Very few extant Neotropical dispersers, like tapirs, can have larger seed loads per scat, allowing the dispersal of much larger individual seeds.
The window for dispersal was much shorter in the case of CP4/EPSPS, whose most likely source is NK603, released in the US in 2001.
There is no parameter space where paternal inheritance is favoured by selection (i.e., where Zm < 0), even when pollen dispersal is much lower than seed dispersal.
If mean seed dispersal is much larger than the size of environmental patches, there is no more advantage for the maternal strategy (Zm ~ 0).
Taylor and Buckling (2010) found that the benefit of dispersal was much higher in clonal (highly related, or kin based) bacterial populations, and these clonal populations were more likely to disperse under very high resource-dependent costs than mixed dispersal strategy populations.
That's because in the age of the great dispersal, it becomes much easier to search out and congregate with people who are basically like yourself.
In South Asia much dispersal of rice took place after Indo-Aryan and Dravidian speakers adopted rice from speakers of lost languages of northern India.
Still, it is not clear how much dispersal rates may accelerate under climate change, but it is very likely that the southern parts of the forest zone will be under very high risk, and the potential loss or decline of southern taiga forests will not be compensated for by increasing forest area beyond the current northern tree line.
However, the impact of climate on philopatry and dispersal has received much less attention [8], [9].
However, limited dispersal is probably much more important in microbes because due to the clonal reproduction mode it would tend to keep close relatives together.
