Monophyly or Paraphyly– The Taxonomy of Holcoglossum (Aeridinae: Orchidaceae)

Recently, there have been a lot of intense debates about the acceptance/rejection of paraphyletic groups in biological classification. On the one hand, evolutionary classification states that similarity and common descent are two criteria for biological classification and paraphyletic groups are natural units of biological classification. On the other hand, cladistic classification considers th...

The mitochondrial genome of the house centipede scutigera and the monophyly versus paraphyly of myriapods.

Recent advances in molecular phylogenetics are continuously changing our perception of the phylogenetic relationships among the main arthropod lineages: crustaceans, hexapods, chelicerates, and myriapods. Besides the intrinsic interest in unraveling the evolution of the largest animal phylum, these studies are basic to an understanding of one of the major transitions in animal evolution-i.e., t...

Structural rRNA characters support monophyly of raptorial limbs and paraphyly of limb specialization in water fleas.

The evolutionary success of arthropods has been attributed partly to the diversity of their limb morphologies. Large morphological diversity and increased specialization are observed in water flea (Cladocera) limbs, but it is unclear whether the increased limb specialization in different cladoceran orders is the result of shared ancestry or parallel evolution. We inferred a robust among-order c...

Monophyly/paraphyly/polyphyly and gene/species trees: an example from Drosophila.

It is fairly well accepted that, at least in theory, inferences concerning phylogenetic relationships based on molecular data may not always accurately reflect the historical relationship of the extant taxa from which the data have been acquired. One problem is polymorphism within species. Examples include both the lineage sorting of mitochondrial DNA (mtDNA), envisioned by Avise and colleagues...

A Refined End-to-End Discourse Parser

The CoNLL-2015 shared task focuses on shallow discourse parsing, which takes a piece of newswire text as input and returns the discourse relations in a PDTB style. In this paper, we describe our discourse parser that participated in the shared task. We use 9 components to construct the whole parser to identify discourse connectives, label arguments and classify the sense of Explicit or Non-Expl...
