Plant traits associated with alien invasiveness may also distinguish rare from common native species. To test this, we grew 23 native (9 common, 14 rare) and 18 alien (8 common, 10 rare) herbaceous species in Switzerland from six plant families under nutrient-addition and competition treatments. Alien and common species achieved greater biomass than native and rare species did overall respectiv...

Pseudogenes have been defined as nonfunctional sequences of genomic DNA originally derived from functional genes. It is therefore assumed that all pseudogene mutations are selectively neutral and have equal probability to become fixed in the population. Rather, pseudogenes that have been suitably investigated often exhibit functional roles, such as gene expression, gene regulation, generation o...
