There are several different steps involved in the colonization process: the release of gametes by reproductive adults (fertilization may be internal or external); larval dispersal in the water column and delivery to suitable habitats; larval settlement and metamorphosis; and lastly, survival, growth and recruitment to the adult population.
We used lagrange[ 3] to obtain the likeliest dispersal scenarios at all internal nodes of the dated consensus tree (with outgroups removed) under the DEC model.
The transition rates and the reconstruction of the likeliest dispersal scenarios at all internal nodes under the DEC model were estimated using the C++ version of lagrange.
To trace the historical biogeography during the evolution of the Glyptosternoids, the ancestral distribution of the internal nodes were reconstructed with the Dispersal-Extinction-Cladogenesis (DEC) model [ 55] using the RASP program v. 3.02.
Ancestral areas at internal nodes within Pseuduvaria are determined using dispersal-vicariance analysis (DIVA) and weighted ancestral area analysis (WAAA).
Individual dispersal decisions may be affected by the internal state of the individual and the external information of its current environment.
Moreover, further advective processes often entail little internal mixing or create confined water bodies, thus constraining viral particle dispersal.
The DIVA and DEC methods allow the range of extant species and internal nodes (ancestral species) to encompass multiple discrete areas, and identify dispersal, vicariance or area extinction events.
To calculate the posterior probability of ancestral distribution at internal nodes, we used a Bayesian approach implemented in the updated version of Statistical Dispersal Vicariance Analysis (S-DIVA), RASP v.2.0b [ 67, 68], and our generic-level phylogeny.
See that as its central park, an internal equivalent of London's "green belt".The city councils concerned, happy to challenge the orthodoxy of dispersal, were swift to back this idea in 1998.
Accordingly, "context dependent dispersal" has disappeared from the current dispersal theory, whereas "phenotypic dependent dispersal" means now dispersal depending on the internal state of the individual, which is affected by many environmental factors like starvation, parasite load, density or sex-ratio.
