Density-dependent variation in lifetime breeding success and natural and sexual selection in Soay ramsDownload
Variation in male lifetime breeding success (LBS) is central to understanding selection, yet it has rarely been measured in natural populations of large mammals. Here, we first describe variation in the opportunity for selection in cohorts of Soay rams (Ovis aries) on the archipelago of St....
Amplified mitochondrial DNA as a diagnostic marker for species of conifer-feeding Choristoneura (Lepidoptera: Tortricidae)Download
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...
Amino acid polymorphisms in strictly conserved domains of a P-type ATPase HMA5 are involved in the mechanism of copper tolerance variation in ArabidopsisDownload
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...
Mitochondrial cytochrome oxidase I and 11 genes were sequenced for two invasive alien birch (Betula L. [Betulaceae]) leaf-mining sawflies, Profenusa thomsoni (Konow, 1886) (Hymenoptera: Tenthredinidae) and Scolioneura betuleti (King, 1816) (Hymenoptera: Tenthredinidae), accidentally introduced...
Genetic variation in height, branch and needle lengths of Pinus sylvestris L. from Siberia tested in Alberta, CanadaDownload
We performed the analysis of variance and covariance on height, branch length, height to branch length ratio, and needle length measurements from thirty open-pollinated families of Pinus sylvestris L. from Siberia, Russia. This progeny trial was replicated on three sites in central Alberta,...
