Abstract— Protein variation among 37 species of carcharhiniform sharks was examined at 17 presumed loci. Evolutionary trees were inferred from these data using both cladistic character and a distance Wagner analysis. Initial cladistic character analysis resulted in more than 30 000 equally parsimonious tree arrangements. Randomization tests designed to evaluate the phylogenetic information content of the data suggest the data are highly significantly different from random in spite of the large… 

Taxonomy, systematics and biogeography of the Scaritinae (Insecta, Coleoptera, Carabidae)

An historical biogeographic reconstruction of the Scaritini was undertaken by incorporating evidence from extant distributions, fossils and the phylogenetic data, finding it likely that evolution of the basal lineages ofScaritini occurred before the fragmentation of Gondwana and that the present-day distributions of the later radiation of Scaritina are due to dispersal.

Phylogeny of the riodinid butterfly subtribe Theopeina (Lepidoptera: Riodinidae: Nymphidiini)

A comparative morphological study of all seventy‐five species in subtribe Theopeina (tribe Nymphidiini) yielded 104 characters, predominantly from wing pattern, male and female genitalia, and abdominal structures, which produced a large number of most parsimonious cladograms.

Phylogenetic trends in the abundance and distribution of pit organs of elasmobranchs

To investigate phylogenetic trends in the distribution and abundance of pit organs, 12 relevant morphological characters were added to an existing matrix of morphological data, which was re-analysed using cladistic parsimony methods and character transformations were traced onto the most parsimonious phylogenetic trees.

A DNA Sequence–Based Approach To the Identification of Shark and Ray Species and Its Implications for Global Elasmobranch Diversity and Parasitology

A comprehensive survey of DNA sequences derived from the mitochondrial NADH2 gene was conducted for elasmobranchs collected from around the world, suggesting 79 potentially new taxa that are genetically distinct from their closest relatives in other regions.

Electrophoretic analysis of Phylogenetic relationships among Australian Carcharhinid Sharks

The phylogenetic relationships of 17 species of carcharhinid sharks and four other closely related species were examined by allozyme electrophoresis and there appears to be a distinct lineage within the C Archarhinidae that may be characterized by the absence of the interdorsal ridge.

A randomization test for phylogenetic information in systematic data

-A randomization procedure is proposed to determine if sets of data used for phylogenetic analysis contain phylogenetically nonrandom information. The method compares the observed number of steps on

An Electrophoretic Analysis of Holarctic Hylid Frog Evolution

Calibration of the molecular clock for Holarctic hylid frogs suggests that Pseudacris diverged from a Hyla-like ancestor in the early Tertiary, and physiological traits associated with cold-weather breeding and the morphological trait associated with terrestrial habits appear to have been key innovations.

Estimating Phylogenetic Trees from Distance Matrices

The distance Wagner procedure is applicable to data matrices of immunological distance, such as that of Sarich (1969a), in which between-OTU comparisons are evaluated but for which no attributes of the OTUs themselves are directly observable.

Choosing Among Multiple Equally Parsimonious Cladograms

The issue of choice among multiple equally parsimonious cladograms, and three statistics considered, are addressed: the consistency index, F-ratio, D and the D measure, an application of the Shannon entropy statistic from Gatlin (1972).

The discovery and importance of multiple islands of most

The set of most-parsimonious trees for a data matrix may include several distinct classes (islands) of trees, and trees in different islands may have different implications for character evolution, and for this reason should be sought.
