Phylogeographical variation of chloroplast DNA in holm oak (Quercus ilex L.)
Molecular Ecology - Tập 11 Số 11 - Trang 2327-2336 - 2002
R. Lumaret, C. Mir, Henri-Alexandre Michaud, V. Raynal
AbstractVariation in the lengths of restriction fragments (RFLPs) of the whole chloroplast DNA molecule was studied in 174 populations of Quercus ilex L. sampled over the entire distribution of this evergreen and mainly Mediterranean oak species. By using five endonucleases, 323 distinct fragments were obtained. From the 29 and 17 cpDNA changes identified as site and length mutations, respectively... hiện toàn bộ
Combining chloroplast and nuclear microsatellites to investigate origin and dispersal of New World sweet potato landraces

Beyond the Mediterranean peninsulas: evidence of central European glacial refugia for a temperate forest mammal species, the bank vole (Clethrionomys glareolus)
Molecular Ecology - Tập 14 Số 6 - Trang 1727-1739 - 2005
Valérie Deffontaine, R. Libois, Petr Kotlı́k, Robert S. Sommer, Caroline M. Nieberding, Emmanuel Paradis, Jeremy B. Searle, J. R. MICHAUX
AbstractThis study details the phylogeographic pattern of the bank vole, Clethrionomys glareolus, a European rodent species strongly associated with forest habitat. We used sequences of 1011 base pairs of the mitochondrial DNA cytochrome b gene from 207 bank voles collected in 62 localities spread throughout its distribution area. Our results reveal the presence of three Mediterranean (Spanish, It... hiện toàn bộ
Staying out in the cold: glacial refugia and mitochondrial DNA phylogeography in ancient European brown bears
Molecular Ecology - Tập 16 Số 24 - Trang 5140-5148 - 2007
Cristina Valdiosera, Nuria Garcı́a, Cecilia Anderung, Love Dalén, Évelyne Cregut‐Bonnoure, Ralf‐Dietrich Kahlke, Mathias Stiller, Mikael Brandström Durling, Mark Thomas, Juan Luís Arsuaga, Anders Götherström, Ian Barnes
AbstractModels for the development of species distribution in Europe typically invoke restriction in three temperate Mediterranean refugia during glaciations, from where recolonization of central and northern Europe occurred. The brown bear, Ursus arctos, is one of the taxa from which this model is derived. Sequence data generated from brown bear fossils show a complex phylogeographical history fo... hiện toàn bộ
Sudden expansion of a single brown bear maternal lineage across northern continental Eurasia after the last ice age: a general demographic model for mammals?
Molecular Ecology - Tập 18 Số 9 - Trang 1963-1979 - 2009
Marju Korsten, Simon Y. W. Ho, John Davison, BERIT PÄHN, Egle Vulla, MARIS ROHT, И. Л. Туманов, Ilpo Kojola, Žanete Andersone-Lilley, Jānis Ozoliņš, Małgorzata Pilot, Yorgos Mertzanis, Alexios Giannakopoulos, ALEX A. VOROBIEV, Nikolay Markov, Alexander P. Saveljev, E. A. Lyapunova, Alexei V. Abramov, Peep Männil, Harri Valdmann, SERGEI V. PAZETNOV, VALENTIN S. PAZETNOV, ALEXANDER M. RÕKOV, Urmas Saarma
AbstractThe brown bear has proved a useful model for studying Late Quaternary mammalian phylogeography. However, information is lacking from northern continental Eurasia, which constitutes a large part of the species’ current distribution. We analysed mitochondrial DNA sequences (totalling 1943 bp) from 205 bears from northeast Europe and Russia in order to characterize the maternal phylogeography... hiện toàn bộ
Contrasting patterns of population subdivision and historical demography in three western Mediterranean lizard species inferred from mitochondrial DNA variation
Molecular Ecology - Tập 16 Số 6 - Trang 1191-1205 - 2007
Catarina Pinho, D. James Harris, Nuno Ferrand
AbstractPleistocene climatic oscillations were a major force shaping genetic variability in many taxa. We analyse the relative effects of the ice ages across a latitudinal gradient in the Western Mediterranean region, testing two main predictions: (i) species with historical distributions in northern latitudes should have experienced greater loss of suitable habitat, resulting in higher extinction... hiện toàn bộ
Comparative phylogeography and postglacial colonization routes in Europe
Molecular Ecology - Tập 7 Số 4 - Trang 453-464 - 1998
Pierre Taberlet, Luca Fumagalli, ANNE‐GABRIELLE WUST‐SAUCY, Jean‐François Cosson
The Quaternary cold periods in Europe are thought to have heavily influenced the amount and distribution of intraspecific genetic variation in both animals and plants. The phylogeographies of 10 taxa, including mammals (Ursus arctos, Sorex spp., Crocidura suaveolens, Arvicola spp.), amphibians (Triturus spp.), arthropods (Chorthippus parallelus), and plants (Abies alba, Picea abies, Fagus sylvatic... hiện toàn bộ
A simulated annealing approach to define the genetic structure of populations
Molecular Ecology - Tập 11 Số 12 - Trang 2571-2581 - 2002
Isabelle Dupanloup, Stefan Schneider, Laurent Excoffier
AbstractWe present a new approach for defining groups of populations that are geographically homogeneous and maximally differentiated from each other. As a by‐product, it also leads to the identification of genetic barriers between these groups. The method is based on a simulated annealing procedure that aims to maximize the proportion of total genetic variance due to differences between groups of... hiện toàn bộ
Chiến lược cô lập vi vệ tinh: Một đánh giá Dịch bởi AI
Molecular Ecology - Tập 11 Số 1 - Trang 1-16 - 2002
Lorenzo Zane, Luca Bargelloni, Tomaso Patarnello
Tóm tắtTrong vài năm gần đây, vi vệ tinh đã trở thành một trong những dấu ấn phân tử phổ biến nhất được sử dụng với nhiều ứng dụng trong nhiều lĩnh vực khác nhau. Độ biến thể cao và sự dễ dàng tương đối trong việc đánh giá là hai đặc điểm chính khiến vi vệ tinh rất được quan tâm trong nhiều nghiên cứu di truyền. Nhược điểm chính của vi vệ tinh là chúng cần được cô lập de novo từ các loài được nghi... hiện toàn bộ

Evolutionary genetics and biogeographic structure of Rhizobium gallicum sensu lato, a widely distributed bacterial symbiont of diverse legumes
Molecular Ecology - Tập 14 Số 13 - Trang 4033-4050 - 2005
Claudia Silva, Pablo Vinuesa, Luis E. Eguiarte, Valeria Souza, Esperanza Martínez‐Romero
AbstractWe used phylogenetic and population genetics approaches to evaluate the importance of the evolutionary forces on shaping the genetic structure of Rhizobium gallicum and related species. We analysed 54 strains from several populations distributed in the Northern Hemisphere, using nucleotide sequences of three ‘core’ chromosomal genes (rrs, glnII and atpD) and two ‘auxiliary’ symbiotic genes... hiện toàn bộ
