Stress-gradient hypothesis and plant distribution along ecotonal gradients
(Wiley Blackwell Publishing, Inc, 2018-11)
The stress-gradient hypothesis (SGH) predicts that, although facilitation and competition occur together, facilitative interactions will be more prevalent with increasing abiotic stress. In water-limited ecosystems, support ...
Testing the role of biotic stress in the stress gradient hypothesis. Processes and patterns in arid rangelands
(Wiley Blackwell Publishing, Inc, 2011-06)
Since many arid ecosystems are overstocked with domestic herbivores, biotic stress could have a stronger influence in modulating the balance of species interactions than expected from the stress gradient hypothesis (SGH). ...
Plant–plant facilitation increases with reduced phylogenetic relatedness along an elevation gradient
(2020)
Environmental conditions can modify the intensity and sign of ecological interactions. The stress gradient hypothesis (SGH) predicts that facilitation becomes more important than competition under stressful conditions. To ...
Benefit of shading by nurse plant does not change along a stress gradient in a coastal dune
(Public Library of ScienceSan Francisco, 2014-08)
The proximity of adult neighbors often increases the performance of woody seedlings under harsh environmental conditions but this nurse plant effect becomes less intense when abiotic stress is alleviated, as predicted by ...
Plant-plant facilitation increases with reduced phylogenetic relatedness along an elevation gradient
(Wiley, 2020)
Environmental conditions can modify the intensity and sign of ecological interactions. The stress gradient hypothesis (SGH) predicts that facilitation becomes more important than competition under stressful conditions. To ...
Determinantes de los ensambles de arbustos del Desierto Costero de Atacama
(2019)
Species coexistence depends on two non-mutually exclusive assembly processes, the abiotic filter and biotic interactions. The influence of these two processes varies according to the spatial scale, being abiotic filter ...
