A morphologically based cladistic analysis of 40 genera included within the Trichostrongyloidea (Amidostomatidae, Dromaeostrongylidae and Trichostrongylidae) is proposed. Two genera were used as outgroups, one from the Strongylina and the other from the Ancylostomatina. Seven genera do not appear in the matrix because some significant morphological characters remain unknown for these genera. No...

Advocates of cladistic parsimony methods have invoked the philosophy of Karl Popper in an attempt to argue for the superiority of those methods over phylogenetic methods based on Ronald Fisher's statistical principle of likelihood. We argue that the concept of likelihood in general, and its application to problems of phylogenetic inference in particular, are highly compatible with Popper's phil...

A two-stage cladistic analysis of 114 characters from adult and immature stage morphology provided phylogenetic hypotheses for the diverse Neotropical nymphalid butterfly genus Adelpha Hübner. Higher-level cladistic relationships were inferred for thirty Adelpha species and twenty other species of Limenitidini, confirming the monophyly of Adelpha as currently conceived and indicating several mo...

INTRODUCTION With the increase in genotype data generated by high throughput typing technologies, there is currently a lack of complexity-oriented analytical methods that can maximise the information obtained from these raw data for the study of complex diseases. We introduce the cladistic analysis that is traditionally applied in evolution studies and taxonomy, to specify relevant comparisons ...

Diadromy, broadly defined here as the regular movement between freshwater and marine habitats at some time during their lives, characterizes numerous fish and invertebrate taxa. Explanations for the evolution of diadromy have focused on ecological requirements of individual taxa, rarely reflecting a comparative, phylogenetic component. When incorporated into phylogenetic studies, center of orig...

Eleven new replacement names in the genus Mesochorus Gravenhorst, 1829 are proposed due the synonymy with Plectochorus Uchida, 1933 and Stictopisthus Thomson, 1886 made by Wahl in his cladistic analysis of the genera of Mesochorinae.

The five instars of Teleonemia scrupulosa Stål are described. The postembryonic ontogenetic development of integumentary structures is emphasized, with a discussion on its potential use in cladistic studies within Tingidae.
