In this respect the genus is more similar in ecological preference to Betulaceae than to Fagaceae and perhaps can be thought of as the Southern Hemisphere counterpart of the birches.
Because of the strongly supported phylogenetic relationship and apparent cohesiveness in terms of their perennation mode, geographic distribution, and ecological preference, Chung et al. ([2014]) expands the concept of Begonia sect.
This ecological preference of G. ruber and the incorporation of Ba into foraminifera shells makes Ba/Ca ratios in fossil G. ruber a proxy for the influence of river discharge on salinity (Weldeab et al. 2007; Schmidt and Lynch-Stieglitz 2011).
Through acquisition of novel genes, the recipient cell may change its ecological preference and the process could promote speciation.
This ecological preference spans much of the early history of snakes, from the branch stretching from Serpentes to Caenophidia.
However, additional supporting evidence, such as morphology, geographic range, ecological preference, chemistry, etc., will be required to establish robust species boundaries among the recently derived lineages.
