Other claims from this paper (13)
- Observation Desmodium cuspidatum populations declined dramatically in New England during the previous 30 to 40 years.
- Association Under high nitrogen deposition, a non-fixing species used applied nitrogen better than D. cuspidatum.
- Association Desmodium cuspidatum produced significantly more nodules when grown with the non-fixing species.
- Observation New England populations remained relatively stable in size over five years.
- Observation Survivorship of Desmodium cuspidatum individuals was high in New England.
- Observation Recruitment rates of Desmodium cuspidatum in New England were low.
- Mechanism Low reproductive success was attributed as the reason for low recruitment.
- Association Both pollen and resources limited reproductive success in New England populations.
- Observation Field germination rates of D. cuspidatum were similar to those of a common Desmodium species.
- Intervention effect D. cuspidatum seeds had highest germination when sown on the soil surface.
- Intervention effect D. cuspidatum seeds had highest germination when scarified and sterilized.
- Association Large D. cuspidatum seeds germinated at higher rates than small seeds.
- Observation Genetic diversity patterns in New England populations were similar to those elsewhere in the species range.
