Other claims from this paper (19)
- Association Rarity was unrelated to taxonomic status or geographical distribution.
- Association Rainfall, temperature and elevation differed significantly between common and rare species.
- Association Resprouting ability and plant size differed significantly between common and rare species.
- Association Rare species tended to have fewer plants per patch than common species.
- Observation Current Sydney region distributions appear to reflect historical patterns more than recent fragmentation.
- Observation Genetic variation was low in all four species.
- Association Rare species had significantly greater within-population genetic variation than common species.
- Observation Genetic structure was significant among species at 21percent.
- Observation Genetic structure was significant among populations at 15percentage.
- Association Interpopulation variation did not vary consistently with rarity across the two species pairs.
- Association Rare species showed greater differentiation between populations than common species after accounting for geographic separation.
- Association Common species had fruit maturation above 35%, versus below 20% in rare species.
- Association Only rare species were pollen-limited, with lower open-pollinated fruit set than hand-crossed fruit set.
- Observation Native bees and introduced honeybees visited flowers of all species.
- Association Native bees visited fewer flowers per plant and moved farther between plants than honeybees.
- Association Native bees visited common species more often than rare species.
- Association Macropod seed removal exceeded 50% in common species and was below 25% in rare congeners.
- Association Rodent seed predation had no overall rarity effect, but rare P. mollis maxima seeds were eaten more than seeds of the other three species.
- Recommendation Authors recommend prioritizing conservation of all rare obligate-seeding Persoonia populations in the wild.
