The Livingstone Mountains (LM; also known as the Kipengere Range) found in southwestern Tanzania at the northern end of Lake Nyasa are an important region for understanding the biogeography of Eastern Africa. The two branches of the East African Rift Valley meet here and the mountains might represent stepping stones for colonization and migration b...
Aim
Assessment of phylogenetic diversity and biogeographical affinities of the rodent fauna from one of the most neglected areas in Africa.
Location
Angola (with biogeographical implications in adjacent areas).
Methods
Inference of mitochondrial phylogenies for rodent genera occurring in Angola, delimitation of molecular operational taxonomic uni...
The geological and geographical settings of the Eastern Mediterranean have resulted in complex patterns of intraspecific diversifications and phylogeographical histories that can be observed in squamates. In this study, we examined genetic differentiation of the Collared dwarf racer (Platyceps collaris) using a multilocus genetic dataset with a sam...
Aim
Deserts are generally perceived as areas of low diversity, and hence receive little attention from researchers and conservationists. Squamates are the dominant group of vertebrates in arid regions, and as such represent an ideal model to study biodiversity patterns in these areas. We examine spatial patterns of diversity, evolutionary history a...
Comparación de 12 kits de extracción de ADN de muestras de vertebrados
Obtener extracciones de ADN de buena calidad es un paso crucial para los proyectos de investigación del ámbito de la biología molecular. En la actualidad, existen numerosos protocolos para la extracción en tejidos de vertebrados. En el presente estudio comparamos 11 protocolos d...
Along the advantage of molecular genetic methods within the zoological research an increased need of methodical guide that summarizes all the essential information appeared including instructions about sampling of biological material from different kind of organisms and following molecular analysis.
In the first part of this guide, proper collecti...
This critical catalogue from the “The Age of Genes” exhibition presents readers with the comprehensive development of molecular phylogenetic and taxonomic research conducted at the National Museum. The reader will thus become acquainted with the Natural History Museum, which is part of the National Museum, and within which modern molecular genetic...
The family of sheath-tailed bats (Emballonuridae) constitutes a considerable part of the bat fauna of the Middle East. This region on the crossroad of three biogeographical realms represents the sole significant extension of the family range into the Palaearctic, otherwise the family is distributed mostly in the tropics. Three emballonurid species...
Background:
Spiny mice of the genus Acomys are distributed mainly in dry open habitats in Africa and the Middle East, and they are widely used as model taxa for various biological disciplines (e.g. ecology, physiology and evolutionary biology). Despite their importance, large distribution and abundance in local communities, the phylogeny and the s...
Murid rodents (Rodentia: Muridae) represent the most diverse and abundant mammalian family. In this study, we provide a refined set of fossil calibrations which is used to reconstruct a dated phylogeny of the family using a multilocus dataset (six nuclear and nine mitochondrial gene fragments) encompassing 161 species representing 82 murid genera f...
Despite the high degree of biological diversity in the Zambezian region, little information is available regarding the evolutionary history of its biota, and this is especially true for the fauna and flora of non-forested habitats. Here we use the most comprehensive multi-locus genetic dataset available to (1) reconstruct the phylogeny of spiny mic...
Small terrestrial mammals and their biogeographical affinities were studied on Mount Kitumbeine, one of the little known volcanoes in the Gregory Rift Valley (northern Tanzania). In June, 2015, a total of 10 species, two insectivores and eight rodents, were recorded during a short-time sampling in two high altitude habitats. Taxonomic identificatio...
Murid rodents (Rodentia: Myomorpha: Muroidea: Muridae) represent the most diverse and abundant mammalian group. In this study, we reconstruct a dated phylogeny of the family using a multilocus dataset (six nuclear and nine mitochondrial gene fragments) encompassing 160 species representing 82 distinct murid genera from four extant subfamilies (Deom...
Aim
The rodent genus Gerbilliscus is widespread in savannas throughout sub-Saharan Africa. The eastern clade comprises four species with distributions centred in the Somali-Masai biogeographical region of East Africa. We investigated the genetic diversity of the group with a view to illuminating the historical (Plio-Pleistocene) processes that for...
Grammomys are mostly arboreal rodents occurring in forests, woodlands and thickets throughout sub-Saharan Africa. We investigated whether the divergence events within the genus follow the existing evolutionary scenario for the development of African forests since the late Miocene. Sub-Saharan African forests and woodlands. We inferred the molecular...
We explore diversity of African pouched mice, genus Saccostomus (Rodentia, Nesomyidae), by sampling molecular and morphological variation across their continental-scale distribution in southern and eastern African savannahs and woodlands. Both mitochondrial (cytochrome b) and nuclear DNA (IRBP, RAG1) as well as skull morphology confirm the distinct...
In this study we report findings in roosting ecology, ectoparasites, echolocation characteristics and the phylogenetic position of Cardioderma cor, an impressive bat species that is distributed throughout the savannas and woodlands of eastern Africa. For individuals caught in Mago National Park, Ethiopia, we recorded broadband frequency-modulated u...
Human visceral (VL, also known as Kala-azar) and cutaneous (CL) leishmaniasis are important infectious diseases affecting countries in East Africa that remain endemic in several regions of Ethiopia. The transmission and epidemiology of the disease is complicated due to the complex life cycle of the parasites and the involvement of various Leishmani...
Background
Rodents of the genus Mus represent one of the most valuable biological models for biomedical and evolutionary research. Out of the four currently recognized subgenera, Nannomys (African pygmy mice, including the smallest rodents in the world) comprises the only original African lineage. Species of this subgenus became important models fo...

Dear all,
I try to prepare species delimitation..I am using different approaches and I would like to do genetic distances. My dataset has around 500 seqs separated approximately in 30 groups..I prepare nice matrix in MEGA, but this software work only with first 10 groups! Could you recommend me some other software, which can compute distances for groups?? Thanks!
Do you have experience with extraction DNA from lichens and myxomycetes?
I am using micro Plant extraction kit (Zymo), but success rate is very low. My starting material is very small...and I am fighting with elution step...I try incubation, incubation with Polymerase K, freezing in -80°C ant then disrupt it with pellets and put warm lysis buffer...I din't use beads with Magnalyser, because the material is so small... Do you have any advice?? THANKS IN ADVANCE!!
I would like to prepare haplotype file for phylogenetic analysis. Because I need to know each ID to belong to which haplotype I used DNAsp. But the results are not consistent. After removing some seqs the haplotypes and rerun, I get totally different results and suprisingly much haplotypes. Did I something wrong? or it is problem of DNAsp? Do you know some better software? Thanks :)
