Complex biotic interactions mediated by shrubs: revisiting the stress-gradient hypothesis and consequences for tree seedling survival

Arthur Guignabert, Laurent Augusto, Maya Gonzalez, Christophe Chipeaux & Florian Delerue
1. Using nurse shrubs to improve tree seedling establishment in stressed environments is a common practice in forestry. Recent refinements of the stress-gradient hypothesis suggest that positive nurse effects occur under intermediate stress and decline in the harshest conditions. Additionally, indirect facilitation is expected in low-stressed/productive systems according to the initial stress-gradient hypothesis. However, there have been fewer investigations into the use of nurse shrubs to decrease herbivore impacts in stressed systems compared with the...
