Cytogenetic analysis of Liza ramada (Pisces, Perciformes) by different staining techiques and fluorescent in situ hybridization
No full textGenetic divergence and phylogenetic inferences in five species of Mugilidae (Pisces : Perciformes)
No full textAllozyme electrophoresis was used to compare the genetic divergence of global populations of Mugil cephalus Linnaeus, 1758 and two congeneric [M. curema Cuvier & Valenciennes, 1836; M. gyrans (Jordan & Gilbert, 1855)] and two more distantly related [Liza ramada (Risso, 1826); Xenomugil thoburni (Jordan & Starks, 1896)] species on the basis of LS enzyme loci. The amount of genetic divergence among the species examined is in agreement with their present systematic status, the differences being larger among non-congeneric species than among species of the same genus. Intraspecific genetic distances in M. cephalus (average Nei's D = 0.154), although higher than those reported for conspecific populations of fish, appear to be small when compared to the interspecific values among mugilid species (0.821 less than or equal to Nei's D less than or equal to 1.744). Phylogenetic trees obtained by genetic distance methods and discrete character parsimony analysis were of similar topology, except for the relationships within the genus Mugil and for the arrangement of M. cephalus populations

No full textMeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Genetics of Mugilidae
No full textMullets (grey mullets) are a family (Mugilidae) and order of ray-finned fish found in temperate and tropical waters worldwide. There are approximately 80 species of mullet; these fish have been considered an important food source in Mediterranean Europe since Roman times. This book provides a long overdue update on the biology and ecology of mullets and features comprehensive coverage of the key features of the Mugilidae family, such as recent DNA evidence and morphological data that challenge the traditional taxonomy
