Evidence for clonal integration of clones contributing to unexpectedly higher benefits for interspecific neighbours.

Clonal plants benefit from the ability to translocate resources among interconnected ramets to colonize stress habitats. Despite the fact that the physiological integration of clones may influence their general performance and competitiveness, we still lack an understanding of how integration alters the ability of clones to compete with their neighbours. In a greenhouse experiment, we investigated how clonal integration of a perennial herbaceous Cynodon dactylon, which originated from two flooding stress ecotypes, influenced the growth, functional traits, biomass allocation and relative competitiveness of their intraspecific and interspecific neighbours.

Affective norms for 501 Chinese words from three emotional dimensions rated by depressive disorder patients.

Introduction: Emotional words are often used as stimulus material to explore the cognitive and emotional characteristics of individuals with depressive disorder, while normal individuals mostly rate the scores of affective words. Given that individuals with depressive disorder exhibit a negative cognitive bias, it is possible that their depressive state could influence the ratings of affective words. To enhance the validity of the stimulus material, we specifically recruited patients with depression to provide these ratings.
