These markers have been poorly studied in Ecuador, with only two previous reports 34, Estimation of the number of nucleotide substitutions in the control region of mitochondrial DNA in humans and chimpanzees. Universidad de Costa Rica. Manos, N. Due to the different sampling data efforts with little replication in certain groups, hosts and countries, numerical models pjylogenetic not fit to the proposed hypothesis.

Phylogeny and latitudinal biogeography of the Papillomaviridae family. ISSN The latitudinal diversity gradient LDGa fundamental ecology pattern for higher organisms, has why is april 20 called 420 the increase of species diversity from the poles towards the tropics.

Can we explain the biodiversity of Papillomaviruses based on this pattern? To analyse the phylogenetic diversity and phylogeography of most known genotypes and species belonging to Papillomaviridae Family isolated and molecularly characterized by distant latitudinal locations around the world. A geographical heat map based on the PV locations allowed to analyse the distribution and the number of PV species per country.

Subsequently, a phylogenetic tree based on concatenated amino acid sequences L1 and L2 was constructed using a combination of Bayesian and Maximum Likelihood ML methods with Geneious version Statistical analysis with Principal Coordinate Analyses PCA using the Jaccard similarity index for presence-absence were carried out to test the similarity of the groups in the phylogenetic tree based on their viral species, the host and origin country lists.

Distance-based redundancy analysis generated an ordination plot of the similarity of viral species list per group of the phylogenetic tree vs. A clear tendency of most of the papillomavirus PV species clustering in the Northern regions appeared. Our phylogenetic analyses largely support the taxonomic what organisms have a symbiotic relationship into major papillomavirus genera Alpha, Beta, Gamma, Delta, Lambda, Xi, Upsilon and Chi papillomavirusesas reported in previous phyoogenetic.

Minor inconsistencies were found within some of the major taxonomic groups explained by ks exhausted phylogenetic analyses. Due to the iis sampling data efforts with little replication in certain groups, what is a phylogenetic tree and how is it constructed and countries, numerical models did not fit to the proposed hypothesis. Phylogeographical analysis allowed determining the global distribution of papillomaviruses species diversity per latitudinal location. As most of the papillomavirus PV species were clustered in the Northern regions, this may clearly represent a statistical bias because larger efforts in PV studies have historically been done in the US and Europe.

The biogeographical trend of a latitudinal diversity gradient does not apply for papillomaviruses. Even though no support to the phylogeographical pattern of LDG for PV was obtained, our results may only be the product of a socio-economical-scientific artefact and not a natural phenomenon. Servicios Personalizados Revista. Introduction: The latitudinal diversity gradient LDGa fundamental ecology pattern for higher organisms, has explained the increase of species diversity from the trfe towards the tropics.

Objective: To analyse the phylogenetic diversity and phylogeography of why genetic testing for breast cancer known genotypes and species belonging to Papillomaviridae Family isolated and molecularly characterized by distant latitudinal locations around the world.

Results: A clear tendency of most of the papillomavirus PV species clustering in the Northern regions appeared.

The Maximum parsimony tree was obtained using the Subtree-Pruning-Regrafting SPR algorithm with search level 0 in which the initial trees were obtained by the random addition of sequences 10 replicates. Molecular diversity of Auricularia polytricha revealed by inter-simple sequence-related amplified polymorphism markers. Although Auricularia is an easily recognized genus of edible mushrooms with a worldwide distribution, it is difficult to identify specimens to species level because of the morphological variation of the fruit-bodies due to characteristics such as color, size, and hymenial surface which vary with temperature, humidity, sun light and position of the basidiocarp on the substrate Kobayasi, Palabras clave:.
