The effect of livestock grazing on plant diversity and productivity of mountainous grasslands in South America – A meta‐analysis

Ana Patricia Sandoval‐Calderon e outros, 2024 · Ecology and Evolution

Livestock exclusion in South American mountain grasslands significantly decreased plant species richness by a log response ratio of -0.14.

Trecho do estudo
The meta‐analysis showed that overall, herbivore exclusion decreased species richness (mean and 95% CIs = −0.14 (−0.25, −0.02))

Contexto

What changed: Experimental plots excluded mammalian livestock herbivores using fences. Comparison: Naturally grazed grassland plots. Limits: Small number of available studies in Andean ecosystems, with most experiments lasting only a few years (median duration 2 years).
