Four raised to one equals one: A genetic approach to the Pseudolaelia vellozicola complex does not follow a math rule

open access: yesEcology and Evolution, Volume 10, Issue 11, Page 4562-4569, June 2020., 2020
Analysis of genetic structure revealed that each of the eight sample localities can be considered unique biological populations as they are highly differentiated from each other. The results are consistent with that expected for plants with insular geographical distribution.

High incidence and correlates of dioecy in the flora of the Canadian Arctic Archipelago

open access: yesArctic Science, 2017
In comparing the incidence of dioecy in North American floras, we report a strong, positive correlation with increasing latitude. Dioecy in the High Arctic is highly correlated with woodiness, as elsewhere.
