Other claims from this paper (7)
- Observation The Rio Negro has not been a barrier to gene flow by pollen and seeds for either Caryocar species.
- Observation No genetic differentiation was detected between the left and right banks of the Rio Negro for C. villosum and C. microcarpum.
- Observation Six trnL haplotypes were identified in C. microcarpum.
- Observation Seven psbA-trnH haplotypes were identified in C. microcarpum.
- Observation Only one haplotype was found in C. villosum for both sequences.
- Observation A recent expansion of one maternal lineage of C. villosum from a relic population may be indicated.
- Mechanism Contrasting environments colonized by the congener pair may have shaped the genetic structure of both species.
