The status of a putative new species of Lepidosperma from the mountains of south-western Tasmania, Australia, was investigated. Phenetic analysis (Flexible UPGMA Agglomerative Hierarchical Fusion and semi-strong hybrid multidimensional scaling) was conducted on a database derived from morphological and anatomical characters scored from herbarium material, culm anatomy slides and scanning electr...

Durian (Durio spp.) is a germplasm with relatively high species diversity, an estimated 27 worldwide. However, the existence of several has been threatened. This study aimed to reconstruct DNA barcode durian and its relatives analyze genetic diversity relationship based on internal transcribed spacer (ITS) region. Sixteen sequences durians ITS were collected from GenBank (NCBI) analyzed in sili...

Phase 4: Hierarchical Clustering on Probability Graph  Similarity measure: puv values from 3 rd phase  Linkage Criterion: UPGMA Phase 3: Computing the Probabilities  Given an interaction graph, GI(V, E, W), and a group interaction graph, GGI(V, Eˊ, Wˊ), we construct a probability graph GP(V, EUEˊ, P), where each weight puv ε P represents probability between vertices u and v to belong in the ...

This paper reports a simulation study comparing and evaluating the performance of different linguistic phylogeny reconstruction methods on model datasets for which the true trees are known. UPGMA performed least well, then (in ascending order) neighbor joining, the method of Gray & Atkinson and finally maximum parsimony. Weighting characters greatly improves the accuracy of maximum parsimony an...

Methods Thirty-three sampling sites were located from 0 to 2400 m a.s.l. on Crete, and sampled using pitfall traps. Material from the high-activity period of Gnaphosidae (mid-spring to mid-autumn) was analysed. Sampling sites were divided into five altitudinal zones of 500 m each. Statistical analysis involved univariate statistics (anova) and multivariate statistics, such as multidimensional s...

O objetivo desse trabalho foi avaliar e determinar os descritores morfológicos de acessos ipeca. Foram avaliados 66 ipeca conservados in vivo na Embrapa Amazônia Oriental, em Belém, PA, totalizando 330 indivíduos, para cinco caracteres quantitativos. Os dados foram submetidos as analises multivariadas, realizado a seleção direta com reanálise agrupadas dois métodos base distância Euclidiana méd...

The present study carried out to with a view characterize and validate the RAPD marker’s genetic diversity at morphological molecular levels in thirty cultivars of onion (Allium cepa L.). This work aimed determine their important traits, DNA polymorphism decipher variation. agro-morphological characters such as germination percentage, plant height, leaf colour, waxiness, foliage attitude, bulk ...

Within and among population genetic diversity of 37 Guizotia abyssinica populations from Ethiopia were analyzed using inter simple sequence repeats (ISSRs). Five primers amplified a total of 118 genomic DNA fragments across a total of 370 individuals of which 106 were polymorphic (89.83%). The average number of polymorphic bands per primer was 21.2. More bands were generated by primer UBC 888 (...

Reconstruction of evolutionary relationships from noncontemporaneous molecular samples provides a new challenge for phylogenetic reconstruction methods. With recent biotechnological advances there has been an increase in molecular sequencing throughput, and the potential to obtain serial samples of sequences from populations, including rapidly evolving pathogens, is fast being realized. A new m...
