Typical Colour

Specimens of Bipalium adventitium (Platyhelminthes, Geoplanidae) were found in Montréal, Québec, Canada. The specimens showed the typical colour pattern of the species and barcoding (Cytochrome Oxidase I) demonstrated near-identity with a sequence of the same species from the USA. This is the first record of the species in Canada.

Neocaridina davidi (Bouvier, 1904) is an exotic freshwater shrimp originating from Asia and often kept as a pet in amateur aquarium cultures. Herewith, we report on the second finding of N. davidi in fresh waters of Europe and the first discovery of that species both in Poland and in Central Europe. The species was found in samples collected in 2003, 2013 and 2017 in the thermally polluted canal connected to the River Oder, south of Gryfino, in the vicinity of the Dolna Odra Power Plant. The taxonomic identity of the collected shrimp was confirmed by the standard DNA barcoding procedure, using a 610 bp-long fragment of cytochrome oxidase I (COI). The findings spanning more than a decade suggest that N. davidi may have established a self-reproducing population at this site. Following the finding of Atyaephyra desmarestii (Millet, 1831) in 2000, Neocaridina davidi is the second freshwater shrimp species found in the River Oder and in Poland.

Most mitochondrial genes are transcribed as a single large transcript from the heavy strand of mitochondrial DNA, and are subsequently processed into the proximal mitochondrial (mt) 12 S and 16 S rRNAs, and the more distal tRNAs and mRNAs. We have shown that in intestinal epithelial biopsies the steady-state levels of mt 12 S and 16 S rRNA are an order of magnitude greater than those of mt mRNAs. Fractionation of rat small intestinal epithelial cells on the basis of their maturity has shown that the greatest ratios of 12 S mt rRNA/cytochrome b mt mRNA or 12 S mt rRNA/cytochrome oxidase I mt mRNA are found in the surface mature enterocytes, with a progressive decrease towards the crypt immature enteroblasts. Cytochrome b and cytochrome oxidase I mt mRNA levels are relatively uniform along the crypt-villus axis, but fractionation experiments showed increased levels in the crypt base. The levels of human mitochondrial transcription factor A are also greater in immature crypt enteroblasts compared with mature villus enterocytes. These results show that the relative levels of mt rRNA and mRNA are distinctly regulated in intestinal epithelial cells according to the crypt-villus position and differentiation status of the cells, and that there are higher mt mRNA and mt TFA levels in the crypts, consistent with increased transcriptional activity during mitochondrial biogenesis in the immature enteroblasts.

Grouper fish (Serranidae) is a type of fish found in Indonesian waters. However, not many people have conducted further research on phylogenetics based on COI (Cytochrome Oxidase I). This study aims to explain the phylogeny of grouper fish from the Serranidae family based on COI (Cytochrome Oxidase I). This research is a literature study. The research samples were grouper fish from Lombok, Karimunjawa, Lampung, Kendari, Madura, Tanakeke, and Numfor. The research instrument was a grouper-type observation sheet and an observation sheet for the results of the MEGA 7 application test. The data were analyzed using qualitative descriptive analysis. The results showed that the level of kinship between the species tested was very close, including Epinephelus areolatus, E. merra, E. fasciatus, E. longispinis, E. coioides, E. ongus, and E. coeruleopunctatus with all genetic distance averages type. 0.02. The conclusion of this study is that in general the species relationships found are several species found in the same location with similar morphology and diet.
