Geometric morphometric analyses were conducted on cultured populations of five Micrasterias species (M. crux-melitensis, M. papillifera, M. rotata, M. thomasiana, M. truncata). The patterns in the morphological variation measured using the morphospaces spanned by a PCA of morphometric data for individual populations were compared. In addition, the 18S rDNA sequences of these species are reporte...

Sixteen strains designated Mycobacterium farcinogenes, fifteen Mycobacterium senegalense, and ten Nocardia farcinica were, together with strains of Mycobacterium and Nocardia, subjected to numerical phenetic analyses using 96 unit characters. The data were examined using the simple matching (SSM), Jaccard (SJ) and pattern (DP) coefficients and clustering achieved using the unweighted average li...

Similar DNA homology values were recorded when a modified S1 nuclease technique and a standard nitrocellulose membrane filter method were applied to representative strains of Rhodococcus. The DNA homology data showed that R. globerulus, R. luteus and R. sputi form distinct genomic species. The congruence between the DNA homology and earlier numerical phenetic data was good, but there was eviden...

a phenetic analysis of the 12 taxa or operational taxonomic units (otus) belonging to the three sections; genea, neobromus, and nevskiella of the genus bromus was performed. unweighted pair-group method using arithmetic averages (upgma) and weighted pair-group method using arithmetic averages (wpgma) clustering and factoriel method analyses were used to set the taxa apart. forty-four characters...

Abstract. Kandowangko NY, Febriyanti. 2023. Genetic diversity of the genus Citrus in Tomini Bay coastal areas, Indonesia based on morphological characters. BIodiversitas 24: 2938-2952. plants are one fruit that widely consumed by community, both for food, health, and customs. The existence area only grows wild has not been cultivated intensively. Lack information citrus use balanced with cultiv...

Lichen of the genus Usnea is quite common being used as a traditional herbal remedy. This characterized by thallus, which very similar among species, leads to some difficulties in distinguishing them. In Indonesia, such research report on availability this based their morphological characteristic minimal. might be due too high similarities The molecular character, DNA Barcode Internal Transcrib...

The diversity of freshwater zooplankton is still little known in Mexico, particularly reference to insular communities. Diaptomid copepods (Crustacea: Copepoda: Calanoida) are a widespread group worldwide, and Mexico harbours high diaptomid diversity. Based on recent sampling Caribbean Island we present the first record copepod from an island ecosystem. It shows well-known tendency Neotropical ...

The Chromolaena congesta complex (Asteraceae, Eupatorieae) presents a difficult challenge for biodiversity researchers due to the intertwined connections of its species and difficulty establishing morphological boundaries. In this study, we aimed use morphometric analyses evaluate delimitation taxa belonging C. complex, identify informative traits understand identity several “atypical” specimen...
