Abstract: A cluster of genes of the CYP6 family was found in a series of overlapping lambda DASH clones from a genomic library of the house fly, Musca domestica, Four complete genes, CYP6A3, CYP6A4, CYP6A5, and CYP6C1, and fragments of two other genes, CYP6A6 and CYP6C2, were closely linked on a...

A new species of extinct conifer plants, Emporia royalii sp. nov. Hernandez-Castillo, Stockey, Mapes et Rothwell (Emporiaceae: Voltziales), is described from the rich fossil biota of the Late Pennsylvanian, Hamilton Quarry, Kansas. This conifer has lateral plagiotropic branches with simple and...
Abdominal contents from two large Early Cretaceous compsognathids (Dinosauria: Theropoda) demonstrate feeding on confuciusornithids and dromaeosauridsDownload
Two skeletons of the large compsognathid Sinocalliopteryx gigas include intact abdominal contents. Both specimens come from the Jianshangou Beds of the lower Yixian Formation (Neocomian), Liaoning, China. The holotype of S. gigas preserves a partial dromaeosaurid leg in the abdominal cavity, here...
A repetitive element of approximately 200 bp was cloned from harbour seal (Phoca vitulina concolour) genomic DNA. The sequence of the element revealed putative RNA polymerase III control boxes, a poly A tail and direct terminal repeats characteristic of SINEs. Sequence and secondary structural...
Different scales of spatial segregation of two species of feather mites on the wings of a passerine birdDownload
The \"condition-specific competition hypothesis\" proposes that coexistence of 2 species is possible when spatial or temporal variations in environmental conditions exist and each species responds differently to those conditions. The distribution of different species of feather mites on their...
Freshwater Sponges Have Functional, Sealing Epithelia with High Transepithelial Resistance and Negative Transepithelial PotentialDownload
Epithelial tissue — the sealed and polarized layer of cells that regulates transport of ions and solutes between the environment and the internal milieu — is a defining characteristic of the Eumetazoa. Sponges, the most ancient metazoan phylum , , are generally believed to lack true...
