Association between native tree sapling and spiny shrub mitigates browsing damage produced by large herbivores in fire-degraded forests
Spiny shrubs can generate positive interactions with palatable trees in sites affected by abiotic and biotic stress (e.g. fire, and consumption by herbivores). The objective of this study was to assess the role of native shrubs (Berberis microphylla) in mitigating large herbivore browsing on tree sa...

Spiny shrubs can generate positive interactions with palatable trees in sites affected by abiotic and biotic stress (e.g. fire, and consumption by herbivores).
