Sperling, F. A. H., Spence, J. R.

Five species of Limnoporus Stål (L. canaliculatus [Say], L. dissortis [Drake and Harris], L. nearcticus [Kelton], L. notabilis [Drake and Hottes], and L. rufoscutellatus [Latreille]) were each sampled at 20 electrophoretic loci. Twofold differences among species in mean heterozygosity appear to...

Keyghobadi, N., Roland, J., Fownes, S.

We used mark-recapture methods to estimate the number of Parnssius smintheus (Papilionidae) butterflies moving among 20 alpine meadows separated by varying amounts of forest along the east slope of the Rocky Mountains in Alberta, Canada. We combined generalized additive models and generalized...

Glamm, A. B., Swanson, C. A., Borchers-Zampini, C., Hoddinott, J.

Bean plants, trimmed to a simplified “double source, double sink” translocation system (the paired primary leaves serving as the double source and the paired lateral leaflets of the immature first trifoliate leaf as the double sink) were used to study the magnitude and short-term time course of...

Bell, J. B., Deng, H., Simmonds, A. J., Hughes, S. C.

Abstract: Vertebrate development requires the activity of the myocyte enhancer factor 2 (mef2) gene family for muscle cell specification and subsequent differentiation. Additionally, several muscle-specific functions of MEF2 family proteins require binding additional cofactors including members...

Kimura, K., Southron-Francis, J. L., Iuchi, S., Furuzawa, A., Taylor, G. J., Kobayashi, Y., Koyama, H., Kobayashi, M., Kuroda, K.

Copper (Cu) is an essential element in plant nutrition, but it inhibits the growth of roots at low concentrations. Accessions of Arabidopsis ( Arabidopsis thaliana) vary in their tolerance to Cu. To understand the molecular mechanism of Cu tolerance in Arabidopsis, we performed quantitative trait...

Gifford, D. J., King, J. E.

Abstract: The mobilization and utilization of the major storage proteins in loblolly pine (Pinus taeda L.) seeds following imbibition were investigated. Most of the seed protein reserves were contained within the megagametophyte. Breakdown of these proteins occurred primarily following radicle...

Hickey, D. A., Sperling, F. A. H.

Abstract: We describe a method for identifying conifer-feeding species and lineages of Choristoneura Lederer in Canada and Alaska. The method relies on amplification of mitochondrial (mt) DNA by the polymerase chain reaction (PCR); amplified DNA is then digested with restriction enzymes to give...

Foght, J.M., Adebusuyi, A.A.

Background Efflux pumps belonging to the resistance-nodulation-division (RND) superfamily in bacteria are involved in antibiotic resistance and solvent tolerance but have an unknown physiological role. EmhABC, a RND-type efflux pump in Pseudomonas fluorescens strain cLP6a, extrudes hydrophobic...

Lech-Hernes, N. L., Currie, P. J., Arbour, V. M., Hurum, J. H., Guldberg, T. E.

A Mongolian ankylosaurid specimen identified as Tarchia gigantea is an articulated skeleton including dorsal ribs, the sacrum, a nearly complete caudal series, and in situ osteoderms. The tail is the longest complete tail of any known ankylosaurid. Remarkably, the specimen is also the first...

LePage, B.A., Currah, R.S., Stockey, R.A.

Two ascomycetes from the middle Eocene (48.7 million yr b.p.) Princeton chert are described. Palaeoserenomyces allenbyensis gen. et sp. nov. consists of long, loculate stromata of distinctive columnar cells beneath the epidermis of the extinct fan palm, Uhlia allenbyensis. The sporogenous locules...
