POYARKOV, JR., NIKOLAY A.,CHE, JING,MIN, MI-SOOK,KURO-O, MASAKI,YAN, FANG,LI, CHENG,IIZUKA, KOJI,VIEITES, DAVID R. Magnolia Press 2012 Zootaxa Vol.3465 No.1
<P>We describe four new species of Asian Clawed salamanders of the genus Onychodactylus (Caudata: Hynobiidae), basedon fresh material collected during fieldwork in Japan, Korea, the Russian Far East and northeastern China between 2003and 2010, as well as older voucher specimens deposited in several museums. Our analyses comprise all species currentlyrecognized within this genus across its entire distribution range. We follow an integrative taxonomic approach bycombining detailed morphological comparative analyses with molecular phylogenetic analyses. We find significantdifferences among species in this genus, based on morphological and molecular data, which resulted in the recognitionand description of four new species within this genus. The new species have uncorrected molecular divergences of over4.5-7.4% and 1.9-4.1% to their closest relatives in the mitochondrial COI and 16S rRNA genes respectively. In themolecular analyses, we found two very divergent lineages in Korea and Japan that need further investigation, as detailedmorphological data are not available for them. We also discuss our approach to delimit species on salamanders. For thenew species described in this group we evaluate their threat status according to IUCN criteria: O. koreanus sp. nov. Min,Poyarkov & Vieites and O. nipponoborealis sp. nov. Kuro-o, Poyarkov & Vieites are classified as Least Concern, whileO. zhaoermii sp. nov. Che, Poyarkov & Yan and O. zhangyapingi sp. nov. Che, Poyarkov, Li & Yan are classified as Vulnerable (Vu2a).</P>

Discovery of the first Asian plethodontid salamander
Min, M. S.,Yang, S. Y.,Bonett, R. M.,Vieites, D. R.,Brandon, R. A.,Wake, D. B. Nature Publishing Group 2005 Nature Vol.435 No.7038
Nearly 70% of the 535 species of salamanders in the world are members of a single family, the Plethodontidae, or lungless salamanders. The centre of diversity for this clade is North and Middle America, where the vast majority (99%) of species are found. We report the discovery of the first Asian plethodontid salamander, from montane woodlands in southwestern Korea. The new species superficially resembles members of North American genera, in particular the morphologically conservative genus Plethodon. However, phylogenetic analysis of the nuclear encoded gene Rag-1 shows the new taxon to be widely divergent from Plethodon. The new salamander differs osteologically from putative relatives, especially with respect to the tongue (attached protrusible) and the derived tarsus. We place the species in a new genus on the basis of the morphological and molecular data. The distribution of the new salamander adds to the enigma of Old World plethodontids, which are otherwise restricted to the western Mediterranean region, suggesting a more extensive past distribution of the family.

Worldwide prevalence of noncommunicable chronic degenerative diseases is among the main causes of death worldwide. The consumption of some foods such as nuts and seeds may be beneficial in preventing these diseases. Dipteryx alata Vogel (DA), known popularly as Baru, belongs to the family Fabaceae and is a native fruit tree from the Brazilian savanna. The purpose of this study was to evaluate the use of seeds of DA on the metabolic and oxidative profile of Wistar rats. Animals were divided randomly into four groups (n = 10): G1 (control group), and G2 (treated with DA 20%), G3 (treated with DA 30%), and G4 (treated with DA 40%). After 40 days, animals were euthanized and metabolic and oxidative profiles were analyzed (glycemia, cholesterol, triglycerides [TGs], high-density lipoprotein-cholesterol [HDL-c], very low-density lipoprotein-cholesterol [VLDL-c], low-density lipoprotein-cholesterol [LDL-c], C reactive protein, aspartate aminotransferase, alanine aminotransferase, Lee index, weight, visceral fat, ferric reducing ability of plasma, and ferric–xylenol orange method. The use of the seeds was effective in reducing TGs, VLDL-c, LDL-c, and increasing HDL-c but did not interfere in the percentage of weight gain, visceral fat, levels of total cholesterol, and oxidative stress. Based on our results, it is possible to say that the use of DA may improve the lipid profile of Wistar rats and we may suggest that the consumption of DA almonds or products prepared with them may be an effective option for the intake of healthy products.
