Mammalian herbivores can carry out multiple tasks without interrupting food processing, but this possibility is not considered in existing foraging models. We develop a mechanistic functional response to account for herbivores' ability to search for their next food bite and walk away from...

Voltage-gated potassium channels are critical elements in providing functional diversity in nervous systems. The diversity of voltage-gated K+ channels in modern triploblastic metazoans (such as mollusks, arthropods and vettebrates) is provided primarily by four gene subfamilies (Shaker, Shal,...

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...

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...

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...

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...

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...

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 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...
