We report myiasis by Lucilia silvarum with an overall prevalence of 0.9% in amphibian populations in boreal Alberta. In the period 1998–1999, we documented L. silvarum infestations in wild populations of wood frog (Rana sylvatica), boreal chorus frog (Pseudacris maculata), boreal toad (Bufo...

Myosin Assembly, Maintenance and Degradation in Muscle: Role of the Chaperone UNC-45 in Myosin Thick Filament Dynamics
Download2008
Myofibrillogenesis in striated muscle cells requires a precise ordered pathway to assemble different proteins into a linear array of sarcomeres. The sarcomere relies on interdigitated thick and thin filaments to ensure muscle contraction, as well as properly folded and catalytically active myosin...

Myosin VI contributes to synaptic transmission and development at the Drosophila neuromuscular junction
Download2011
Kisiel, M., Stewart, B.A., Campbell, S., Majumdar, D.
Background: Myosin VI, encoded by jaguar (jar) in Drosophila melanogaster, is a unique member of the myosin superfamily of actin-based motor proteins. Myosin VI is the only myosin known to move towards the minus or pointed ends of actin filaments. Although Myosin VI has been implicated in...

Na+/H+ exchange activity during phagocytosis in human neutrophils: Role of Fc7 receptors and tyrosine kinases
Download1996
Downey, G. P., Orlowski, J., Goss, G.G., Grinstein, S., Waddell, T. K., Fukushima, T.
Abstract. In neutrophils, binding and phagocytosis facilitate subsequent intracellular killing of microorganisms. Activity of Na+/H ÷ exchangers (NHEs) participates in these events, especially in regulation of intracellular pH (pHi) by compensating for the H ÷ load generated by the respiratory...

Natural disturbances and fish: Local and regional influences on winterkill of fathead minnows, Pimephales promelas, in boreal lakes
Download2003
We investigated the population dynamics of fathead minnow Pimephales promelas and the environmental factors of four small lakes in the boreal forest of Alberta, Canada, for 5 years to determine the influence of local and regional factors on the development of hypoxia and the occurrence of fish...

Hannon, Susan J., Cotterill, Susan E.
Several studies have documented elevated rates of nest predation for passerines and grouse in small forest patches and near anthropogenic edges. We examined patterns of predation on artificial nests in aspen (Populust remuloidesw) oodlots and fencerows surrounded by agricultural land in Alberta....

Nest Survival Patterns in Willow Ptarmigan: Influence of Time, Nesting Stage, and Female Characteristics
Download2007
Wilson, Scott, Hannon, Susan J., Martin, Kathy
Nest predation is the most important factor limiting reproductive success of Willow Ptarmigan (Lagopus lagopus), as it is for many bird species. Using program MARK, we examined patterns of daily nest survival in two widely separated populations of Willow Ptarmigan in Manitoba and British...

We investigate the inside dynamics of solutions to integrodifference equations to understand the genetic consequences of a population with nonoverlapping generations undergoing range expansion. To obtain the inside dynamics, we decompose the solution into neutral genetic components. The inside...

The Gobi Desert is famous for providing one of the worlds best preserved Cretaceous terrestrial faunas, including dinosaurs and mammals. Beginning with the Central Asiatic Expeditions in the 1920s, through the Polish-Mongolian Expeditions in the 1960s-1970s, Soviet-Mongolian Expeditions in 1970s,...
