Geographical patterns of deep mitochondrial differentiation in widespread Malagasy reptiles.
Using sequences of the mitochondrial 16S rRNA gene, we reconstructed the phylogeography of six widely distributed Malagasy reptiles: two gekkonid lizard species, Phelsuma lineata and Hemidactylus mercatorius; two chameleons, the Calumma brevicorne complex, and Furcifer lateralis; and two skinks, Trachylepis gravenhorstii and Trachylepis elegans. Genetic differentiation among major haplotype lin...
متن کاملGeographical differences in maternal basking behaviour and offspring growth rate in a climatically widespread viviparous reptile.
In reptiles, the thermal environment during embryonic development affects offspring phenotypic traits and potentially offspring fitness. In viviparous species, mothers can potentially manipulate the embryonic thermal environment through their basking behaviour and, thus, may be able to manipulate offspring phenotype and increase offspring fitness. One way in which mothers can maximise offspring...
متن کاملApplication of Geographical Location Differences of the Sun- Path Diagram in Climatic Architecture
In this study, by recognizing geographical location changes of the sun-path diagram, we present a selection of sustainable architectural guidelines that influence the climatic element of sunshine. For this purpose, after the introduction of triple zones of the earth in terms of how the sun is exposed(include:Tropical, temperate and polar), the function of the earth's curvature to create geograp...
متن کاملCytotype stability, facultative apomixis and geographical parthenogenesis in Ranunculus kuepferi (Ranunculaceae)
BACKGROUND AND AIMS Asexual organisms are more widespread in previously glaciated areas than their sexual relatives ('geographical parthenogenesis'). In plants, this pattern is probably dependent on reproductive isolation and stability of cytotypes within their respective distribution areas. Both partial apomixis and introgressive hybridization potentially destabilize the spatial separation of ...
متن کاملGenetic Structure and Eco-Geographical Differentiation of Wild Sheep Fescue (Festuca ovina L.) in Xinjiang, Northwest China.
Glaciation and mountain orogeny have generated new ecologic opportunities for plants, favoring an increase in the speciation rate. Moreover, they also act as corridors or barriers for plant lineages and populations. High genetic diversity ensures that species are able to survive and adapt. Gene flow is one of the most important determinants of the genetic diversity and structure of out-crossed ...
