WebThe rate of these surfing events is shown to sensitively depend on the strength of genetic drift, which varies among strains and environmental conditions. More generally, allele surfing promotes the rate of adaptation per biomass produced, which could help developing biofilms and other resource-limited populations to cope with environmental ... WebIn the case of humans, the genetic diversity decreases essentially linearly with increasing geographic distance from Africa [2, 3], which is indicative of the human mi-gration out of …

WebDec 1, 2016 · Genetic surfing does not modify the total number of derived alleles in a population or in an individual genome, but it leads to a loss of heterozygosity along the expansion axis, implying that derived alleles are more often in homozygous state. … Genetic surfing results from the stochastic evolution of allele frequencies on … The present study aims at characterizing the stochastic process of gene surfing … Introduction. Current evidence, from studies of experimental evolution and patterns … A stepping-stone model combined with coalescence theory is used to predict … Gene surfing: When a population expands its density at the wave front is usually … The molecular revolution has facilitated detailed spatial genetic analyses of … Here we add further compelling evidence supporting the RAO model by showing … Several patterns emerge from a comparison of the per-individual total lengths of ROH … The standard approaches to detecting selection in population genetic data … Finally, we used different models to infer population parameters from the data. … WebWe found that both habitat dynamics and dispersal capacity, as well as their interaction, were the drivers of emergent pattern of genetic diversity and allele surfing. Specifically, … google earth engine reduce region

WebThe SURF1 gene provides instructions for making a protein that is important in oxidative phosphorylation, the process by which the energy from food is converted into a form cells … WebApr 7, 2024 · In the context of range expansions, the concepts of gene surfing, sectors, and embolisms have been invoked to explain patterns of genetic variation in a wide range of plant (53–55), animal (56, 57), and microbial populations. Our work shows that these heuristics are incomplete when long-range dispersal is present: Sectors give way to blobs ... WebAug 24, 2024 · Long-standing adaptation to the harsh desert environment may confine the genetic diversity of A. mongolicus, despite its distribution over a wide range of longitude, latitude, and altitude. Since range edges defined by climate niches may have different genetic responses to environmental extremes, we compared genome-wide … google earth engine registration
