Stand development stages and recruitment patterns influence fine-scale spatial genetic structure in two Patagonian Nothofagus species

Abstract: Key message Nothofagus alpina (Poepp. et Endl.) Oerst. and Nothofagus obliqua (Mirb.) Oerst forests have strong fine-scale spatial genetic structures. The intensity of genetic structure patterns differed according to species, stand development stages, life stages, and spatial arrangement of regeneration groups. This data becomes useful for forest management as it provides an understanding of how populations evolve as well as of the consequences of disturbances and enables the establishment of s… Show more

“…This means that mortality during this period is independent of planting density. However, over forty years, the gradual closure of crowns and root systems as trees increase in size is leading to the emergence and gradual increase of competition for limited resources [69][70][71][72], primarily sunlight and water. The nonlinear increase in size with age causes the observed negative exponent in the dynamics of stand density.…”

“…It typically depends on various biotic and abiotic factors such as pollination, dispersal, seed predation and germination success (Connell, 1971;Janzen, 1970;Wright, 2002). Moreover, regeneration success of lightdemanding species also depends on natural and anthropogenic disturbances (Morin-Rivat et al, 2017;Sola et al, 2022;Tappeiner et al, 1997). By disrupting ecosystem structure and changing resource availability, and especially access to light, disturbances create the conditions for a new succession of species (Yamamoto, 2000).…”

“…Regeneration success of light-demanding species also depends on intrinsic factors such as the mating system and the extent of seed and pollen dispersal (Hardy et al, 2019), processes affecting in turn the demographic, spatial and genetic structures of tree populations (Luambua et al, 2021;Sola et al, 2022). Most tropical tree species are allogamous but self-compatible and occur at low population density (Duminil et al, 2016a;Duminil et al, 2016b;Hardy et al, 2019).…”
