its natural environment. We attempted here to study the evolution in the human gut of a commensal dominant E. coli clone ED1a belonging to B2 phylogroup, through a longitudinal genomic study. We sequenced 24 isolates sampled at three different time points within a healthy individual over almost a year. We computed amutation rate of 6.90x10-7 per base per year of the chromosome for E. coli ED1a in healthy human gut. We observed a very limited genomic diversity, and could not detect any evidence of selection contrary to what is observed in experimental evolution over similar length of time. We therefore suggest that ED1a being well adapted to the healthy human gut evolves mostly neutrally with a low effective population size (Ne ≈ 500 – 1700).
