Other claims from this paper (6)
- Observation Indigofera monophylla shows no cpDNA evidence for a high-elevation refugium.
- Observation Indigofera monophylla shows extraordinary cpDNA haplotype diversity and evidence for persistence across a widespread area.
- Observation Nuclear diversity hotspots in Petalostylis labicheoides occur in high-elevation locations and extend to low-elevation riparian areas.
- Observation Nuclear diversity hotspots in Indigofera monophylla occur in high-elevation locations and extend to low-elevation riparian areas.
- Mechanism A mesic montane refugium in P. labicheoides may be related to its preference for growth in water-gaining areas.
- Mechanism The lack of such refugium evidence in I. monophylla may be related to maintenance of cpDNA diversity in a large soil seed bank.
