20.500.12556/DiRROS-19725 Dispersal similarly shapes both population genetics and community patterns in the marine realm Dispersal plays a key role to connect populations and, if limited, is one of the main processes to maintain and generate regional biodiversity. According to neutral theories of molecular evolution and biodiversity, dispersal limitation of propagules and population stochasticity are integral to shaping both genetic and community structure. We conducted a parallel analysis of biological connectivity at genetic and community levels in marine groups with different dispersal traits. We compiled large data sets of population genetic structure (98 benthic macroinvertebrate and 35 planktonic species) and biogeographic data (2193 benthic macroinvertebrate and 734 planktonic species). We estimated dispersal distances from population genetic data (i.e., FST vs. geographic distance) and from %-diversity at the community level. Dispersal distances ranked the biological groups in the same order at both genetic and community levels, as predicted by organism dispersal ability and seascape connectivity: macrozoobenthic species without dispersing larvae, followed by macrozoobenthic species with dispersing larvae and plankton (phyto- and zooplankton). This ranking order is associated with constraints to the movement of macrozoobenthos within the seabed compared with the pelagic habitat. We showed that dispersal limitation similarly determines the connectivity degree of communities and populations, supporting the predictions of neutral theories in marine biodiversity patterns. sea phytoplankton dispersal distribution ocean sampling Atlantic Ocean Gulf of Trieste morje plankton raziskovanje morja fitoplankton disperzija biološka oceanografija true false true Angleški jezik Slovenski jezik Neznano 2024-07-24 03:47:47 2024-07-25 17:42:34 2024-07-26 04:28:24 0000-00-00 00:00:00 2016 0 0 Nasl. z nasl. zaslona; Opis vira z dne 29. 6. 2016; str. 1-12 28730 Vol. 6 2016 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2016-06-27 574.1 2045-2322 10.1038/srep28730 3927375 http://dx.doi.org/10.1038/srep28730 1 0e28c59c-494e-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=27243 RAZ_Chust_Guillem_2016.pdf RAZ_Chust_Guillem_2016.pdf 1 3A5B6CACD641EE590B25CE25F69FA1C5 c6c9f56a6a875ad9534a312b65f1e47da95005c94e8961c698ff4189569c3e26 65d0461d-4a8c-11ef-b487-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=27545 Nacionalni inštitut za biologijo 0 0 0
