Molecular phylogenetic analyses of genus Crocodylus (Eusuchia, Crocodylia, Crocodylidae) and the taxonomic position of Crocodylus porosus

Crocodylian diversity peak and extinction in the late Cenozoic of the northern Neotropics

“…C. acutus and C. intermedius share an anterior process of palatines wider than the posterior process (32-2). Although only one feature groups them together, the sister-group relationship between C. acutus and C. intermedius has been already proposed by molecular phylogenies 7,[19][20][21] . The New World clade is a wellsupported group and has accumulated distinctive differences from its sister taxon, C. niloticus, and other extant and extinct crocodile species (Fig.…”

Population genetics implications for the conservation of the Philippine Crocodile Crocodylus mindorensis Schmidt, 1935 (Crocodylia: Crocodylidae)

“…Molecular genetic methodology has been used to address taxonomic issues, assess genetic variability and inbreeding, track gene flow and detect hybridization, all in an effort to conserve genetically healthy populations and aid in the identification of ecologically significant units (Fleischer 1998). The use of nuclear DNA (nucDNA) and mitochondrial DNA (mtDNA) sequence data in crocodilian research has increased our understanding of genetic variability (Flint et al 2000;Ray et al 2004;Russello et al 2007), hybridization (FitzSimmons et al 2002;Ray et al 2004;Cedeño-Vásquez et al 2008), differences between individuals (Farias et al 2004), populations (Vasconcelos et al , 2008 and species (Li et al 2007;Gatesy & Amato 2008;Meganathan & Dubey 2009;Meganathan et al 2010). Microsatellites have been used to investigate population structure and gene flow in wild populations of Morelet's Crocodile Crocodylus moreletii Duméril & Bibron, 1851 (Dever & Densmore 2001;Dever et al 2002), American Alligator Alligator mississippiensis Daudin, 1802 (Glenn et al 1998;Davis et al 2002) and Black Caiman Melanosuchus niger Spix, 1825.…”

DEVELOPMENT OF SPECIFIC PRIMERS FOR INTER SPECIES PHYLOGENY RELATIONSHIP ON Crocodilian sp

“…Bioinformatics cannot be ignored, it consists million of genetic sequences information database and various valuable analyzing tools (Mount, 2004). We observed mtDNA are popular and widely used in Crocodylian phylogenetic studies, together with their sequences information deposited in GenBank (see McAliley et al, 2006;Li et al, 2007;Meganathan et al, 2010;Meganathan et al, 2011;Meredith et al, 2011).…”

“…Primer-BLAST (Basic Local Alignment Search Tool) software was used to design primers, followed by arrangement to discover the genus specific primers. Meganathan et al (2010). They use bayesian analyses, which used Ornithine-decarboxylase and C-mos, also ND4 and ND6 respectively.…”
