Grazing by large herbivores has the potential to facilitate invasion of natural grasslands by non-native plant species. It is expected that both herbivore identity and plant community type modulate the effect. The objective ...

The long-term influence of persistent small herbivores on successional plant community configuration is rarely studied. We used a herbivore exclusion experiment along the successional gradient in a salt-marsh system, to ...

Top-down control by large herbivores is a well-known driver of plant diversity structure and productivity. Yet, for forest ecosystems the sign and magnitude of herbivore control across resource gradients is not well ...

1. In a recently published paper, Oliva et al. concluded that domestic grazing pressure across Patagonian rangelands approached carrying capacity due to decades of stock adjustment, but that guanaco overpopulation may have ...

Both bottom-up (e.g., nutrients) and top-down (e.g., herbivory) forces structure plant communities, but it remains unclear how they affect the relative importance of stochastic and deterministic processes in plant community ...

Tropical forests hold some of the world's most diverse communities of plants. Many populations of large-bodied herbivores are threatened in these systems, yet their ecological functions and contribution towards the maintenance ...

The world’s terrestrial biomes are broadly classified according to the dominant plant growth forms that define ecosystem structure and processes. Although the abundance and distribution of different plant growth forms can ...

This work focuses on the structural defenses of the two dominant spiny shrub species of the Patagonian shrub-grass steppe. We compared the amount of structural defenses (spines and thorns) of Mulinum spinosum (Cav.) Pers. ...
