Phylogeography and Phylodemography
The Bryologist, 2002Abstract Phylogenetic analyses of infraspecific molecular data in relation to geographic and ecological information has come to be known as phylogeography. Bryophytes offer fertile material for such analyses, which can help clarify long standing biogeographic questions that were intractable before molecular data became available.

The Phylogeography of African Brazilians
Human Heredity, 2007<i>Background/Aims:</i> Approximately four million Africans were taken as slaves to Brazil, where they interbred extensively with Amerindians and Europeans. We have previously shown that while most White Brazilians carry Y chromosomes of European origin, they display high proportions of African and Amerindian mtDNA lineages, because of sex ...

Population Genomics and Phylogeography
2019Population genetics is the study of genetic variation within populations and how allele frequencies change over space and time. This field largely focuses on the five fundamental evolutionary processes that influence genetic variation: mutation, genetic drift, gene flow, natural selection, and recombination.

East Asian Ethnolinguistic Phylogeography
Bulletin of Chinese Linguistics, 2013A polyphyletic understanding of Asian linguistic diversity was first propagated in 1823. Since 1901, various scholars have proposed larger linguistic phyla uniting two or more recognised Asian language families. The most recent proposal in this tradition, Starosta’s 2001 East Asian phylum, comprising the Trans-Himalayan, Hmong-Mien, Austroasiatic ...

Phylogeography of Ticks (Acari: Ixodida)
Annual Review of Entomology, 2019Improved understanding of tick phylogeny has allowed testing of some biogeographical patterns. On the basis of both literature data and a meta-analysis of available sequence data, there is strong support for a Gondwanan origin of Ixodidae, and probably Ixodida.

Abstract Linguistic phylogeography is concerned with the reconstruction of the geographical distribution of lineages pertaining to a specific language family (phylogeny). This chapter reviews both traditional methods and modern computational ones. The computational methods draw upon information from the range of languages in a phylogeny,
