![]() ![]() lenok tsinlingensis is thought to be a glacial relict, as one of the southernmost Salmonidae species (the other one is Hucho bleekeri) ( Li, 1984 Yue and Chen, 1998). Based on comparing some characters of specimens from two geographical populations (the Amur River and the streams of Qinling Mountains), such as number of gill rakers, lateral-line scales and pyloric caeca, Li (1966) considere that the Brachymystax fish distributed in the Qinling differ from that of Amur River, and described it as an endemic subspecies, and named as Brachymystax lenok tsinlingensis Li. In China, the genus Brachymystax distributes in Amur River drainage, Tumen River, Yalu River, Luanhe River, IrtySh River, Burqin River, Ulungur River and the southern and northern streams of Qinling Mountains ( Huang et al. The genus Brachymystax Günther, 1866, belonging to Salmonidae, Salmoniformes, widely distributes in the rivers of Siberia, Mongolia, the Korea Peninsula and north of China ( Li, 1966 Song and Fang, 1984 Qin and Wang, 1989 Froufe et al. lenok tsinlingensis could be considered as an independent species. Our morphological analysis supported the validity of taxonomic status of B. Furthermore, discriminant function analysis (DFA) showed that all samples (except six) were correctly reclassified. tumensis had short head, blunt snout and shortest eye diameter and narrow dorsoventral orientation. lenok had tapered and narrow head, sharp snout and medium diameter of eye B. lenok tsinlingensis had wider and elongate head, the longest eye diameter and the widest dorsoventral orientation B. The morphological variation was well defined by PCA and CVA: B. CV1 (65.77%) and CV2 (34.23%) were well explained 100% of the observed variation among three morphotypes by Canonical variate analyses (CVA). Principal component analysis (PCA) showed that the cumulative contribution rate of the first five principal components were 72.99%. Results of geometric morphometric analysis indicated significantly morphological variation in body shape among three morphotypes based on 18 landmarks. were collected from three locations (Heihe River, Amur and Ussuri River) to identify the taxonomic status in terms of morphological variation among these species or subspecies. lenok tsinlingensis) in the Qinling Mountains, while others believed no division of the subspecies. tumensis) in Amur River and a subspecies ( B. Some ichthyologists thought that there should be two species ( B. There is a debate on the validation of subspecies B. #Ithenticate stony brook how to#We understand the issues and know how to approach, analyze and work towards a comprehensive resolution.The genus Brachymystax mainly distributes in the Amur River and streams of the Qinling Mountains of northern China. Areas that we address include: issues of intent, definitions of infringements, establishing due diligence safeguards, developing appropriate sanctions and providing re-education procedures. Our consulting services include developing policies and procedures to deal with issues of academic dishonesty and plagiarism. Since 1990, Glatt Consulting Services has assisted academic institutions with Plagiarism Forensics. What one can do is to implement a proactive and visible program to deter plagiarism and encourage academic honesty." - Dr. "No one can eliminate plagiarism one hundred percent of the time. Prospective students place a high value on their perception of the integrity and reputation of the institution of their choice. Plagiarism undermines learning and the purposes of our academic institutions.Īt stake is the honor of your school, faculty and students. Academic integrity speaks to the heart of the educational process. ![]()
