Evidence for competition and cooperation among climbing plants.
A plant's best strategy for acquiring resources may often depend on the identity of neighbours.

متن کاملGrowing with siblings: a common ground for cooperation or for fiercer competition among plants?
Recent work has shown that certain plants can identify their kin in competitive settings through root recognition, and react by decreasing root growth when competing with relatives. Although this may be a necessary step in kin selection, no clear associated improvement in individual or group fitness has been reported to qualify as such. We designed an experiment to address whether genetic relat...
متن کاملCompetition and cooperation among huddling infant rats.
Huddling is expressed by infant rats and continues to be an important behavior throughout adulthood. As a form of behavioral thermoregulation, huddling is thought to play an essential role in compensating for inadequate physiological thermoregulation early in development. Infant rats, however, are capable of heat production shortly after birth using brown adipose tissue (BAT) and exhibit thermo...
