Upper Cretaceous Araucarian Cones from Hokkaido and Saghalien: Araucaria nipponensis Sp. Nov.
Download1994
Stockey, R.A., Nishida, M., Nishida, H.
Six ovulate, permineralized cones, four cone-scale complexes, and one isolated seed are described from the Upper Cretaceous Upper Yezo and Miho Groups from Hokkaido, Japan, and Saghalien, Russia. Cones are spherical, 3.5-6.0 cm in diameter, with prominent thick bracts. Thick ovuliferous scales...

Urticalean Rosids: Circumscription, rosid ancestry, and phylogenetics based on rbcL, trnL-F, and ndhF sequences
Download2002
Conti, E., Nepokroeff, M., Chase, M.W., Pires, J.C., Morawetz, J., Zjhra, M., Hall, J.C., Sytsma, K.J.
To address the composition of the urticalean rosids, the relationships of the component families (maximally Cannabaceae, Cecropiaceae, Celtidaceae, Moraceae, Ulmaceae, and Urticaceae) and analyze evolution of morphological characters, we analyzed sequence variation for a large sampling of these...

Use of the DCB Technique for Extraction of Hydrous Iron Oxides from Roots of Wetland Plants.
Download1983
Replicate samples of Phragmites communis roots coated with hydrous iron oxide were analyzed for internal and external Fe using the dithionite-citrate-bicarbonate technique (hot DCB), a modified DCB technique (cold DCB), Ethylenediaminete traacetic acid (EDTA), Diethylenetriamine pentaacetic acid...

Olmstead, Richard G., Graham, Sean W.
Sequences from 14 slowly evolving chloroplast genes (including three highly conserved introns) were obtained for representative basal angiosperm and seed-plant taxa, using novel primers described here. These data were combined with published sequences from atpB, rbcL, and newly obtained sequences...

Variation in Performance on cry1Ab-Transformed and Nontransgenic Rice Varieties Among Populations of Scirpophaga incertulas (Lepidoptera: Pyralidae) from Luzon Island, Philippines
Download2000
Gould, F., Bentur, J. S., Cohen, M. B.
Abstract: We quantified variation in performance under greenhouse conditions among seven populations of Scirpophaga incertulas (Walker) from Luzon Island, Philippines, on three rice varieties: 'IR58' transformed with the cry1Ab gene from Bacillus thuringiensis Berliner, and nontransgenic IR58 and...

Variation in premaxillary tooth count and a developmental abnormality in a tyrannosaurid dinosaur
Download2010
Tanke, D. H., Currie, P. J., Miyashita, T.
Premaxillary tooth count tends to be stable amongst toothed dinosaurs, and most theropods have four teeth in each premaxilla. Only one case of bilaterally asymmetric variation is known in theropod premaxillary dentition, and there is no record of ontogenetic or individual variation in...

Vegetative Growth of Decodon allenbyensis (Lythraceae) from the Middle Eocene Princeton Chert with Anatomical Comparisons to Decodon verticillatus.
Download2003
Large numbers of roots and stems of aquatic Lythraceae have been found in association with fruits and seeds of Decodon allenbyensis Cevallos-Ferriz et Stockey in the Princeton chert, British Columbia, Canada. The permineralized fossils come from layer 43 in the chert, part of the Middle Eocene,...

Vegetative Growth of Eorhiza arnoldii Robison and Person from the Middle Eocene Princeton Chert Locality of British Columbia.
Download1994
Anatomical studies of several thousand specimens of Eorhiza arnoldii Robison and Person rhizomes and their attached organs have added significantly to our knowledge of these Middle Eocene, semiaquatic dicotyledonous plants from the Princeton chert. Anatomical structure of Eorhiza was studied...
