Hyraxes' songs have something rarely found in mammals: syntax that varies according to where the hyraxes live, geographical dialects in how they put their songs together.
Linguist John H. Bushman, a professor at the University of Kansas, explains this idea in the Language Arts Journal of Michigan, "Exploring the Geographical Dialects of English," stating, "Even though each person is likely to have a number of dialects.
Morphological variation is accompanied by remarkable variation in vocal behaviour: low-latitude populations exhibit individual song repertories (e.g., Costa Rica [ 25]; Ecuador, P.H. personal observation), while others (~20-40°S) show individual stereotypy and geographical dialects, which correspond with natural vegetation types, but not with subspecies designations [ 23, 26- 30].
Habitat-related geographical vocal dialects are documented from Argentina in both lineages B and C, with high levels of song differentiation found throughout northwestern and central Argentina, which is occupied by the single lineage B, and similarly differentiated songs in grassland and wooded environments in the parts of Argentina occupied by lineage C (Entre Rios, Corrientes, Buenos Aires).
These problems are complicated by geographical dispersion and dialect differences in the local Chinese immigrant community.
This tendency persists even after some Hakka people stop speaking Hakka and acquire Min natively without the direct negative interference from Hakka, and has gradually evolved into the realization in the Chiang dialect, the geographical areas of which are contiguous to the Hakka regions.
It has a loose organizational pattern that becomes apparent through longer observation periods and probably resembles a geographical distribution, for example, dialect regions in humans, rather than independent social units.
The contrast is between the idiolect of a single individual, and a dialect or language of a geographical, social, historical, or political group.
At the outset, the isolated geographical nature of Tana Toraja formed many dialects between the Toraja languages themselves.
It is the politically defined geographical border, not the intrinsic properties of the dialects, that would encourage viewing this continuum as two different languages.
He also explained that learning Chinese had to be a life-long process because there were many different dialects and variations of Chinese from different geographical regions and historical periods.
