TL;DR: Testing whether the S. latifolia Y chromosome is undergoing genetic degeneration by analyzing seven sex-linked genes detects signs of degeneration in most of the Y- linked gene sequences analyzed, similar to those of animal Y-linked and neo-Y chromosome genes.

TL;DR: Investigation of a group of food‐deceptive Mediterranean orchids from the genera Anacamptis, Neotinea, and Orchis reveals that intrinsic postzygotic isolation strongly contributes to maintaining species boundaries among Mediterranean food‐ deceptive orchid while establishing a prominent role for these reproductive barriers in the early stage of species isolation.

TL;DR: The discipline of molecular ecology has undergone enormous changes since the journal bearing its name was launched approximately two decades ago as discussed by the authors, and the field has seen great strides in analytical methods development, made groundbreaking discoveries and experienced a revolution in genotyping technology.

TL;DR: Analyzing the structure of two natural hybrid zones between Silene latifolia and Silene dioica in the Swiss Alps revealed that morphology in this study system is useful for identifying hybrids, but not for detailed analysis of hybrid zone structure.

TL;DR: It is found that exposure to heat stress in previous generations accelerated flowering under G4 control conditions in Sha-0, but heritable effects disappeared in G5 after two generations without stress exposure, indicating that stress can induce heritable, potentially adaptive phenotypic changes, probably through epigenetic mechanisms.
