Genetic divergence of mitochondrial DNA does not necessarily correspond to reproductive isolation. However, if mitochondrial DNA lineages occupy separate segments of environmental space, this supports the notion of their evolutionary independence. We explore niche differentiation among three candidate species of crested newt (characterized by distinct mitochondrial DNA lineages) and interpret t...

An integrated memory cell with a mem-ristor and a trilayer crested barrier selector, showing repeatable nonlinear current-voltage switching loops is presented. The fully atomic-layer-deposited TaN1+x /Ta2 O5 /TaN1+x crested barrier selector yields a large nonlinearity (>10(4) ), high endurance (>10(8) ), low variability, and low temperature dependence.

RNA sequencing and short-read assembly was utilized to produce a transcriptome of ovarian tissues from three-year-old diploid and tetraploid loaches (Misgurnus anguillicaudatus). A total of 28,369 unigenes were obtained, comprising 10,546 unigenes with length longer than 1000 bp. More than 73% of the unigenes were annotated through sequence comparison with databases. The RNA-seq data revealed t...

A transient increase in the level of free cytosolic Ca2+ is observed upon fertilization of the eggs of many species and is thought to represent a key event in the initiation of development. To identify components in the egg which could be involved in mediating such Ca2+ signals we searched for Ca(2+)-binding proteins in eggs of the fresh-water fish Misgurnus fossilis (loach). We show that loach...

Crested wheatgrass being high drought-resistant, is a promising forage crop for the Republic of Bashkortostan. It relevant in developing varieties adapted to environmental stress factors that have productive longevity, increased seed and fodder productivity. The paper presents research results crested conducted nursery competitive variety testing productivity 2018-2020. High due well-developed ...

Natural occurrence of hexaploid loach Misgurnus anguillicaudatus detected in central China is reported here for the first time. The evidences from karyotyping, DNA content analysis and nuclear volume measurements were described to confirm the hexaploid nature of the identified individual.

the rectangular broad crested weirs are widely used to measure the water dischargewhich is one of the most popular tools in the irrigation canals particularly, in developingcountries.the present article is trying to demonstrate the results of an experimental work carriedout on rectangular broad crested weir with sloped upstream face to investigate the effect ofupstream slope on discharge effici...

The Crested Ibis Nipponia nippon was once thought to be extinct in the wild until seven birds were discovered in a remote mountain village in China in 1981. Studies suggested that winter-flooded rice fields play an essential role in nest site selection by the Crested Ibis and hence in their survival. Considerable efforts were therefore made to conserve the winter-flooded rice fields, but these ...

In this study, we measured the morphometric and histological changes in the cyprinid loach, Misgurnus anguillicaudatus, during the early period of growth. Eyes, yolk length, yolk height, and yolk volume of the larva decreased for 16 days post hatching (DPH) (P<0.05). During 60 DPH (P>0.05), the most anterior extension of the head × the posterior end of the supraoccipital, the most anterior exte...

Length weight relationships (LWRs) are presented for six loach species belonging to two families of Gastromyzontidae and Nemacheilidae captured in the Baleh River Basin, Sarawak, Malaysia. One time sampling was conducted at each station representing first- fourth-order tributaries Basin from April 2014 November 2015. Loach samples were collected via electrofishing method measured total length n...
