Local origin or external input: modern horse origin in East Asia
Springer Science and Business Media LLC - Tập 19 - Trang 1-14 - 2019
Despite decades of research, the horse domestication scenario in East Asia remains poorly understood. The study identified 16 haplogroups with fine-scale phylogenetic resolution using mitochondrial genomes of 317 horse samples. The time to the most recent common ancestor of the 16 haplogroups ranges from [0.8–3.1] thousand years ago (KYA) to [7.9–27.1] KYA. With combined analyses of the mitochondr...... hiện toàn bộ
Phylogeny and evolution of plant macrophage migration inhibitory factor/D-dopachrome tautomerase-like proteins
Springer Science and Business Media LLC - Tập 15 - Trang 1-16 - 2015
The human (Homo sapiens) chemokine-like protein macrophage migration inhibitory factor (HsMIF) is a pivotal mediator of inflammatory, infectious and immune diseases including septic shock, colitis, malaria, rheumatoid arthritis, and atherosclerosis, as well as tumorigenesis. HsMIF has been found to exhibit several sequential and three-dimensional sequence motifs that in addition to its receptor bi...... hiện toàn bộ

Ecological and genetic divergence between two lineages of Middle American túngara frogs Physalaemus (= Engystomops) pustulosus
Springer Science and Business Media LLC - Tập 10 - Trang 1-18 - 2010
Uncovering how populations of a species differ genetically and ecologically is important for understanding evolutionary processes. Here we combine population genetic methods (microsatellites) with phylogenetic information (mtDNA) to define genetic population clusters of the wide-spread Neotropical túngara frog (Physalaemus pustulosus). We measure gene flow and migration within and between populati...... hiện toàn bộ
You can't always get what you want: size assortative mating by mutual mate choice as a resolution of sexual conflict
Springer Science and Business Media LLC - Tập 9 - Trang 1-9 - 2009
Assortative mating patterns for mate quality traits like body size are often observed in nature. However, the underlying mechanisms that cause assortative mating patterns are less well known. Sexual selection is one important explanation for assortment, suggesting that i) one (usually the female) or both sexes could show preferences for mates of similar size or ii) mutual mate choice could resolve...... hiện toàn bộ
Five major shifts of diversification through the long evolutionary history of Magnoliidae (angiosperms)
Springer Science and Business Media LLC - - 2015
With 10,000 species, Magnoliidae are the largest clade of flowering plants outside monocots and eudicots. Despite an ancient and rich fossil history, the tempo and mode of diversification of Magnoliidae remain poorly known. Using a molecular data set of 12 markers and 220 species (representing >75% of genera in Magnoliidae) and six robust, internal fossil age constraints, we estimate divergence ti...... hiện toàn bộ
Muller's Ratchet and compensatory mutation in Caenorhabditis briggsae mitochondrial genome evolution
Springer Science and Business Media LLC - Tập 8 - Trang 1-13 - 2008
The theory of Muller' Ratchet predicts that small asexual populations are doomed to accumulate ever-increasing deleterious mutation loads as a consequence of the magnified power of genetic drift and mutation that accompanies small population size. Evidence for Muller's Ratchet and knowledge on its underlying molecular mechanisms, however, are lacking for natural populations. We characterized mitoc...... hiện toàn bộ
The impact of population size on the evolution of asexual microbes on smooth versus rugged fitness landscapes
Springer Science and Business Media LLC - Tập 9 - Trang 1-10 - 2009
It is commonly thought that large asexual populations evolve more rapidly than smaller ones, due to their increased rate of beneficial mutations. Less clear is how population size influences the level of fitness an asexual population can attain. Here, we simulate the evolution of bacteria in repeated serial passage experiments to explore how features such as fitness landscape ruggedness, the size ...... hiện toàn bộ
Erratum to: Chromosomal evolution of the PKD1gene family in primates
Springer Science and Business Media LLC - Tập 9 - Trang 1-1 - 2009
Correction to Kirsch S, Pasantes J, Wolf A, Bogdanova N, Münch C, Pennekamp P, Krawczak M, Dworniczak B, Schempp W: Chromosomal evolution of the PKD1 gene family in primates. BMC Evolutionary Biology 2008, 8:263 (doi:10.1186/1471-2148-8-263)
Extreme genetic diversity in the lizard Atlantolacerta andreanskyi(Werner, 1929): A montane cryptic species complex
Springer Science and Business Media LLC - Tập 12 - Trang 1-19 - 2012
Atlantolacerta andreanskyi is an enigmatic lacertid lizard that, according to the most recent molecular analyses, belongs to the tribe Eremiadini, family Lacertidae. It is a mountain specialist, restricted to areas above 2400 m of the High Atlas Mountains of Morocco with apparently no connection between the different populations. In order to investigate its phylogeography, 92 specimens of A. andre...... hiện toàn bộ
