TL;DR: There may be more than one causative factor selecting for nurse-protégé interactions in arid and semi-arid environments, and hypotheses of potential causative forces that might have selected for such interactions in the arid zones such as seed trapping, nutrient, moisture, protection from browsing or trampling and support availability are explored.

TL;DR: It has been reported that species from environments where seedlings are prone to drought during establishment tend to have larger seeds, and one proposed reason for this is that larger-seeded species might be able to allocate a larger proportion of mass to roots rather than shoots during early growth.

TL;DR: A broad test of the hypothesis that invasions are better predicted by a change in disturbance regime than by disturbance per se is used, using data from 200 sites around the world to provide a broad test.

TL;DR: This study investigated the hypothesis that elaiosomes on seeds have converged in composition and attractiveness with the insect prey of ants, and the response of six ant species to the diglyceride 1,2-diolein was compared.

TL;DR: The results do not support the hypothesis that tropical plants have higher levels of resistance traits than do plants from higher latitudes, and if anything, plants haveHigher resistance toward the poles.
