Mimosa pudica is the most abundant and problematic invasive species in tropical pastures. This study investigates the effects of two cattle grazing systems, long-term moderate grazing (LTG, 2.7 animal unit/ha/yr for 33 years) and short-term heavy grazing (STG, 5 animal unit/ha/yr for 2 years) compared with ungrazed exclosure pasture on the invasion of M. pudica and its relationship with herbage...
Abstract Rainfall and irrigation trigger large pulses of the powerful greenhouse gas N 2 O from intensively managed pastures, produced via multiple, simultaneously occurring pathways. These can account for a fraction total losses, demonstrating importance to determine magnitude source partitioning under these conditions. This study investigated response different pathways production wetting acr...
Pasture ecosystems may be particularly vulnerable to land degradation due to the high risk of human disturbance (e.g., overgrazing, burning, etc.), especially when compared with natural ecosystems (non-pasture, non-cultivated) where direct human impacts are minimal. Using maximum annual leaf area index (LAImax) as a proxy for standing biomass and peak annual aboveground productivity, we analyze...
