A study finds that four Quercus species adapted to arid and semi-humid climates still produce recalcitrant seeds.
Root foraging and yield in maize/bean/squash polycultures
One cause of the yield advantage in the ‘three sisters’ polyculture is that the crops have different, possibly complementary, root foraging strategies.
