Creating a legal framework for copyright management of open access within the Australian academic and research sector

This chapter analyses the copyright law framework needed to ensure open access to outputs of the Australian academic and research sector such as journal articles and theses. It overviews the new knowledge landscape, the principles of copyright law, the concept of open access to knowledge, the recently developed open content models of copyright licensing and the challenges faced in providing greater access to knowledge and research outputs.

The complete mitochondrial DNA sequence and the phylogenetic position of Achalinus meiguensis (Reptilia: Squamata)

The mitochondrial genome complete sequence of Achalinus meiguensis was reported for the first time in the present study. The complete mitochondrial genome of A. meiguensis is 17239 bp in length and contains 13 protein-coding genes, 22 tRNA, 2 rRNA, and 2 non-coding regions (Control regions). On the basis of comparison with the other complete mitochondrial sequences reported, we explored the characteristic of structure and evolution. For example, duplication control regions independently occurred in the evolutionary history of reptiles; the pseudo-tRNA of snakes occurred in the Caenophidia; snake is shorter than other vertebrates in the length of tRNA because of the truncations of T psi C arm (less than 5 bp) and "DHU" arm. The phylogenic analysis by MP and BI analysis showed that the phylogenetic position of A. meiguensis was placed in Caenophidia as a sister group to other advanced snakes with the exclusion of Acrochordus granulatus which was rooted in the Caenophidia. Therefore we suggested that the subfamily Xenodermatinae, which contains A. meiguensis, should be raised to a family rank or higher rank. At the same time, based on the phylogenic statistic test, the tree of Bayesian was used for estimating the divergence time. The results showed that the divergence time between Henophidia and Caenophidia was 109.50 Mya; 106.18 Mya for divergence between Acrochordus granulatus and the other snakes of the Caenophidia; the divergence time of A. meiguensis was 103 Mya, and Viperidae diverged from the unilateral of Elapidae and Colubridae was 96.06 Mya.

Molecular phylogeography of endangered sharp-snouted pitviper (Deinagkistrodon acutus; Reptilia, Viperidae) in Mainland China

Using phylogenetic and population genetic approaches, the present study reports the phylogeographic structure of the sharp-snouted pitviper (Deinagkistrodon acutus), a threatened snake species with commercial and medicinal importance in China. The entire mitochondrial ND2 gene (NADH dehydrogenase subunit 2) sequences of 86 individuals of D. acutus from 14 localities across its range in China were determined. Based on the results of phylogenetic analyses, distribution of diagnostic sites, haplotype network, and AMOVA hierarchical analysis, an cast-west division of the whole D. acutus population could be observed. Geographically, a line formed by a lake, river, and mountain chain (the Poyang Lake, Gan River to the southern end of the Wuyi Mountains), results in vicariance and approximately vertically splits the range into two and the whole population into two main lineages (western and eastern). The bifurcating tree suggested generally west to east dispersal trend. The data fit the isolation by distance (IBD) model well. Star-like clusters in haplotype network, significantly negative values of Fs statistics, and unimodal mismatch distributions all suggest recent demographic expansions in four areas. The results show that isolation, dispersal, bottleneck, and expansion jointly constitute the history of D. acutus. In a haplotype network, the excessive predominance of central haplotypes, few medium-frequency haplotypes, predominance (73.1 %) of the singletons among the derived haplotypes, most of which are connected to the central haplotype by only one mutational step, unsymmetrical campanulate unimodal curve of mismatch distributions and leftwards shift of the peaks, all suggest that the whole D. acutus population is a young population with low genetic diversity. Based on the data, the first priority for conservation action should be given to the Huangshan unit. (c) 2007 Elsevier Inc. All rights reserved.
