TL;DR: Investigation of the seasonality of the bacterial assemblage composition in north-west Mediterranean coastal waters indicated that bacterial diversity changed gradually throughout the year, although with a clear distinction of the summer period, and denaturing gradient gel electrophoresis indicated that Alphaproteobacteria were the dominant group.

European species of Hypocrea Part I. The green-spored species
TL;DR: This work is a preliminary account of Hypocrea and their Trichoderma anamorphs in Europe, based on the ITS identification routine using fresh material, on species described earlier without molecular data and on species recently described but not collected during this project.
Journal ArticleDOI
A molecular phylogenetic analysis of the Octocorallia (Cnidaria: Anthozoa) based on mitochondrial protein-coding sequences.
TL;DR: The failure of these mitochondrial genes as well as previous 18S rDNA studies to resolve many of the deeper nodes within the tree suggest that octocorals underwent a rapid radiation and that large amounts of sequence data will be required in order to resolve the basal relationships within the clade.

TL;DR: The findings indicate that continued evolution of HPV types has led to even finer genetic discrimination linked to HPV natural history and cervical cancer risk, and larger viral genomic studies are warranted, especially to identify the genetic basis for HPV16's unique carcinogenicity.
Journal ArticleDOI
Timing and rate of speciation in Agave (Agavaceae)
TL;DR: The phylogenetic limits of Agave sensu lato are examined and the potential for both monocarpy and the evolution of a generalist pollination system, largely dependent on nectarivorous bat species, as possible driving factors in the radiation of the group are discussed.

A new look at the statistical model identification
TL;DR: In this article, a new estimate minimum information theoretical criterion estimate (MAICE) is introduced for the purpose of statistical identification, which is free from the ambiguities inherent in the application of conventional hypothesis testing procedure.
Journal ArticleDOI
A simple method for estimating evolutionary rates of base substitutions through comparative studies of nucleotide sequences.
TL;DR: Some examples were worked out using reported globin sequences to show that synonymous substitutions occur at much higher rates than amino acid-altering substitutions in evolution.

Dating of the human-ape splitting by a molecular clock of mitochondrial DNA.
TL;DR: A new statistical method for estimating divergence dates of species from DNA sequence data by a molecular clock approach is developed, and this dating may pose a problem for the widely believed hypothesis that the bipedal creatureAustralopithecus afarensis, which lived some 3.7 million years ago, was ancestral to man and evolved after the human-ape splitting.
