Do others really know us better?
The results suggest that it may be valuable to obtain significant-other-ratings when assessing negative emotion in patients and that the genders may differ in how others' ratings are related to the patients' health.
Two mechanisms are proposed that can switch the facilitation-competition balance: trait divergence and indirect interactions. When traits have diverged within the genus, the niche overlap is reduced and competition relaxed, thus allowing the coexistence of congeneric species. The presence of third interplayers (mycorrhizal fungi, seed dispersers, pollinators or pathogens) participating in the interaction between plants can alleviate the competition or enhance the reproduction and allow the coexistence of species that could not coexist in their absence.
