Analysis of spatial genetic structure in an expanding Pinus halepensis population reveals development of fine‐scale genetic clustering over time

Abstract: We analysed the change of spatial genetic structure (SGS) of reproductive individuals over time in an expanding Pinus halepensis population. To our knowledge, this is the first empirical study to analyse the temporal component of SGS by following the dynamics of successive cohorts of the same population over time, rather than analysing different age cohorts at a single time. SGS is influenced by various factors including restricted gene dispersal, microenvironmental selection, mating patterns and the spatial p… Show more

“…A limited seed and/or pollen dispersal, due to the heterogeneity of the habitat, may explain this observation (Escudero et al, 2003;Troupin et al, 2006;Van Rossum and Triest, 2007 laperrinei in Niger associated with limited seed dispersal and low density of maternal seed sources may also have created genetic structure within population (Dutech et al, 2002;Jones and Hubbell, 2006). In contrast, the absence of SGS within Algerian populations could be due to long persistence of subsp.…”

“…However, fine-scale genetic structure is not simply determined by the range of gene dispersal. Recent studies have pointed out the influence of other biotic or abiotic factors, such as the spatiotemporal pattern of seedling recruitment (Schnabel and Hamrick 1995;Parker et al 2001), the population disturbance history (Miyamoto et al 2003;Jacquemyn et al 2006;, habitat fragmentation (Ally and Ritland 2007;Yamagishi et al 2007), and microenvironmental selection (Troupin et al 2006). These instances indicate that a complex interaction of ecological factors likely occurs in shaping the population genetic structure in plant species.…”

“…Current statistical approaches to population genetic structure in a spatial context derive from the theoretical model of isolationby-distance (IBD) formulated by Sewall Wright (Wright 1943). The identification and quantification of SGS have long caught the attention of evolutionary biologists aware of its importance in the understanding of the evolutionary processes acting in plant populations (Epperson 1992;Troupin et al 2006;Pardini and Hamrick 2008;Hirao 2010;Amat et al 2013). Random genetic drift, natural selection, and restricted gene dispersal, acting in combination or solely, are the basic determinants of the intensity and dynamics of SGS (Wright 1943).…”
