Other claims from this paper (10)
- Observation Allozyme variation was strongly structured among populations of the two Roridula species.
- Observation Allozyme variation among populations of the Pameridea hemipterans was less structured than among the plant populations.
- Observation Strong genetic structuring among hemipteran populations was evident only when large distances isolated the plant populations they live on.
- Association Genetic distances among plant populations were correlated with genetic distances among hemipteran populations.
- Association Genetic distances of both plants and hemipterans were better correlated with geographic distance.
- Observation In choice experiments Pameridea strongly preferred its carnivorous host plant Roridula over unrelated host plants.
- Observation Pameridea also preferred its host plant species over the closely related sister plant species.
- Mechanism Because Roridula and Pameridea differ in scale of gene flow, adaptation at the local population level is judged unlikely.
- Mechanism The restricted gene flow of both plants and hemipterans could enable adaptation at a regional level.
- Mechanism Specialization at the species level is likely to reinforce cospeciation processes in this mutualism.
