Time Of Origin

Numerical cladistic analysis of 73 cranial and postcranial characters has resulted in a highly corroborated hypothesis describing the phylogenetic pattern of early avian evolution. Using “non-avian theropod” dinosaurs as a comparative outgroup and root for the tree, the analysis confirmed Archaeopteryx to be the sister-group of all remaining avian taxa, or Ornithurae. This latter taxon is subdivided into two lineages, the Hesperornithiformes and the Carinatae. The carinates, in turn, were also resolved into two sister-groups, the Ichthyornithiformes and the modern birds, or Neornithes. This paper provides morphological data corroborating the divergence of the two basal clades of the Neornithes: the Palaeognathae (tinamous and ratites) and Neognathae (all other modern birds). The phylogenetic relationships of four important Cretaceous taxa were also investigated, but these fossil taxa were too fragmentary to determine their phylogenetic position unambiguously. Alexornis and Ambiortus are both carinates, but their relationships cannot be resolved in greater detail. The relationships of the Enantiornithes may lie within the Carinatae or these two taxa may be sister-groups. Gobipteryx is a neornithine and possibly the sister-group of the Palaeognathae.This analysis indicates that major patterns of morphological change took place at the time of origin of the ancestors of the Ornithurae and the Carinatae. Ornithurine innovations included major changes throughout the skeleton, whereas those of the carinates, while substantial, were primarily restricted to the pectoral girdle and forelimb. The phylogenetic results, in conjunction with the known ages of fossil taxa, indicate that the early lineages of birds very likely arose in the Jurassic. The early cladistic events within the neornithine lineage are also more ancient than generally recognized, and may well extend back to the early Cretaceous.

Dissimilarity Matrix

A dissimilarity matrix of genera of Triticeae, computed from the amalgamation of morphological data and genetic relationships in terms of successful crosses between the genera, has been subjected to Farris's distance Wagner procedure. One of the almost identical two Wagner networks obtained was superimposed on an ordination plot of the genera in two-dimensional space. This enabled representation of the multidimensionality of the phylogenetic relationships among the genera of this tribe. The findings and interpretation are discussed and compared with results on intergeneric relationships obtained by various cytogeneticists.

Close Relationship

The tribe Junoniini is a predominantly Paleotropical group of the cosmopolitan butterfly subfamily Nymphalinae (Nymphalidae), with highest diversity in the Afrotropical region. Its systematics and relationships are not entirely resolved. Question marks remain concerning the validity of some genera; and the apparently close relationship between the Indo-Australian genus Yoma and the Afrotropical Protogoniomorpha, as evidenced by molecular phylogenies, remains a puzzle. Here, we present a cladistic analysis, based on 42 characters of the male and female genitalia of 41 species of Junoniini belonging to six genera, nearly all of them continental Afrotropical, and 3 species of two Indo-Australian genera Yoma and Rhinopalpa. A ML COI-based tree is produced for 36 species of Afrotropical Junoniini and Yoma. The molecular data are consistent with previous studies. However, morphological analysis does not confirm a close relationship between Protogoniomorpha and Yoma. Despite the evolution of a number of modifications, the male genitalia within all genera and species of the Junoniini share a cohesive build plan, in particular a transformed sacculus, from which Yoma is highly divergent. The position of the genus Kamilla, previously synonymized with Junonia, is discussed. Three East African coast taxa, Junonia elgiva stat. reinst., Protogoniomorpha nebulosa stat. reinst. and Salamis amaniensis stat. reinst., and one from central Africa, Precis silvicola stat. reinst. are raised to species level, based on comparative analysis of their male genitalia.

Trunk Limb

The phylogenetic relationships among families of the Order Anomopoda (Crustacea, Branchiopoda, Cladocera) were investigated through a cladistic analysis including 93 characters and 37 terminal taxa (2 as outgroups). The strict consensus tree supported the monophyly of the Anomopoda and its families, and indicated the existence of two main clades: (Moinidae+Daphniidae) and (Dumontidae (Ilyocryptidae+Bosminidae+Radopoda)). The later clade was supported by trunk limb characters, probably related to life associated with the bottom or with macrophytes (lifestyle lost in Bosminidae, but still visible in some of its trunk limbs). Within the Radopoda, the Eurycercoidea was monophyletic, but the monophyly of the Macrothricoidea was not supported.

Cladistic Analysis

The Holarctic genus Piezura Rondani (Diptera, Fanniidae) is reviewed. Phylogenetic relationships among the species in this group, as well as the biogeography of these species, are discussed on the basis of a cladistic analysis. Piezura graminicola shanxiensis Xue, Wang and Wu, 1998 is redescribed and elevated to species rank based on comparison of its morphology and phylogenetic relationships. Syllegopterula flava Hsue, 1983 and its replacement name Thricops flavidus Xue, 1998 are treated as junior synonyms of Piezura graminicola (Zetterstedt, 1846).

A New Species

The genus Minuartia is represented in Turkey by 34 taxa. Some interesting specimens were collected from Antalya province, and examined. These specimens resemble Minuartia meyeri, and M. multinervis from which differ by characters (macro-, and micromorphological) of inflorescence, alar pedicels, petals, sepals, capsules and seeds. Moreover, by using the DNA sequences of the ITS genes, phylogenetic relationships between this collected species, and the related species were investigated. As a result of the evaluation of molecular, and morphological data, we proposed to described the population from Antalya as a new species for the science. A description, pictures, distribution, habitat, and IUCN category are given.
