Other claims from this paper (12)
- Intervention effect C. maculosa biomass was greater with mesh than membrane barriers.
- Association C. maculosa biomass varied by neighboring species only in mesh barrier pots.
- Intervention effect Native plant biomass did not vary by barrier type.
- Observation No carbon transfer from native plants to C. maculosa was detected.
- Observation No carbon transfer from C. maculosa to native plants was detected.
- Intervention effect C. maculosa had significantly more phosphorus in mesh divided pots, depending on the neighboring plant.
- Intervention effect C. maculosa phosphorus concentration was significantly higher in mesh pots with grass neighbors but not forb neighbors.
- Intervention effect Native species had more phosphorus in mesh than membrane divided pots.
- Observation Native species phosphorus concentration was higher in forbs than grasses.
- Mechanism The authors infer that C. maculosa exploits mycorrhizal symbiosis more effectively than native grassland species.
- Mechanism The authors propose phosphorus luxury consumption through extraradical hyphae, dependent on grass neighbors, as the mechanism.
- Mechanism The authors suggest mycorrhizal networks increase species access to phosphorus and explain neighbor effects.
