Population genetic structure of critically endangered salamander (Hynobius amjiensis) in China: recommendations for conservation
Authors: J. Yang, C.S. Chen, S.H. Chen, P. Ding, Z.Y. Fan, Y.W. Lu, L.P. Yu and H.D. Lin
Amji’s salamander (Hynobius amjiensis) is a critically endangered species (IUCN Red List), which is endemic to mainland China. In the present study, five haplotypes were genotyped for the mtDNA cyt b gene in 45 specimens from three populations. Relatively low levels of haplotype diversity (h = 0.524) and nucleotide diver..

Genetic diversity and structure of native and non-native populations of the endangered plant Pinus dabeshanensis
Authors: Z.Y. Zhang, H. Wang, W. Chen, X.M. Pang and Y.Y. Li
Owing to a severe decline in its abundance, Pinus dabeshanensis has been listed as an endangered species by the International Union for the Conservation of Nature. Although several restoration events have been undertaken since the 1960s, the natural population genetic structure of this species remains to be investigated. Herei.. Read More»

Genetic diversity and structure of the threatened species Sinopodophyllum hexandrum (Royle) Ying
Authors: W. Liu, J. Wang, D.X. Yin, M. Yang, P. Wang, Q.S. Han, Q.Q. Ma, J.J. Liu and J.X. Wang
Sinopodophyllum hexandrum is an important medicinal plant that has been listed as an endangered species, making the conservation of its genetic diversity a priority. Therefore, the genetic diversity and population structure of S. hexandrum was investigated through inter-simple sequence repeat analysis of eight natural populati.. Read More»

Genetic diversity of Vriesea cacuminis (Bromeliaceae): an endangered and endemic Brazilian species
Authors: P.C.C. Ribeiro, L.C. Pinheiro, R. Domingues, R.C. Forzza, M.A. Machado and L.F. Viccini
Data about the genetic structure can help to understand the evolutionary process of natural populations as well as to drive strategies of conservation. Vriesea cacuminis, an endemic Brazilian Bromeliad, has been found in 2 areas of Minas Gerais State. One is a legal preservation unit (Ibitipoca State Park) and the other an unprotected area (Serra Negra). .. Read More»

Effective sample selection for classification of pre-miRNAs
Authors: K. Han
To solve the class imbalance problem in the classification of pre-miRNAs with the ab initio method, we developed a novel sample selection method according to the characteristics of pre-miRNAs. Real/pseudo pre-miRNAs are clustered based on their stem similarity and their distribution in high dimensional sample space, respective.. Read More»

Genetic diversity and structure in natural populations of Maytenus truncata Reiss, 1861, a medicinal plant vulnerable to extractivism in Bahia State, Brazil
Authors: R.R. Simplicio, A.M. Waldschmidt, M.B. Amorim, B.S. Almeida and D.G. Pereira
Maytenus truncata (Celastraceae) is a plant species widely used in the treatment of ulcers and tumors. Despite the intensive harvest of native specimens in the State of Bahia, northeastern Brazil, there is no information about the genetic variability or structure of this species. Therefore, the goal of this study was to estimate the genetic diversity and .. Read More»

Identification of conservation units of the hynobiid salamander Pachyhynobius shangchengensis
Authors: L.-N. Su, Y.-Y. Zhao, X.-M. Wu, H.-F. Zhang and X.-C. Li
The evolutionary significant units (ESUs) of the salamander Pachyhynobius shangchengensis (Hynobiidae) in the Dabieshan mountains, southeastern China, were identified based on mitochondrial DNA data. We used methods for detecting cryptic species, such as the minimum spanning tree, the automatic barcode gap discovery, and the generalized mixed Yule-coalesc.. Read More»

Evolutionary analysis of the ubiquitin gene of baculovirus and insect hosts
Authors: S.S. Ma, Z. Zhang, H.C. Xia, L. Chen, Y.H. Yang, Q. Yao and K.P. Chen
Baculovirus is the only virus that has been found to encode the ubiquitin protein. In this study, ubiquitin sequences from 16 insects and 49 viruses were collected and compared. The resulting sequences were aligned with virus genomes. Then MAGE 5.0, k-estimated software, as well as other software programs were used for systemic evolutionary, selection pre.. Read More»

Non-Darwinian and Darwinian prokaryotic and eukaryotic evolution - an enigma in cell biology conservation
Authors: Hugo Hoenigsberg
Our theory is embarrassingly simple. What made today’s prokaryotes and modern cyanobacteria so robust is the fact that in their origin, back in the Archean (3 billion years ago), selection did not play a central role in evolution, it had only a transitory role. Asexual reproduction, mutation, drift and sampling variance .. Read More»
