  • Collaboration patterns in theoretical Population Genetics
    Scientometrics, 1998
    Co-Authors: Hildrun Kretschmer, B. M. Gupta
    Abstract:

    The paper points out that the characteristic properties of general social networks are reflected in co-authorship patterns of theoretical Population Genetics as studied from 1900 to 1980. The results are consistent with the analyses of bibliographies where the co-authorship networks in invisible colleges probably have shown the same behavioural patterns as the non-scientific Populations. The patterns of behaviour are portrayed in two-dimensional as well as three-dimensional representations of co-authorship data in theoretical Population Genetics.

  • Population Genetics of Host-Associated Microbiomes
    Current Molecular Biology Reports, 2019
    Co-Authors: Louis-marie Bobay, Kasie Raymann
    Abstract:

    Purpose of Review Host-associated microbiomes can play key roles in the health of animals and plants, but fundamental aspects of the dynamics and evolution of microbial communities are not fully understood. Recent Findings Several recent studies have sequenced and analyzed the entire diversity of microbial species and strains in different host-associated microbiomes. These studies analyze the Population Genetics of host-associated microbes, yet many questions remain unanswered. Summary In this review, we describe the key insights that have been gained by recent microbiome Population Genetics studies and how they have contributed to our understanding of the fundamental mechanisms that alter the Population dynamics of entire microbial communities. We further discuss the technical limitations of current approaches and how new methods and model systems would allow for better genetic characterization of host-associated microbiome Populations.

  • The limits of theoretical Population Genetics.
    Genetics, 2005
    Co-Authors: John Wakeley
    Abstract:

    THE purpose here is to discuss the limits of theoretical Population Genetics. This 100-year-old field now sits close to the heart of modern biology. Theoretical Population Genetics is the framework for studies of human history (Reich et al. 2002) and the foundation for association studies, which aim to map the genes that cause human disease (Jorde 1995). Arguably of more importance, theoretical Population Genetics underlies our knowledge of within-species variation across the globe and for all kinds of life. In light of its many incarnations and befitting its ties to evolutionary biology, the limits of theoretical Population Genetics are recognized to be changing over time, with a number of new paths to follow. Stepping into this future, it will be important to develop new approximations that reflect new data and not to let well-accepted models diminish the possibilities.

  • Microsatellite Data Analysis for Population Genetics
    Methods in molecular biology (Clifton N.J.), 2013
    Co-Authors: Kyung Seok Kim, Thomas W. Sappington
    Abstract:

    Theories and analytical tools of Population Genetics have been widely applied for addressing various questions in the fields of ecological Genetics, conservation biology, and any context where the role of dispersal or gene flow is important. Underlying much of Population Genetics is the analysis of variation at selectively neutral marker loci, and microsatellites continue to be a popular choice of marker. In recent decades, software programs to estimate Population Genetics parameters have been developed at an increasing pace as computational science and theoretical knowledge advance. Numerous Population Genetics software programs are presently available to analyze microsatellite genotype data, but only a handful are commonly employed for calculating parameters such as genetic variation, genetic structure, patterns of spatial and temporal gene flow, Population demography, individual Population assignment, and genetic relationships within and between Populations. In this chapter, we introduce statistical analyses and relevant Population genetic software programs that are commonly employed in the field of Population Genetics and molecular ecology.

  • Population Genetics strategies to characterize long-distance dispersal of insects
    Journal of Asia-Pacific Entomology, 2013
    Co-Authors: Kyung Seok Kim, Thomas W. Sappington
    Abstract:

    Abstract Population Genetics strategies offer an alternative and powerful approach for obtaining information about long-distance movement, and have been widely used for examining patterns and magnitude of insect dispersal over geographic and temporal scales. Such strategies are based on the principle that genetic divergence between local Populations reflects the interplay between genetic drift and gene flow, and thus can function as an indicator of dispersal capacity. Relatively new approaches for inferring Population history are widely applicable for documenting introduction routes of invasive or quarantine species. These approaches are based on genetic variability calculated from changes in gene frequency of subPopulations, measured using molecular genetic markers. Inferences from Population Genetics can supplement and corroborate conventional observational approaches for characterizing insect dispersal and have provided important clues to many questions raised in the field of behavior and ecology of insects. Here, we summarize our work on the boll weevil as a case study to illustrate the kinds of information on dispersal capacity and dispersal patterns that can be obtained from Population Genetics techniques that would be difficult or impossible to acquire in other ways. Then we provide examples of how the molecular markers and Population Genetics tools have been applied to answer immediate questions of relevance to eradication program managers. Though the latter are idiosyncratic to this particular pest, they demonstrate the kinds and range of problems that can be addressed in other systems through application of Population Genetics strategies.

  • Molecular Population Genetics.
    Genetics, 2017
    Co-Authors: Sònia Casillas, Antonio Barbadilla
    Abstract:

    Molecular Population Genetics aims to explain genetic variation and molecular evolution from Population Genetics principles. The field was born 50 years ago with the first measures of genetic variation in allozyme loci, continued with the nucleotide sequencing era, and is currently in the era of Population genomics. During this period, molecular Population Genetics has been revolutionized by progress in data acquisition and theoretical developments. The conceptual elegance of the neutral theory of molecular evolution or the footprint carved by natural selection on the patterns of genetic variation are two examples of the vast number of inspiring findings of Population Genetics research. Since the inception of the field, Drosophila has been the prominent model species: molecular variation in Populations was first described in Drosophila and most of the Population Genetics hypotheses were tested in Drosophila species. In this review, we describe the main concepts, methods, and landmarks of molecular Population Genetics, using the Drosophila model as a reference. We describe the different genetic data sets made available by advances in molecular technologies, and the theoretical developments fostered by these data. Finally, we review the results and new insights provided by the Population genomics approach, and conclude by enumerating challenges and new lines of inquiry posed by increasingly large Population scale sequence data.
