Phylogeography endeavors to understand the processes that underlie the geographical distribution of genetic variation within and among closely related species. This chapter explains what phylogeography is and presents methodological and conceptual developments in this field.

Annual Review of Ecology, Evolution, and Systematics, 2009
Phylogeography's objective—to understand the processes underlying the spatial and temporal dimensions of genetic variation—underlies both the prominence and extensive methodological transformations that characterize this nascent field. Here I discuss the insights that come from detailed demographic information and how an understanding of ...

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.

Extending phylogeography to account for lineage fusion
Journal of Biogeography, 2019Secondary contact between long isolated populations has several possible outcomes. These include the strengthening of preexisting reproductive isolating mechanisms via reinforcement, the emergence of a hybrid lineage that is distinct from its extant ...

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 ...

A Greek Cylindrospermopsis raciborskii strain: Missing link in tropic invader's phylogeography tale.
Harmful Algae, 2018The cyanobacterium Cylindrospermopsis raciborskii represents a challenge for researchers and it is extensively studied for its toxicity and invasive behaviour, which is presumably enhanced by global warming.

Journal of Biogeography, 2018
The Rosalia longicorn (Rosalia alpina) is an internationally protected icon of biodiversity associated with old trees and dead wood. Although the beetle regularly exploits several marginal hosts, its preferred main host is European beech (Fagus sylvatica
