The phrase "ancestral range" is correct and usable in written English.
It can be used in contexts discussing the historical or geographical area associated with ancestors or a species' original habitat.
Example: "The researchers studied the ancestral range of the species to understand its migration patterns over the centuries."
Alternatives: "historical range" or "native range".
We used BioGeoBEARS117 in R version 3.5.0118 to estimate ancestral range of Cyrtognatha in the Caribbean.
We estimated the ancestral range of species with all models implemented in BioGeoBEARS: DEC (+J), DIVALIKE (+J) and BAYAREALIKE (+J).
In this analysis, the majority of species most closely related to the Galápagos finches were found to have their ancestral range in the Caribbean.
Ancestral range estimation suggested that modern lowland antpittas probably originated in the Amazonian Sedimentary basin during the middle Miocene, and that most lineages within the Hylopezus/Myrmothera clade appeared in the Plio-Pleistocene.
The reconstructed distribution of the warblers at the present time (Fig. 1A) corresponds well with their known distribution, permitting confidence in ancestral range reconstructions.
Also, complete extinction events, in which a lineage disappears from the entire ancestral range, or full dispersal events, in which one lineage leaves the ancestral range to colonize a different area without speciating, cannot be inferred with event-based methods because these events do not leave a trace in the phylogeny.
We combined the ancestral-range sexual with ancestral-range clonal lineages to increase the power of the statistical test.
We found that ancestral-range sexuals had much lower probability of reproduction compared to both invasive and ancestral-range clonal lineages (Fig. 2B).
The invasive lineages survive poorly at the lowest salinity where the ancestral-range clones do well.
The design used in this paper was a comparison of invasive and ancestral-range genotypes.
It is possible that the invasive clones already had the observed plasticity in the ancestral-range.
