TL;DR: It is concluded that sex in Lodoicea is genetically determined, suggesting that lodoicea has a chromosomal sex determination system in which males are the heterogametic sex (XY) and females are homogametics (XX).

TL;DR: The results are consistent with the view that dioecy is an evolutionary dead end in flowering plants, although other scenarios for explaining reduced Ne cannot be ruled out.

TL;DR: It is shown here that Microbotryum species have evolved through frequent host shifts to moderately distant hosts, and it is shown further that accurate delimitation of parasite species is essential for interpreting cophylogeny studies.

TL;DR: In this paper, the authors focus on the reform efforts in Swiss forest policy with particular attention to the issue of forest expansion in mountain areas, and describe the relevant forest policy reform processes over the period from the year 2000 to 2012 using the Actor-Process-Event Scheme (APES), and analyze the underlying policy network.

TL;DR: The results of this study show that the sex‐determining system in Silene otites, a species related to S. colpophylla, is based on female heterogamety, a sex determination system that is unique among the Silene species studied to date.
