Molecular phylogenetic evaluation of classification and scenarios of character evolution in calcareous sponges (Porifera, Class Calcarea). [PDF]

open access: yes, 2012
Calcareous sponges (Phylum Porifera, Class Calcarea) are known to be taxonomically difficult. Previous molecular studies have revealed many discrepancies between classically recognized taxa and the observed relationships at the order, family and genus ...

Resolution among major placental mammal interordinal relationships with genome data imply that speciation influenced their earliest radiations [PDF]

open access: yes, 2010
Background: A number of the deeper divergences in the placental mammal tree are still inconclusively resolved despite extensive phylogenomic analyses.

A new species of Circinaria (Pertusariales, Megasporaceae) from Pakistan [PDF]

open access: yesBotanica Serbica, 2023
Circinaria pakistanica sp. nov. is described from the Himalayan moist temperate forests in Pakistan. The morphology, chemistry and ITS sequence support its distinction from other species of this genus. The taxon is characterised by a whitish to blackish

Worldwide Phylogenetic Relationship of Avian Poxviruses [PDF]

open access: yesJournal of Virology, 2013
ABSTRACTPoxvirus infections have been found in 230 species of wild and domestic birds worldwide in both terrestrial and marine environments. This ubiquity raises the question of how infection has been transmitted and globally dispersed. We present a comprehensive global phylogeny of 111 novel poxvirus isolates in addition to all available sequences ...

Phylogenetic relationships in Betula (Betulaceae) based on AFLP markers [PDF]

open access: yes, 2008
The genus Betula comprises various species in boreal and temperate climate zones of the Northern Hemisphere. The taxonomy of Betula is controversial and complicated by parallel evolution of morphological traits, polyploidization events, and extensive ...

The taxonomic position of the Ctenostylidae (= Lochmostyliinae; Diptera: Schizophora)

open access: yesMemorias do Instituto Oswaldo Cruz, 1989
It is shown that Ctenostylidae Bigot (1882) is a valid senior synonym of Lochmostylidae Hendel (1935). The morphology of the Ctenostylidae is considered and compared with the Pyrgotidae.
