Bacteriophage T4 DNA polymerase was Inhibited by butylphenyl nucleotldes, aphldlcolin and pyrophosphate analogs, but with lower sensitivities than other members of the B family DNA polymerases. The nucleotides N2-{p-n-butylphenyl)dGTP (BuPdGTP) and 2-{p-n-butylanilino)dATP (BuAdATP) inhibited T4...

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...

Density-Dependent Effects and the Regulation of Crucian Carp Populations in Single-Species Ponds
Download1994
Tonn, W. M., Holopainen, I. J., Paszkowski, C. A.
Crucian carp (Carassius carassius) is often the only fish species present in small ponds of northern Europe. Such populations are typically at high densities and consist primarily of small, relatively slender, and short-lived fish; populations in multispecies assemblages in lakes display opposite...

Differential exudation of polypeptides by roots of aluminum-resistant and aluminum-sensitive cultivars of Triticum aestivum L. in response to aluminum stress
Download1994
Basu, A., Taylor, G. J., Basu, U.
Cultivars of Triticum aestivum differing in resistance to Al were grown under aseptic conditions in the presence and absence of Al and polypeptides present in root exudates were collected, concentrated, and analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Upon exposure to...

Basu, U., Basu, A., Taylor, G. J.
Three-day-old seedlings of an Al-sensitive (Neepawa) and an Al-resistant (PT741) cultivar of Triticum aestivum were subjected to Al concentrations ranging from a to 100 mu M for 72 h. At 25 mu M Al, growth of roots was inhibited by 57% in the Al-sensitive cultivar, whereas root growth in the...

Movement and settlement patterns of animal offspring, along with the costs of occupying familiar and unfamiliar habitats, have been inferred frequently, but rarely have they been documented directly. To obtain such information, we monitored the individual fates of 205 (94%) of the 219 offspring...

Veit, R. R., Banks, J. E., Holmes, E. E., Lewis, M. A.
Most of the fundamental elements of ecology, ranging from individual behavior to species abundance, diversity, and population dynamics, exhibit spatial variation. Partial differential equation models provide a means of melding organism movement with population processes and have been used...

Response of eight Canadian spring wheat (Triticum aestivum L.) cultivars to copper: Pollen viability, grain yield plant-1 and yield components
Download1994
Owuoche, J.O., Briggs, K.G., Taylor, G.J., Penney, D.C.
Eight Canadian spring wheat (Triticum aestivum L.) cultivars, Katepwa, Roblin, Park, Laura, Conway, Oslo, Columbus and Biggar., were tested in the field for copper (Cu) use efficiency. The experiment was conducted at Stony Plain, Alberta on an Orthic, Dark Grey, Chernozemic, Cu deficient 10.48 pg...
