The Anatomical Record, EarlyView.Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

Animal Research and One Health, EarlyView.Conserving genetic material and even increasing genetic diversity is critical. To conduct the conservation of wild boar germplasm resources, we have successfully obtained healthy cloned wild boars for the first time using interspecies somatic cell nuclear transfer and established transgene‐free iPSCs that can be used to conduct iterative rounds of gene

Ecology Letters, 2008 Ecologists are increasingly adopting an evolutionary perspective, and in recent years, the idea that closely related species are ecologically similar has become widespread. In this regard, phylogenetic signal must be distinguished from phylogenetic niche

Ancient Phylogenetic Relationships
Theoretical Population Biology, 2002Traditional views on deep evolutionary events have been seriously challenged over the last few years, following the identification of major pitfalls affecting molecular phylogeny reconstruction. Here we describe the principally encountered artifacts, notably long branch attraction, and their causes (i.e., difference in evolutionary rates, mutational ...

Taxonomy and phylogenetic relationship of zokors
Journal of Genetics, 2020Zokor (Myospalacinae) is one of the subterranean rodents, endemic to east Asia. Due to the convergent and parallel evolution induced by its special lifestyles, the controversies in morphological classification of zokor appeared at the level of family and genus.

Phylogenetic relationships of cyphelloid homobasidiomycetes
Molecular Phylogenetics and Evolution, 2004The homobasidiomycetes includes the mushroom-forming fungi. Members of the homobasidiomycetes produce the largest, most complex fruiting bodies in the fungi, such as gilled mushrooms ("agarics"), boletes, polypores, and puffballs. The homobasidiomycetes also includes species that produce minute, cup- or tube-shaped "cyphelloid" fruiting bodies, that ...

Phylogenetic relationships within Colchicaceae
American Journal of Botany, 2003Three plastid regions—the rps16 intron, the atpB‐rbcL intergenic spacer, and the trnL‐F region—in 73 taxa representing all the genera of Colchicaceae except Kuntheria were sequenced to investigate the intrafamilial relationships of the family. In total, the three gene regions, comprising 3830 characters, were analyzed both separately and in a combined ...

Phylogenetic relationships of the Santalales and relatives
Journal of Molecular Evolution, 1990Determining relationships among parasitic angiosperms has often been difficult owing to frequent morphological reductions in floral and vegetative features. We report 18S (small-subunit) rRNA sequences for representative genera of three families within the Santalales (Olacaceae, Santalaceae, and Viscaceae) and six outgroup dicot families (Celastraceae,
